Description

多向驅動頭 Multi-directional drive head

本發明係關於鬆弛及鎖緊扣件(例如螺絲及螺帽)的工具，特別是關於一種防滑的多向驅動頭，其能夠在取出或鎖緊扣件的過程中，防止起子頭傷害扣件或從扣件滑脫。 The present invention relates to a tool for loosening and locking fasteners (such as screws and nuts), and more particularly to a non-slip multi-directional driving head, which can prevent the bit from damaging the fasteners during the process of removing or locking the fasteners or slip off the fastener.

六角螺栓、螺帽、螺絲及其他類似的含螺紋扣件，藉由與互補的螺紋(通常就是所謂的母螺紋)結合，而將複數的零件固定在一起。此類扣件的結構一般包含：一個具有外螺紋的圓柱形軸部、及一個在軸部尾端的頭部。此一外螺紋與一個互補的母螺紋結合，而將此一扣件固定並同時固定相關的零件，其中母螺紋通常藉由攻牙進入一個孔洞或螺帽而形成。扣件藉由其頭部接受一個外部的扭力，而被轉動或驅動進入母螺紋。頭部的形狀被製造成可以讓一個外部的工具，例如一個板手，施加扭力於扣件，以旋轉扣件，以某種程度結合於互補的母螺紋。此類的扣件簡單、便宜、非常有效，因此在現代的社會中普遍地被使用。 Hex bolts, nuts, screws, and other similar threaded fasteners hold multiple parts together by combining with complementary threads (often called female threads). The structure of this type of fastener generally includes: a cylindrical shaft with external threads, and a head at the end of the shaft. This external thread is combined with a complementary female thread, which is usually formed by tapping into a hole or a nut, to secure the fastener and the associated component at the same time. The fastener is turned or driven into the female thread by receiving an external torsion force on its head. The head is shaped to allow an external tool, such as a wrench, to apply torque to the fastener to rotate the fastener to some extent engage the complementary female threads. Such fasteners are simple, inexpensive, and very effective, and are therefore commonly used in modern society.

使用此類扣件常見的問題之一是：無論扣件是公或母，工具常常會在頭部滑動。其原因有可能是：工具或扣件磨損、工具或扣件鏽蝕、過度扭緊扣件、扣件的頭部損壞。 One of the common problems with using this type of fastener is that the tool often slips on the head whether the fastener is male or female. Possible causes are: tool or fastener wear, tool or fastener corrosion, over-tightening of fasteners, damage to the head of the fastener.

本發明的主要目的是在提供一種多向驅動頭，其可以讓扭力有效率地施加於承窩扣件。本發明的多向驅動頭包含至少一個螺絲起子頭本體。螺絲起子頭本體更包含：複數個側撐壁、一個第一基面、及一個第二基面。複數個側撐壁徑向地環繞螺絲起子頭本體的一條旋轉軸。複數個側撐壁中的每一個更包含：一個第一側緣、一個第二側緣、一個側面、及至少一個結合穴。結合穴產生夾持點，以防止螺絲起子頭本體及承窩扣件之間產生滑移的現象。結合穴更包含：一個角隅驅動部及一個凹入部。角隅驅動部鄰近第一側緣；凹入部隔著角隅驅動部相對於第一側緣。 The main purpose of the present invention is to provide a multi-directional drive head which can efficiently apply torsional force to the socket fastener. The multi-directional drive head of the present invention includes at least one screwdriver bit body. The screwdriver head body further comprises: a plurality of side support walls, a first base surface, and a second base surface. A plurality of side struts radially surround an axis of rotation of the bit body. Each of the plurality of side support walls further comprises: a first side edge, a second side edge, a side surface, and at least one combination hole. The combination hole creates a clamping point to prevent slippage between the screwdriver head body and the socket fastener. The combination hole further includes: a corner driving part and a concave part. The corner driving portion is adjacent to the first side edge; the concave portion is opposite to the first side edge across the corner driving portion.

本發明係一種可以實質上消除滑動的起子頭設計。本發明的設計包含數個部分。此些部分的整體作用可以嚙合扣件的頭部，因而可以有效地在起子頭及扣件頭部之間傳遞扭力。傳統的螺栓起子可能會用到原本不需的要工具以及鑽孔。本發明則避免了這些問題。 The present invention is a bit design that substantially eliminates slippage. The design of the present invention consists of several parts. The integral action of these parts engages the head of the fastener, thereby effectively transferring torque between the bit of the driver and the head of the fastener. Traditional bolt drivers may use tools and drill holes that are not otherwise required. The present invention avoids these problems.

