As further scheme of the invention, trapezoidal portion and the stream smooth connection in bits portion of first machining position, and described the The trapezoidal portion of one machining position has radian with the junction in stream bits portion.

Used as further scheme of the invention, trapezoidal portion and the junction in stream bits portion of second machining position have knuckle Position.

Used as further scheme of the invention, the stream bits portion level is downward.

Beneficial effect of the present invention produced by compared with background technology：

Present invention employs such scheme, it is set to there is simple structure, coordinate compact, it is easy to use, it is reasonable in design, it is elegant in appearance The advantages of, smooth design can keep the smoothness of as-machined workpiece surface, improve the quality of product；It is a kind of technical and warp Ji property is respectively provided with the product of superior function.

【Brief description of the drawings】

Fig. 1 is the graver schematic perspective view in preferred embodiment provided by the present invention；

Fig. 2 is the graver structural representation in preferred embodiment provided by the present invention.

【Specific embodiment】

Embodiments of the invention are described below in detail, described embodiment example is shown in the drawings, wherein identical from start to finish Or similar label represents same or similar element or the element with same or like function.

In the description of the invention, it is necessary to illustrate, for the noun of locality, if any term " " center ", " transverse direction（X）” 、 " longitudinal direction（Y）", it is " vertical（Z）" " length ", " width ", " thickness ", " on ", D score, "front", "rear", "left", "right", " vertical ", The indicating position such as " level ", " top ", " bottom ", " interior ", " outward ", " clockwise ", " counterclockwise " and position relationship are based on accompanying drawing institute The orientation or position relationship for showing, are for only for ease of the narration present invention and simplify description, rather than the dress for indicating or implying meaning Put or element there must be specific orientation, be constructed and operated with particular orientation, it is impossible to be interpreted as limitation specific guarantor of the invention Shield scope.

Additionally, be only used for describing purpose if any term " first ", " second ", and it is not intended that indicating or implying relatively heavy The property wanted or the implicit quantity for indicating technical characteristic.Thus, defining " first ", " second " feature can express or implicit include One or more this feature, in the present description, " several " are meant that two or more, unless otherwise clearly having The restriction of body.

In the present invention, except as otherwise clear stipulaties and restriction, should make if any term " assembling ", " connected ", " connection " term Broad sense is gone to understand, for example, it may be being fixedly connected, or being detachably connected, or is integrally connected；Can also be that machinery connects Connect；Can be joined directly together, or be connected by intermediary, can be that two element internals are connected.For ability For the those of ordinary skill of domain, above-mentioned term concrete meaning in the present invention can be as the case may be understood.

In invention, unless otherwise prescribed and limit, fisrt feature second feature it " on " or D score can include First and second feature directly contacts, it is also possible to including fisrt feature and second feature be not directly contact but by them it Between other characterisation contact.And, fisrt feature includes fisrt feature the in second feature " on ", " under " and " above " Directly over two features and oblique upper, or be only to represent height of the fisrt feature level height higher than second feature.Fisrt feature Include fisrt feature immediately below second feature or obliquely downward in second feature " on ", " under " and " below ", or only table Show that fisrt feature level height is less than second feature.

With reference to the accompanying drawing of specification, it is further described by specific embodiment of the invention, sends out this Bright technical scheme and its advantage is clearer, clear and definite.It is exemplary, purport below with reference to Description of Drawings embodiment It is of the invention explaining, and be not considered as limiting the invention.

The preferred embodiment that the present invention is provided：As depicted in figs. 1 and 2, a kind of graver, including cutter hub 10, the cutter hub 10 are provided with cutting head 20 and chip removal portion 30.

The cutting head 20 has trapezoidal portion 40 and stream bits portion 50；The level of stream bits portion 40 downwards, tiltedly under stream bits portion 40 reserve space, facilitate the waste material that cutting head 20 is cut to be discharged outside cutter hub 10 along stream bits portion 50.
