[0022] By pulling the connecting rod 7, the connecting rod 7 pulls the pressure plate 12 upward through the pull plate 11 and the pull rod 9, and pulls the positioning rod out of the positioning socket 102, the restriction of the second rotating seat 501 can be cancelled, and then the sliding seat 5 is directly pushed to slide on the connecting plate 1, and the second support plate 3 is supported by the support rod 6, so that the angle of the second support plate 3 changes.

[0023] Furthermore, a wear-resistant pad 401 is disposed on the surface of the buffer pad 4 , and the wear-resistant pad 401 can increase the service life of the buffer pad 4 and prevent the buffer pad 4 from being worn.

[0024] Furthermore, a reinforcing rod 601 is provided on the support rod 6, and the reinforcing rod 601 is used to connect the support rod 6 on each second support plate 3 to improve the supporting effect.
