Disclosed is a tool specially used for rapidly handling foreign materials of a live wire and the tool is used for clearing the foreign materials on a power transmission line. A technical scheme adopted is as follows: the tool includes a single-handle jagged shear with jagged blade parts, a support body, a pulley fixed on a handle part of the single-handle jagged shear through a pulley seat and insulating ropes. The tool is characterized in that a lower blade of the single-handle jagged shear is provided with the handle part; the single-handle jagged shear is arranged at the upper part of the support body through movable hinging, wherein an upper blade is independently fixed on the support body; a spring, which is connected with a position of the support body, below a movable hinging position, is arranged near the movable hinging position of the lower blade and the handle part of the lower blade is provided with the pulley; and fixing rings, which are used for fixing one end of each rope, are arranged respectively at the top end, lower part and bottom part of the support body. The tool specially used for rapidly handling the foreign materials of the live wire is capable of rapidly clearing foreign materials such as plastic sheets and kite lines and the like on the power transmission line and the insulating ropes are used for control so that electric shocks are prevented.
