Abstract

A connector assembly for rotational tools including a boss adapted to hold a tool and having a plurality of connecting projections, typically shafts. The shafts rotationally engage a driving means and longitudinally engage a locking ring that locks the boss, driving means and the locking ring together. This is achieved by the driving means and the locking ring having co-axially aligned bores allowing for the insertion of the shafts. The locking ring is further rotatable between two positions in one engaging the shafts for longitudinal movement and in the other allowing for free longitudinal movement of the shafts. Such an arrangement allows a tool mounted on the boss to be easily and quickly mountable and demountable. The connector assembly can be further used for the connection of static devices without any rotational motion imparted thereto.

The shaft may be convex, or another variation, which includes locking to the mandrel. The edge is used to connect the wheel rotation of the nineteenth to the twenty-seventh figure g to the driving device, such as the air car ^ to connect the larger rotating items to the end, the twenty-eighth figure and the twentieth are joined to On the axles. Other rotating devices, such as simple ratchet wrenches, do not apply the present invention. Although the present invention is related to connecting rotating moving equipment or articles, the present invention can also be used to insert a rotary driving tool away from a connector. Shi Yinn, 丨, quick-connection and disassembly of the static L-connector. The present invention is not limited to static use, and can also be applied and particularly applicable to all driving situations, and the joint can be used as a bearing for rotating motion. The need for fast, reliable and reliable joints is even clearer. Multiple sets of connectors can be used at the same time, such as large rods at the front of the car. Therefore, when driving in a pedestrian area or an urban area, the pole frame needs to be disassembled. The drawings and examples in this case will be described in detail. Please refer to FIGS.-5 to ′. The figure shows a connector, including a tool 12, namely a base 12, a base or a wheel, and a driving device 16. x The hole saw 12 includes a cylindrical body 8 having a cut 20 at one end. The other end of the hole saw 12 includes a screw hole (with internal thread) 22, and the outer surface of the hole saw body 18, near the screw hole 22, includes a shoulder 24 arranged on the circumference, such as a wrench tool (Not shown) can be engaged with the hole shifter 12 to perform a rotary motion.

Page 12 200419084 V. Description of the invention (9) The base 14 includes a disk 26. A flange 28, which is engraved with a thread (external thread), extends coaxially from the disc 26, and its size and shape can just mesh with the screw hole 22, so that the hole saw 12 can be tightly locked on the base. The disc 26 includes a shoulder 30 to engage a tool. Those skilled in the art can understand that when using ^ a tool 'one on the mine hole 1 § 12 and the other on the base 14, the hole saw 12 can be removed from the base. On the edge of the disc 26, two identical face bars 3 2 and 34 are extended in the opposite direction of the flange 28. Since these two shafts have the same function and are used in the same way, only one of them will be described in the following description. However, this description is also applicable to both shafts. The shaft 32 includes a post 36 extending from the disc 26, which is joined to the disc by well-known techniques ' e.g. With a screw or a press fit '. A short rod 40 is attached to the outer end of Zhu Zhao 3β, and the outer end of the pillar 36 has a chamfered cap 42. The diameter of the cap 42 is the same as the diameter of the cylinder 36. The mandrel 16 includes a longitudinal cone 46. The drill cone 46 is a rotary drill cone 46. The drill cone 46 extends in the opposite direction to an electric drill (not shown). Its position and size are such that the shaft is within the circular hole 52 and the shaft. The diameter of the 24 inserts can just accommodate the length and columns of the main body 44 of the shaft 24. Therefore, when the shaft 32 is inserted out of the body 44. The main body 44 extends coaxially and is fixed on the main body 44. On the main body 44 and the cutter shaft 48, which has a shoulder 50, can be inserted. The distal body 44 includes two circular holes 52 and 54. The rods 32 and 34 are inserted and passed through, and the shaft 32 is inserted in the circular hole 54. Generally, the circular holes 52 and 54 are mounted on the body 44. The length of the body 36 from the disc 26 to the short rod 40 is positioned in the body 44. The short rod 40 and the top cover 42

