In addition, the support piece 5 is fixedly inserted into the slot 302 through the inserting lug 5011, a second fixing hole 5012 matched with the first fixing hole 3021 is formed in the surface of the side wall of the inserting lug 5011, the first fixing hole 3021 and the second fixing hole 5012 are fixedly connected through bolts, the support piece 5 is fixedly mounted on the support leg 301, and meanwhile, the support piece is convenient to detach due to the bolt fixing mode.

In addition, second spring 4013 one end and activity chamber 4012 inner wall upper surface fixed connection, the second spring 4013 other end and spacing lid 4021 upper surface fixed connection fix the second spring 4013 in activity chamber 4012, and spacing lid 4021 size and activity chamber 4012 aperture looks adaptation, and activity chamber 4012 aperture is greater than dead lever 401 lower surface opening aperture.

Specifically, the positioning block 503 is an L-shaped structure, the upper surface of the positioning block 503 is an arc-shaped curved surface structure, a limiting groove 5032 is formed on the edge of the upper surface of the positioning block 503 close to the edge from the arc-shaped curved surface to the positioning hole 5031, the aperture of the positioning hole 5031 is matched with the aperture of the movable rod 402, the upper wedge 5021 is matched with the lower wedge 403, the expansion amount of the movable rod 402 is matched with the vertical height of the upper surface of the positioning block 503, when the upper wedge 5021 is matched with the lower wedge 403, the bottom of the movable rod 402 is matched with the limiting groove 5032, and when the lower wedge 403 moves downwards, the movable rod 402 moves towards the positioning hole 5031 along the limiting groove 5032.

Further, at least crossbeam 601 is included in bolster 6, crossbeam 601 upper surface center department fixedly connected with buffering post 602, nested connection has third spring 6021 on the buffering post 602, crossbeam 601 lower surface is close to the first buffering leg 603 of left end edge fixedly connected with, crossbeam 601 lower surface is close to right-hand member second buffering leg 604, the equal fixed mounting in first buffering leg 603 and second buffering leg 604 bottom has blotter 6031, play the effect of shock attenuation buffering to supporting leg 301 through bolster 6, and first buffering leg 603 and second buffering leg 604 are highly the same, in uncompressed state, first buffering leg 603 and second buffering leg 604 are located the below of supporting leg 301, guarantee first buffering leg 603 and second buffering leg 604 can play the cushioning effect.

The buffer member 6 is fixedly inserted into the buffer groove 5041 through the buffer column 602, the beam 601 is clamped and fixed in the rectangular through hole 504, the third spring 6021 is arranged in the rectangular through hole 504, and the damping and buffering effects are achieved through the arranged third spring 6021.

Still further, the height of the rectangular through hole 504 is matched with the height of the buffer groove 5041, the length of the buffer column 602 is matched with the height of the buffer groove 5041, the expansion amount of the third spring 6021 is matched with the length of the first buffer leg 603, the length of the first buffer leg 603 is the same as the length of the second buffer leg 604, it is guaranteed that the beam 601 can normally move in the rectangular through hole 504, and the buffer column 602 can normally move in the buffer groove 5041.
