The invention discloses an electric power construction tool, and belongs to the field of electric power. The electric power construction tool comprises a ratchet wrench (1) and is characterized in that a front end (101) of the ratchet wrench is movably connected with a differential screw (2); an upper end (201) of the differential screw and a lower end (202) of the differential screw are movably connected with a plurality of force transferring levers (3) respectively; an outer side (3011) of the front end of the force transferring level is connected with a base (4), an inner side (3012) of thefront end of the force transferring level is connected with a tool rest (5); a front end (501) of the tool rest is connected with a cutting tool (6); and a front end (401) of the base is connected with a nut fixing device (7). According to the electric power construction tool provided by the invention, a nut to be cut is placed in a third groove of the nut fixing device through connection of thecutting tool and the tool rest and the connection of the nut fixing device and the base, and then the ratchet wrench is pushed to enable the cutting tool to cut the nut, so that nut cutting is enabledto be more time and labor saving and not easy to injure workers.