200419084 V. Description of the invention (10) The first ring ring or locking ring 56 is located on the top of the main body 44 and can be rotated between a second position and a second position. The ^ corresponds to the shape and size of π β βΛ. The dressing wheel 56 includes two shapes 眭 ^, corresponding openings 58 and 60. When the ring wheel 56 is located at the first office, the openings 58 and 60 are exactly the same. When the circular holes 52 and 54 are aligned and set to dagger, the opening is σ58, 6G is not the same as the circular holes 52 and 54. The person of this technology should know that when the ring wheel 56 and the body 44 are respected, they know: lever 40 And the top cover 42 can extend into the ring g56. ^ Ten backs are equal to the length of the short rod 40, because of the extension I !: Insertion: When the thickness of f 6 is relative to the thickness of the mouth, the nipple can be inserted into the mandrel 14 The inner cymbal / top cymbal 42 extends behind the plane of the ring wheel 56. At this time, it is completely inserted into the mandrel 16 and the ring wheel 56 is placed in the second position. The surface 62 and the inner edge 64 of the top cover 42 are sialed. Effectively prevent the soil of the shaft: the shaft, so the base 14 and the saw 12 and the mandrel 16 are effectively fixed, so that the saw 12 can be used for drilling. When the ring wheel 56 is biased to the second position, In other words, when the locked position =, a rotating force must be applied to rotate the ring wheel 56 to the first position in order to pull out the shafts 32 and 34. Generally, the rotation from the first position to the first position Spin The direction of rotation is the same as that of the drilling machine. A person skilled in the art should understand that this hole saw combination allows the hole saw to be installed on or removed from a mandrel 16 already installed on the drilling machine at a speed. Since the diameter of the hole saw 12 is independent of the size of the base 4 and the mandrel 6, 'As long as the ring 56 is rotated from the first position to the second position, a variety of hole saws can be simply reported. 12 is mounted on the mandrel 16 or removed from the mandrel 16. However, 'to make the installation work of the hole saw 14 to the mandrel 16 faster', the bottom surface of the ring 56 is the side facing the base 44 Opening 58 and 60. Page 14 200419084 V. Description of the invention (11) The peripheral edge 66 may be tapered or chamfered. When the shaft "34" is inserted into the circle 52 of the mandrel 16 in time, the top cover 42 forces the ring 56 to rotate To the first position. When the top cover protrudes from the top surface of the wheel 56, the biasing device will cause the ring wheel 56 to be locked in a biased position, thereby locking the base 14 and the hole saw 丨 2 to the mandrel 丨 6, so A self-closing design for the tool operator. y. The main body 44 is usually clamped by a drill 70 with a screw 70. However, those skilled in the art can use other general techniques to achieve this. / 、 The ring wheel 56 uses a buckle 72 to determine a fixed position. To prevent the retaining ring from closing the opening 58 or 6G, the pointed ring (not shown) or the retaining ring 7 2 can be locked with respect to the ring wheel 56. 'μ Refer to Figs. /, and 7, and it shows the locking ring or ring 56 in detail, especially its biased arrangement. The ring wheel includes a groove, and a biasing device is provided in the ring wheel. The biasing device is usually a spring (not shown, there is a pipe 76 at the two ends, and the pipe 76 has a guide pin 78, which can be: The check 78 meshes with a corresponding shaped hole (not shown) on the body 44 so that when the ring wheel 56 is placed on top of the body 44, the length of ΐ5 and Ϊ: 6, that is, the guide bolt 78 is movable. The distance, as shown in the two positions, limits the rotation of the ring wheel 56. As mentioned earlier, the hole saw is installed on the base or the wheel = device: it can be integrated with the draw rod to spray with the mandrel: Second, as shown in the eighth figure, the saw hole 80 80 can be seen, and its shape and function are as previously discussed. The shaft can be press-fitted, bolted or fixed on the mine hole 2 J, and Or with the mine; page 15 200419084 V. Description of the invention (12) Forming. This type of hole saw can be reduced by zero, such as punching system; made of == or metal binding, its good rod can be tmr processed If it is necessary to lock the shaft to the boring device, the shaft shoulders 86 are characterized by toilets and technicians. / 、 Eight joints, the shoulders are also the aforementioned solid For example, the unfavorable i-diameter is very large. As shown in the ninth figure, the hole drill 88 can be mounted, and the screws 92 and 94 are fixed to the base 9. Instead, the wires 92 and 94 pass through the bottom of the hole drill 88. The openings 96 and 98 are respectively 901. The ends of the shafts 100 and 102 are used to lock the saw 88 to the base ν0Βί in another embodiment, the base 14 in the first to fifth figures. The flange 28 is also longer than the known length. This allows two saws to be mounted on the same base 14. This is a quite practical feature, and the operator will want to use the existing hole Larger holes are drilled on the hole. The size of the smaller hole saw is the size of the existing hole. The small hole saw can be used as the actual guide center to cut larger holes in a symmetrical position. As shown, according to the preferred embodiment of the hole sawing device combination, it includes a smaller hole sawing tool 104, which longitudinally extends beyond the larger hole sawing device 106. The diameter of the smaller hole sawing device 104 According to its outer surface 108, it can be engaged with the inner surface of the hole 112 in the wall 112. When the hole device 106 is engaged with the wall 112, the hole saw 106 will not rotate, ensuring that A large hole 11 4 coaxial with the small hole 11 0 is cut out from the wall 11 2. The eleventh to thirteenth figures show a combination of a hole saw according to another preferred embodiment of the present invention. In this embodiment, the saw The hole holder 12 and the base 26 are of the same type as previously discussed. However, the total length of the shafts 116 and 118 is shorter, and the shafts are shorter.

