[0029] The starting cylinder 32 drives the telescopic end to move, so as to drive the lifting plate 34 to move and adjust the position of the lifting plate 34. When the lifting plate 34 moves, it can drive the guide rod 33 to move, guiding the movement of the lifting plate 34 to ensure the stable movement of the lifting plate 34.

[0030] By pushing the winding rod 103 to rotate, the traction wire 104 can be wound to pull the plug plate 105 to move. Under the action of the fixed rod 106, the spring 107 deforms. Eventually, the plug plate 105 disengages from the left side wall of the oil storage box 102, making the diversion hole of the oil storage box 102 in a flowing state. Under the action of the diversion pipe 101, the lubricating oil can be diverted, and then the lubricating oil contacts the telescopic end of the cylinder 32 to lubricate the cylinder 32 and reduce the telescopic resistance of the cylinder 32.
