The oil chamber 110 is slidably connected to the support rod 112, and the bottom end of the support rod 112 seals the oil chamber 110 through a sealing gasket 111. A top block 114 is provided at the top of the support rod 112, and a spring 113 is provided at the bottom end of the top block 114. A supporting foot 17 is provided at the bottom end of the base 1. Each sliding connection mode relies on the sliding connection and cooperation between the protrusion and the slot body, that is, the protrusion slides in the slot body. The bottom end of the support platform 13 is slidably matched with the guide rail 11 through the guide rail seat 12 .

[0025] Furthermore, the bottom cover 18 is fixed to the base 1 by bolts 181 , and the protection assembly is arranged at the side end of the guide rail 11 .