Page 16 200419084 V. Description of the invention (13) It also has a short rod 40 and a top cover 42. Assuming that the base is the same size as the ring wheel, the short shaft does not protrude behind the ring wheel as in the previous embodiment. This can be clearly seen from the eleventh and thirteenth drawings, and the shafts 116 and 118 do not protrude beyond the top surface 120 of the ring wheel 122. Since the shaft rods 116 and 118 do not protrude from the ring wheel 56, the aforementioned method of locking the mandrel to the shaft rod is no longer applicable. Therefore, near the top surface 12 o of the ring wheel 56, the openings 12 and 12 are partially enlarged to form an inner shoulder § 2 to engage the inner edge 64 of the top cover 42. Therefore, the openings 124 and 126 of the ring wheel 56 are circular cross-sections, which are only the length of the short rod 40 from the bottom surface 68 of the ring wheel 56. Then, the opening 124 is enlarged to rotate the bad wheel 56 to make the shaft jig and 11 8 Lock or release. The top cover can be stopped very quickly in the actual locking ring. The class reads the advantages of the problem of rotating the device to the attached embodiment. It is provided in the buckle embodiment. However, when a lock is used in the figure, it seems that the lock is present. When using connector on the head. Avoiding the use of recesses or the like also avoids the risk of the top cover. Moreover, provide that the diameter of the top cover can be smaller than the openings 124 and 126. The wall is not indicated in the formula, but nails are used to ensure that the locking ring is not as good as the grinding wheel, and its rotating speed tight ring can also be included in this design. The invention should be understood The main one is to install the staggerer to the case. However, other means to prevent the ring 72 from rotating prevent the drill bit from clamping, reducing a more beautiful appearance. The diameter of the shaft to make multiple materials. Understandable will come out. The speed can reach every minute. In this case, the use of a rotary hand tool is also similar in some cases when the clock is rotated 18, 000. The adapter's display drill should be properly installed

Page 17 200419084 V. Description of the invention (14) For example, as shown in the fourteenth figure, the present invention can also be used to install a polishing wheel 130 to a base 26. The polishing wheel 130 has a thread axis 132 and can be locked to On the threaded flange 28, the structure of the joint and the joint described above are only slightly changed, for example, it does not have a shaft shoulder 86, which helps to lock the shaft to the hub. Other tools, such as the wire brush 1 34, can also be rotatably mounted to a threaded flange using a threaded collar 1 3 6 as shown in the fifteenth figure. The collar 136 clamps the center of the wire brush 134 Round seat 138.

