The outer end of spring 10-4 is in contact with the inner wall of the outer side of the moving groove 3-2, and the inner end of spring 10-4 is in contact with the limiting boss 10-1. Using the above design scheme, the connecting rod 10-2 drives the limiting boss 10-1 to be inserted into the annular groove 5-1, thereby locking and limiting the locking post 5.

[0026] Example 3:

[0027] Please see Figures 1-9 Based on Embodiment 2, a further improvement is made: a connecting base block 11 is provided between the two frustums 10-3 on the same side; and a clamping assembly 12 is provided on the outer side of the connecting base block 11; the clamping assembly 12 includes: Left side frame 12-1, there are two left side frames 12-1, which are slidably disposed in the sliding grooves opened in opposite directions on the outside of the connecting base block 11; the left side frame 12-1 is configured with an "L" shape, the vertical end of the left side frame 12-1 is attached to the left side of the connecting base block 11, and the horizontal end of the left side frame 12-1 is in contact with the outside of the connecting base block 11. There are two right side frames 12-2, which are slidably disposed in corresponding sliding grooves, and the right side frames 12-2 are symmetrically disposed with the left side frame 12-1; the vertical end of the right side frame 12-2 is attached to the right side of the connecting base block 11, and the horizontal end of the right side frame 12-2 is in contact with the outside of the connecting base block 11. Two bidirectional lead screws 12-3 are arranged opposite each other between the connecting base block 11 and the fixing clip 3.

The left and right ends of the bidirectional lead screws 12-3 are respectively screwed onto the fixing clip 3 by bearings and bearing seats. After the right end of the bidirectional lead screw 12-3 passes through the bearing seat, it is connected to the rotating disk 12-4. The locking screw 12-5 passes through the rotating disk 12-4 by thread rotation and is screwed into the bearing seat. Using the above design scheme, the bidirectional lead screw 12-3 rotates, causing the left frame 12-1 and the right frame 12-2 to move synchronously, thereby limiting and clamping the connecting base block 11.

[0028] Example 4:

[0029] Please see Figures 1-9 Based on embodiment 3, further improvements are made. The horizontal ends of the left frame 12-1 and the right frame 12-2 are provided with slots 12-6 on opposite sides.

[0031] The beneficial effects of this specific embodiment after adopting the above structure are as follows: 1. The limiting boss 10-1 engages with the annular groove 5-1 of the card insertion post 5, positioning the card insertion post 5 and tightly connecting the fixing card 3 and the positioning card block 4. 2. The connecting base block 11 is limited by the relatively movable left side frame 12-1 and right side frame 12-2, so that the position of the limiting boss 10-1 is fixed, and the fixing of the fixing piece 3 and the positioning piece 4 is reinforced. 3. The cooperation between the locking block 12-7 and the reinforcing protrusion 12-9 makes the contact between the left frame 12-1 and the right frame 12-2 more stable.
