Description

Torsion structure

The present invention is related to a torsion structure, in particular, in a torsion structure, the first positioning member has a slightly movable space in the first container, and the axis of the first positioning member can be automatically connected to the first container. The axis of the groove and the axis of the fixed seat group are aligned, and the axis of the adjustment piece can be automatically aligned.

According to my previous knowledge, the conventional torque structure is also a patent case assigned by us. For example, the Taiwan patent application number: 101206451, certificate number: M434652, patent name: torque wrench, the structure of the patent case is: a kind of torque The wrench includes: a hollow main rod body 10, which includes a first end 11 and a second end 12; a tool piece 20, which is inserted through the first end 11 of the main rod body 10; An adjusting screw 30, the adjusting screw 30 includes a top end 31 that can be screwed on the second end 12 of the main rod body 10, and a driving end 32; a torsion adjusting elastic member 40, which is attached to the main rod Inside the body 10 and abuts against the top end 31 of the adjusting screw 30; a clutch assembly 50, which is arranged between the torsion adjusting elastic 40 and the tool 20, and can be used for clutch action; and an adjusting handle 60. A shaft hole 61 penetrates therethrough for the drive end 32 of the adjusting screw 30 to be accommodated. The inner wall surface of the shaft hole 61 protrudes with a convex ring 62; the drive end 32 is sequentially provided with a first screw member 63. A positioning piece 64 and a second screw 65, and the first screw 63 and the positioning piece 64 are respectively arranged on both sides of the convex ring 62; wherein, the driving end 32 is concave parallel to its axial direction. A groove 321 is provided, and the positioning piece 64 is provided with a positioning block 641 that can be fitted into the groove 321; thereby, the The first screw 63, the positioning piece 64, and the second screw 65 can control the rotation or limit between the adjusting screw 30 and the adjusting handle 60.

But the shortcomings of this conventional torque wrench are:

1. As shown in the second figure of the bulletin, the multiple anti-slip grooves 661 and the shaft hole 61 are tightly fitted, so that the first positioning member 66 is tightly fitted in the shaft hole 61, The first positioning member 66 needs to be fixed in the shaft hole 61 by pressing by a machine. After the machine is pressed down for a period of time, there will be deviations. If the shaft center pressed by the machine and the shaft When the axis of the hole 61 is deviated, the axis of the first positioning member 66 will not be aligned with the axis of the shaft hole 61, and the axis of the first positioning member 66 cannot be aligned with the screw hole block. The axis of the adjusting screw 30 is relatively positive. The adjusting screw 30 should be assembled at the first positioning member 66 and the screw hole block 33. The axis of the adjusting screw 30 will be offset. When the adjusting handle 60 drives the adjustment When the screw 30 is screwed and displaced at the screw hole block 33, the shaft center between the first positioning member 66 and the screw hole block 33 will be misaligned, and the adjustment screw 30 will cause unsmooth rotation.

2. The shaft center of the adjusting screw 30, the shaft center of the screw hole block 33, the shaft center of the shaft hole 61 and the shaft center of the first positioning member 66, the shaft centers of the four components must be aligned, the first It is not an optimal structure for the positioning member 66 to be tightly fitted in the shaft hole 61. If the shaft centers of the four components are processed with deviations, the shaft centers will not be aligned.

3. The first positioning member 66 needs to be pressed by a machine, which increases machine cost.

In view of the above-mentioned shortcomings of the conventional structure, the present inventor has finally produced a product with a torsion structure that can solve the drawbacks of the conventional structure through years of experience in manufacturing, production and design in related industries.

The problem to be solved by the present invention: In conventional torque wrenches, the axis of the adjusting screw may be misaligned, and the adjusting screw will cause the loss of unsmooth rotation.
