According to accompanying drawing the present invention is done detailed explanation below:

Shown in Fig. 1, Fig. 2, wire strippers proposed by the invention mainly by on cut body 4, cut down body 5, shear blade, screw screwdriver bit 9, handle 2 is cut in rotating shaft 3, and insulation handle 1 grade is partly formed, on the upper and lower interior tangent plane of cutting body, have many (this example is four) and the corresponding preformed groove 8 in different size line footpath, two grooves of cutting body are being cut under the body closure state in correspondence with each other, form the small sircle hole of one group of different-diameter.Two angles of cutting the shear blade inclined- plane 10,11 of body and interior tangent plane are less than 90 °, and the latter half of cutting body is a truncation sword 6, and being provided with arc shear blade 7(between truncation sword and preformed groove also can be the dihedral shear blade).Cut the top of body 5 down and make screw screwdriver bit 9.As required, the truncation sword also can be located at preformed groove and cut between the body top.

Wire strippers among Fig. 3, Fig. 4 just has six preformed grooves on the upper and lower interior tangent plane of cutting body, the screw screwdriver bit is not with on its top, makes its structure more simple than example one.

Fig. 5, Fig. 6 illustrate the schematic diagram of the present invention for a kind of pistol-shaped structure, it is provided with the small of the stock 12, annular is cut handle 17, and the upper and lower body of cutting is to be separately fixed at rifle shape matrix 19 and annular is cut on the handle matrix 18 by dog screw 13,14,15,16, and the top of cutting body down is a screw screwdriver bit 9.During use, hand-held gun is cutting handle 17 with finger push-and-pull annular, on cut body around the shaft 3 with cut body generation shear action down.

Wire strippers example shown in Fig. 7, Fig. 8 is that the upper and lower body of cutting is cut handle 20 by U-shaped elasticity and fused, the skin that elasticity is cut handle is that the rear portion that insulating case 21, two is cut body has a spacer 22 respectively, in the use, two spacers are wiped mutually, can prevent that two cut body and misplace when shearing.What this cut two cuts body before use for opening, during operation wire head is put on the corresponding preformed groove shearing edge, make wire head with under cut body and be 20 °～70 ° angles, hold with a firm grip and cut handle, two to cut body closed mutually, shears and surmount, and wire head rubber layer is come off automatically.Unclamp cut handle after the upper and lower body of cutting automatically reset.

Fig. 9 is the example that the present invention makes desk-top wire strippers, and it has base 23, is distributed with positioning screw hole 24 on the base, cuts body base 25 down and fuses with base, also can be the bulk-breaking combination.On cut body base 29 two ends and be equipped with handle 26, the upper and lower body of cutting is the bar blade that at least one end has preformed groove 8 and shear blade, and be fixed on upper and lower cutting on the body base by screw 28 respectively, on cut body by shaft screw 27 with cut the flexible connection of body base and base down.This wire strippers can be provided with single group on the circumference of base 23 or many groups are cut body, has more specification to suit to use in order to the core preformed groove.Figure 10 is that two of Fig. 9 cuts the body vertical view, expresses the preformed groove of cutting body situation and open configuration are set.According to different needs, cut body and cut the body base and also can make an integral body, the preformed groove of tangent plane also can only be opened at one end in cutting body, and the other end is made as the truncation sword.Stand setting if cut the side with two, this wire strippers also can be made into the cutting knife form.

According to wire strippers proposed by the invention, compared with prior art, have significant advantage and multiple function.

1. shear.Hand-held insulation handle 1, handle 2 is cut in opening and closing, can shear dry goods, stationery, insulation cushion and soft core electric wire etc. with truncation sword 6.

2. strip off wire insulation.Make the radially broken skin of cross-shear with 7 pairs of wires to be stripped of arc shear blade, break skin, avulsion insulating barrier with truncation sword 6 along line then.

3. quick wire stripping.Open on the other hand and cut handle, the upper and lower body fork of cutting, another hand is placed on the wire to be stripped head on the core preformed groove 8 that adapts with wire stylet, and selected core preformed groove is a bit larger tham core and less than wire insulation.During placement, wire head with under cut that tangent plane becomes 20 °～70 ° angles in the body, close up and cut handle, the wire to be stripped insulating barrier is cut body preformed groove cutting edge by two and is bitten, on, down cut sword inclined- plane 10,11 give wire insulation sheared edge both direction opposite power respectively, wire head is stressed loses money instead of making money on the core preformed groove, because of lead head insulating barrier weak point, the frictional force of insulating barrier and core is less than the lead other end, so along with last, cutting cutting of body cutting edge down closes, surmount, the insulating barrier of lead head is damaged thereupon, along the slippage of core preformed groove, separate, automatically come off, finish quick wire stripping.

4. loading and unloading screw.With screw screwdriver bit 9, can load and unload the screw on the electrical equipment.
