Abstract

The utility model relates to a paper cutter which comprises an upper cutter and a lower cutter which mutually shear, wherein the upper cutter comprises an upper cutter body part and an upper cuter blade part positioned at the lower end of the upper cutter body part, the lower cutter comprises a lower cutter body part and a lower cutter blade part positioned at the upper end or lower end or the upper end and the lower end of the lower cutter body part, and the sections of the upper cutter body part and the lower cutter body part are concave. The upper cutter body part and the lower cutter body part are concave, thus the strength of the cutter bodies can be improved, and the thickness of a cutter body material is reduced; during cutting, the blade parts can not be in contact with the cutter body parts to damage blades, thus an upper blade and a lower blade are always kept to be sharp and the cutting effect is good. The blade parts are arranged at the upper end and the lower end of the lower cutter body part, and the cutter blades can be replaced for use.

Description

Hand papercutter
Technical field
The utility model relates to a kind of hand papercutter, relates in particular to the improvement of cut-off knife up and down wherein.
Background technology
Hand papercutter comprises the workbench of placing paper-cut to be cut, the lower cut-off knife (or weighed cutter) that is fixed in workbench one side end face and upper cut-off knife (or claiming cutting knife), upper cut-off knife one end is with together with lower cut-off knife one end is rotatably connected, the blade of upper and lower cut-off knife is relative, by the relative shear campaign of upper and lower cut-off knife, carries out cutting of paper.The cutter hub of the cut-off knife up and down of the hand papercutter used at present is blocked up, is the 6-10 millimeter, and can produce swing during cut paper, needs often to correct the impetus of cut-off knife.In addition, while cutting, two cut-off knife contact-making surfaces are excessive, and blade part easily weares and teares, and affects the service life of cut-off knife.
Summary of the invention
Technical problem to be solved in the utility model is: the cut-off knife up and down to existing hand papercutter is improved, and a kind of cutter hub thinner thickness is provided, not easy to wear, cuts the hand papercutter of better effects if.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of hand papercutter, the upper cut-off knife and the lower cut-off knife that comprise mutual shearing, the upper cut-off knife blade part that described upper cut-off knife comprises cut-off knife cutter hub section and is positioned at cut-off knife cutter hub subordinate end, described lower cut-off knife comprises lower cut-off knife cutter hub section and is positioned at lower cut-off knife cutter hub section upper end or the lower cut-off knife blade part at lower end or upper and lower two ends, and the cross sectional shape of described upper cut-off knife cutter hub section and lower cut-off knife cutter hub section is concave shape.
Adopt technique scheme can realize following technique effect: 1, the cutter hub of upper cut-off knife and lower cut-off knife partly to be set to concave shape, the intensity (concave shape has the effect of reinforcement) of cutter hub can be strengthened, and the thickness (thickness can be reduced to the 1-3.5 millimeter) of cutter hub material can be reduced; While cutting, blade part can not contact with cutter hub section and damage blade, remains upper and lower keen edge, cuts effectively, and operates free and relaxed.2, at the upper and lower two ends of the cutter hub of lower cut-off knife, blade part is set, a cutter hub has the two sides blade, after wherein a blade weares and teares, another blade can be changed to use, does not need to upgrade in addition lower cut-off knife, and then reduces the cost of charp tool.This upper and lower cut-off knife goes for manually or electric paper cutting knife.
Below in conjunction with drawings and Examples, technology contents of the present utility model is described further.
