The outer shape of the threaded barrel 7 is rectangular, and the cross-sectional shape and size of the threaded barrel 7 are the same as the cross-sectional shape and size of the first strip groove 3. The outer surface of the threaded barrel 7 is in sliding contact with the inner surface of the first strip groove 3, so that the threaded barrel 7 can move in the first strip groove 3. At the same time, the threaded barrel 7 can be limited by the first strip groove 3. A connecting block 8 is fixedly installed on the surface of the threaded barrel 7, and a pull rod 9 is rotatably installed on the surface of the connecting block 8. A second strip groove 10 is provided on one side surface of the connecting plate 2, and a fixing block 11 is fixedly installed inside the second strip groove 10. The pull rod 9 is rotatably connected to the fixing block 11 at one end away from the connecting block 8. Two fixing rods 16 are fixedly installed on the surface of the connecting plate 2 at one side away from the second strip groove 10, and a mounting plate 17 is fixedly installed on the end of the fixing rod 16 away from the connecting plate 2. A plurality of mounting grooves 18 are provided on the surface of the mounting plate 17 at one side away from the fixing rod 16.

[0022] A heat dissipation fin 19 is fixedly mounted on the surface of the mounting plate 17 on one side away from the mounting groove 18. There are multiple heat dissipation fins 19, and the spacing between two adjacent heat dissipation fins 19 is equal. The heat dissipation efficiency of the surface of the mounting plate 17 can be improved through the heat dissipation fins 19, and the heat generated by the components after they are mounted on the surface of the mounting plate 17 can be prevented from being too concentrated on the mounting plate 17. A protective cover 20 is rotatably mounted on the side surface of the switch cabinet body 1, and the rotating block 15 is located in the protective cover 20. The protective cover 20 can protect the connection between the rotating block 15 and the switch cabinet body 1, and can prevent dust or debris from entering the connection between the rotating block 15 and the switch cabinet body 1 to cause the rotating block 15 to rotate unsmoothly.

[0023] It should be noted that, in this embodiment, there are multiple mounting plates 17 , and the multiple mounting plates 17 are evenly distributed in the switch cabinet body 1 .

[0024] It should be noted that a cabinet door is provided on the front surface of the switch cabinet body 1 in this embodiment.

[0025] It should be noted that, in this embodiment, the thread directions of the first threaded rod 4 and the second threaded rod 6 are opposite.

[0026] The working principle of the above embodiment is:

[0027] When in use, the connecting rod 14 is rotated by the rotating block 15, so that the connecting rod 14 drives the first threaded rod 4 and the second threaded rod 6 to rotate in the first strip groove 3, and the threaded barrel 7 is limited by the first strip groove 3, so that the threaded barrel 7 can move on the first threaded rod 4 and the second threaded rod 6. Since the thread directions of the first threaded rod 4 and the second threaded rod 6 are opposite, when the first threaded rod 4 and the second threaded rod 6 rotate, the two threaded barrels 7 can move back or relative to each other at the same time, and the threaded barrel 7 can drive the connecting block 8 and one end of the pull rod 9 when moving. When the two threaded tubes 7 move relative to each other, the end of the pull rod 9 away from the fixed block 11 gradually approaches, and then the fixed block 11 and the connecting plate 2 can be pushed to move in the direction away from the first strip groove 3, so that the connecting plate 2 and the mounting plate 17 are closer to the opening of the switch cabinet body 1. At this time, the mounting plate 17 can be staggered with the original components in the switch cabinet body 1, thereby facilitating the installation of new components. When the installation is completed, you only need to rotate the first threaded rod 4 and the second threaded rod 6 in the opposite direction to pull the connecting plate 2 and the mounting plate 17 back into the switch cabinet body 1.
