Description of the invention (2) = below: pendulum 'makes the conventional movable wrench not suitable for narrow-down operation, which greatly reduces the operating performance of the wrench. The upper part of the pivot joint 12 is shown in the figure and the second figure. The right half of the pivot end 12 has a smooth edge. = 邛 122 must be slightly lower than the tooth root of the latching portion 121, so that the restraining member 3 can be smoothly left and right. Slip. If the adjusting portion 122 is set slightly higher than the tooth root of the latching portion ΐ2m, the restraining member 3 will be stopped by the regulating portion 122 and cannot slide to the smooth edge surface of the regulating portion 122. Therefore, the thickness of the adjusted portion is reduced more than that of the card portion 121, and the meat L between the adjustment portion 122 and the shaft hole 13 is reduced. Referring to the second figure, the force state of the pivot end 12 of the wrench body i during the pulling operation is shown. 'When the wrench is turned clockwise, the force segment ⑴ of the wrench body 1 will directly bear. Pull power. However, the meat thickness l of the force section Ub is greatly reduced due to structural restrictions. Therefore, when the pulling force applied to the swing head wrench is excessive, the meat wall of 13b ☆ is liable to generate cracks 14 or damage, which seriously affects The torque value of Chengwen held by the wrench. For the setting of the positioning structure, the most important force value of the wrench is sacrificed. The lack of all the drivers of this learning activity is really necessary for research and development. The present invention intends to eliminate or at least alleviate the problems encountered in the prior art. [Summary of the Invention] The problem to be solved by the "improved structure of the movable swing wrench" of the present invention is that the wrench body of the conventional swing wrench can only be used with the grip.

Operation of invention description (3). Moreover, the pivot end of the wrench head body is limited by the setting of the latch structure, so that the meat thickness between the adjusting portion and the pin hole is relatively reduced. When the pulling force applied to the swinging head wrench is large, the meat of the force section of the driving head is large. The wall is prone to cracks or damage, which seriously affects the torque value that the wrench can withstand. = Objective, advantages and novel features of the present invention will become more apparent from the related drawings. The present invention provides a movable pendulum pivot section provided with teeth, the first arc surface of which is not south of the tooth root , Its thickness, the circular arc surface is not lower than the thickness of the flesh between the roots of the teeth is L1 (L1 > L). When the thick meat wall of the application section can withstand greater force effects, the tooth system that the swinging head wrench can withstand is more convex, and the height of the tooth root will not be limited by the stopper of the catch. This makes the swing head wrench more suitable for improving the operating performance of the wrench. The improved structure of the head wrench, the second section of the driving head is provided with a relatively narrow arc surface, the circular solitary surface of the third section is full meat, and the arc surface and pin hole of the second section are driven by When swinging the wrench, the torque value of the wrench is not easy to be cracked or damaged. And the side of its latch is on the left and right end faces, so the driving head can generate a single side 90 with the handle. The left side is used for operation in a small space. The big duck is inserted in the following detailed description. [Embodiment] and the hand 30 includes:-the drive head 4. , -㈣ is provided on the driving head 40 and the grip end is pivoted on the handle 50.

Description of the invention (5) A blocking edge 61 is provided at the two ends, and a bead hole 62 is provided. The teeth of the other convex external teeth 63 'of the latching member 60 are higher than the left and right end faces 64, 65. See also ... Figure 8 shows that the teeth 6 3 of the card engine g 0 fit into the teeth of the driving section 431, and the relative position between the driving head 40 and the grip 50 is limited and set on the grip. The steel ball 56 in the handle 50 is locked by the elastic body 57 and locked in the bead hole 6 / of the 60, so that the latching member 60 can obtain a precise positioning. When the handle is pulled ^ ^ When the hand 30 moves in the clockwise direction, the force i of the drive head 40 is equal to the force of the pull. However, the thickness of the force segment "b is full meat: negotiable Thick meat · M ^ ^ rj η ^. It is easy to produce cracks or damage, which effectively improves the torque value of the swing head wrench 30. Referring to the tenth figure, when the latching member 60 is subjected to the second section 432 of the external force 40, the card fin is moved from the moon to the driving head 431, and the user can adjust the driving teeth to leave the teeth of the driving head 40. In the eleventh figure, due to the relative pivotal displacement of the card manufacturing plant M with each handle 0. The f 63 series with tooth roots higher than the left and right two end faces 6 hands 4 is more convex, and the tooth 6 is the member 6. The stop limit is limited, but the virtual grip 65, == 40 will not be subject to the latch. This makes the swing head wrench more suitable; narrow 20 =: side 9〇.

Description of the invention (6) The root height of the tooth 63 will not be dragged by the left and right of the latching member 60, which greatly improves the operation of the wrench. You can 1. The "the first section of the living part of the present invention is provided with a window with a toothed circular solitary surface not less than the tooth, and the circular arc surface not less than the thickness of the tooth is L1 (L1 > L). When the thick meat wall can withstand a large increase in the swing head wrench 2 · The "live tooth system of the present invention is more convex, and will not be swung by the left and right pivots of the latch, which increases the swing head width The operation is based on the observation that the positive or negative provisions of the law of the invention of the same or similar inventions have the positive and negative effects described above, only the replacement of the implementation of the invention, or the application according to the invention is still covered by the invention patent. The performance of the left and right end stop wrenches can be summarized as the first and the root of the swing head. The tooth stop limit wrench of the swing head teeth that can withstand the force of the wrench can perform. Mingji has domestic requirements. This is the scope of the present invention. Please cover the patent. The right two end faces 64, 65, so the drive head 40 is aligned, and it can generate a single side 90 with the handle 50. It can be more suitable for operation in a narrow space. The wrench of the present invention changes the second section to the third section and the third power is changed to a higher position when the torque is not easy to torque. It is more suitable to have the following good structure. The round swing head spanner of the arc segment produces cracks. Good structure. The advantages of the left and right sides can be combined with the grip in a small space. The circular solitary surface of the drive head is a full arc surface and a pin hole. If it is stressed or damaged, there is an end face of the latching member, so the drive produces a hinge for operation within 90 sides of the single side, and the side of the thick side effect moves the head. The value is used in large industries; and Seeing foreign publications or public use, they have already met the requirements of patents, and should be granted patents for inventions. It is only the preferred embodiment of the present invention. It should not be compared with changes and modifications made by reason of changes in numerical values or the scope of equivalent elements. White noodle
