Description

Torsion structure

The present invention is related to a torsion structure, especially in a torsion structure, when the first supporting surface is assembled in the first surface, the supporting member is less deformed, and the supporting member has the function of supporting strength.

According to what I have previously known, the conventional torque structure is also a patent filed by me. For example, Taiwan Patent Application No.: 107132640, Certificate No.: I661906, Patent Name: Torque Wrench Structure, its structure is: a type of torque wrench structure , Which includes: a first body 10; a second body 20; a first elastic body 40, the first elastic body 40 is fixed on the inner peripheral surface of the second end 14, the first elastic body 40 is an external force and is assembled on the inner peripheral surface of the second end 14. The outer peripheral surface of the first elastic body 40 is the first supporting surface 41, and the first supporting surface 41 is connected to the second end 14 The inner peripheral surface is in a tight-fitting shape, the inner peripheral surface of the first elastic body 40 is the second supporting surface 42, and the first elastic body 40 is a spiral spring structure composed of a plurality of ring bodies, so that the first support The surface 41 and the inner peripheral surface of the second end 14 are in a non-continuous contact shape; an abutting member 50; a driving block 60 and a first pivoting member 71.

But the shortcomings of this conventional torque wrench structure are:

As shown in the third figure of the bulletin, the first elastic body 40 is a helical spring structure composed of a plurality of ring bodies, and the first elastic body 40 is assembled on the inner periphery of the second end 14 by an external force. At the surface, the first elastic body 40 may be applied due to external forces during the assembly process. The first elastic body 40 It will cause squeeze deformation, that is, if the assembly is correct, each of the gaps 43 will have a value in a small range, if the assembly is not correct, each of the gaps 43 will have a value in a larger range, the first elastic body 40 That is, with greater internal stress, the effect of supporting the second end 14 of the first elastic body 40 with greater internal stress is reduced.

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 invention: In the conventional torsion structure, the first elastic body may cause extrusion deformation due to external force during the assembly process. In the torsion structure of the present invention, the first elastic body may cause extrusion deformation. When the supporting surface is assembled in the first surface, the supporting member is less deformed.

Technical means to solve the problem: The present invention relates to a torsion structure, which includes: a first body, the first system is in the shape of a straight rod, and the first system is provided with an accommodating space. The accommodating space is in the shape of a penetrating groove, and the accommodating space is provided with a first surface; a second body, the second system is assembled with the first body, and the second system is partially accommodated in the In the accommodating space, one end of the second body is provided with a driving head; a supporting member, the supporting member is fixedly arranged in the accommodating space, the outside of the supporting member is the first supporting surface, and the inside of the supporting member It is a second supporting surface. The second supporting surface includes a second threaded portion and a second surface. The second threaded portion and the second surface are arranged at intervals so that the second supporting surface is internally Spiral.

Compared with the effect of the prior art: the supporting member is fixed to the body, the supporting member cannot be displaced in the accommodating space and the first surface, and the supporting member has the function of supporting the first body. Has better structural strength. When the first supporting surface is assembled in the first surface, the supporting member is less deformed by external force, and the supporting member has the function of supporting the first body.
