In other embodiments, the second outer hanger 32 may be integrally formed with the toolbox case. When the first connecting portion 1 of the first outer hanger 31 and the second connecting portion 2 of the second outer hanger 32 are unlocked from each other, the first outer hanger 31 is separated from the storage box 20; when the first connecting portion 1 of the first outer hanger 31 and the second connecting portion 2 of the second outer hanger 32 are interlocked, both the first outer hanger 31 and the second outer hanger 32 are connected to the storage box 20. In this embodiment, the second external hanger 32 is provided with a plurality of second connecting portions 2, and the plurality of second connecting portions 2 have different unlocking directions, and the unlocking directions are opposite; thus, the plurality of second connecting parts 2 can be locked with the plurality of first connecting parts 1, thereby carrying a plurality of other tools. In addition, the second connecting portion 2 of the second outer hanging piece 32 is further provided with a limiting column 23 which is matched with the limiting groove 13, and the limiting column 23 can be contained in the limiting groove 13, so that the first outer hanging piece 31 and the second outer hanging piece 32 are firmer when being locked with each other, and the requirement of carrying heavier tools is met.

The above description is only for the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art can easily think of the changes or substitutions within the technical scope of the present invention, and all should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
