The plug-in block 2 is inserted into the fixing plate 3, and the plug-in block 2 squeezes the locking block 31 during the insertion process. After the locking block 31 is squeezed, the locking block 31 is supported by the pull plate 33 with the assistance of the telescopic assembly to compress the spring 32, and then the plug-in block 2 continues to be inserted. When the insertion of the plug-in block 2 is completed, the spring 32 pushes the locking block 31 in the reverse direction to pop out, so that the locking block 31 is inserted into the slot 21 to fix the plug-in block 2, which is convenient for locking the plug-in block 2.

When the insertion of the plug 2 is completed, the spring 32 pushes the card block 31 in the opposite direction to pop out, so that The card block 31 is inserted into the card slot 21 to fix the insertion block 2. When it needs to be removed later, the turntable 62 is turned to allow the turntable 62 to drive the rotating rod 61 and the gear 6 to rotate. After the gear 6 rotates, it engages with the tooth plate 52 to allow the tooth plate 52 to push the movable plate 5 to move with the assistance of the limit block 51. After the movable plate 5 moves, it pulls the pull plate 33 to move. The pull plate 33 uses the insertion rod 4 and the sleeve 41 to pull the card block 31 through the restriction of the slider 42, thereby pulling the card block 31 out of the card slot 21, and then drives the outer frame 11 to pull the insertion block 2 out of the fixed plate 3.
