Background technique

When stripping the insulation layer of overhead insulated wires in a live state, hand-held wire strippers and manual insulation rod wire strippers are currently more commonly used. The hand-held wire stripper requires manual operation with the insulated bucket. During the live operation, manual short-distance operation has a greater safety hazard, and the use of the insulated bucket is also limited by the site, and its versatility is poor. The manual insulation rod type wire stripper adopts the method of manually climbing the rod for long-distance operation. Compared with the hand-held wire stripper, it has higher safety and is not restricted by the site. However, the manual insulation rod type wire stripper currently used is manually rotated. Shake the handle as motivation. In the prior art, when the stripping reaches the required length and the cutting part needs to be peeled to cut off the insulation in situ, it is necessary to provide a lateral braking force along the wire direction. The hand-held wire stripper provides this braking force by hand, and the insulating rod is manually operated. The wire stripper requires an additional lock rod to be locked in the forward direction of the stripper on the wire, which is cumbersome to operate and has a certain degree of difficulty during pole-climbing operations. The prior art also needs to manually adjust the position of the cutting part cutter to control the peeling depth. Because the thickness of the wire insulation layer has many specifications, and the insulation layer thickness of the erected wire cannot be directly measured, the adjustment operation is relatively inconvenient.
