When the height of the operating table 1 needs to be adjusted, the second driving motor is turned on, and the second driving motor drives a group of third gears 207 to rotate. Since the third gears 207 are meshed with each other, the two groups of third gears 207 can be driven to rotate. Under the action of the rotation of the third gear 207, the rack plate 206 moves, thereby driving the lifting plate 205 to synchronously displace, so that the height of the operating table 1 changes.
