The invention discloses a tool capable of quickly pulling out and restoring an insulator R pin, which belongs to the technical field of transmission line maintenance work. The tool comprises a sleeve (1) and a pulling rod (3), and is characterized in that the sleeve (1) is also internally provided with a knocking block (2) capable of sliding in the sleeve (1); the left end of the sleeve (1) is provided with a round hole matched with the diameter of the pulling rod (3); the middle of the sleeve (1) is provided with a round hole matched with the outer diameter of the knocking block (2); the right end of the sleeve (1) is provided with a wire hole matched with a wire tooth on a tail seat (4); the pulling rod (3) passes through the round hole at the left end of the sleeve (1) and slides in the round hole at the left end of the sleeve (1); and the left end of the pulling rod (3) is connected with a flat hook-shaped pulling hook (6), and the right end of the pulling rod (3) is connected with the knocking block (2). Problems that the insulator R pin is hard to pull out and restore, time and labor are consumed, a special insulator can not be used, and carrying for overhead work is inconvenient can be solved.
