[0025] The specific implementation of the present invention will be further described in detail below with reference to the accompanying drawings.

[0026] Example:

[0027] Depend on Figures 1 to 3 Provided is an anti-skid chain, comprising a first fixing member 1 and a second fixing member 2, one end of the first fixing member 1 being connected to one end of the second fixing member 2 via an anti-skid assembly, the anti-skid assembly being composed of a plurality of anti-skid connectors 3 which are detachably connected end to end, and the length of the anti-skid assembly can be controlled by setting the number of anti-skid chain connectors, the other end of the first fixing member 1 being connected to the second fixing member 2 via a tensioning belt 4 of adjustable length.

[0028] Specifically, in order to facilitate the connection between the anti-slip connectors 3, one end of the anti-slip connector 3 is provided with one or more first hooks 31, and the other end of the anti-slip connector 3 is installed with a first connection groove 32 corresponding to the position of the first hook 31. The two anti-slip connectors 3 are connected by hooking the first hook 31 into the first connection groove 32.

[0029] It should be noted that the end of the first fixing member 1 or the second fixing member 2 connected to the anti-slip component is respectively provided with a second hook 21 or a second connecting groove 22, the second hook 21 has the same structure as the first hook 31, and the second connecting groove 22 has the same structure as the first connecting groove 32, so that the anti-slip connecting member 3 close to the first fixing member 1 and the second fixing member 2 can be connected to the first fixing member 1 and the second fixing member 2 in the same way.
