The first spring 202 above the buffer base plate 1 buffers the lifting device 12. At the same time, the connecting rod 205 above slides inside the sliding rod 206 to support the bottom of the lifting device 12.

[0032] Multiple sliding grooves 215 are provided on the upper surface of the support plate 216 near both sides. Sliding members 211 are slidably connected inside the sliding grooves 215. A lifting rod 212 is rotatably connected to the upper end of the sliding member 211.
