During the downward movement of the pin row body 2, the pin row body 2 contacts the push plate 17, so that the telescopic rod 20 and the spring 21 are compressed, and the card frame 4 contacts the card block 13 and expands outward. The clamping frame 4 is stretched until the clamping block 13 is engaged with the clamping block 13, so that the mother body 1 and the pin body 2 are tightly connected and do not fall off, and the connection is more stable. When the pin body 2 needs to be removed, the paddle plates 10 on both sides are pressed downward, and the paddle plates 10 drive the rotating block 11 to rotate. The torsion spring 12 stores force, and the rotating block 11 rotates and pushes the clamping frame 4 to release the engagement between the clamping frame 4 and the clamping block 13. At this time, the telescopic rod 20 and the spring 21 rebound and push the push plate 17 to move upward, so that the push plate 17 pushes the pin body 2 to move upward, thereby releasing the connection between the mother body 1 and the pin body 2, and releasing the downward pressure on the paddle plate 10. The torsion spring 12 no longer stores force, thereby driving the connecting rod 9 and the rotating block 11 to rotate back to their original positions.
