The width of described cutter head is 2～3mm and angle between blade and the horizontal plane of cutter head is 45 °～60 ° when cutter head is vertical state.
Use between described handle of a knife with cutter neck and threaded.
Described cutter neck includes operate neck and auxiliary cutter neck, is connected with operator neck in the tail end of cutter head embeds auxiliary cutter neck and by auxiliary cutter neck, and operator neck is directly anchored to the front end of handle of a knife.
The diameter of described operator neck is more than the diameter of auxiliary cutter neck.
Described handle of a knife uses hollow steel pipe to make.
Described cutter head uses wolfram steel material to make and the tangent plane of the blade of cutter head and blade periphery smooths.
This utility model has the following advantages compared to existing technology:
This utility model is by limiting handle of a knife and the diameter of cutter neck so that it is do not affects the visual field under microscope during use, the most affect the hands assurance to cutter；Handle of a knife entirety is all steel matter, and after cutter head and cutter neck connect, cutter neck is connected by screw thread and handle of a knife, connects more firm, solve plastic knife handle to be easily broken off, the problem easily rived in handle of a knife and cutter head junction, the most threaded makes convenient disassembly between cutter neck and handle of a knife, it is simple to change cutter head.
Handle of a knife of the present utility model is hollow steel pipe, it is possible to saving material, quality is light and handy, it is also possible to Reusability；And cutter head when being disposed vertically angle between blade and the horizontal plane of cutter head be 45 °～60 °, the problem solving cutting bad to ovum under the microscope, cutter head uses wolfram steel material, it is ensured that will not bend when operation；Overall structure firmly, light and handy, convenient and handle of a knife can Reusability, cutter head is replaceable, it is possible to save resource, and simple in construction, easy to operate, suitably promotes the use of.
Accompanying drawing explanation
Accompanying drawing 1 cuts one of ovum knife structure schematic diagram for Novel handcraft of the present utility model；
Accompanying drawing 2 is that Novel handcraft of the present utility model cuts the two of ovum knife structure schematic diagram.
Wherein: 1 handle of a knife；2 cutter necks；21 operator necks；22 auxiliary cutter necks；3 cutter heads.
Detailed description of the invention
With embodiment, this utility model is further described below in conjunction with the accompanying drawings.
As shown in Fig. 1～2: a kind of Novel handcraft cuts ovum cutter, including handle of a knife 1, cutter neck 2 and cutter head 3, wherein handle of a knife 1 uses hollow steel pipe to make, the width of cutter head 3 is 2～3mm and angle between blade and the horizontal plane of cutter head 3 is 45 °～60 ° when cutter head 3 is in vertical state, and cutter head 3 uses wolfram steel material to make and the tangent plane of the blade of cutter head 3 and blade periphery smooths；For structure, cutter head 3 is fixedly mounted on cutter neck 2, and the tail end of cutter neck 2 is fixedly connected on the front end of handle of a knife 1, uses and threaded between handle of a knife 1 with cutter neck 2, the diameter of handle of a knife 1 and cutter neck 2 be all 2～5mm and the diameter of handle of a knife 1 more than the diameter of cutter neck 2.
On the basis of said structure, in order to preferably optimize this attachment structure cutting ovum cutter, cutter neck 2 includes operate neck 21 and auxiliary cutter neck 22, it is connected with operator neck 21 in the tail end of cutter head 3 embeds auxiliary cutter neck 22 and by auxiliary cutter neck 22, operator neck 21 is directly anchored to the front end of handle of a knife 1, and the diameter of described operator neck 21 is more than the diameter of auxiliary cutter neck 22.
