[0032] It should be noted that the rotation limit structure 6 includes a rotating rod 61, two first bevel gears 62, two keys 63, a second bevel gear 64, a screw rod 65, a chuck 66 and a card slot 67. The rotating rod 61 is located inside the support column 2, and both ends of the rotating rod 61 penetrate to the outside of the support column 2 and are respectively used in cooperation with the two keys 63.

[0036] Working principle: When clamping, the user connects the lifting and clamping structure 5 to the lifting rope through the hanging post 4, and then the user changes the direction of the clamping structure 5 according to the shape of the clamped item. The user inserts the connecting rod 632 of the key 63 into the inside of the connecting slot 633, and then rotates the handle 631. The handle 631 drives the rotating rod 61 through the connecting rod 632 and the connecting slot 633. The rotation of the rotating rod 61 drives a bevel gear 62, the rotation of the bevel gear 62 drives the second bevel gear 64 to rotate, the rotation of the second bevel gear 64 drives the screw rod 65 to rotate, and the screw rod 65 drives the chuck 66 to move downward. When the chuck 66 disengages from the clamping slot 67, the user rotates the support column 2, and the support column 2 drives the limit block 8 and the clamping structure 5 to rotate. The limit block 8 rotates along the track of the limit slot. When the appropriate angle is reached, the user reverses the clamping rod to make the chuck 66 re-embed into the inside of the clamping slot 67 to complete the fixation. Then the user rotates the rotating block 52, the rotation of the rotating block 52 drives the bidirectional screw rod 51, the rotation of the bidirectional screw rod 51 drives the two moving blocks 53 to move, and the movement of the moving blocks 53 drives the clamping blocks 54 to move. When the clamping blocks 54 clamp and fix the item, the user stops rotating. After that, the crane drives the item to move through the lifting and clamping structure 5 to complete the operation.
