The middle of the rotating piece 6 is provided with a guide edge 8, the periphery of the guide edge 8 is provided with an annular blocking edge 7, the annular blocking edge 7 is provided with a gap for the limiting rod to pass through, the rotating piece 6 is symmetrically provided with the arc-shaped groove 12 around the guide edge 8, the arc-shaped groove 12 is matched with the limiting column 5, and the rotating piece 6 is rotatably arranged on the limiting column 5 through the arc-shaped groove. The end of the connecting rod 10 is located in the guide edge, the end of the connecting rod 10 is horizontally provided with the limiting rod 9, and the two ends of the limiting rod 9 are in abutment with the guide edge 8. The rotating part 3 is rotatably arranged on the front of the hook body 1, and the blocking piece 11 for driving the rotating piece to rotate is arranged on the rotating part 3. When the rotating part rotates, the blocking piece 11 drives the rotating piece to rotate, the guide edge 8 drives the limiting rod to move up or down closely on the guide edge under the action of the spring when the rotating piece rotates, and then the suction cup is deformed to achieve the purpose of negative pressure adsorption.

[0023] In the embodiment, the rotating part 3 is annular, the outer wall of the rotating part 3 is provided with a stripe or a groove for increasing friction and is rotatably connected with the hook body, the blocking piece 11 is arranged on the lower end surface of the inner wall of the rotating part 3, and the cover plate 4 is arranged on the rotating part.
