The hooks 5 can be disassembled through the fixing nuts 20, which is convenient for replacing the hooks 5.

[0024] like Figure 3 and Figure 4 As shown, one side of the guide block 8 is fixedly connected to the connecting block 6, one side of the connecting block 6 is fixedly connected to the fixing ring 7, one side of the outer wall of the rotating shaft 9 is rotatably connected to the inner wall of the fixing ring 7, one end of the rotating shaft 9 is fixedly connected to the hexagonal rotating rod 25, the outer wall of the hexagonal rotating rod 25 is slidably connected to the hexagonal connecting ring 24, one side of the hexagonal connecting ring 24 is slidably engaged with one side of the fixing ring 7, by pushing the hexagonal connecting ring 24, when one side of the hexagonal connecting ring 24 is stuck on the inner wall of the fixing ring 7, the hexagonal rotating rod 25 and the connecting block 6 are connected into a whole, thereby fixing the hexagonal rotating rod 25, preventing the hexagonal rotating rod 25 from rotating, and improving the stability of the hook 5.
