The invention relates to a distribution line overhaul operation tool, specifically to pliers for easy buckling of an insulation box, thereby solving the technical problem that a packaging nail is not easy to buckle in an insulation box buckling and packaging process at present. The pliers for easy buckling of the insulation box include pliers, a plier jaw inner side face of the pliers is provided with a circular groove matched with a head of a packaging nail, and the other plier jaw inner side face is provided with a through hole matched with the packaging nail in a position corresponding to the groove. After using the pliers for easy buckling of the insulation box, work efficiency is improved, operating time is shortened, and insulating gloves can be effectively prevented from being punctured; and the whole device is simple in structure, and low in production cost.
