The invention discloses an electrical equipment maintenance stool/ladder. According to the electrical equipment maintenance stool/ladder, a frame structure composed of a rear-left extension leg, a first left support, a left rotation wheel, a second left support, a rear-left inclined leg, a front-left inclined leg and a front-left leg and a frame structure composed of a rear-right extension leg, a first right support, a right rotation wheel, a second right support, a rear-right inclined leg, a front-right inclined leg and a front-right leg are symmetrically arranged, and some of the nodes are connected through cross members, the frame structure composed of the front-left inclined leg, the second left support and the front-left leg can rotate by taking the left rotation wheel as the shaft, and meanwhile, the frame structure composed of the front-right inclined leg, the second right support and the front-right leg is driven to rotate synchronously by taking the right rotation wheel as the shaft. For the electrical equipment maintenance stool/ladder provided by the invention, the fast conversion between the electrical equipment maintenance stool and the electrical equipment maintenance ladder can be realized, and thus various functions are integrated; the structure is concise, the use is convenient, and the transportation and storage are convenient.
