Abstract

The utility model belongs to the technical field of cutting tools, particularly relates to a high-speed steel knife for mending a fishnet. The high-speed steel knife comprises a cutting head and a knife handle which is formed at the tail part of the cutting head through injection molding, and the bottom of the joint end of the tail part of the cutting head and the knife handle is outwardly provided with bulges for increasing the connection fastness of the cutting head and the knife handle. According to the utility model, the tail part of the cutting head is provided with sawtooth-shaped bulges, hook-shaped bulges or bulges with other shapes, the knife handle is directly formed on the cutting head in an injection molding manner by an injection molding machine, the bulges and the knife handle are combined completely, the connection among the bulges and the knife handle is firmer, and therefore, the high-speed steel knife is long in service life, the connection between the cutting head and the knife handle cannot be loosened, or the cutting head cannot slip off from the knife handle after long-time use. The knife handle is made of a nylon material, cannot be corroded after being immersed in water or affected with water for a long time, and cannot rupture after long-time use. The high-speed steel knife is suitable for fishnet mending.

Description

A kind of high-speed steel is caught the net cutter

Technical field:

The utility model belongs to the cutting-tool engineering field, refers in particular to a kind of high-speed steel and catches the net cutter.

Background technology:

Catch the net cutter and be fisherman and wait the instrument of the usefulness that is used for mending fishing nets.Structure of catching the net cutter of the prior art is generally: an end of cutter head is connected with handle of a knife through pin.The net cutter of catching of this structure exists following weak point: the one: connect insecure; Owing in use need use bigger power; Catch the net cutter after using the long period, loosening easily between handle of a knife and the cutter head, even cutter head comes off from handle of a knife; Service life is short, and also the fisherman also brings great inconvenience simultaneously; The 2nd: generally use handle of a knife to adopt wood material to process at present, the consumption of timber need be fallen trees, and is unfavorable for environmental protection, simultaneously, in long-term use, occurs the situation of handle of a knife corrosion even fracture easily.

Summary of the invention:

The purpose of the utility model provides and a kind ofly is connected firmly, the high-speed steel of long service life is caught the net cutter.

The utility model is achieved in that

A kind of high-speed steel is caught the net cutter, includes cutter head and handle of a knife, and the afterbody injection mo(u)lding of described cutter head has handle of a knife, and the bottom surface of the afterbody of cutter head and handle of a knife binding end is to being outside equipped with to increase cutter head is connected fastness with handle of a knife convexity.

Above-mentioned convexity is serrate projections or square convexity or wavy bulge or the convexity of colluding shape.

Above-mentioned handle of a knife is processed with nylon material.

The utility model is compared the outstanding advantage of prior art:

1, the afterbody of the cutter head of the utility model convexities such as convexity that are provided with serrate projections or collude shape; Handle of a knife is direct and cutter head injection mo(u)lding through injection machine; Fully combine between convexity and the handle of a knife, being connected between convexity and the handle of a knife is more firm, long service life; The long-term use can not make between cutter head and the handle of a knife landing from the handle of a knife of loosening or cutter head yet;

2, the handle of a knife of the utility model adopts nylon material to process, and does not corrode behind immersion for a long time or the chance water, does not rupture after long-term the use;

3, the utility model is convenient for production, has avoided loaded down with trivial details between cutter head and the handle of a knife and has been connected technology, directly injection mo(u)lding.

Description of drawings:

Fig. 1 is the schematic perspective view of the utility model;

Fig. 2 be the utility model the afterbody of cutter head be the sketch map of serrate projections.

The specific embodiment:

With specific embodiment the utility model is further described below, referring to Fig. 1-2:

A kind of high-speed steel is caught the net cutter, includes cutter head 10 and handle of a knife 20, and the afterbody injection mo(u)lding of described cutter head 10 has handle of a knife 20, and the bottom surface of the afterbody of cutter head 10 and handle of a knife 20 binding ends is to being outside equipped with to increase cutter head is connected fastness with handle of a knife convexity 101.Protruding 101 combine with handle of a knife 20, use for a long time, and cutter head 10 can not come off from handle of a knife 20 yet.

Above-mentioned convexity 101 is serrate projections or square convexity or wavy bulge or the convexity of colluding shape.Because handle of a knife 20 101 fully combines with convexity, cutter head 10 can not come off and influences use from handle of a knife 20.

Above-mentioned handle of a knife 20 usefulness nylon materials are processed.The material that handle of a knife 20 also can adopt nylon to mix with plastics is processed, and intensity is high, and is not easily broken.

The utility model is applicable to the occasion that mends fishing nets, and cutter head 10 is connected firmly long service life with handle of a knife 20.

The foregoing description is merely one of preferred embodiment of the utility model; It is not the practical range that limits the utility model with this; So: the equivalence that all shapes according to the utility model, structure, principle are done changes, and all should be covered by within the protection domain of the utility model.

Claims

1. a high-speed steel is caught the net cutter, includes cutter head and handle of a knife, it is characterized in that: the afterbody injection mo(u)lding of described cutter head has handle of a knife, and the bottom surface of the afterbody of cutter head and handle of a knife binding end is to being outside equipped with to increase cutter head is connected fastness with handle of a knife convexity.

2. a kind of high-speed steel according to claim 1 is caught the net cutter, it is characterized in that: described convexity is serrate projections or square convexity or wavy bulge or the convexity of colluding shape.
