Abstract

The utility model relates to a wire and cable sheath stripper, belonging to a cutter. A limitation sheet is additionally arranged on the lower part of the utility model and a plurality of notches with different depth are arranged on the upper part of the utility model on the basis of the existing paper cutter. One side of an arrowhead-shaped outer shell is designed into a V-shaped groove. The transverse stripping of the cable can be carried out by the cooperation of a blade and the limitation sheet, and the longitudinal stripping of the cable can be carried out by the cooperation of the V-shaped groove and a cutter tip. The utility model can also be used as a cutter, having the advantages of simple structure, controllable stripping depth, convenient operation, etc.

Description

Wire and cable sheath-removing knife

The utility model belongs to the cutter class.

Used wire stripping skin instrument often is the folded form electrician's knife, when the wire stripping skin, entirely with operating personnel's experience with feel to carry out, can not control for the cross cutting degree of depth, often occurs too dark and damage electric wire or too shallow and be difficult to divest phenomenon; Can not control its cutter mark during straight-cut, the sliding cutter of normal generation, sideslip or scuffing operating personnel.

The purpose of this utility model will provide a kind of cross cutting line skin depth controlled system exactly, can locate the bark knife of depth controlled during straight-cut line skin.

The utility model is on the basis of existing paper knife, increases by a wire stripping skin degree of depth and limits sheet.Limit sheet and be positioned under the blade, design the recess that has several sizes to differ above, blade all is positioned at same end with the locating piece and the flexible piece that limit sheet, can telescopic moving in the profile of tooth slideway in the middle of the shell that is made of plastics.Be positioned at blade and the shell termination that limits the sheet gateway, be designed to an asymmetry arrowhead form.Short hypotenuse is designed to a plane opening, and long hypotenuse is designed to a V-shape groove, and opening communicates with groove, and the point of a knife of blade can stretch out from plane opening and the common connection of V-shape groove.During use, according to the line skin thickness of electric wire, cable, promote blade earlier, promotion limits sheet again, locatees respectively then, and electric wire is put into blade and limits sheet respective depth part, by blade cuts, till electric wire touches the qualification sheet, carries out the transverse cuts peeling.When vertically cutting stripping, the blade of cutting somebody's hair, the length that point of a knife is exposed is consistent with the line skin thickness that will cut, locate then, electric wire is placed on the V-shape groove along long hypotenuse,, makes it to be difficult for rolling because the V-shape groove has blocked electric wire, cut when drawing skin not sideslip, thereby guaranteed its fail safe and high efficiency.

Blade is stretched out, and the location also can be used as a regular knife and uses, in addition, blade with limit sheet and also can be designed to one, promptly two are bonded together, by a flexible piece with decide the piece manipulation.

The utility model adopts this structure, has the high handled easily of efficient, and the wire stripping skin depth is adjustable, and is simple in structure, and characteristics such as practicality are specially adapted to 6mm ²Above electric wire peeling.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the utility model blade and the schematic diagram that limits sheet.

Fig. 3 is the utility model shell termination schematic diagram.

Shown in Fig. 1 .2, the termination of blade 2 is fixed with locating piece 4 and flexible piece 5, and an end that limits sheet 3 is fixed with locating piece 7 and flexible piece 6, and other end design has the deep mixed recess of 1～4mm 8.Blade 2 and all overlapping slideway that is positioned at plastic casing 1 centre of qualification sheet 3, the space width of slideway both sides sawtooth 9 is 0.5mm.

As shown in Figure 3, blade 2 is an asymmetry arrow shaped with the discharge case termination 10 that limits sheet 3, and long hypotenuse 11 is a V-shape groove, and short hypotenuse 12 is a plane, and outlet 13 communicates with both sides, and its size is advisable can allow blade freely to stretch with the qualification sheet.

Claims

1, a kind of electric wire bark knife, by shell, blade, flexible piece, locating piece are formed, and it is characterized in that: design has one to limit sheet 3 under blade 2, and shell termination 10 is an asymmetry arrow shaped.

2, according to the said electric wire bark knife of claim 1, it is characterized in that: limiting to design on the sheet 3 has deep mixed recess 8.

3, according to the said electric wire bark knife of claim 1, it is characterized in that: the long hypotenuse 11 of shell termination 10 is designed to the V-shape groove, and short hypotenuse 12 is a plane opening.Outlet 13 is connected with both sides.
