The moving plate 604 is arranged on the outer wall of one side of the connecting plate 602. The blade 605 is arranged on the outer wall of one side of the moving plate 604. The guide port 603 is arranged on the inner wall of one side of the connecting plate 602 and corresponds to the blade 605. The second spring 606 is welded to the outer wall of the connecting plate 602 and the bottom end of the second spring 606 is welded to the outer wall of the connecting plate 602. The rotating wheel 609 is arranged on the top end of the outer wall of the moving plate 604.
