[0004] Generally, after a pruning stand is stepped onto a support plate, the motor is started to rotate the threaded rod. Under the action of a limit rod and a slider, the movable plate can be moved vertically along the surface of the threaded rod, driving the support plate to move up. After moving to a suitable position, the motor is turned off, stopped, and then rotated again.
