Telescopic insulating wire clamping device

The invention discloses a telescopic insulating wire clamping device, and relates to the technical field of power operation auxiliary tools. The telescopic insulating wire clamping device comprises abushing, a movable rod and a clamping device, wherein the movable rod is sleeved in the bushing and can slide relatively, the clamping device is fixedly connected with the top end of the movable rod,a trigger mechanism, a transmission mechanism and a lock catch mechanism which are sequentially connected in a sliding mode are arranged in the movable rod, and a lock opening matched with the lock catch mechanism is formed in the wall of the bushing. According to the invention, the telescopic insulating wire clamping device is simple in structure and convenient to operate; and stretching and retracting of the bushing and the movable rod can be rapidly achieved by pressing the trigger mechanism in the using process, so that convenience and rapidness are achieved, and different requirements ofelectric power operation st