隨著電動螺絲起子及電鑽的發展，人們已經普遍地使用電動工具施加扭力以移除扣件。本發明提供一種雙頭的起子頭，其可以順時針或逆時針地施加扭力於扣件，以鎖緊或鬆弛扣件。 With the development of power screwdrivers and drills, it has become common to use power tools to apply torque to remove fasteners. The present invention provides a double-ended screwdriver bit, which can apply torsion force to the fastener clockwise or counterclockwise to lock or loosen the fastener.

本發明中，大部分的起子頭具有一個標準的四分之一英寸六角形夾持端，但也可以是不限於是方形、六角形、或星形的夾持端。 In the present invention, most driver bits have a standard one-quarter inch hex gripping end, but may have a gripping end that is not limited to square, hex, or star.

首先要特別說明的是：本說明書所使用的圖示僅是用於說明本發明的某些實施例，本發明的範圍並不受該些圖示的限制。 First of all, it should be noted that the drawings used in this specification are only used to illustrate some embodiments of the present invention, and the scope of the present invention is not limited by these drawings.

本發明係關於扭力工具的配件，特別是關於一種多夾持點套筒起子頭，其係一種螺絲起子頭或螺絲驅動頭。比起其他相似尺寸的習知螺絲起子頭，本發明可以施加較大扭力於承窩扣件，而不會傷害承窩扣件頭部或起子頭工具。本發明的功效是藉由具有複數特徵的嚙合結構而達成，這些特徵使嚙合結構能有效地夾持住承窩扣件的頭部。本發明是一種套筒起子頭，其可與多種的扭力工具相容，這些扭力工具包括：傳統的電鑽、可 容納起子頭的螺絲起子、套筒扳手、套筒起子，但這些扭力工具不限於是上述的扭力工具。 The present invention relates to accessories for torque tools, and more particularly to a multi-pinch socket bit, which is a screwdriver bit or screw driver bit. Compared to other conventional screwdriver bits of similar size, the present invention can apply greater torque to the socket fastener without damaging the socket fastener head or the bit tool. The effects of the present invention are achieved by engaging structures having a plurality of features that enable the engaging structures to effectively hold the heads of the socket fasteners. The present invention is a socket bit, which is compatible with a variety of torque tools, including: traditional electric drills, screwdrivers that can accommodate a bit, socket wrenches, socket drivers, but these torque tools are not limited to It is the torque tool mentioned above.

請參照圖1，其為本發明最簡單的一個實施例。在此一實施例，本發明包含：至少一個螺絲起子頭本體1。螺絲起子頭本體1是一支柄桿，其可與承窩扣件結合，例如：承窩螺絲及承窩螺桿，以便快速地將扭力施加於承窩扣件。螺絲起子頭本體1更包含：複數個側撐壁2、一個第一基面11及一個第二基面12。一般而言，螺絲起子頭本體1是一個由高強度金屬所構成的球狀稜柱體。複數個側撐壁2與承窩扣件結合，以便有效地將扭力由扭力工具傳遞到承窩扣件。第一基面11及第二基面12隔著複數個側撐壁2彼此相對，且第一基面11及第二基面12垂直於複數個側撐壁2，而形成稜柱狀的螺絲起子頭本體1。 Please refer to FIG. 1 , which is the simplest embodiment of the present invention. In this embodiment, the present invention includes: at least one screwdriver head body 1 . The screwdriver head body 1 is a shank, which can be combined with socket fasteners, such as socket screws and socket screws, so as to quickly apply torque to the socket fasteners. The screwdriver head body 1 further comprises: a plurality of side support walls 2 , a first base surface 11 and a second base surface 12 . Generally speaking, the head body 1 of the screwdriver is a spherical prism body made of high-strength metal. A plurality of side braces 2 are combined with the socket fasteners so as to efficiently transmit torque from the torque tool to the socket fasteners. The first base surface 11 and the second base surface 12 are opposite to each other across a plurality of side support walls 2 , and the first base surface 11 and the second base surface 12 are perpendicular to the plurality of side support walls 2 to form a prismatic screwdriver head body 1.

