Description

Electrician's wire stripper

Technical field

The utility model relates to a kind of wire stripper that is used for electrical field.

Background technology

At present, when copper core or aluminium core electric wire are stripped out the end of a thread, usually adopt wire stripper that outer field PVC or rubber insulation are peeled off, but the shortcoming that present widely used wire stripper ubiquity complex structure, insulating barrier are difficult to peel off fully, in the time of particularly need stripping out the end of a thread in the centre position of electric wire, existing wire stripper also can't be realized, still adopts the mode of manual wire stripping.

The utility model content

The purpose of this utility model is the above-mentioned deficiency at prior art, and a kind of electrician's wire stripper is provided, and it has simple in structure, insulating barrier and peels off clean advantage, and can strip out the end of a thread in the centre position of electric wire.

For achieving the above object, electrician's wire stripper of the present utility model, comprise pivot pin, be installed on the pivot pin on, lower house and torsion spring, the two ends of torsion spring are respectively with last, the lower house contact, on, lower house all is installed with handle, it is characterized in that last, the side that lower house is adjacent is equipped with axial wire casing, two wire casings are formed the line hole, last, all set firmly the horizontal cutter fixed head in a back in the lower house, all also be provided with axial wire casing in the adjacent side of the two horizontal cutter fixed heads in back, be installed with the radially back horizontal blade of cutting edge on each horizontal cutter fixed head in back, last, all be installed with shell fragment on the lower house, the feed briquetting is housed on the every shell fragment, last, be equipped with chute radially more than one or one in the lower house, perpendicular knife rest is housed in the per pass chute slidably, every perpendicular knife rest is installed with the perpendicular blade of axial cutting edge near an end of wire casing, perpendicular blade is near the back horizontal blade of correspondence, and the other end of all perpendicular knife rests is connected with each self-corresponding feed briquetting.

During use, pinch upper and lower handle simultaneously, upper and lower casing rotates and opens around pivot pin, electric wire is put between the upper and lower casing, release handle, upper and lower casing resets under the effect of torsion spring, the insulating barrier of the back horizontal blade incision electric wire on it, the rotation half-turn, the horizontal blade in back is radially cutting off insulating barrier; Pinch the feed briquetting again, the insulating barrier of all perpendicular blade incision electric wires, move forward wire stripper vertically up to wire end, perpendicular blade is cut the insulating barrier that cuts off open vertically, insulating barrier comes off naturally, finishes the wire stripping to wire end, and the utility model is simple in structure, owing to have the perpendicular blade more than two to cut insulating barrier open, peel off clean.

As further improvement of the utility model, horizontal cutter fixed head before in upper and lower casing, all also setting firmly one, the side that horizontal cutter fixed head is adjacent before two all also is provided with axial wire casing, be installed with the radially preceding horizontal blade of cutting edge on the horizontal cutter fixed head before each, all perpendicular blades are axially between the horizontal blade of preceding horizontal blade and back; Described feed briquetting is loaded on the corresponding shell fragment slidably, described chute between axial length and the horizontal blade of preceding horizontal blade and back apart from corresponding; The setting of preceding horizontal blade can strip out the end of a thread in the centre position of electric wire.

As further improvement of the utility model, on all perpendicular knife rests, be equipped with shoulder, the oral area in the upper and lower casing per pass chute outside is installed with the baffle plate with corresponding perpendicular knife rest shoulder contact; Baffle plate can position the return of perpendicular knife rest, shortens the stroke of perpendicular knife rest, and is easy to operate.

In sum, the utlity model has simple in structure, insulating barrier and peel off clean advantage, and can strip out the end of a thread in the centre position of electric wire, and easy to operate.

Embodiment

Below in conjunction with accompanying drawing the utility model is described in further detail.

By Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5 and shown in Figure 6, this electrician's wire stripper, comprise pivot pin 3, be installed on the pivot pin on,

lower house

1 and 2, two torsion springs 4, the two ends of torsion spring 4 are respectively with last, lower house 1 contacts with 2, on,

lower house

1 and 2 all is installed with handle 5, last,

lower house

1 and 2 adjacent sides are equipped with axial wire casing, two wire casings are formed the line hole, last, the horizontal cutter fixed head 7 of horizontal cutter fixed head 6 and back before all setting firmly one in the

lower house

1 and 2, the horizontal cutter fixed head 7 adjacent sides of horizontal cutter fixed head 6 and two backs all also are provided with axial wire casing before two, be installed with the radially preceding horizontal blade 8 of cutting edge by screw on the horizontal cutter fixed head 6 before each, be installed with the radially back horizontal blade 9 of cutting edge by screw on each horizontal cutter fixed head 7 in back, last, all be installed with shell fragment 10 on the
