The invention provides a portable overhauling platform, and belongs to the technical field of electric power auxiliary tools. The portable overhauling platform comprises a face plate and at least three telescopic supporting legs spherically hinged to the lower side of the face plate, and hinge positioning pieces are arranged at the hinged positions of the telescopic supporting legs and the face plate. According to the portable overhauling platform, the problem that the adjustment direction of supporting legs of an existing overhauling platform is fixed is solved, independent adjustment of theangles of the supporting legs can be achieved, effective leveling of the overhauling platform is achieved under the situation that the ground surface is not flat or the space is limited, and using isconvenient.
