Specifically, when the carton body moves to contact with a rotating box, a motor drives the rotating box, a clamping plate, and the carton body to flip. When the rotating box rotates, after the movable member separates from the semicircular block, the movable rod and the clamping plate are moved under the action of a third spring to achieve a clamping effect on the carton body. After the carton body flips 180°, the movable member cooperates with the semicircular block to automatically release the lock.
