There are a plurality of rotating shafts 153, and a rotating ball 151 is nested on the outer side of the plurality of rotating shafts 153, and the outer side of the rotating ball 151 contacts the inner side of the side door 11. The inner cabinet body 3 includes a cabinet shell 33, and a plurality of mounting frames 32 are fixedly installed inside the cabinet shell 33. A plurality of through holes 31 are opened inside the cabinet shell 33. The main cabinet device 2 includes a main door 23, and a plurality of perforated convex plates 21 are fixedly connected to the main door 23. A handle 22 is fixedly connected to the main door 23, and the outer side of the perforated convex plate 21 is nested with the inner side of the side cabinet device 1, the outer side of the limit rod 12 cooperates with the inner side of the spring 17, the outer side of the movable structure 15 is nested with the inner side of the limit groove 13, and the inner side of the pressing block 16 is nested with the inner side of the limit rod 12.

[0024] The diameter of the small shaft inside the moving structure 15 is smaller than the diameter of the limiting groove 13 , so that the moving structure 15 can move more smoothly in the limiting groove 13 .

[0025] The size of the inner slot 14 is consistent with that of the perforated convex plate 21, and the hole inside the perforated convex plate 21 is consistent with the diameter of the inner shaft of the movable structure 15, so that the power cabinet that is easy to maintain can be installed together more stably.

[0026] The through hole 31 , the limiting groove 13 , and the movable structure 15 are located on the same straight line, so that the movable structure 15 can pass through the through hole 31 and the limiting groove 13 when the power cabinet that is easy to maintain is in use.

[0027] The working principle of the present invention is explained as follows: the various mechanical structures inside the power cabinet for easy maintenance are all fixed by threads unless otherwise specified.
