and fifthly, opening the box door (17), then working through a servo motor (18), driving a lead screw (19) to rotate clockwise in the threaded hole (22), so that a push plate (20) can be driven to move forward in the collecting box (8), and the metal terminal in the collecting box (8) can be pushed out from the rectangular notch.
