[0021] Specifically, a mounting base 2 is provided on the lower surface of the shell body 1, and four pulley brackets 3 are evenly provided on the mounting base 2, and each pulley bracket 3 is connected to a corresponding sliding wheel 4. A rotating shaft 5 is rotatably connected to the mounting base 2, and a gear 7 is provided on the rotating shaft 5. The gear 7 is meshed with a rack 8, and the rack 8 is connected to a support plate 9. A plurality of guide rods 11 are evenly provided on the support plate 9, and corresponding guide holes 12 are evenly provided on the mounting base 2. Each guide rod 11 passes through the corresponding guide hole 12, and a plurality of guide rods 11 are slidably connected to the mounting base 2. By rotating the rotating shaft 5, the gear 7 is driven to rotate, and the gear 7 drives the rack 8 and the support plate 9 to move up and down along the direction of the guide rod 11 until the anti-slip pad 10 is tightly attached to or separated from the surface of the electrical cabinet.

[0022] Specifically, the shell body 1 includes a front side panel 13, a box frame 14, a rear side panel 15, a top panel 16 and a cooling fan 19. The mounting base 2 is connected to the bottom plate of the box frame 14. The box frame 14 is also threadedly connected to the front side panel 13, the rear side panel 15, the left and right side panels and the top panel 16 through a plurality of screws. A plurality of cooling holes are evenly arranged on the front side panel 13 and the rear side panel 15, and a corresponding handle groove 18 is respectively provided on the left and right side panels. A plurality of cooling fans 19 are installed on the front side panel 13.
