A secondary hook is fixedly connected to the bottom end of the suspension plate near the edge of the guiding chute. A plurality of fixed rails are fixedly installed on the upper surface of the suspension plate. A movable plate is movably installed inside the fixed rail. A plurality of limiting columns are welded at the bottom end of the movable plate passing through the guiding chute. A sliding mechanism is further provided inside the hollow branch pipe for limiting and fixing the workpiece on the outer surface of the secondary hook.

[0008] Preferably, the sliding mechanism includes a connecting rotating rod. The connecting rotating rod is rotatably installed at the edge of the top end of the movable plate near the hollow branch pipe. A movable rod is movably installed inside the hollow branch pipe. A plurality of fixing grooves are opened on one side of the inner wall of the hollow branch pipe near the suspension plate. A mounting seat is fixedly connected to the outer surface of the movable rod extending to the outside of the fixing groove. The top of one side of the connecting rotating rod is hinged inside the mounting seat.

[0009] Preferably, a spring is installed at the bottom end of the inner wall of the hollow branch pipe, the upper surface of the spring abuts against the lower bottom surface of the movable rod, a thread is opened through the middle of the top end of the inner wall of the hollow branch pipe, and a limiting screw is rotatably installed on the upper surface of the movable rod through a threaded hole.
