[0039] Secondly, when the supporting area of ​​the lifting mechanism 2 needs to be adjusted, first pull the extrusion plate 213 to separate the pin shaft 214 from the slot, then turn the rocker 204 to drive the winding roller 203 to release the connecting rope 205, and then start the hydraulic rod 109 to extend it out of the piston end, and the distance between the vertical rods 101 increases. When the connecting rope 205 is taut, release the extrusion plate 213, and the spring 208 drives the pin shaft 214 to re-engage with the slot, and stop the hydraulic rod 109 at the same time.
