The invention discloses an electric power overhauling tool cabinet which comprises a cabinet cover and a cabinet body. The cabinet cover is installed on the cabinet body, the interior of the cabinet body is divided into a tool containing layer and a cable storing layer, the cable storing layer comprises a cable rolling shaft, a cable, a balance spring, a control switch, a power plug, a power socket and universal wheels arranged in grooves in a base plate of the cabinet body, the universal wheels are fixed into the grooves through U-shaped clamping sheets with elasticity, the grooves and the universal wheels are pivoted through rotating shafts, the universal wheels can be rotated around the rotating shafts by 180 degrees to be completely contained into the grooves, looped links arranged onthe universal wheels are matched with flat nozzle hasps correspondingly arranged on a side plate of the cabinet body, and the universal wheels are fixed outside the grooves. By means of the electric power overhauling tool cabinet, a cable reel can be provided when the distance between an overhauling position and a power source point is not enough, the power point coverage scope of the cable reel is enlarged, heavy electric power overhauling equipment can be conveyed, working strength of an overhauling person s reduced, and the working efficiency is improved.
