The hooks 3 are positioned in the two outer chain plates 12 or in the two inner chain plates 11. The pin shaft 2 simultaneously penetrates through the two inner chain plates 11 and the two outer chain plates 12.

Preferably, the hook 3 is made of an elastic plate, specifically, a thin-wall plate made of an iron material or plastic. When the hook 31 is pushed out to the outside of the chain link 1, the hook 31 can automatically rebound into the chain link 1 by the force of the elastic deformation of the hook, so as to achieve the purpose of hiding. The upper end of the hook 3 is fixedly connected to the inner wall of the chain link 1, and a gap is formed between the two sides of the lower section of the hook 3 and the side wall of the chain link 1. Specifically, the upper section of the hook 3 may be welded, or as shown in fig. 5, the two sides of the upper end of the hook 3 are extended outward to form connecting plates 32 with a polygonal structure, the connecting plates 32 penetrate through the side walls of the chain links 1, the connecting plates 32 with a polygonal structure are used to prevent the hook 3 from rotating, and the hook 31 is only restored by the elasticity of the hook 3. Gaps are reserved between the two sides of the lower section of the hook 3 and the side wall of the chain link 1.

Preferably, as shown in fig. 3 and 4, a round rod 13 is disposed inside the chain link 1, the upper end of the hook 3 is rotatably connected to the round rod 13, the round rod 13 is sleeved with a torsion spring 4, and an elastic force generated by the torsion spring 4 is used for enabling the hook 3 to be located inside the chain link 1. As shown in fig. 3, torsion springs 4 may be provided on both sides of the hook 3, or as shown in fig. 4, a torsion spring 4 may be provided on one side of the hook 3. Usually such torsion springs 4 have an extended spring rod at both ends to achieve a contact connection.
