A limiting plate 15 is slidably connected in the inner cavity of the limiting groove 14. One end of the limiting plate 15 close to the sliding rod 13 is fixed to the sliding rod 13. When the staff needs to repair the circuit board 4, the staff pulls up the limiting plate 15, so that the limiting plate 15 drives the sliding rod 13 to displace. Along with the displacement of the sliding rod 13, the surface of the sliding rod 13 drives the first slider 17 to slide in the inner cavity of the first spring 18, and at the same time stretches the first spring 18 to store energy. As the surface of the limiting plate 15 gradually disengages from the inner cavity of the limiting groove 14, at this time, the circuit board 4 will no longer be restricted by the limiting plate 15. The staff pulls the pull ring 10 to drive the placement plate 9 to displace, so that the placement plate 9 drives the inner cavity of the connecting block 8 to slide on the surface of the sliding column 7. Along with the displacement of the connecting block 8, the surface of the connecting block 8 drives the third slider 23 to slide in the inner cavity of the third chute 22, and at the same time drives the second spring 21 to stretch and store energy. At the same time, the placement plate 9 drives the circuit board 4 to displace outwards. Through the setting of the above structure, it is convenient for the staff to pull out the circuit board 4, and thus it is convenient for the staff to repair the circuits on the surface of the circuit board 4.

A first slider 17 is slidably connected in the inner cavity of the first chute 16. One end of the first slider 17 close to the sliding rod 13 is fixed to the sliding rod 13. The staff pulls the limiting plate 15 to drive the sliding rod 13 to displace, so that the sliding rod 13 drives the surface of the first slider 17 to slide in the inner cavity of the first chute 16. Through the setting of the above structure, when the sliding rod 13 displaces, it maintains a directional displacement, preventing the sliding rod 13 from shifting and affecting the clamping of the limiting plate 15 and the limiting groove 14.

[0025] Refer to Figure 5 As shown in the figure, in this embodiment: A first spring 18 is fixed in the inner cavity of the hollow block 12. The top end of the first spring 18 is fixed to the sliding rod 13. The staff pulls the limiting plate 15 to drive the sliding rod 13 to displace, so that the sliding rod 13 drives the first spring 18 to stretch and store energy. Through the setting of the above structure, the rebounding force of the first spring 18 continuously stretches the sliding rod 13 to reset, and at the same time drives the surface of the limiting plate 15 to continuously engage and limit with the limiting groove 14.

[0026] Refer to Figure 1, Figure 2 and Figure 5 As shown in Figure 2 and Figure 5 , in this embodiment: a second chute 19 is provided inside the control cabinet body 1, and a second slider 20 is slidably connected to the inner cavity of the second chute 19. One end of the second slider 20 close to the square block 11 is fixed to the square block 11.

At the same time, the circuit board 4 drives the square block 11 to move, so that the square block 11 drives the surface of the second slider 20 to slide in the inner cavity of the second chute 19. Through the setting of the above structure, the top of the circuit board 4 maintains a directional displacement during displacement, preventing the circuit board 4 from tipping over and affecting the normal use of the device.

[0027] Referring to Figure 3 As shown in Figure 3 , in this embodiment: a second spring 21 is fixed to the inner cavity of the opening groove 6, and one end of the second spring 21 close to the connecting block 8 is fixed to the connecting block 8. The staff pulls the pull ring 10 to drive the storage board 9 to move, so that the storage board 9 drives the connecting block 8 to move. As the connecting block 8 moves, the connecting block 8 drives the second spring 21 to stretch and store energy. Through the setting of the second spring 21, the second spring 21 drives the connecting block 8 to reset, and at the same time drives the storage board 9 and the circuit board 4 to reset, facilitating the circuit board 4 to return to the inner cavity of the control cabinet body 1 for normal use.

[0028] Referring to Figure 3 As shown in Figure 3 , in this embodiment: a third chute 22 is provided in the inner cavity of the control cabinet body 1, and a third slider 23 is slidably connected to the inner cavity of the third chute 22. One end of the third slider 23 close to the connecting block 8 is fixed to the connecting block 8.

[0029] Working principle: When the staff needs to repair the circuit board 4, the staff pulls the limit plate 15 upward, causing the limit plate 15 to drive the sliding rod 13 to displace. Along with the displacement of the sliding rod 13, the surface of the sliding rod 13 drives the first slider 17 to slide within the inner cavity of the first spring 18, while stretching the first spring 18 to store energy. As the surface of the limit plate 15 gradually disengages from the inner cavity of the limit groove 14, at this time, the circuit board 4 will no longer be restricted by the limit plate 15. The staff pulls the pull ring 10 to drive the storage plate 9 to displace, causing the storage plate 9 to drive the inner cavity of the connecting block 8 to slide on the surface of the sliding column 7. Along with the displacement of the connecting block 8, the surface of the connecting block 8 drives the third slider 23 to slide within the inner cavity of the third chute 22, while driving the second spring 21 to stretch and store energy. At the same time, the storage plate 9 drives the circuit board 4 to displace outward. Through the setting of the above structure, it is convenient for the staff to pull out the circuit board 4, and thus convenient for the staff to repair the circuits on the surface of the circuit board 4.
