Detailed ways

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the implementations. example. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention.

Please refer to FIG. 1-FIG. 5, the present utility model provides a technical solution: a new type of firmware structure, comprising a connecting rod 1, a limit block 8 is provided at the top of the connecting rod 1, a nut 3 is provided on the top of the limit block 8, and the screw A sliding rod 5 is provided in the middle of the bottom end of the cap 3, a sliding groove 4 is provided at the top of the connecting rod 1, and the sliding rod 5 penetrates the inner wall of the limit block 8 and is located inside the sliding groove 4, and the inner side of the sliding groove 4 is provided with a limiting groove 6. A rubber ring 7 is provided at the bottom end inside the limiting groove 6 .

In order to facilitate the rotation of the nut 3 to drive the connecting rod 1 to rotate, in this embodiment, preferably, a clamping slot 9 is provided on the outer side of the top end of the limit block 8, and a clamping block 10 is provided on the outer side of the bottom end of the nut 3, and the clamping block 10 is located in the clamping slot. 9 inside.