Other changes of the joint of the present invention include the change of the mandrel, so that the locking ring 56 can be accommodated in the mandrel, and the outer end thereof includes a screw hole 1 40, so that the mandrel can be screwed to a shaft or the like. , The other parts are exactly the same as described above or a combination of them. Therefore, as shown in the sixteenth figure, the joint can also use the collar 136 to clamp the grinding wheel 142 on the hub 14. Those skilled in the art should now understand that this problem-solving solution can quickly install or remove a tool to a drive or mandrel, which uses a locking ring to engage the wheel hub on which the tool is installed to prevent the tool from being damaged. The mandrel is separated, and the mandrel can drive the hub and the tool to rotate. So it is clear that other shapes of the wheel compared to the mandrel are also within the scope of the present invention, including as shown in Figures 17 and 18.

Figure 17 shows a hollow hub 144 with a cylindrical outer sleeve or sleeve 146 extending from one direction of the base, and a threaded protrusion 148 extending from the opposite longitudinal direction. The flange 148 can be connected to a tool . Extend symmetrically from the top end 150 of 146—the axially symmetrical shafts 152 and = two = and 154 and the openings 156 and 158 on the top of the mandrel 160 and the locking ring 162 are knife-to-axis, and the locking mechanism is coaxial. Same as before.

Page 18 200419084 V. Description of the invention (15) The size of the tube 146 can be slid on the inner end 164 of the mandrel, and the top end 150 of the sleeve 146 abuts on the inner shoulder 166 of the mandrel 160. This joint is used to support the boring device, so a drill cone 16.8 is installed in the mandrel and fixed with screws 17o. The mandrel includes a shaft 172 which can provide rotational torque when the shaft is connected to a driving device such as an electric drill (not shown). Figure 18 shows another configuration of this connector, which has the same function. The hub 174 is also hollow, and has a bottom 176 and a set of tubes 78, the tube 178 has a top end 180. A pair of flanges 182 extend from the top end 180 of the sleeve. The female flange 182 includes a rod body 184 and a tapered end 186. Each rod body 184 has a corresponding cutout 1 8 8 to form an inner shoulder 190. The tapered end 1 $ 6 provides rotational force to rotate the locking ring 192 (clockwise in the figure), so that the flange 182 slides through the groove of the locking ring 192 to the recess of the mandrel. Slot 196 until the inner shoulders 19 of the two flanges pass through the grooves 194 of the locking ring 192, and the locking ring 192 will deflect to return to its deflecting position or counterclockwise direction. At this time, the inner shoulder 190 abuts on the top surface 198 a of the locking ring 192. The south of the cut 188 is the same as the thickness of the lock ring M2, so that the hub 174 is tightly attached to the mandrel 198. The width of the flange 182 near the cutout 188 is the same as the circumferential width of the mandrel groove 196. Therefore, when a rotating force is applied to the shaft 198b of the mandrel, the mandrel rotates, and the rotational torque passes through the mandrel groove to the hub flange, so that the torque is applied to the hub. When removing the joint, you only need to rotate the locking ring 192 very easily, f grab the groove 194 of the L tight ring 192 and the recess of the mandrel 198 to align with the L edge 182, which can be easily pulled out. And install it on the wheel

Description of the invention (16) So far, from the foregoing description, a can be biased, although; this is a preferred feature, but in some cases, the lock ring is in The two Syrians need not be biased. In the position, the wheel is relatively locked to the mandrel, and == it is enough to move. The-position can be half-locked by, for example, a ball bearing, because the wheel is fixed; :: For larger applications. If the head can be used to install a car tire to the same principle as described in wheel 1, this book is tolerated: ft. 9 to 22, existing tires can be refurbished and improved a ^ 202 Therefore, one side of the wheel 200 can include A plurality has a screw connection: Ϊ :: As mentioned above, there are a plurality of aggressors on the other side: the charm / longitudinal extension in the opposite direction.
