Screw dismounting tool for mounting high-low voltage power supply and distribution system

The utility model discloses a screw dismounting tool for mounting a high and low voltage power supply and distribution system, which relates to the technical field of circuit construction, and comprises a holding assembly, the right end of the holding assembly is fixedly connected with a telescopic supporting mechanism, and the left end of the holding assembly is fixedly connected with a replaceable tool assembly. An electric telescopic rod in the telescopic supporting mechanism drives a supporting plate in the telescopic supporting mechanism to move rightwards, and the holding assembly and the replaceable tool assembly are supported. When a user carries out single-hand operation, supporting can be effectively achieved, then the situation that the end of the rod-shaped screwdriver is disengaged from the screw groove is avoided, the operation difficulty is lowered, and meanwhile actual use is more convenient. 本实用新型公开了一种用于高低压供配电系统安装用螺丝拆装工具，涉及到电路施工技术领域，包括握持组件，所述握持组件右端固定连接有伸缩式支撑机构以及握持组件左端固定连接有可更换式工具组件，所述伸缩式支撑机构中电
