Abstract

The utility model discloses a novel wire-stripping cutter. The novel wire-stripping cutter comprises an L-shaped cutter, wherein a cutter point is formed at the front end of the short arm of the L-shaped cutter, and a protection boss is arranged at the lower end of the short arm of the L-shaped cutter; the cutter point at the front end of the L-shaped cutter directly cuts an insulated layer, the protection boss at the lower end of the L-shaped cutter is pressed on a conductor, thus a clearance is reserved between the cutter point and the conductor so that the conductor is prevented from being damaged by the cutter point. The novel wire-stripping cutter is not only suitable for the existing wire stripping machine, but also suitable for tools such as wire-stripping pliers.

Description

Novel wire stripping cutter

Technical field

The utility model relates to a kind of novel wire stripping cutter, belongs to the stripping tool technical field.

Background technology

Along with being widely used of electric wire, and in the daily installation of electric wire, repair procedures, often need the insulation sheath of electric wire be peeled off, and in the production process, the substandard product of generation also need be peeled off out with metallic conductor.

Various wire strippers in the market, wire stripping pliers are used cutter; A kind of is to utilize outside blade vertically crushes electric wire, and another is all to be to utilize narrow blade passage that electric wire insulation layer is wiped off, and the former in use grasps and badly just can occur cannot not pressing brokenly or conductor is pressed into broken section situation; Cause the situation of peeling off inconvenience; And the latter is owing to be that insulation is scraped off by force, and can receive very big resistance, uses comparatively hard.

The utility model content

The utility model is intended to provide a kind of conductor, easy to use and be applicable to the novel wire stripper cutter of existing wire stripper, wire stripping pliers that do not damage.

The purpose of the utility model can reach through following measure: a kind of novel wire stripping cutter; Comprise the tool rest spring is installed on tool rest, the tool rest; Said tool rest lower end is connected with L shaped cutter, and the galianconism front end of L shaped cutter is a point of a knife, and the galianconism lower end of L shaped cutter is the protection boss.

The technique scheme difference with the prior art is: the disclosed novel wire stripping cutter of the utility model; Wherein, The point of a knife of L shaped cutter front end directly cuts insulating barrier; L shaped cutter lower end has the protection boss to make and to leave the gap between point of a knife and the conductor by being pressed on the conductor, prevents point of a knife damage conductor.

Further, in order to mate the wire stripper upper hopper chute, said L shaped cutter is connected with tool rest through bolt.

Further, the probability of point of a knife fracture when reducing work, the blade of said point of a knife faces up.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is done further detailed explanation:

Fig. 1 is the structural representation of existing wire stripping cutter embodiment 1;

Fig. 2 is the structural representation of existing wire stripping cutter embodiment 2;

Fig. 3 is the structural representation of novel wire stripping cutter embodiment;

Fig. 4 is along the sectional structure sketch map of A-A line among this Fig. 3;

Fig. 5 is the amplification knot sketch map of a part among Fig. 4.

Embodiment

See figures.1.and.2, Fig. 1 and Fig. 2 are existing cutter pattern, comprise sword wheel 101 among Fig. 1, and sword wheel capable of using 101 crushes electric wire, but the conductor of easy damaged electric wire; Fig. 2 utilizes narrow band sword through hole 201 to peel off insulating barrier or other top layers by force, can receive very big resistance, uses comparatively hard.

With reference to Fig. 3, Fig. 4 and Fig. 5,, comprise tool rest 1, L shaped cutter 3 for the utility model is a kind of novel wire stripping cutter; Tool rest spring 2 is installed on the tool rest 1; The below of L shaped cutter 3 corresponding place the chute 4 of electric wire, the long-armed of L shaped cutter 3 is connected in the middle of tool rest 1 lower end through bolt, the galianconism front end of L shaped cutter 3 is a point of a knife 31; The blade of point of a knife 31 faces up, and the galianconism lower end of L shaped cutter 3 is protection boss 32.

During use, this wire stripping cutter is installed on the wire stripper, during wire stripping, point of a knife 31 scratches the insulating barrier of electric wire, exposes the conductor of electric wire, and protection boss 32 contacts with conductor, presses conductor, prevents that point of a knife 31 from scratching conductor.

Above-described only is the preferred implementation of the utility model, and the utility model both had been applicable to existing wire stripper, also was applicable to instruments such as wire stripping pliers; Should be understood that; For a person skilled in the art, under the prerequisite that does not break away from the utility model structure, can also make some distortion and improvement; These also should be regarded as the protection range of the utility model, and these can not influence effect and practical applicability that the utility model is implemented.

Claims

1. a novel wire stripping cutter comprises the tool rest spring is installed on tool rest, the tool rest, and it is characterized in that: said tool rest lower end is connected with L shaped cutter, and the galianconism front end of L shaped cutter is a point of a knife, and the galianconism lower end of L shaped cutter is the protection boss.

2. a kind of novel wire stripping cutter according to claim 1 is characterized in that: said L shaped cutter is connected with tool rest through bolt.

3. a kind of novel wire stripping cutter according to claim 1, it is characterized in that: the blade of said point of a knife faces up.
