Description
Technical field
The utility model relates to a kind of tack semicircle chisel.
Background technology
Chisel is a kind of speciality cutter that the craftsman master workers often use when being used for chiseling and carving the handicraft of materials such as various wooden, beautiful matter, Shi Zhi.Present chisel generally comprises handle and blade, and the afterbody and the handle of said blade are fixed, and the head of said blade is a cutter head, and the cross section of this blade is rectangular, and cutter head comprises blade and cutting edge.It is not enough below the chisel of above prior art exists: because cutter head is generally the plane; Like this can only processing plane, if run into the shape (like the chamfering of right angle, arc, plane groove, arc groove and different shape etc.) of processing varying cross-section, then can't one-shot forming processing; Can only process several times with chisel; And the shape that processes is difficult for satisfying normal requirement, and also being simultaneously increases process time, makes processing time-consuming.
The utility model content
The technical problem that the utility model will solve is, provide a kind of for specific cross section can straight forming processing, saving of labor's tack semicircle chisel of saving trouble.
The technical scheme of the utility model is, a kind of tack semicircle chisel with following structure is provided, and comprises handle and blade, and the afterbody and the handle of said blade are fixed, and the head of said blade is a cutter head, and said cutter head comprises blade and cutting edge; The afterbody of said blade is embedded in the handle middle part; The cross section of said cutter head is curved, and said blade is positioned at the lateral surface of cutter head.
Go back close-fitting on the afterbody of said blade and the handle the radially bearing pin that is connected both is arranged.
After adopting above structure, the utility model compared with prior art has the following advantages: because the afterbody of said blade is embedded in the handle middle part; Make blade be difficult for from handle, coming off like this; The cross section of said cutter head is curved, and said blade is positioned at the lateral surface of cutter head, can process the surface of sphere, cambered surface or cylinder etc. like this; Be one-shot forming processing, make the processing time and labour saving.
