Description
Technical field
The utility model relates to a kind of novel pencil sharpener that is used to sharpen a pencil, and belongs to the schooling apparatus technical field.
Background technology
Pencil is prevailing schooling apparatus, and the pencil sharpener of cutting pencil is the instrument that we everyone just use from hour marquis, and its uses simple, easy to operate, safe and reliable, is subjected to learner's welcome always.The lateral cross section of a wooden pencil body is generally circle or regular hexagon, the about 8mm of diameter of section, with the process of pencil sharpener cutting pencil is to make wooden by rotation wooden pencil and lead for retractable pencil forms the about 30 ° sharp cone of tapering together, and confession is write, charted, drawing etc.Comprise cutter shell, blade in traditional pencil sharpener structure, blade is fixed on the knife rest in the cutter shell, and blade all has blade from the blade front portion to the blade afterbody, although blade constant slope is installed, when pencil being rotated cutting, wooden body of pencil is being cut with lead for retractable pencil always, and the pencil after the cutting only keeps the lead for retractable pencil of a bit of point, and service time is short, change and cut often, the people causes waste for reaming many lead for retractable pencils, has reduced the lead for retractable pencil utilization rate.Therefore, necessary existing pencil sharpener is improved.
Summary of the invention
The purpose of this utility model provides an a kind of cutting pencil body, keeps the novel pencil sharpener of whole lead for retractable pencils.
The utility model is the improvement to existing pencil sharpener structure, particularly to having the improvement of pencil sharpener blade shapes now.The said novel pencil sharpener structure of the utility model is as follows: a kind of novel pencil sharpener, form by cutter shell, blade, there is fixing hole at the middle part of blade, by screw blade is fixed on the knife rest in the cutter shell, there is blade the blade front portion of blade, the blade rear portion does not have blade, and just the leading portion of blade has blade, and the blade rear does not have blade.
Described novel pencil sharpener, the blade anterior face of blade has one section matsurface, the pencil after the cutting that is used to polish.In addition, this section matsurface can be a concave surface, also can be the face that protrudes.
Because the utility model does not change the outward appearance and the internal structure of former pencil sharpener, only removed the blade at blade rear portion, equally, blade is to tilt to install equally in the cutter shell, when being cut a pencil body circular cone top diameter and equaling lead core diameter, the blade afterbody does not have knife edge part not implement cutting.
The beneficial effect that the utility model is obtained is: it is simple in structure, makes easily the service life of having improved lead for retractable pencil utilization rate and pencil.
