The invention, which relates to the technical field of power construction, discloses a live-line live-line operation parallel groove clamp installation tool and a use method thereof, and the tool comprises a support, a fastening
assembly, a rotating
assembly, a clamping
assembly, a drainage wire pre-fixing assembly, a positioning assembly and a control assembly. A pin shaft eyebolt in the spring pin shaft mechanism is pulled open and released, so that a pin shaft enters a circumferential positioning hole of a
flange, angle adjustment of an insulating rod and an installation tool is achieved, the operation requirements of different working angles are met, the pre-tightening mechanism is driven through the elastic
pipe clamp and the steering engine, pre-fixing and releasing of a drainage wire are achieved, and the working efficiency is improved. Through the fixed end guide rail and the movable end guide rail, positioning and guiding of the transmission conductor are realized, the transmission conductor is accurately guided into the parallel groove clamp, and the reliability of installation operation is effectively ensured.
