First, the target position to be reached by the positioning mechanism 70 is set through the touch display screen 50, the processor controls the angle and direction of the servo motor to be rotated according to the target position, and sends a control signal to start the operation of the servo motor. The output end of the servo motor drives the lead screw to rotate, the lead screw is in transmission connection with the ball nut, the ball nut moves along the axial direction of the lead screw with the rotation of the lead screw, thereby driving the walking seat 40 connected with the ball nut to slide along the sliding rail.
