The present utility model discloses a tool for live-line replacing a large disc diameter and deadweight dead end insulator string. The tool comprises an insulator bracket, a front card, a back card and a retractable device for connecting the front card and the back card, and adjusting the relative distance between the front card and the back card conveniently. The tool has the following advantages: by designing the front card and the back card as a broadsword card form, the front card and the back card can be connected tightly with a front yoke plate and a back yoke plate, thus the whole tool can maintain good horizontal stability, enabling force bearing points to stand at the same level and keeping equal forcing of the retractable device; by arranging a suspension ring on the front broadsword card, the insulator bracket can be controlled by ground electricians on the scene, thus adjusting can be realized conveniently and the labor intensity of operating personnel on towers can be reduced. The method can flex
