The rotation member 20 may have a rectangular parallelepiped structure, and the rotation member 20 has opposite upper and lower surfaces and a through hole 21 communicating the upper and lower surfaces, and in the present embodiment, the through hole 21 is provided at a middle position of the rotation member 20 in a length direction. The connecting rod 10 is vertically movably inserted through the through hole 21 of the rotating member 20, and in the present embodiment, a portion between the mounting portion 12 and the first stopper portion 11 of the connecting rod 10 is vertically movably inserted through the through hole 21 of the rotating member 20, and the first stopper portion 11 is located at one side of the lower surface of the rotating member 20.

The supporting arm 30 is connected to the rotating member 20, and the hanger preferably includes two supporting arms 30, the two supporting arms 30 are respectively symmetrically located at two sides of the through hole 21 of the rotating member 20, in this embodiment, the through hole 21 is located at a middle position of the rotating member 20 along the length direction, and the two supporting arms 30 are respectively located at two ends of the rotating member 20 along the length direction. The support arm 30 has opposite upper and lower ends, and preferably, the upper end of the support arm 30 is connected to the rotary member 20 and the lower end of the support arm 30 has a hook structure.

The hook 40 may be used to hook a workpiece, and a surface treatment operation, such as painting, may be performed on the workpiece while the hook 40 hooks the workpiece. The hook 40 includes a cross bar 41 and a hooking portion 42 for hooking the workpiece, the cross bar 41 being removably hooked at the lower ends of the two support arms 30, the hooking portion 42 connecting the cross bar 41. In this embodiment, under the action of gravity, the cross bar 41 of the hook 40 is hooked on the hook structure at the lower end of the two support arms 30, under the action of external force, the hook 40 moves upwards, and the cross bar 41 of the hook 40 can be separated from the hook structure at the lower end of the two support arms 30, so that the hooks 40 with different structures can be replaced, and the requirements for hooking different workpieces are met.

The lower surface of the rotation member 20 is provided with a second stopper portion 22, and the second stopper portion 22 of the present embodiment is formed around the through hole 21 of the rotation member 20. As shown in fig. 3, when the rotating member 20 moves downward, the first limiting portion 11 and the second limiting portion 22 are engaged, the upper surface of the first limiting portion 11 contacts with the lower surface of the second limiting portion 22 to limit the rotating member 20 from rotating around the connecting rod 10, and when the workpiece on the hook 40 is sprayed, the workpiece does not shake, and a uniform coating can be formed on the surface of the workpiece.
