The utility model discloses a be applied to pin removal of insulator R round pin, including handheld portion, handheld portion is connected with the one end of connecting rod, and the other end AND operation portion of connecting rod connects, the operating portion is including the first cylinder and the second cylinder that parallel, and first cylinder and second cylinder all are connected with the connecting rod, just first cylinder and second cylinder all with the other end mutually perpendicular of connecting rod. Setting through first cylinder and second cylinder and connecting rod and handheld portion forms the lever structure, utilizes lever principle to carry out the write off, has solved original pincers of pulling pin and has been difficult to the difficult problem of carrying and wasting time and energy when pulling pin. The connecting rod of pin removal sets up the curved J type structure of banding, and what provide first cylinder department just in time is the power of outwards pulling out the R round pin, can pull out the R round pin for prism of first order body department provides bigger power simultaneously.
