The inner surface of the connecting plate 2 is slidably connected to the plug pin 5. A first spring 6 is fixedly connected to the lower surface of the plug pin 5. One end of the first spring 6 away from the lower surface of the plug pin 5 is fixedly connected to the first bracket 3. A card slot 7 is provided inside the plug pin 5. A support plate 8 is slidably connected to the side surface of the connecting plate 2. The inner surface of the support plate 8 is slidably connected to the plug pin 5. A first chute 9 is provided inside the support plate 8. A second chute 10 is provided inside the support plate 8. A second spring 11 is fixedly connected to the bottom of the second chute 10. The first end of the second spring 11 away from the bottom of the second chute 10 is fixedly connected to a latch 12. The number of latches 12 is two and they are distributed left and right. The side surface of the latch 12 is slidably connected to the card slot 7. The side surface of the latch 12 is slidably connected to the second chute 10. A push block 13 is slidably connected inside the support plate 8. The side surface of the push block 13 is slidably connected to the latch 12. A pressing block 14 is fixedly connected to the lower surface of the push block 13. The side surface of the pressing block 14 is slidably connected to the first chute 9. A second push rod 15 is fixedly connected to the right surface of the pressing block 14. A second bracket 16 is fixedly connected to the lower surface of the support plate 8.

[0025] Working principle: When installation is required, the side surface of the connecting plate 2 is attached to the support plate 8, and the first push rod 4 is pushed. The first push rod 4 drives the plug pin 5 to slide, and the plug pin 5 is inserted into the inside of the support plate 8. The plug pin 5 slides and presses the inclined surface of the latch 12, causing the latch 12 to slide to both sides. When the plug pin 5 slides to the top inner wall of the support plate 8, the top of the plug pin 5 no longer presses the inclined surface of the latch 12. At this time, under the action of the second spring 11, the latch 12 is driven to reset, causing the latch 12 to be stuck into the card slot 7. At this time, the card slot 7 is limited by the horizontal surface of the latch 12, and the plug pin 5 cannot be pulled up and down, so that the support plate 8 and the connecting plate 2 are fixed, achieving the effect of quick installation. When disassembly is required, the second push rod 15 is pushed. The second push rod 15 slides and drives the pressing block 14 to slide. The pressing block 14 slides and drives the push block 13 to slide. The push block 13 slides and drives the latch 12 to slide to both sides. When the card slot 7 loses the limitation of the latch 12, the first spring 6 drives the plug pin 5 to reset, causing the support plate 8 to lose the restriction, achieving the effect of quick disassembly. This device is simple to disassemble, and also has the effects of not being easy to lose parts and improving the maintenance efficiency.
