At this time, the top plate 3 is lifted upwards. When the driving motor 27 drives the driving screw 25 to rotate in the reverse direction, the front coupling 23 and the rear coupling 24 move outwards, and at this time, the top plate 3 descends.

[0022] In addition, in this device, a handle can also be provided at the end of the driving screw 25. In the case of no power supply, the handle can be manually operated and rotated. Through actual verification, a handle with a length of 40 cm can easily rotate the driving screw 25.
