Live-line work insulation protection device

An insulation protection device for hot-line work comprises a sleeve, two fixing rings, two limiting grooves and two clamping rings, the two fixing rings are fixedly arranged on the two sides of the sleeve respectively, connecting rods are fixedly arranged at the tops of the two sides of the two fixing rings respectively, and clamping mechanisms are hinged to one ends of the two connecting rods respectively. The utility model relates to a live-line work insulation protection device. An electric wire is arranged between the two arc-shaped clamping grooves; the bolt is screwed to drive the boltto rotate; the bolt rotates to drive the second movable block in threaded connection with the bolt to move along the limiting rod; the electric wire is clamped through the relative movement of the twoarc-shaped clamping grooves; when the two clamping rings cannot be exactly matched with the two limiting grooves, the screwing sleeve can be screwed to drive the adjusting screw rod to rotate, the adjusting screw rod rotates
