Abstract
The utility model relates to a large-diameter circular paper knife, which consists of a knife body, a knife point and a positioning hole, wherein the positioning hole is arranged at the center of the paper knife, and is characterized in that a side clearance angle is arranged between the knife point and the knife body, and the knife body outside the positioning hole is provided with a transmission hole and a threaded knife fetching hole. The side clearance angle is from 11 to 15 degrees. The rigidness of the paper knife with the same thickness can be increased, the application quantity of the steel material can be reduced, and the raw material can be saved; and the paper knife can be conveniently replaced.
Description
Technical field
The utility model belongs to the cutting tool field, especially a kind of major diameter hand papercutter that uses man-hour that adds in paper product.
Background technology
At present, justify hand papercutter and be widely used in cutting processing in the productions such as paper, books and papery packing.
In the prior art, all the size that whole blade requires according to hand papercutter in the making of circle hand papercutter, blade begins to reduce blade thickness gradually until point of a knife with certain side clearance angle from locating hole, make at making major diameter hand papercutter blade not enough in the very thin thickness rigidity at point of a knife place, easy to wear in use, reduce its service life, increased steel using amount again greatly, be unfavorable for economizing on resources as the hardness that increases the hand papercutter blade; The circle hand papercutter is that a kind of circle is driven cutting edge of a knife or a sword formula cutter, and periphery all is sharp point of a knife, easily operation is produced injury when changing.
Summary of the invention
For overcoming this defective of the prior art, on the basis of the existing circle of the utility model hand papercutter, increase the angle of the side clearance of point of a knife, keep blade at thickness near the point of a knife place; Get and install screw on the tool bore and be convenient for changing hand papercutter setting up screw thread on the blade.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of major diameter circle hand papercutter, form by blade, point of a knife and locating hole, locating hole is positioned at the hand papercutter center, it is characterized in that: described point of a knife and blade have side clearance, and blade is provided with driving hole outside the locating hole, screw thread is got tool bore.
The angle of described side clearance is between 11-15 °.
The beneficial effects of the utility model are the rigidity that can increase the same thickness hand papercutter, have reduced the use amount of steel, save material; Be convenient for changing hand papercutter.
