An inclined surface 25 is provided at the bottom of the limit block 26, and the bottom of the inclined surface 25 is located inside the first chute 19. A second chute 17 is provided on the limit platform 1. The elastic mechanism 7 further includes a pressing block 21 slidably connected to the second chute 17. An adjusting rod 18 is provided on the pressing block 21. An inclined slot 16 is provided on the side wall of the limit block 26. One end of the adjusting rod 18 is located inside the inclined slot 16 and is tangent to the inner wall of the inclined slot 16. The bottom of the second chute 17 and the bottom of the pressing block 21 are connected through a second spring 23. In the initial state, the limit block 26 is inserted into the notch 15 under the action of the first spring 20. At the same time, the boss 24 is closely attached to the side wall of the groove 6. When it is necessary to extend the limit block 26 out of the notch 15, only need to press the pressing block 21, and the adjusting rod 18 will move downward. The inclined slot 16 will move outward under the action of the adjusting rod 18, so that the limit block 26 extends out of the notch 15, and then the plug connector can be taken out of the limit frame 9; when it is necessary to fix the plug connector inside the limit frame 9, only need to insert the plug connector into the limit frame 9. During the insertion process, the top of the plug connector presses the inclined surface 25, so that the limit block 26 moves outward. When the notch 15 is aligned with the limit block 26, under the action of the first spring 20, the limit block 26 will be inserted into the notch 15, thus realizing the fixation of the plug connector; in this embodiment, two inclined slots 16 are provided on one limit block 26, and four limit blocks 26 are provided. Therefore, eight pressing blocks 21 are connected through an annular plate 8. When pressing the annular plate 8, the pressing blocks 21 can be pressed simultaneously; and a plurality of sliders 22 are fixedly connected to the annular plate 8, and slide rails 11 that are slidably connected to the sliders 22 are fixedly connected to the outer wall of the limit frame 9, ensuring that when the annular plate 8 is pressed from all directions, the annular plate 8 will move in the vertical direction; and a limit plate 13 is slidably connected inside the limit frame 9. The limit plate 13 is connected to the top of the limit frame 9 through a third spring 12. The limit plate 13 is closely attached to the top of the plug connector, reducing the manufacturing precision of the notch 15 and the limit block 26 while further fixing the plug connector; and a plurality of reinforcing ribs 14 are provided inside the limit frame 9 to improve the strength of the limit frame 9; in addition, the bottom of the plug connector is an installation plate 2, and the installation plate 2 is fixedly connected to the printed circuit board 5 through a plurality of bolts 3, facilitating the disassembly and assembly of the printed circuit board 5; and a plurality of L-shaped grooves 4 are provided on the installation plate 2, and the bolts 3 are located inside the L-shaped grooves 4, thereby realizing the installation of printed circuit boards 5 of different sizes and improving the practicability of the device.

[0023] Working principle: When it is necessary to replace the printed circuit board 5, first press the pressing block 21, the adjusting rod 18 will move downward, and the inclined groove 16 will move outward under the action of the adjusting rod 18, so that the limiting block 26 extends out of the notch 15. Then, the plug connector can be taken out of the limiting frame 9, and the plug connector and the printed circuit board 5 can be placed on the table from a high place, thus facilitating the detachment of the plug connector and the printed circuit board 5. When the replacement of the printed circuit board 5 is completed, the plug connector is inserted into the limiting frame 9. During the insertion process, the top of the plug connector presses against the inclined surface 25, so that the limiting block 26 moves outward. When the notch 15 aligns with the limiting block 26, under the action of the first spring 20, the limiting block 26 will be inserted into the notch 15, thereby realizing the fixation of the plug connector and further realizing the replacement of the printed circuit board 5. Therefore, during the disassembly and assembly process of the printed circuit board 5 in this utility model, it is not necessary to remove the printed circuit board 5 by screwing at a high place, but to quickly remove the printed circuit board 5 and place it at a low place for removal, thus facilitating the replacement operation of the printed circuit board 5.
