Abstract

The utility model relates to an electric knife, particularly a knife which can peel off cable skins, comprising a knife housing, a pressing hook, a universal knife, a jacket tube, a spring and a screw nail. The knife head of the universal knife can be rotated, and the height of the knife head is adjusted by the screw nail. A cable is placed between the knife head and the pressing hook, the pressing hook presses the cable tightly, and the knife housing is rotated; the knife head moves in the same direction following the knife head and shears the skins of the cable, then the knife housing move in the direction of the length of the cable, and the moving direction of the knife head is in the direction of the length of the cable. When the knife housing is moved at the needed position, the skins of the cable are stripped off, thus solving the problem that an electrician can not easily strip off the skins of the cable.

Description

Stripper for cable

The utility model relates to a kind of electrician's knife, particularly a kind of can be with the cutter of the quick strip off of cable skin.

What at present the electrician used when cable peeling is common electrician's knife, because the cross-section of cable is circular, and attached cable difficulty when using common electrician's knife peeling, speed is very slow and dangerous, or hand is scratched or cable is cut.

The purpose of this utility model provide a kind of can be with the quick strip off of cable skin, and people and cable all guaranteed safe cable peeling cutter.

The utility model is made up of cutter shell, pressure hook, universal cutter, sleeve pipe, spring and screw.Universal cutter is that so the direction of motion with the cutter shell is consistent all the time for the direction of motion of blade, promptly cutter head can rotate because knife bar and cutter head are not formed on an axis.The knife bar of universal cutter is inserted in sleeve pipe and the spring, and sleeve pipe is fixed on the cutter shell.Knife bar can rotate in sleeve pipe or slide.One end of spring withstands sleeve pipe, and the other end withstands the knife bar bottom, makes knife bar not break away from sleeve pipe.Universal cutter withstands the knife bar bottom by screw and makes the cutter head fixed-site, and the advance and retreat of set screw can change the height of cutter head, and cutter head can change by the force direction that is subjected to the cutter shell in circular hole.On pressure hook, it is strained, so that cable is compressed with spring.When the stripping cable skin, elder generation's set screw makes cutter head reach desired height, cable is put between cutter head and the pressure hook, at this moment pressure hook is pushed down cable, the cutter shell is rotated along the circular arc direction of cable, and cutter head also rotates together and cable skin is cut, and the cutter shell is moved along the cable length direction again, at this moment the cutter head of universal cutter changes with the stressed change of cutter shell, simultaneously also with the cable skin strip off.

The utility model improves the speed of cable peeling by the ingenious combination of cutter shell, pressure hook, universal cutter, spring and screw greatly, and all safe and reliable to people and cable.

Be described further below in conjunction with accompanying drawing 1,2.

Fig. 1 is a cable peeling cutter elevation cross-sectional view,

Fig. 2 is a cable peeling cutter side cutaway view.

When using the cable peeling cutter, first set screw 7 makes cutter head 2 reach desired height.Form universal cutter by on an axis cutter head 2 and knife bar 3 not, the direction of motion of cutter head 2 direction of motion with cutter shell 8 all the time is consistent.Knife bar 3 is inserted in sleeve pipe 11 and the spring 5, and sleeve pipe 11 is fixed on the cutter shell 8 by screw 12.One end of spring 5 withstands sleeve pipe 11, and the other end withstands on the bottom of knife bar 3.When screw 7 withdraws from certain distance downwards, knife bar 3 descends under the effect of spring 5 cutter head is fallen back in the cutter shell 8, and upwards jacking certain distance, knife bar 3 rise cutter head 2 spring 5 compressions under the effect of screw 7 promptly to reach the purpose of regulating cutter head 2 when screw 7.Pressure hook 1 is fixed on the cutter shell 8 by screw 6 by spring 4 pullings, spring 4.Cable 9 is placed between cutter head and the pressure hook 1, and at this moment pressure hook compresses cable 9, and cutter shell 8 is rotated along cable 9, and cutter head 2 also equidirectional rotations this moment are also cut cable skin.Again cutter shell 8 is moved along cable 9 length directions, at this moment universal cutter is owing to be subjected to the change of force direction, and the direction of motion of cutter head 2 becomes along the length direction of cable 9 with cutter shell 8, and cutter head 2 is to rotate to change direction in circular hole 10, when cutter shell 8 moved to desired location, cable skin is strip off simultaneously also.

Claims

1, a kind of cable peeling cutter of being made up of cutter shell 8, cutter head 2, spring 4, screw 7 is characterized in that pressure hook 1 is by spring 4 pullings.

2,, it is characterized in that cutter head 2 and knife bar 3 not on an axis by the described cable peeling cutter of claim 1.

3, by the described cable peeling cutter of claim 1, it is characterized in that the bottom of cutter shell 8 is provided with screw 7.
