[0034] Specifically, the fitting assembly includes two sliding grooves 8, which are respectively opened at the front and rear ends of the outer wall of the support column 5. The front and rear ends of the outer side of the support column 5 are both provided with fitting plates 11. The outer wall of the fitting plate 11 is rotatably connected to two connecting columns 9. The ends of the connecting columns 9 are fixedly connected to fixed ball heads 10, which are slidably connected to the inside of the sliding grooves 8. The outer wall of the connecting column 9 is fixedly connected to a connecting ring 15, which is slidably connected to the outer wall of the support column 5. The fitting plate 11 is designed to be a curved surface.

[0035] Furthermore, the lifting ring 13 is connected to the clamping column 3 through an elastic rope, and the pressure plate 6 and the chassis 4 can slide in the sliding groove 8 of the connecting column 9 through the spring 7 and the telescopic rod 14 according to the size of the workpiece, so that the position of the bonding plate 11 can be controlled, and the clamp is inserted into the interior of the workpiece. The bonding plate 11 and the bonding block 17 fix and clamp the workpiece through the movement of the connecting column 9. The internal support clamping design can ensure uniform coating of the outer surface of the workpiece, and the hanging chain design can improve the working efficiency of the electrophoretic coating line; fixing the connecting ring 15 on the outside of the connecting column 9 can ensure the position of the bonding plate 11 and prevent the connecting column 9 from falling off; designing the shape of the bonding plate 11 as a curved surface can better fit and adsorb with the inner wall of the workpiece, thereby improving the stability of clamping.
