The blade pressing plate is higher than the blade, so that the blade edge is protected, and accidental injury during work is prevented.
The guide pulley and the in-groove guide rolling shaft penetrate through one side of the U-shaped cable groove through the pin, then penetrate through the guide pulley and the in-groove guide rolling shaft, then penetrate through the other side of the U-shaped cable groove and are fixed through the check ring; the guide pulley and the guide rolling shaft in the groove can roll freely and flexibly by taking the pin as an axis.
The pressing sheet guide rolling shaft penetrates through one side of the arc-shaped pressing sheet by a pin, then penetrates through the pressing sheet guide rolling shaft, then penetrates through the other side of the arc-shaped pressing sheet and is fixed by a check ring; the pressing sheet guide rolling shaft can roll freely and flexibly by taking the pin as an axis.
The blade is provided with scales, the scales start counting towards the upward direction far away from the U-shaped cable groove, the scale 0 of the blade corresponds to the inner plane of the groove of the blade pressing plate, the topmost end of the side cutting edge is flush with the concave arc bottom of the guide pulley when the scale 0 of the blade is used, and the scales are adjusted by loosening the butterfly bolt of the blade; the same method of operation allows easy replacement of the blade.
The blade both ends all are provided with the cutting edge, and one end is the arc cutting edge, and the other end is the cutting edge of side cutting edge of a knife or a sword.
The U-shaped cable groove, the blade pressing plate and the arc pressing plate are made of aluminum alloy materials which are subjected to corrosion resistance, wear resistance and weather resistance and are subjected to hard anodic oxidation treatment.
The blade is made of Cr12MoV steel with high hardness, good wear resistance and high strength.
The butterfly bolt, the guide pulley, the in-groove guide rolling shaft and the pressing sheet guide rolling shaft are all made of 304 stainless steel materials with corrosion resistance and high strength.
The principle and the using method of the invention are as follows: firstly, adjusting the scale of a blade according to the thickness of an outer sheath of a secondary cable needing to be stripped; secondly, placing the cable into the U-shaped cable groove from a gap between the U-shaped cable groove and the arc-shaped pressing sheet, holding the U-shaped cable groove by two hands or one hand, and simultaneously pressing the arc-shaped pressing sheet by a thumb with proper force to fix the stripped cable; then, the cable stripping tool is pulled at a constant speed along the cable stripping direction, and the side cutting edge of the blade can easily cut off the outer sheath of the cable; and finally, cutting off the stripped cable outer sheath by using the arc-shaped cutting edge of the blade, so that the stripping of the cable outer sheath is finished. After the cable armor layer is unfolded and taken down by the arc-shaped cutting edge of the blade, the inner sheath of the secondary cable can be stripped in the same step. The scale of the blade can be adjusted by loosening the butterfly bolt by hand, the butterfly bolt is fastened to fix the blade after the scale of the blade is adjusted, and the blade can be easily replaced by the same operation method.
The invention has the beneficial effects that: the wire stripping device is simple in structure, small and exquisite, easy to hold, time-saving and labor-saving to operate, wear-resistant, durable and not easy to break, and does not damage arms and cables in the wire stripping process; has the advantages of safety, reliability, convenience, rapidness and the like.
