The invention relates to a storage box, in particular to a multi-functional tool storage box for electricity. The invention aims to solve the technical problem of providing the multi-functional tool storage box for electricity which is smaller in height and thus is convenient to convey. For solving the technical problem, the multi-functional tool storage box for the electricity comprises an arc cover plate, an assembly frame, a first connection plate, a second connection plate, a first fixed plate, a first guiding rod, a first elastic component and a U-shaped insertion rod, wherein the arc cover plate is hinged to the top of one side of the assembly frame; the first connection plate is fixedly connected to the outer side of the arc cover plate; and a first groove is formed in one side of the first connection plate. By adopting the multi-functional tool storage box, the effects that the height of the storage box is reduced, and transportation is convenient are realized.
