Abstract
Can change a pencil-knife for pencil-lead appearance and size, this pencil-knife has " V " shape sheet blade, the cutting tip of this blade, is divided into wooden cutting tip and upwarp blade, wooden cutting tip with upwarp blade with 0 ° ~ 16 ° angles; On the tool rest upwarping blade bottom, be provided with the gradient that the upper uplifting angle that cuts lead for retractable pencil with new cutter matches, this gradient be 0 ° ~ 16 ° with the new blade that this upwarps blade upwarp angle be 0 ° ~ 16 ° identical; For roller blade lead pencil knife, its wooden cutting roller cutter cutting wooden part is cylindrical roller cutter, the new roller cutter of cutting lead for retractable pencil cutting lead for retractable pencil part is truncated cone roller cutter, and with an angle between wooden cutting roller cutter and the new roller cutter of cutting lead for retractable pencil, its new roller cutter tapering is 0 ° ~ 16 °.This pencil-knife structure is simple, easy to use, and the pencil-lead moderate dimensions cut out is practical, not easily broken lead, applied range, is well suited for student and uses.
Description
Technical field
The utility model relates to a kind of lead pencil knife, especially a kind of pencil-knife that can change pencil-lead appearance and size.
Background technology
At present, the pencil-knife on market divides two classes, blade type and roller blade, but it is the same that this two classes pencil sharpener cuts out the lead for retractable pencil profile come, mainly cut out the wooden part of pencil come very long, and lead for retractable pencil part is very short and very sharp, when writing, the lead for retractable pencil of point point easily fractures.The wooden part that this two classes pencil sharpener cuts out is very disproportionate with lead for retractable pencil part, both unsightly also impracticable.If want to allow the pencil-lead length cut out, so the wooden part of pencil will become longer, and the blade cut like this will be very long, be inconvenient to use.So provide one can cut out its front end not very sharp pencil-lead just seem very necessary.
Utility model content
In order to overcome, the pencil lead part that existing lead pencil knife cuts out is short, point and the problem that easily fractures, the utility model provides a kind of pencil-knife that can change pencil-lead appearance and size, this kind can change the pencil-knife of pencil-lead appearance and size by original blade is done simple improvement, make the pencil-lead moderate dimensions cut out, not easily broken lead, meets the instructions for use of people; This pencil-knife structure is simple, small volume and less weight, simple and practical, applied range.
The utility model solves the technical scheme that its technical problem adopts: a kind of pencil-knife that can change pencil-lead appearance and size, comprising: the wooden part of pencil, wooden cutting tip, new cutter cut lead for retractable pencil, upwarp blade, new blade upwarps angle, former cutter cuts lead for retractable pencil; This pencil-knife has " V " shape sheet blade, the cutting tip of this blade, be divided into wooden cutting tip and upwarp blade, wooden cutting tip with upwarp blade with 0 ° ~ 16 ° angles, the wooden part of such cutting pencil out can not only change shape, can also allow the new cutter cut out cut lead for retractable pencil cut lead for retractable pencil with former cutter compared with more slender, its front end is no longer pointy appearance, also not easily broken core.This pencil-knife is compared with existing pencil-knife structure, on the tool rest upwarping blade bottom, be provided with the gradient that the upper uplifting angle that cuts lead for retractable pencil with new cutter matches, this gradient be 0 ° ~ 16 ° with the new blade that this upwarps blade upwarp angle be 0 ° ~ 16 ° identical, the change of this angle can depending on the condition of lead for retractable pencil use, long or short or heavy manual labour or thin.
For roller blade lead pencil knife, comprising: wooden cutting roller cutter, cutting lead for retractable pencil new roller cutter, new roller cutter cut lead for retractable pencil, former roller cutter cutting lead for retractable pencil, new roller cutter tapering; Its wooden cutting roller cutter cutting wooden part is cylindrical roller cutter, the new roller cutter of cutting lead for retractable pencil cutting lead for retractable pencil part is truncated cone roller cutter, with an angle between wooden cutting roller cutter and the new roller cutter of cutting lead for retractable pencil, its new roller cutter tapering is 0 ° ~ 16 °, compared with cutting lead for retractable pencil with former roller cutter, cut lead for retractable pencil new roller cutter and cut out the slender lead for retractable pencil that the new roller cutter cutting lead for retractable pencil come is applicable use, its end also can not form the sharp cone distal of special point.
The beneficial effects of the utility model are: this pencil-knife structure is simple, easy to use, and the pencil-lead moderate dimensions cut out is practical, not easily broken lead, applied range, are well suited for student and use.
