The adjusting nut 21 is threadedly connected to the threaded rod 14. The position of the movable plate 19 can be adjusted by rotating the adjusting nut 21 using a tool.

[0042] The working principle of the above embodiment is:

[0043] Before use, according to the specific type of product, such as when painting shaft sleeve products, the position of the sliding frame 4 relative to the hanging frame 1 is pre-slid. At this time, the shaft sleeve product is placed on the top of the load-bearing plate 2, and the sliding mounting beam 6 is used to adjust the position of the shaft clamping mechanism, and the shaft clamping mechanism is extended to the inside of the shaft sleeve product. The adjusting nut 21 located on the outside of the shaft sleeve product is rotated by using a tool. The adjusting nut 21 is threadedly engaged with the threaded rod 14 under rotation. At this time, the movable plate 19 rotatably connected to the adjusting nut 21 changes its position relative to the threaded rod 14. At this time, the support rod 20 connected to the movable plate 19 changes its angle relative to the threaded rod 14, and pushes the abutment plate 18 at the other end to gradually move away from the threaded rod 14 and open. Under the rotation connection of the connecting rod 17, the abutment plate 18 is maintained parallel to the position of the threaded rod 14 and abuts against the inner wall of the shaft sleeve. At this time, the loading of the shaft sleeve is completed, and then the locking frame 5 is adjusted so that the sliding frame 4 is locked relative to the hanging frame 1, and the product can be put into the coating line for spraying.
