Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] like Figures 1-4As shown, a power distribution box with an adjustable guide rail bracket includes a power distribution box body, which includes a box 12 with a rectangular cross-section. A long guide rail bracket 1 is provided inside the box 12. A first box connecting piece 7 and a second box connecting piece 6 are respectively provided on the left and right side walls of the box 12. A bent first bracket connecting piece 2 is provided on the right side of the first box connecting piece 7. The upper part of the first bracket connecting piece 2 is detachably connected to the first box connecting piece 7. A bent second bracket connecting piece 3 is provided on the left side of the second box connecting piece 6. The upper part of the second bracket connecting piece 3 is detachably connected to the second box connecting piece 6. The lower part of the first bracket connecting piece 2 has a first opening for the left end of the guide rail bracket 1 to pass through.
