Abstract
The invention relates to a double-blade straight-flute ball-end sharp knife, comprising a sharp knife body and a knife sheath, wherein the knife sheath is movably clamped with the sharp knife body; two pairs of clamping slots are arranged on the wall at one end of the knife sheath; one end of the sharp knife body is a knife handle; the other end of the sharp knife body is a cutting part; the tail end of the knife handle is provided with a rotary shaft which is corresponding to the clamping slots; the cutting part is provided with two symmetrically arranged chip grooves; each of the chip grooves is formed by two groove walls; the first groove wall of each chip groove is a plane, and the second groove wall of each chip groove is formed by a plane and a cambered surface; the front end of the cutting part is formed conically. By utilization of the scheme, the chip grooves are arranged on the cutting part, and the front end of the cutting part is formed conically, so that chips are more conveniently discharged; when the sharp knife is not in use, the knife sheath sleeves the sharp knife, and is clamped with the rotary shaft, so that the sharp knife is protected; when the sharp knife is in use, the knife sheath is clamped on the tail end of the knife handle of the sharp knife, so that the length of the knife handle can be increased, and a user more conveniently uses the sharp knife.
Description
Technical field
The present invention relates to a kind of graver, be specifically related to a kind of twolip straight trough bulb sharp knife.
Background technology
Graver handle of a knife is shorter than cutting portion, and user uses inconvenience, in addition, the unshielded structure of graver, when not using, easily impaired or cause damage to external world, such as, scratch clothes, scratch skin.
Summary of the invention
For the problems referred to above, the object of this invention is to provide a kind of twolip straight trough bulb sharp knife.
Realize technical scheme of the present invention as follows:
Twolip straight trough bulb sharp knife, comprise sharp knife body, with the broach shell of sharp knife body activity clamping, the wall of one end of broach shell is provided with two pairs of draw-in grooves; One end of described sharp knife body is handle of a knife, the other end is cutting portion, the end of described handle of a knife is provided with the rotating shaft corresponding with draw-in groove, described cutting portion is provided with two symmetrically arranged chip areas, described chip area is made up of two cell walls, wherein the first cell wall is plane, and the second cell wall is made up of plane and cambered surface, and the nose circle taper of cutting portion is arranged.
Further, described broach shell is for having cavity and one end is packing less cylindrical, and described draw-in groove is arranged on untight one end, and the cavity inside diameter size of broach shell corresponds to sharp knife body diameter.
Further, described shaft length corresponds to broach shell external diameter size.
Have employed above-mentioned scheme, the setting of cutting portion chip area and its front end are conical setting, make chip removal more convenient; When not using sharp knife, broach shell is placed on sharp knife, and with rotating shaft clamping, play protection sharp knife, during use, broach shell is connected to the handle of a knife end of sharp knife, can extend shank length, and user has used sharp knife convenient.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the invention will be further described.
See Fig. 1 ~ 6, twolip straight trough bulb sharp knife, comprise sharp knife body, with the broach shell 7 of sharp knife body activity clamping, the wall of one end of broach shell is provided with two pairs of draw-in grooves; One end of described sharp knife body is handle of a knife 1, the other end is cutting portion 2, the end of described handle of a knife is provided with the rotating shaft 6 corresponding with draw-in groove, described cutting portion is provided with two symmetrically arranged chip areas, described chip area is made up of two cell walls, wherein the first cell wall 4 is plane, and the second cell wall 5 is made up of plane 10 and cambered surface 11, and the nose circle taper of cutting portion is arranged.
Further, described broach shell is for having cavity and one end is packing less cylindrical, and described draw-in groove is arranged on untight one end, and the cavity inside diameter size of broach shell corresponds to sharp knife body diameter.
Further, described shaft length corresponds to broach shell external diameter size.
See Fig. 2,3,4, during use, broach shell is directly connected with handle of a knife, rotating shaft two ends is aimed at first pair of draw-in groove 8 of broach shell, rotating shaft and first pair of draw-in groove rotary clamping, because broach shell has cavity, now, broach shell and sharp knife coaxial line, part handle of a knife is placed in cavity, broach shell and sharp knife are connected together and extend the hand-held length of sharp knife, and user is more convenient to use.Described first pair of draw-in groove is bending to be arranged, and guarantees that the two ends of rotating shaft are connected in first pair of draw-in groove.First pair of draw-in groove is not limited to the structure described in the present invention, as long as can realize the two ends of rotating shaft and the clamping of first pair of draw-in groove.
See Fig. 2,3,5, when not using, broach shell is set on sharp knife from cutting portion; until second pair of draw-in groove 9 and rotating shaft two ends are connected together, described second pair of draw-in groove is deep-slotted chip breaker, now; sharp knife is placed in broach shell, the damage both having protected sharp knife to turn avoid sharp knife may to cause to external world.
The setting of cutting portion chip area of the present invention and the setting of cone-shaped nose 3, make chip removal more convenient.Sharp knife grinds through high accuracy, and processing effect is splendid.
The present invention is not limited to described embodiment, and those skilled in the art, not departing from spirit of the present invention namely openly in scope, still can do some and revise or change, therefore the scope that the scope of the present invention limits with claims is as the criterion.
