The invention relates to an insulating rod assisting device for mounting a clamping plate type ground wire connector. Compared with the prior art, the insulating rod assisting device can assist in eliminating defects in using insulating gloves to mount a clamping plate t type ground wire connector. The insulating rod assisting device of the invention includes a rotation rear seat and a rotation handle; a screw thread hole A is formed at the tail end of an insulating rod; a screw thread hole B is formed at one end of the rotation rear seat; the other end of the rotation rear seat is provided with a square boss; the rotation rear seat sleeves the tail end of the insulating rod; a screw passes through the screw thread hole A and the screw thread hole B; the rotation handle is provided with a square groove; and the rotation handle can be mounted on the square boss of the rotation rear seat through the square groove. With the insulating rod assisting device of the invention adopted, a user, who wears insulating gloves, can perform rotation operation on the insulating rod with easiness, and therefore, the mounting of the clamping plate type ground wire connector can be facilitated, and traditional manual intermittent rotation can be converted into continuous rotation, and working efficiency can be improved.