請參照圖1及圖示4。每一個側撐壁2更包含：一個第一側緣3、一個第二側緣4、一個側面5及至少一個結合穴6。複數個側撐壁2徑向地環繞螺絲起子頭本體1的一條旋轉軸13，而產生與承窩扣件剖面互補的形狀。側撐壁2的數量隨著承窩扣件形狀改變，以便和承窩扣件的形狀互補。在本發明的一個實施例，側撐壁2的數量是6，而產生螺絲起子頭本體1的剖面是一個六角形。在本發明的另一個實施例，側撐壁2的數量是4，而產生螺絲起子頭本體1的剖面是一個四角形。 Please refer to Figure 1 and Figure 4. Each side support wall 2 further comprises: a first side edge 3 , a second side edge 4 , a side surface 5 and at least one combination hole 6 . A plurality of side support walls 2 radially surround a rotation axis 13 of the head body 1 to produce a shape complementary to the cross-section of the socket fastener. The number of side braces 2 varies with the shape of the socket fastener so as to complement the shape of the socket fastener. In one embodiment of the present invention, the number of side braces 2 is 6, and the cross-section that produces the head body 1 of the screwdriver is a hexagon. In another embodiment of the present invention, the number of side support walls 2 is 4, and the cross-section of the body 1 of the screwdriver bit is a quadrangle.

側面5頂靠著承窩扣件，尤其是承窩扣件頭部的側壁。第一側緣3和第二側緣4隔著側面5彼此相對。從上視圖或下視圖來看，第一側緣3和第二側緣4構成螺絲起子頭本體1的稜角。結合穴6凹陷入側面5，因而在側面5產生額外的夾持點或夾持齒。額外的夾持點是產生於結合穴6以及相鄰的側 緣，其中相鄰的側緣可以是第一側緣3或第二側緣4，尤其是最靠近結合穴6的側緣。結合穴6在螺絲起子頭本體1上自第一基面11朝著第二基面12延伸。於是，額外的夾持點在螺絲起子頭本體1的長度方向延伸，使螺絲起子頭本體1及承窩扣件之間可以具有最大的夾持結合力量。在一個實施例，結合穴6自第一基面11朝著第二基面12逐漸變細。請參照圖6。結合穴6更包含：一個角隅驅動部7及一個凹入部10。角隅驅動部7是一條直線，其與相鄰的側緣共同產生額外的夾持點或夾持齒，這些夾持點直接接觸承窩扣件的內側壁。在一個較佳實施例，角隅驅動部7鄰近第一側緣3。額外的夾持齒咬入承窩扣件的內側壁，於是扭力就可以有效地傳遞到承窩扣件。凹入部10是一個具有半圓形剖面的缺口，其提供餘裕空隙給承窩扣件的內側壁，如此可以確保額外的夾持齒是螺絲起子頭本體1唯一頂咬住承窩扣件的部分。為此，凹入部10鄰近角隅驅動部7，並且相對於第一側緣3。凹入部10可具有其他形狀的剖面。其他形狀的剖面包括但不限於是：半正方形、半長方形、及半橢圓形的剖面。請參照圖6及圖示8。在一個較佳實施例，角隅驅動部7的一個第一側邊8與第一側緣3重疊，以產生一個尖銳的角。更且，角隅驅動部7的一個第二側邊9鄰近於凹入部10。側面5及凹入部10之間的部分是作為一個樞軸點，其決定何時額外的夾持齒咬住承窩扣件。當內側壁滑過側面5及凹入部10的交接處的時候，也就是角隅驅動部7頂咬住承窩扣件的內側壁的時候。 The side 5 bears against the socket fastener, in particular the side wall of the head of the socket fastener. The first side edge 3 and the second side edge 4 are opposed to each other across the side surface 5 . From the top view or bottom view, the first side edge 3 and the second side edge 4 constitute the corners of the screwdriver bit body 1 . The binding pockets 6 are recessed into the side faces 5, thus creating additional gripping points or gripping teeth on the side faces 5. Additional gripping points are created in the binding pocket 6 and the adjacent side edge, wherein the adjacent side edge may be the first side edge 3 or the second side edge 4, especially the side edge closest to the binding pocket 6. The coupling cavity 6 extends from the first base surface 11 toward the second base surface 12 on the head body 1 of the screwdriver. Therefore, the additional clamping points extend in the length direction of the screwdriver bit body 1, so that the screwdriver bit body 1 and the socket fastener can have the maximum clamping force. In one embodiment, the bonding cavity 6 tapers gradually from the first base surface 11 toward the second base surface 12 . Please refer to Figure 6. The coupling hole 6 further includes: a corner driving part 7 and a concave part 10 . The corner drive 7 is a straight line which, together with the adjacent side edges, creates additional gripping points or gripping teeth which directly contact the inner side walls of the socket fastener. In a preferred embodiment, the corner driving portion 7 is adjacent to the first side edge 3 . The additional gripping teeth bite into the inner sidewall of the socket fastener so that torque can be efficiently transferred to the socket fastener. The recess 10 is a notch with a semi-circular cross-section, which provides extra clearance for the inner side wall of the socket fastener, so as to ensure that the extra clamping teeth are the only part of the screwdriver head body 1 that bites the socket fastener . To this end, the recessed portion 10 is adjacent to the corner drive portion 7 and opposite to the first side edge 3 . The recessed portion 10 may have other shaped cross sections. Other shaped cross-sections include, but are not limited to, semi-square, semi-rectangular, and semi-elliptical cross-sections. Please refer to FIG. 6 and FIG. 8 . In a preferred embodiment, a first side edge 8 of the corner driving portion 7 overlaps the first side edge 3 to create a sharp corner. Furthermore, one second side edge 9 of the corner driving portion 7 is adjacent to the concave portion 10 . The portion between side 5 and recess 10 serves as a pivot point that determines when the additional clamping teeth engage the socket fastener. When the inner side wall slides over the junction of the side surface 5 and the concave portion 10, that is, when the corner driving portion 7 bites the inner side wall of the socket fastener.

