Abstract

The utility model relates to a graver which is composed of a cutter head and a cutter handle, the cutter head is welded with the cutter handle through butt welding, the material rigidity of the cutterhead is higher than that of the cutter handle, and a handle is mounted on the cutter handle. The graver has the beneficial effects that: firstly, the cutter head material has high rigidity, is sharp,wear resistant and durable; secondly, the cutter head only adopts the high rigidity material, the cost is relatively saved in favor of mass production; and thirdly, the cutter heads in different shapes can be machined for different demands.

Description

A kind of graver

Technical field

The utility model relates to the blade field, especially a kind of graver.

Background technology

The cutter head and the handle of a knife of existing graver are structure as a whole, and generally adopt No. 45 common steel, and the edge of a knife wearing and tearing of the graver that this material is made into are very fast, are easy to rust and scrap.Adopt high-quality material as integral body, although durable, cost is higher comparatively speaking, is unfavorable for a large amount of productions.

Summary of the invention

The utility model will solve the shortcoming of above-mentioned prior art, provides a kind of not only durable but also saves the graver of cost.

The utility model solves the technical scheme that its technical problem adopts: this graver, to form by cutter head and handle of a knife, and cutter head is connected in the weld butt welding with handle of a knife, and the material stiffness of cutter head is equipped with handle greater than handle of a knife on the handle of a knife.

As preferably, the cutter head material therefor is a high-speed steel.

As preferably, described cutter head is flat, inclined mouth type or forked formula.

The effect that the utility model is useful is: one, tool tip material rigidity is strong, and is sharp, wear-resisting durable; Two, only adopt the material of high rigidity, saved cost relatively, help a large amount of production at the cutter head place; Three, can produce the various cutter head of shape, adapt to different needs.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the schematic diagram of flat cutter head;

Fig. 3 is the schematic diagram of inclined mouth type cutter head;

Fig. 4 is the schematic diagram of forked formula cutter head;

Description of reference numerals: cutter head 1, handle of a knife 2, weld 3, handle 4.

The specific embodiment

The utility model is described in further detail below in conjunction with accompanying drawing:

Embodiment 1: as Fig. 1, this graver is made up of cutter head 1 and handle of a knife 2, and handle of a knife 2 is No. 45 common steel material, and cutter head 1 adopts high-speed steel (high-speed steel), and cutter head 1 and handle of a knife 2 are connected by butt welding in weld 3.As Fig. 2, cutter head 1 is a flat, and the handle 4 of wooden or plastic or other material is housed on the handle of a knife 2, is convenient to the incised work personnel and uses.

Embodiment 2: difference from Example 1 is that described cutter head adopts inclined mouth type, sees Fig. 3.

Embodiment 3: difference from Example 1 is that described cutter head adopts forked formula, sees Fig. 4.

In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
