The return spring 14 is connected to the striking rod 13 and the second connecting ring 12 through a spring seat. The connecting plate 15 is connected to the striking rod 13. When the protrusion 16 contacts the connecting plate 15, the connecting plate 15 will move the striking rod 13 horizontally away from the protrusion 16, and the return spring 14 will be stretched. When the protrusion 16 and the connecting plate 15 are disconnected, the return spring 14 will move the striking rod 13 back to its original position. At this time, the striking rod 13 will collide with the loading frame 1.
