The two ends of the reset spring a12 are respectively fixedly connected to the inner ends of the two groups of blocks 13. The outer walls of the two groups of blocks 13 are set as inclined surfaces at the bottom. In the process of inserting the rectangular block a8 into the rectangular groove 9, the inner wall of the rectangular groove 9 squeezes the inclined surface of the block 13 to squeeze the reset spring a12.

The inner wall of the base 3 is provided with a card slot 14, and the outer wall of the card block 13 is engaged with the inner wall of the card slot 14. After the rectangular block a8 is fully inserted, the card block 13 is engaged with the card slot 14 under the action of the reset spring a12.
