The threaded rod 501 and the stabilizing rod 6 are arranged parallel to each other. By rotating the rotating tube 502, the rotating tube 502 uses the threaded rod 501 and the stabilizing rod 6 to drive the adjusting rod 4 away from or towards the mounting frame 2. In this way, the first tilting rod 302 and the second tilting rod 303 work together to drive the stop rod 301 away from or towards the mounting frame 2, and the stop rod 301 can be unfolded and retracted.
