[0045] The number and position of the hooks 6 and the supporting rods 7 can be adjusted according to the size of the workpiece; when the number of the supporting rods 7 needs to be reduced, the double-head motor 11 is started to make the two screw rods 12 rotate and drive the threaded sleeve 13 to move close to the double-head motor 11, then the sliding strip 15 on the outer wall of the threaded sleeve 13 moves in the inner wall of the sliding rail 14, and the lifting plate 10 moves close to the double-head motor 11, driving the positioning column 9 away from the supporting rod 7, until the positioning column 9 is separated from the positioning hole 8, then the supporting rods 7 at the upper and lower ends of the hollow column 4 can be removed as needed; after the supporting rods 7 are removed, the elastic force of the spring 19 makes the slide rod 17 move in the polygonal column 16, pushing the connecting piece 20 away from the polygonal column 16, and the baffle 18 moves into the insertion hole 5 to shield the insertion hole 5; after the supporting rods 7 are removed, the lifting plate 10 is returned to the original position, and the positioning column 9 is inserted into the positioning hole 8 left in the supporting rod 7, and the positioning column 9 without corresponding supporting rod 7 is inserted into the avoiding slot 21 in the connecting piece 20.

[0046] When the support rod 7 needs to be added, the lifting plate 10 is moved away from the direction of the jack 5, and the end of the support rod 7 with the positioning hole 8 is inserted into the jack 5, then the support rod 7 extrudes the baffle 18, the connecting piece 20 moves to the side close to the multi-edge column 16, the slide rod 17 moves in the multi-edge column 16, the spring 19 is extruded, and the baffle 18 cancels the shielding of the jack 5; then the lifting plate 10 is driven to move to the direction close to the jack 5, and the positioning column 9 is inserted into the positioning hole 8 of the support rod 7, so that the positioning of the support rod 7 is completed.
