In order to guarantee being connected firmly of handle of a knife and cutter head, increase the service life, said handle of a knife and said cutter head are one-body molded.

For the ease of handle of a knife fixing on lathe, the cross section of said handle of a knife is a rectangle.The front and back sides of said handle of a knife respectively is provided with two holddown grooves.

In order to guarantee the work safety of cutter head, said cutter head is cylindrical, and the diameter of cutter head is less than the diameter of handle of a knife.

The invention has the beneficial effects as follows: square groove cutting knife provided by the invention, simple in structure, cost is low, and is easy to use, and high efficiency is fit to small-scale production or processes exemplar.And, said square groove cutting knife convenient fixing, long service life, easy to utilize.

Description of drawings

Fig. 1 is the structural representation of square groove cutting knife of the present invention.

The main mark implication is following in the accompanying drawing:

1, handle of a knife 2, cutter head 3, blade 4, groove 5, holddown groove.

The specific embodiment

Below in conjunction with accompanying drawing and specific embodiment the present invention is done concrete introduction.

As shown in Figure 1: a kind of square groove cutting knife comprises handle of a knife 1, cutter head 2 and blade 3.

The cross section of said handle of a knife 1 is a rectangle, and front and back sides respectively is provided with two holddown grooves 5, is convenient to handle of a knife 1 firm being fixed on the lathe prevented that the square groove cutting knife from rocking in the course of the work.

Said cutter head 2 bottoms are connected with said handle of a knife 1, and said cutter head 2 tops have a groove 4, and said blade 3 is fixed in the said groove 4.In the present embodiment, said cutter head 2 is cylindrical, and the diameter of cutter head 2 is less than the diameter of handle of a knife 1.

And said handle of a knife 1 and said cutter head 2 are one-body molded, guarantee being connected firmly of handle of a knife 1 and cutter head 2, prolong its service life.

Square groove cutting knife provided by the invention, simple in structure, cost is low, and is easy to use, and high efficiency is fit to small-scale production or processes exemplar.

The foregoing description does not limit the present invention in any form, and all employings are equal to the technical scheme that mode obtained of replacement or equivalent transformation, all drop in protection scope of the present invention.
