Detailed Description

The structure of the present invention will be further described by way of examples with reference to the accompanying drawings. It is to be understood that this embodiment is illustrative and not restrictive.

A special tool for fastening a belt, please refer to Figs. 1-3, mainly comprising a guide cylinder 2, a fixed hook seat 6, a sliding hook seat 4, a left hook 3, a right hook 5, an end plug 1 and a threaded screw 7.

The structure and the function of each part are respectively as follows:

1. guiding a cylinder: the main part of this design plays the direction supporting role, and its shape is: the side wall is provided with an open cylinder with axial guide grooves 2.1.

2. Sliding the hook seat: the inner cavity of the guide cylinder moves to realize the stress of an acting piece (a fastening belt, the same below); the shape is as follows: the guide block is composed of a cylindrical main body part and a guide block part connected with the outer side of the main body part. The outer diameter of the main body part is matched with the inner cavity of the guide cylinder, and the width of the guide block part is matched with the groove width of the axial guide groove on the guide cylinder.

3. Fixing the hook seat: the movement of the threaded screw is realized by positioning the threaded screw and the right hook, and the threaded screw and the right hook are fixedly arranged at the same guiding end. The shape is as follows: the guide block is composed of a cylindrical main body part and a guide block part connected with the outer side of the main body part. The outer diameter of the main body part is matched with the inner cavity of the guide cylinder, and the width of the guide block part is matched with the groove width of the axial guide groove on the guide cylinder.
