The second abutting part and the first abutting part are arranged between the first adjusting part to be locked together, and the second locking part, the first locking part and the first adjusting part have a certain locking structure, It has a positive locking structure.

According to our previous knowledge, the conventional torque wrench structure, such as Taiwan patent application number: 096217159, certificate number: M333999, patent name: adjustable torque wrench structure (1), the structure of the patent case is: an adjustable torque wrench The structure (1) includes: a main rod 10 and an elastic body 14. An accommodating space 11 is formed inside the main rod 10, and a stop 16 is provided at the end of the accommodating space 11 so that the elastic body 14 is accommodated in the accommodating space 11 The space 11 is relatively stopped at the stop 16, and the outer edge of one end of the main rod 10 is radially provided with a positioning pin 12; a guide 20 and a guide block 25, the guide 20 is accommodated in the main In the accommodating space 11 of the rod 10, one end of the guide member 20 is formed with a top end 22 for stopping the elastic body 14, and the guide member 20 contains a guide groove 21 for accommodating a guide block 25, the radial position of the outer edge of the guide block 25 is provided with a positioning hole 27 corresponding to the positioning pin 12 of the main rod 10, so that the positioning pin 12 of the main rod 10 is inserted into the positioning hole 27 of the guide block 25 to achieve mutual positioning , And the center of the guide block 25 is provided with an internal thread section 26, the other end of the guide member 20 is provided with a coupling hole 23, and the other end of the guide member 20 is provided with a plurality of fixing grooves 24; a rod sleeve 30 , Linkage 33 and adjustment part 34, one end of the rod sleeve 30 is rotated Covering the main pole 10, the other end is relatively fixed with a linkage member 33, the linkage member 33 is provided with a coupling portion 362, and the coupling portion 362 is provided with a fixed adjustment portion 34, the adjustment portion 34 is formed to be screwed on The guide block 25 has an outer threaded section 35. A connecting section 36 is formed adjacent to the outer threaded section 35. The connecting section 36 provides a connecting hole 23 pivoted to the guide member 20, and the other end of the connecting member 33 is provided with a pin hole. 38, and the other end of the adjusting portion 34 is provided with a limiting portion 37, the outer edge of the limiting portion 37 is provided with an external thread; a limiting device 50, which includes a knob 51 and a fixing pin 54, wherein the knob 51 is provided with a limiting Hole 52, the limiting hole 52 is formed with an internal thread that is relatively screwed to the limiting portion 37 of the linking member 33, and the fixing pin 54 is corresponding to the pin hole 38 of the linking member 33, and the fixing pin 54 is opposite to Stopped at the knob 51, the front end of the fixed pin 54 is protrudingly set in the fixed groove 24 of the guide member 20, so that the rod sleeve 30 is locked and cannot be given a rotating function state.

But the shortcomings of this conventional torsion structure are:

1. The gasket 53 is pressed against the two fixing pins 54 and the two fixing pins 54 are then positioned at the fixing groove 24. After being in the locked state, a small number of people will test whether it is really in the locked state, that is, The rod sleeve 30 is rotated, so that the washer 53, the two fixed pins 54 and the fixed groove 24 are subjected to rotational force, and frictional force will be generated at the washer 53 and the fixed pin 54. For a long time, the washer 53 It will wear out and cause ring-shaped dents.

2. To lock the adjustment function of the rod sleeve 30, the knob 51 needs to be turned first, so that the limit hole 52 spirally advances relative to the limit portion 37, so that the spacer 53 passing through the adjustment portion 34 The two fixing pins 54 are forced to move forward, so that the two fixing pins 54 are embedded in the fixing groove 24. The guide member 20 is limited in the radial direction by the guide block 25 and cannot rotate, and restricts the linkage members 33, The rod sleeve 30 cannot be rotated, but the guide member 20 needs to be milled with the guide groove 21 and drilled with a plurality of fixed grooves 24, and the guide member 20 has a relatively high 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.

In the conventional torque wrench structure, the washer and the fixed tip will generate frictional force, and the washer will wear over a long period of time to cause ring-shaped dents. In the torsion structure of the present invention, the second locking member and the first The first locking part is provided between a locking part to be locked together, and the second resisting part and the first resisting part are provided between the first locking part and the first adjusting part to be locked together , The second locking member, the first locking member and the first adjusting member have a positive locking structure.
