Description

Torsion structure

The present invention is related to a torsion structure, especially to a torsion structure, when the second adjusting member of the locking group is screwed from the locked position to the unlocked position, the second elastic member is resilient against the first An abutting edge makes the third locking part slightly shift towards the opposite direction of the opening of the accommodating groove, and the second elastic part has the function of making the third locking part escape from the first accommodating groove smoothly.

According to our previous knowledge, the commonly used torsion structure is also the patent case applied by the applicant, such as Taiwan patent application number: 108131052, Taiwan certificate number: I697388, patent name: torsion structure.

But the lack of this customary torsion structure is:

The third elastic member 77 bounces between the positioning seat 60 and the second locking member 74, and when the second adjusting member 76 is rotated to move the locking group 70 to the unlocked position, the fourth screwing Part 761 is screwed in the third threaded part 752 to the opposite direction of the opening of the accommodation groove 11. After the third locking part 73 is not restricted by the fourth locking part 74, the third locking part 73 is It will be naturally displaced, but the design of natural displacement means that there is a chance that one end of the third locking member 73 may still be partially locked in the first cavity 723, and the first body 10 and the positioning seat 60 may still be affected by the first The second locking member 72 and the third locking member 73 are restricted from rotating, so that the first body 10 and the second body 20 cannot rotate relative to each other to adjust the torque value.

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, after the third locking member is not restricted by the fourth locking member, the third locking member will naturally shift, but the design of natural displacement has the possibility that one end of the third locking member may still be partially stuck in the first slot. In the torsion structure of the present invention, when the second adjusting member is screw-shifted from the locked position to the unlocked position, the second elastic member elastically pushes against the first abutting edge, so that the third locking member is moved slightly When the opening of the accommodating groove is displaced in the opposite direction, the second elastic member has the function of enabling the third locking member to escape from the first accommodating groove smoothly.

A torsion structure, which includes: a first main body with a receiving groove; a second main body; a first elastic member; a fixed base set fixed in the second main body; a first adjustment member system Screwed with the fixed seat group, one end of the first adjustment member is provided with a first head; a positioning seat is provided with a plurality of second through-slots; a locking group is connected with the first body, the fixed seat group, The first adjustment member and the positioning seat are assembled together, and the locking group is displaced with the first body. The locking group includes a plurality of first locking members, a second locking member, a plurality of third locking members, a second The elastic part, a fourth locking part, a combining part, a second adjusting part and a third elastic part.

The second elastic piece is provided, and when the second adjustment piece of the locking group is screwed from the locked position to the unlocked position, the second elastic piece is an elastic top Arresting against the first abutting edge and the positioning seat, the third locking member is slightly displaced to the opposite direction of the opening of the accommodating groove, and the second elastic member has a function so that the third locking member can escape from the first locking member smoothly. The effect of a container. The third elastic part is provided, and the third elastic part resists the positioning seat and the second locking part by elastic force, and the third elastic part also has the function of enabling the third locking part to escape from the first groove more smoothly. The effect.

In order to make the committee members and those skilled in this art fully understand the effect of the present invention, the structure and composition of the present invention will be described below in conjunction with the drawings and figure numbers, but the following descriptions are only used to explain the implementation of the present invention For example, it is not intended to limit the present invention in any form, so any modifications and changes made under the spirit of the present invention should still fall within the protection scope of the present invention.
