[0025] Through the above-mentioned structural design, the universal wheel 10 facilitates the elevator to move to the target position. When the elevator reaches the target position for use, the hydraulic cylinder 22 is started. When the hydraulic cylinder 22 receives high-pressure hydraulic oil, the piston reciprocates in the cylinder body, thereby pushing the connecting block 220 to move. The movement of the connecting block 220 facilitates the use of the slide rod 221 to drive the movable block 222 to move, which will facilitate the movable block 222 to drive the scissors frame 23 to work. The scissors frame 23 will drive the lifting platform 12 to rise or fall, thereby facilitating the adjustment of the height of the lifting platform 12.

When the lift reaches the target position, the hydraulic cylinder 22 is started. When the hydraulic cylinder 22 receives high-pressure hydraulic oil, the piston reciprocates in the cylinder body, thereby pushing the connecting block 220 to move. The movement of the connecting block 220 facilitates the use of the slide bar 221 to drive the movable block 222 to move, which will facilitate the movable block 222 to drive the scissor frame 23 to work. The scissor frame 23 will drive the lifting platform 12 to rise or fall, thereby facilitating the adjustment of the height of the lifting platform 12. After the lifting platform 12 is adjusted, when it is raised to the target position, the lifting platform 12 on the lifting platform 12 When the staff needs to use the tools they have forgotten to bring, they start the motor 31, which will drive the winding roller 32 to rotate.
