[0059] like Figure 5 As shown: the card seat 5 includes:

[0060] Abutment member 6, wherein the abutment member 6 abuts against the mounting seat 1 in a sliding manner;

[0061] Slide blocks 7, the slide blocks 7 are fixedly arranged on both sides of the abutment member 6, and the slide blocks 7 are slidably connected to the mounting seat 1;

[0062] A first clamping member 8, wherein the first clamping member 8 is disposed at the bottom of the abutting member 6, and the first clamping member 8 is slidably clamped with the mounting seat 1;

[0063] The first rotating connecting member 9 is arranged on a side of the abutting member 6 away from the mounting seat 1 , and the first rotating connecting member 9 is located on both sides of the first clamping member 8 , and the first rotating connecting member 9 is rotatably connected to the clamping assembly.

[0064] A slide groove 10 is provided at the bottom of the mounting seat 1, and an inner wall of the slide groove 10 away from the expansion component is opened, and a first clamping groove 11 is provided on the inner wall of the slide groove 10 close to the expansion component, and limit members 12 are symmetrically provided on the inner side walls of both sides of the slide groove 10;

[0065] A first clamping plate 15 is provided on one side of the first clamping member 8 close to the mounting seat 1. The first clamping plate 15 extends in a direction close to the mounting seat 1. A first toggle portion 14 is provided at the bottom of the first clamping member 8. The first toggle portion 14 extends obliquely in a direction away from the first clamping plate 15.

[0066] The slider 7 is slidably disposed between the limiting member 12 and the inner wall of the slide slot 10 provided with the first engaging groove 11 , and the first clamping plate 15 is engaged with the first engaging groove 11 to achieve sliding engagement between the engaging seat 5 and the mounting seat 1 .

[0067] Specifically, in this embodiment, the position of the slide 10 is further explained. As can be seen from the above, the slide 10 is opened at the bottom of the mounting seat 1, that is, the opening direction of the slide 10 is at the bottom of the mounting seat 1, and on this basis, the inner wall of the slide 10 away from the expansion component is defined as an opening setting. What is meant here is that the inside of the slide 10 is connected to the outside through the opening position here, that is, the slide 10 is only surrounded by three interiors. It is also necessary to explain that the slider 7 is slidably set between the limiter 12 and the inner wall of the slide 10 with the first clamping groove 11, which means that the three outer side walls of the slider 7 slide against the inner wall with the first clamping groove 11, the side wall of the slide 10, and the outer wall of the limiter 12 adjacent to the side wall of the slide 10, respectively, and are tightly against each other.

[0068] In this embodiment, the slider 7 is provided with a limited sliding connection with the slide groove 10 so as to be tightly abutted against each other, so that the clamping seat 5 can be quickly and stably inserted into the slide groove 10 on the mounting seat 1, so as to realize the limited connection between the clamping seat 5 and the mounting seat 1 in the horizontal direction. At the same time, the clamping connection between the first clamping groove 11 and the first clamping plate 15 is provided to realize the limited connection between the clamping seat 5 and the mounting seat 1 in the vertical direction, and an inclined first toggle portion 14 is provided, so that the clamping relationship between the first clamping plate 15 and the first clamping groove 11 can be completed or contacted by toggling the first toggle portion 14. Specifically, by toggling the first toggle portion 14 in a direction away from the first clamping groove 11, it can The first clamping plate 15 is separated from the first clamping groove 11, and after the separation, the limit in the vertical direction is released, and the disassembly between the clamping seat 5 and the mounting seat 1 is completed by sliding between the slider 7 and the slide groove 10. During installation, after the slider 7 is directly slid into the slide groove 10, the first clamping member 8 will be tilted away from the first clamping groove 11 under the end face of the first clamping plate 15 against the inner wall of the slide groove 10, which is similar to the effect of manually toggling the first toggle member. When the first clamping plate 15 slides to the first clamping groove 11, the first clamping plate 15 loses its abutment, so that the first clamping member 8 straightens up, and the first clamping plate 15 automatically pops into the first clamping groove 11 to complete the installation.

[0069] like Figure 3 , 6 As shown in 7: the clamping assembly includes:

[0070] A first clamping plate, one end of which is provided with a second rotating connecting member 16, the second rotating connecting member 16 is rotatably connected to the first rotating connecting member 9, and a first rotating connecting portion 17 is provided on the lower end surface of the first clamping plate, the first rotating connecting portion 17 is located in the middle of the first clamping plate;

The two ends of the torsion spring are respectively abutted against the first clamping plate and the second clamping plate 18, so that the second clamping plate 18 becomes a lever structure with the second rotating connection part 19 as the fulcrum.

[0073] In the present embodiment, specifically, the rotating shaft passes through the first rotating connection part 17, the torsion spring and the second rotating connection part 19 to complete the connection between the first clamp plate and the second clamp plate 18, and the end of the torsion spring abuts against the first clamp plate and the second clamp plate 18. First, the abutting position is between the first rotating connection part 17 and the first rotating connection on the first clamp plate, and for the second clamp plate 18, the abutting position is between the end of the first clamp plate closer to the mounting seat 1 and the second rotating connection part 19, and regardless of the first clamp plate or the second clamp plate 18, the length of the part close to the mounting seat 1 is much smaller than the length of the part away from the mounting seat 1 based on the rotating shaft, that is, the first clamp plate and the second clamp plate 18 form a clamp structure under the connection of the rotating shaft and the torsion spring, and the opening direction of this frame structure is the end away from the mounting seat 1.

[0074] It should also be noted that, in the present embodiment, the rotational connection between the first rotating connector 9 and the second rotating connector 16 is a rotational connection that can be adjusted to multiple gears in the prior art, and can be stopped at any time after adjustment.
