The invention discloses a multifunctional processing device for foreign materials on a power transmission line. The multifunctional processing device for the foreign materials on the power transmission line comprises an insulating operating rod, wherein an operating tool bit is connected to the front end of the insulating operating rod, the insulating operating rod and the operating tool bit are connected through a tooth-shaped connector, and different included angles can be formed between the insulating operating rod and the operating tool bit through rotation motion when the tooth-shaped connector is connected. The multifunctional processing device for the foreign materials on the power transmission line can be used for processing the foreign materials which are not tightly wound on an electric wire, and can also be used for processing thin ropes which are wound on the electric wire, the different angles of the tool bit can be adjusted so that the foreign materials can be processed more conveniently and more easily, the power transmission line cannot be easily damaged, the distance between a worker and the processed foreign materials or between the worker and the power transmission line can be measured, the worker can be kept away from the power transmission line, and personal safety of the worker is ensured.