本發明可以做為一根垂直的起子頭使用，並且具有額外的夾持力。當額外的夾持齒咬入承窩扣件的內側壁，本發明在旋轉時並不會發生 滑移的現象。更且，當本發明在反方向旋轉的時候，側面5可以提供足夠的咬合力以旋轉承窩扣件。所以，本發明是一個多方向的起子頭。 The present invention can be used as a vertical driver bit with extra gripping force. When the additional clamping teeth bite into the inner side wall of the socket fastener, the present invention does not slip during rotation. Furthermore, when the present invention is rotated in the opposite direction, the side 5 can provide sufficient occlusal force to rotate the socket fastener. Therefore, the present invention is a multi-directional screwdriver bit.

請參照圖8。在一實施例，本發明更包含複數個間歇式側壁19。每一個間歇式側壁19是一個平坦表面，其結合承窩扣件，功能類似傳統的螺絲起子頭設計。複數間歇式側壁19徑向地環繞螺絲起子頭本體1的旋轉軸13。複數個間歇式側壁19穿插於複數個側撐壁2之間。於是，複數個間歇式側壁19及複數個側撐壁2交替的地分佈於螺絲起子頭本體1的徑向，並且環繞螺絲起子頭本體1的旋轉軸13。 Please refer to Figure 8. In one embodiment, the present invention further includes a plurality of intermittent side walls 19 . Each intermittent side wall 19 is a flat surface that incorporates a socket fastener and functions like a conventional screwdriver bit design. A plurality of intermittent side walls 19 radially surround the axis of rotation 13 of the bit body 1 . A plurality of intermittent side walls 19 are inserted between the plurality of side support walls 2 . Therefore, a plurality of intermittent side walls 19 and a plurality of side support walls 2 are alternately distributed in the radial direction of the bit body 1 , and surround the rotating shaft 13 of the bit body 1 .

本發明更包含一個附裝構造，其可讓一個外部扭力工具附裝於螺絲起子頭本體1，並且經由螺絲起子頭本體1將扭力傳遞到承窩扣件。請參照圖1。本發明更包含一個附裝構造本體14。附裝構造本體14的中心位於旋轉軸13，而且沿著旋轉軸13分佈。因此，附裝構造本體14的旋轉軸與螺絲起子頭本體1的旋轉軸13完全重疊。附裝構造本體14連接於第二基面12。附裝構造本體14較為優選的截面形狀是六角形，以便安裝於外部扭力工具的陰性附裝構造(附裝孔)，扭力工具可以是但不限於是：電鑽、扭力板手、氣動鑽、套筒螺絲起子、或其他的扭力工具。 The present invention further includes an attachment structure that allows an external torque tool to be attached to the bit body 1 and transmit torque to the socket fastener via the bit body 1 . Please refer to Figure 1. The present invention further includes an attached structural body 14 . The center of the attachment structure body 14 is located on the rotation axis 13 and is distributed along the rotation axis 13 . Therefore, the rotation axis of the attachment structure body 14 completely overlaps the rotation axis 13 of the bit body 1 . The attachment structure body 14 is connected to the second base surface 12 . The preferred cross-sectional shape of the attachment structure body 14 is hexagonal, so as to be mounted on the female attachment structure (attachment hole) of the external torque tool. The torque tool can be but not limited to: electric drill, torque wrench, pneumatic drill, sleeve screwdriver, or other torque tool.

