[0034] Reference Figure 2 The clamping assembly 4 comprises a mounting portion 5, a mounting plate 6, a positioning assembly 7 and two clamping portions 8, the clamping portions 8 and the mounting portion 5 are connected with the mounting plate 6, and the positioning assembly 7 is used for fixing the clamping portions 8 and the mounting plate 6; the mounting portion 5 is provided with a plug-in groove 51, the plug-in groove 51 is sleeved on the outer wall of the second frame body 22; the inner wall of the plug-in groove 51 is provided with an anti-disengagement block 52, the outer wall of the second frame body 22 is provided with an anti-disengagement groove 23 for sliding of the anti-disengagement block 52, the extension direction of the anti-disengagement groove 23 is the same as the extension direction of the second frame body 22, and both ends of the anti-disengagement groove 23 are respectively penetrated through both ends of the second frame body 22.

[0035] The cooperation of the anti-disengagement block 52 and the anti-disengagement groove 23 can avoid the situation that the plug-in groove 51 of the mounting portion 5 is disengaged from the outer wall of the second frame body 22, and by penetrating both ends of the anti-disengagement groove 23 through both ends of the second frame body 22, the mounting portion 5 can be taken out of the second frame body 22, so that the number of the clamping assemblies 4 hung by the lifting frame 2 can be changed, and the spacing between two adjacent clamping assemblies 4 can be changed according to the size of the workpiece.

[0036] Reference Figure 2The mounting portion 5 is provided with a threaded groove 53 in communication with the plug groove 51, a bolt 54 is screwed in the threaded groove 53, and the end of the bolt 54 is used to abut against the outer wall of the second frame body 22. By abutting the end of the bolt 54 against the outer wall of the second frame body 22, the free sliding of the mounting portion 5 on the second frame body 22 can be prevented. In the embodiment, the outer wall of the second frame body 22 is provided with a rubber layer 24, which can increase the friction between the bolt 54 and the second frame body 22, so as to further increase the stability of the mounting portion 5 fixed on the second frame body 22.

[0037] Referring to Figure 3 The mounting portion 5 is provided with two sliding holes 61 penetrating through the upper and lower sides, and one end of each of the two clamping portions 8 is slidably connected with the two sliding holes 61.
