The infrared generator 12 is controlled by the control panel 3 to operate. The infrared generator 12 sends an infrared light beam vertically downward. The infrared light beam is emitted after encountering the ground, and then the reflected infrared light beam is received by the infrared receiver 13. After receiving the infrared receiver 13, it sends an electrical signal to the control panel 3. The control panel 3 obtains the time interval from the emission of the infrared light beam to the reception. The control panel 3 calculates the distance value between the lifting plate 11 and the ground according to the propagation speed of the infrared light beam in the air and the time interval from the emission of the infrared light beam to the reception. Under the upward thrust of the spring 9, the lifting plate 11 is attached to the fixed plate 10. At this time, the distance value between the lifting plate 11 and the ground is the initial value.
