Description

Torsion structure

The present invention is related to a torsion structure, in particular, in a torsion structure, the restriction group can be moved to an unrestricted position or a restriction position on the first body to control the drive group relative to the first body Whether it has the function of torsion tripping, when the restriction group is in the unrestricted position, it has the function of torsion, when the restriction group is in the restricted position, it does not have the function of torsion, the torsion structure can be used as a general connecting rod structure, and the torsion structure has With two different functions, the torsion structure is expandable.

According to my previous knowledge, the conventional torsion structure is also the previous patent application that I applied for. Taiwan patent application number: 108114314, certificate number: I683730, patent name: torsion structure, please refer to the first figure of the bulletin. , Its structure is: a torsion structure, which includes: a first body 10; an elastic member group 20; a driving member 30; a first gear plate 40; a second gear plate 50; a tip body 57; A first ring 58; a second ring 59; at least one restricting member 60; a second body 70 and a screw member 80.

However, the lack of this conventional patent structure lies in:

Drive the first body 10 to rotate, the first body 10 drives the first chainring 40 to rotate, and the first chainring 40 drives the second chainring 50 and the driving member 30 to rotate so as to rotate and fit on the When the rotating torque of the tool part at the second driving part 31 is too large, the first engaging part 42 and the second engaging part 52 will disengage, and the second chainring 50 drives the driving part 30 to The first driving part 12 The elastic element group 20 is compressed by shifting in the direction, and has the function of torsion release. However, the torsion structure is not provided with any control structure to restrict the driving element 30, the first chainring 40 or the second chainring 50 The torsion force jumps and shifts between them, that is, the torsion structure only has the effect of torsion, and the expandability is insufficient.

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 conventional torsion structure only has the function of torsion, and the expandability is insufficient. In the torsion structure of the present invention, the restriction group can be actuated on the first body to an unrestricted position or a restriction position to control whether the driving group has the effect of torsion release relative to the first body. The restriction When the group is in the unrestricted position, the torsion structure has a torsion function. When the restricted group is in the restricted position, the torsion structure does not have the torsion release function. The torsion structure can be operated as a general post structure. The torsion structure has two types With different functions, the torsion structure is expandable.

The present invention relates to a torsion structure, which includes: a first system provided with a first containing groove, a first driving part, at least one first containing hole, at least one first restricting groove and a first restricting part An elastic element set is accommodated in the first container; a drive assembly has the function of torsion release; at least one transmission element is accommodated in the first accommodation hole and the drive assembly, so that the first The main body is assembled with the driving group; a restricting group is arranged with the first body, the elastic element group and the driving group, and the restricting group can be operated on the first body to an unrestricted The control position or a restriction position makes the drive group in a non-restrictive state with respect to the first system and has a torsion release function, or the drive group is in a restricted state with respect to the first system without a torsion release function.

The restriction group can be moved to an unrestricted position or a restricted position on the first body, so that the restriction group does not restrict or restrict the drive group, so that the drive group is in an unrestricted state or relative to the first system. The restriction is used to control whether the driving group has the function of torsion release relative to the first body. When the restriction group is in the non-restriction position, the torsion structure has a torsion function. When the restriction group is in the restriction position, the The driving group is limited by the restriction group. The driving group does not have the function of torsion tripping relative to the first body system. The torsion structure can be operated as a general connecting rod structure. The torsion structure has two different functions. The torsion structure is expandable.
