The U-shaped plate 102 is fixedly installed at the center of the top of the base 101. A driving mechanism 2 is arranged between the inner walls of the U-shaped plate 102. The driving mechanism 2 includes a motor 201 and a lead screw 202. A lubricating mechanism 5 is installed on the top of the U-shaped plate 102. The lubricating mechanism 5 includes a fixed column 501, a control valve 502, an oil inlet pipe 503, an oil outlet pipe 504, a sleeve 505 and a sponge layer 506. The fixed column 501 is fixedly installed on the top of the U-shaped plate 102. The control valve 502 is fixedly installed on the upper side wall of the fixed column 501. The oil inlet pipe 503 is connected to the inner cavity of the fixed column 501 through the control valve 502. The upper end of the oil outlet pipe 504 is connected to the inner cavity of the fixed column 501, and the lower end of the oil outlet pipe 504 passes through the U-shaped plate 102 and is connected to the inner wall of the sleeve 505. The sleeve 505 is fixedly installed on the top of the movable block 301. The sponge layer 506 is movably sleeved on the outer surface of the lead screw 202. Start the motor 201 and control its output end to drive the lead screw 202 to rotate counterclockwise. The movable block 301 threadedly sleeved on its outer wall will drive the telescopic rod 304 to move upward. At this time, the lubricating oil in the inner cavity of the fixed column 501 will flow into the inner cavity of the sleeve 505 through the oil outlet pipe 504, and then soak the sponge layer 506 to lubricate the outer surface of the lead screw 202 when the lead screw 202 rotates. The excess lubricating oil will flow along the outer surface of the lead screw 202 through the cylindrical block 403 and the drainage pipe 402 into the oil storage tank 401 to be collected for secondary use. Control the output end of the motor 201 to drive the lead screw 202 to rotate clockwise. The movable block 301 threadedly sleeved on its outer wall will drive the telescopic rod 304 to move downward. At this time, the pressure in the fixed column 501 decreases, and the lubricating oil in the oil storage tank 401 will flow into the fixed column 501 along the oil inlet pipe 503 to replenish the inner cavity of the fixed column 501, so as to repeatedly lubricate the outer surface of the lead screw 202 and extend its service life.
