Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides a technical solution: an expanded casing with an enhanced expansion coefficient, comprising: the expansion sleeve comprises an expansion sleeve 1 and a through hole 2, wherein the through hole 2 is formed in the outer wall of the bottom end of the expansion sleeve 1;

the through hole 2 is movably inserted with a convex block 3, one side of the convex block 3 is fixedly connected with an inclined block 4, two sides of the convex block 3 in the through hole 2 are respectively and fixedly provided with a side rod 5, and one side of the side rod 5 is in butt joint with a sliding mechanism.

The sliding mechanism comprises a sliding block 6 and a sliding groove 7, one side of the sliding block 6 is fixedly connected with the side rod 5, and the sliding block 6 is movably arranged in the sliding groove 7, so that the side rod 5 can be driven to move when the lug 3 moves, and the sliding block 6 can be driven to move in the sliding groove 7 when the side rod 5 moves, so that the lug 3 can not shake randomly when moving;

the sliding groove 7 penetrates through the inner wall of the through hole 2 and is arranged inside the expansion sleeve 1, and the convex block 3 is in sliding connection with the sliding groove 7 through the side rod 5 and the sliding block 6;
