Torsion structure

The present invention relates to a torsion structure, especially a torsion structure, in which the third threaded part and the first threaded part have a fine-tuning function to fine-tune the position of the first body, and the second threaded part and the first threaded part have a fine-tuning function. The third body, the first threaded part and the second threaded part have a fine-tuning function to fine-tune the position of the adjustment group. There are two fine-tuning locations with their own fine-tuning purposes and each with its own function.

According to our previous knowledge, the commonly used torsion structure is also the patent case applied by the applicant. Taiwan patent case number: 109107365, certificate number: I714469, patent name: torsion structure, the structure of the patent case lies in: a torsion structure , whose lines include:

A first body group 10, the first body group 10 includes a first body 11, a first positioning part 12 and at least one second positioning part 15;

The inside of the first body 11 is provided with a first container 111 , the first container 111 runs through the first body 11 , and the rear end of the first container 111 is provided with at least one first positioning portion 118 . A positioning portion 118 communicates with the first container 111;

The first positioning part 12 is accommodated in the first cavity 111, and the outer peripheral surface of the first positioning part 12 is provided with at least one second positioning part 122, and the second positioning part 122 is connected with the first positioning part. 118 parts are relatively positive;

The second positioning member 15 is assembled on the first positioning portion 118 and the second positioning portion At 122, the first positioning member 12 is assembled in the first cavity 111, and the rotation of the first body 11 drives the rotation of the second positioning member 115 and the first positioning member 12;

A second body 20, the second body 20 is combined with the first body group 10, the second body 20 is partially accommodated in the first container 111, and one end of the second body 20 is provided There is a driving part 21;

A first elastic member 26, the first elastic member 26 is accommodated in the second body 20, one end of the first elastic member 26 bounces against the second body 20, the first elastic member 26 is used to The second body 20 has the function of torsion escape;

A fixed seat group 40, the fixed seat group 40 is fixed in the second body 20, the fixed seat group 40 is located near the opening of the second body 20, the fixed seat group 40 is connected with the driving part 21 away from each other;

An adjustment member 50, the adjustment member 50 is screwed and displaced in the second body 20 to adjust the compression degree of the first elastic member 26 to adjust the torque value, the other end of the first elastic member 26 is directly or indirectly elastic Arresting on the adjustment piece 50, the first elastic piece 26 directly or indirectly bounces between the second body 20 and the adjustment piece 50, so that the second body 20 has the effect of torsion jumping, and the adjustment piece The end of 50 is assembled with the first positioning member 12 , so that the adjusting member 50 is assembled with the first body set 10 .

But the deficiencies of this customary torsion structure are:

The first threaded part 13 is in the shape of a hexagon, and the fitting part 123 is in the shape of twelve grooves. The first threaded part 13 is fitted with the fitting part 123, so that the first The 13 system drives the adjustment member 50 to rotate, which is the principle of torque adjustment, but when the torque wrench structure leaves the factory, there are two adjustments to be made, namely, alignment on the scale and the return of the first elastic member 26 to the original position. value, in the factory adjustment of the torque, it is necessary to align the position and return the torque to the initial value, and the two places must be aligned with each other. Only the first positioning part 12 is used to drive the adjustment part 51 to rotate so that the first elastic part 26 returns to the initial value. , but it is more difficult to align the scale. There is only one adjustment structure for the alignment of the scale and the return of the torque to the initial value. There is a dilemma in the adjustment.

In view of the lack of the above-mentioned conventional structure, the inventor has been engaged in the manufacture, production and design of related industries for many years, and finally a product with a torsion structure that can solve the conventional disadvantages comes out.

In the conventional torsion structure, only using the first positioning member to drive the adjustment member to rotate is only convenient to return the first elastic member to the initial value, but it is difficult to align the scale, and to make the alignment of the scale and the torque return to the original There is only one adjustment structure for the value, and there is a dilemma in the adjustment system. In the torsion structure of the present invention, there is a fine-tuning function between the third threaded portion and the first threaded portion to fine-tune the position of the first body, and the second threaded portion is connected to the third body, the first threaded portion There is a fine-tuning function between the fitting and the second screw fitting to fine-tune the position of the adjustment group. The third body group has two fine-tuning functions, and the two fine-tuning systems have their own fine-tuning purposes and have their own functions.