請參照圖7。在一實施例，本發明更包含一個結合孔16。結合孔16可以讓本發明附加於一個外部扭力工具的陽性附裝構造，例如套筒板手或螺絲起子。結合孔16從相對於螺絲起子頭本體1的方向，沿著旋轉軸穿入附裝構造本體14。結合孔16的形狀可以接受套筒板手的陽性附裝構造。結合孔16的形狀較佳為正方形，因為大部分套筒板手使用正方形的附裝構造。在此一實施例，附裝構造本體14的形狀較佳為圓柱形。在其他實施例，結 合孔16及附裝構造本體14的形狀可以隨著扭力工具的設計及附裝的方法而變化。 Please refer to Figure 7. In one embodiment, the present invention further includes a coupling hole 16 . The coupling hole 16 allows the present invention to be attached to a male attachment configuration of an external torque tool, such as a socket wrench or screwdriver.

The engagement hole 16 is shaped to accept the male attachment configuration of the socket wrench. The shape of the engagement hole 16 is preferably square since most socket wrenches use a square attachment configuration. In this embodiment, the shape of the attachment structure body 14 is preferably cylindrical. In other embodiments, the shape of the engagement hole 16 and attachment feature body 14 may vary with the design of the torque tool and the method of attachment.

請參照圖2及圖3。在一實施例，本發明被製造成一個雙頭的螺絲起子頭，可同時提供順時針的螺絲起子頭本體1及逆時針的螺絲起子頭本體1。在此一實施例，螺絲起子頭本體1包含：一個第一螺絲起子頭本體17及一個第二螺絲起子頭本體18。附裝構造本體14的剖面較佳為六角形。附裝構造本體14的中心位於第一螺絲起子頭本體17的旋轉軸13，而且沿著第一螺絲起子頭本體17的旋轉軸13分佈。因此，附裝構造本體14的旋轉軸與第一螺絲起子頭本體17的旋轉軸13完全重疊。附裝構造本體14連接於第一螺絲起子頭本體17的第二基面12。第二螺絲起子頭本體18與第一螺絲起子頭本體17及共享附裝構造本體14，且第二螺絲起子頭本體18與第一螺絲起子頭本體17同心。類似於傳統的雙頭螺絲起子頭的設計，第二螺絲起子頭本體18連接於附裝構造本體14而且相對於第一螺絲起子頭本體17。類似第一螺絲起子頭本體17，附裝構造本體14連接於第二螺絲起子頭本體18的第二基面12。此一實施例在附裝構造本體14兩端的任一端形成螺絲起子頭本體1。請參照圖4。第一螺絲起子頭本體17用於鎖緊承窩扣件，也就是說第一螺絲起子頭本體17是順時針版的螺絲起子頭本體。請參照圖5。第二螺絲起子頭本體18用於釋放承窩扣件，也就是說第二螺絲起子頭本體18是逆時針版的螺絲起子頭本體。為此，第一螺絲起子頭本體17及第二螺絲起子頭本體18，相對於附裝構造本體14的一個中央縱切面15，彼此互為鏡像。中央縱切面15在長度的方向將附裝構造本體14平分為兩個相同的部分。當第一螺絲起子頭本體17在承窩扣件內順時針旋轉時，第一螺絲起子頭本體17的額外夾持齒就會進行頂咬 的動作，如圖4所示。當第二螺絲起子頭本體18在承窩扣件內逆時針旋轉時，第二螺絲起子頭本體18的額外夾持齒就會進行頂咬的動作，如圖5所示。 Please refer to FIG. 2 and FIG. 3 . In one embodiment, the present invention is fabricated as a double-headed screwdriver bit, which can provide a clockwise screwdriver bit body 1 and a counterclockwise screwdriver bit body 1 at the same time. In this embodiment, the screwdriver bit body 1 includes a first screwdriver bit body 17 and a second screwdriver bit body 18 . The cross section of the attachment structure body 14 is preferably hexagonal. The center of the attachment structure body 14 is located on the rotation axis 13 of the first bit body 17 , and is distributed along the rotation axis 13 of the first bit body 17 . Therefore, the rotation axis of the attachment structure body 14 completely overlaps the rotation axis 13 of the first bit body 17 . The attachment structure body 14 is connected to the second base surface 12 of the first screwdriver bit body 17 . The second bit body 18 shares the attachment structure body 14 with the first bit body 17 and the second bit body 18 is concentric with the first bit body 17 . Similar to the design of a conventional double-ended screwdriver bit, the second screwdriver bit body 18 is attached to the attachment feature body 14 and is opposite to the first screwdriver bit body 17 . Similar to the first bit body 17 , the attachment structure body 14 is connected to the second base surface 12 of the second bit body 18 . This embodiment forms the bit body 1 on either end of the two ends of the attachment structure body 14 . Please refer to Figure 4. The first screwdriver bit body 17 is used for locking the socket fastener, that is to say, the first screwdriver bit body 17 is a clockwise version of the screwdriver bit body. Please refer to Figure 5. The second screwdriver bit body 18 is used to release the socket fastener, that is to say, the second screwdriver bit body 18 is a counterclockwise version of the screwdriver bit body. For this purpose, the first bit body 17 and the second bit body 18 are mirror images of each other with respect to a central longitudinal section 15 of the attachment structure body 14 . The central longitudinal section 15 bisects the attachment construction body 14 lengthwise into two equal parts. When the first bit body 17 is rotated clockwise in the socket fastener, the extra clamping teeth of the first bit body 17 will perform a top-biting action, as shown in FIG. 4 . When the second screwdriver bit body 18 rotates counterclockwise in the socket fastener, the extra clamping teeth of the second screwdriver bit body 18 will perform a top-biting action, as shown in FIG. 5 .

