Abstract
A lifting positioning structure for a ladder tool platform comprises a ladder. The ladder comprises front supporting legs, rear supporting legs, connectors fixedly connected to the front supporting legs, plug pins, and elastic parts, wherein each front supporting leg includes a big tube and a small tube which are able to relatively move in an extension direction. The connectors are formed with vertically-through installation cavities which allow the big tubes to be inserted therein. The big tubes are arranged in the installation cavities and are fixedly connected to the connectors which extend to form connection parts rotationally connected to the rear supporting legs. The small tubes are connected to a tool platform. The plug pins are movably arranged on the connectors or the big tubes.
