Description
The utility model relates to electrician's instrument.
Electrician's instrument screwdriver that generally use present market is made up of handle of a knife and cutter hub, and cutter hub top is set in the handle of a knife, and the middle part is that cylinder is exposed outside, and the bottom is two flat bodily forms of Dou face, and the top is that prolate is square, can insert in the screw elongated slot and rotate.When the electrician operates, generally have screwdriver, wire stripper, nipper plier, wire stripper are used for peelling off the plastic foreskin of wire end, and nipper plier is in order to the line stamen of crooked the end of a thread, particularly rigid line head, make it to bend to " U " font, so that screw has passed securing electric lines head line stamen, then use the screwdriver rotary screw with link again, like this maneuver, instrument is various, inconvenient operation.
The purpose of this utility model is to overcome above-mentioned defective, provides a kind of wire stripping, curved line, rotation three to use screwdriver.
Scheme of the present utility model is: two flat body one sides of Dou face in cutter hub bottom have breach, and the breach center line is angled with two flat body median planes of Dou face, and the width of breach and depth ratio electric wire outside dimension commonly used is bigger.
Advantage of the present utility model is that Dou body breach and the flat body on the two flat bodies of Dou face of screwdriver constitutes two-way blade, can be used for wire stripping, and wire range is big, and Dou body breach can also be in order to bending line, thereby reach a cutter three usefulness, and is easy to operate.
Accompanying drawing 1 is a cutter hub bottom front view.
Accompanying drawing 2 is a cutter hub bottom vertical view.
The utility model is to implement like this: screwdriver is made up of handle of a knife and cutter hub, and cutter hub top is set in the handle of a knife, and the middle part is that cylinder is exposed outside, and the bottom is two flat bodily forms of Dou face, and the top is that prolate is square, can insert in the screw elongated slot and rotate.Two flat body one examples of Dou face in cutter hub bottom have breach, and the breach center line is angled with two flat body median planes of Dou face, and the width of breach and depth ratio electric wire outside dimension commonly used is bigger.The breach center line is good at 30 degree to 60 degree scopes generally with the angle of two flat body median planes of Dou face, make the breach and the Dou face of two flat bodies of Dou face form two cutting edges, cutting edge is not only wanted sharp but also certain intensity is arranged, angle is too little, cutting edge is sharp but the little wire stripping of intensity is might be turned, this angle is too big, and then blade is not sharp, the wire stripping difficulty.The gap width and the degree of depth are good with two to five millimeters.
During use, the end of a thread is put into breach, again with angle of screwdriver rotation, two relative blades on the breach are just cut in the lead plastic skin of the end of a thread both sides, the anglec of rotation is big more, and the blade incision plastic skin degree of depth is just dark more, firmly the end of a thread is drawn back along the end of a thread center line is relative with screwdriver again, the plastic skin that is stuck by blade on the end of a thread just is stripped from, and exposes the line stamen.If when wanting the line stamen on crooked the end of a thread, as long as the screwdriver breach is snapped in the line stamen, catch the end of a thread root on the other hand, be center of circle rotary screw cutter again with the breach on the other hand, the line stamen just can be crooked.
Screwdriver one cutter three usefulness like this, instrument is simplified in electrician's operation, and is easy to operate.