在一實施例，類似於傳統的螺絲起子頭，螺絲起子頭本體1自第二基面12朝著第一基面11逐漸變細，而形成一個比較尖銳的尾端。在另外一個實施例，本發明是一個球狀的螺絲起子頭。在這個實施例，每一個側撐壁2的側面5更包含：一個突出面及一個凹入面。突出面鄰近於第一基面11，於是所有側撐壁2的突出面共同形成了一個球面的形狀。凹入面相對於第一基面11而且鄰近於突出面；複數個側撐壁2的個凹入面也參與球形的產生。凹入面也提供餘裕空隙讓螺絲起子頭本體1以一個角度結合於承窩扣件。突出面及凹入面沿著螺絲起子頭本體1的旋轉軸13分佈，使球形位於螺絲起子頭本體1的終端。在本發明的一個較佳實施例，突出面及凹入面的曲率、長度、及高度都相同。於是，整個螺絲起子頭本體1成為一個球狀構造。這讓使用者可以將螺絲起子頭本體1以某一個角度結合於承窩扣件，特別適合使用在不容易施工位置的扣件。 In one embodiment, similar to a conventional screwdriver bit, the screwdriver bit body 1 tapers from the second base surface 12 toward the first base surface 11 to form a relatively sharp end. In another embodiment, the present invention is a spherical screwdriver bit. In this embodiment, the side surface 5 of each side support wall 2 further comprises: a protruding surface and a concave surface. The protruding surface is adjacent to the first base surface 11 , so that the protruding surfaces of all the side braces 2 together form a spherical shape. The concave surface is opposite to the first base surface 11 and adjacent to the protruding surface; the concave surfaces of the plurality of side braces 2 also participate in the generation of the sphere. The concave surface also provides a margin for the screwdriver bit body 1 to engage with the socket fastener at an angle. The protruding surface and the concave surface are distributed along the rotation axis 13 of the head body 1 , so that the ball is located at the terminal end of the head body 1 . In a preferred embodiment of the present invention, the curvature, length, and height of the protruding surface and the concave surface are the same. Thus, the entire bit body 1 has a spherical structure. This allows the user to combine the screwdriver head body 1 with the socket fastener at a certain angle, which is especially suitable for fasteners that are not easy to construct.

在一實施例，結合穴6包含：一個第一穴及一個第二穴。第一穴及第二穴隔著側面5彼此相對。更且，第一穴及第二穴隔安排為朝向彼此。於是，兩個額外的夾持點就產生在每一個側撐壁2。因此，螺絲起子頭本體1在旋轉的時候會頂咬住承窩扣件。 In one embodiment, the combination hole 6 includes: a first hole and a second hole. The first hole and the second hole face each other across the side surface 5 . Furthermore, the first hole and the second hole spacer are arranged to face each other. Thus, two additional clamping points are created at each side stay 2 . Therefore, the head body 1 of the screwdriver bit bites against the socket fastener when it is rotated.
