Abstract
The utility model discloses the pencil-knife of the outer bar of a kind of separable cutting Wood pencil and lead for retractable pencil, comprise knife rest, described knife rest is provided with conical slot, the middle part of described slot is provided with some penholder cutting tips near the nose circle of circular cone, further, the middle part of described slot is provided with lead for retractable pencil grinding blade near the cone end of circular cone.The beneficial effects of the utility model: by blade being set to some penholder cutting tips and lead for retractable pencil grinding blade thus making lead for retractable pencil can not cause quick-fried core and disconnected core because cutting output is improper, also solve the problem that tool wear is serious, volume is large, processing technology is complicated and the process-cycle is long simultaneously, and then reach reduction production cost, improve the object of the pencil-knife performance of the outer bar of separable cutting Wood pencil and lead for retractable pencil.
Description
Technical field
The utility model relates to technical field of office stationery, specifically, relates to the pencil-knife of the outer bar of a kind of separable cutting Wood pencil and lead for retractable pencil.
Background technology
The pencil-knife of the outer bar of separable cutting Wood pencil and lead for retractable pencil is instrument conventional in the daily study and work of people.The pencil-knife of the outer bar of separable cutting Wood pencil in the market and lead for retractable pencil is probably divided into two classes: blade cuts the pencil-knife of penholder and the outer bar of lead for retractable pencil class separable cutting Wood pencil and lead for retractable pencil and the pencil-knife of the outer bar of the separable cutting Wood pencil of hobboing cutter class and lead for retractable pencil simultaneously.
The pencil-knife of the outer bar of separable cutting Wood pencil and lead for retractable pencil, when working, is cut pencil by blade.But, because penholder and pen core exist larger difference in material, so they are also different to the requirement of cutting output.Therefore when using blade to cut the pencil-knife of penholder and the outer bar of the separable cutting Wood pencil of lead for retractable pencil class and lead for retractable pencil simultaneously, because its blade is operated on penholder and lead for retractable pencil simultaneously, so very easily cause lead for retractable pencil to burst and the core that breaks, meanwhile, blade excessive wear is also caused.The pencil-knife of the outer bar of the separable cutting Wood pencil of hobboing cutter class and lead for retractable pencil then circulates to cut by multiple-cutting-edge mouth and ensures that the sharpness of cutter is to complete cutting with the wearing and tearing reducing cutting edge.But hobboing cutter class cutter volume is comparatively large, processing technology is complicated and the process-cycle is longer, thus causes production cost higher.
Therefore, develop a lightly easy, blade abrasion is little and the pencil-knife of the outer bar of the separable cutting Wood pencil of non-explosive core and disconnected core and lead for retractable pencil just becomes the problem that insider needs solution badly.
Utility model content
Serious for tool wear in correlation technique, lead for retractable pencil explosion and the core that breaks, the problems such as tool sharpening complex process, the utility model proposes the pencil-knife that the wooden outer bar of a kind of Wood-bar pencil and lead for retractable pencil separate the outer bar of the separable cutting Wood pencil cut and lead for retractable pencil, wooden outer bar and lead for retractable pencil can be separated cutting by the pencil-knife of the outer bar of described separable cutting Wood pencil and lead for retractable pencil in working angles, tool wear degree is reduced, and avoid because the improper quick-fried core that causes of cutting output and disconnected core problem, and, the pencil-knife volume that the outer bar of described separable cutting Wood pencil and the pencil-knife of lead for retractable pencil solve hobboing cutter class separable cutting Wood pencil bar and lead for retractable pencil is outward large, the shortcomings such as processing technology complicated and process-cycle is long.
For realizing above-mentioned technical purpose, the technical solution of the utility model is achieved in that
The pencil-knife of the outer bar of a kind of separable cutting Wood pencil and lead for retractable pencil, comprise knife rest, described knife rest is provided with conical slot, the middle part of described slot is provided with some penholder cutting tips near the nose circle of circular cone, further, the middle part of described slot is provided with lead for retractable pencil grinding blade near the cone end of circular cone.
Wherein, when the number of described some penholder cutting tips is two, described two penholder cutting tips shift to install up and down on described slot.
Wherein, the projection of described two penholder cutting tips in same level is symmetrical.
Wherein, described lead for retractable pencil grinding blade is provided with cutting feeding stoping block.
Wherein, described lead for retractable pencil grinding blade is carborundum disc.
The beneficial effects of the utility model: by blade being set to some penholder cutting tips and lead for retractable pencil grinding blade thus making lead for retractable pencil can not cause quick-fried core and disconnected core because cutting output is improper, also solve the problem that tool wear is serious, volume is large, processing technology is complicated and the process-cycle is long simultaneously and then reach reduction production cost, improving the object of the pencil-knife performance of the outer bar of separable cutting Wood pencil and lead for retractable pencil.

Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, the every other embodiment that those of ordinary skill in the art obtain, all belongs to the scope of the utility model protection.
As shown in Figures 1 to 6 according to embodiment of the present utility model, provide the pencil-knife of the outer bar of a kind of separable cutting Wood pencil and lead for retractable pencil, comprise knife rest 4, described knife rest 4 is provided with conical slot, the middle part of described slot is provided with some penholder cutting tips 2 near the nose circle of circular cone, further, the middle part of described slot is provided with lead for retractable pencil grinding blade 3 near the cone end of circular cone.
In an embodiment, described lead for retractable pencil grinding blade 3 is provided with and cuts feeding stoping block 6, and described lead for retractable pencil grinding blade 3 is carborundum disc.
In an embodiment, when the number of described some penholder cutting tips 2 is two, described two penholder cutting tips about 2 shift to install on described slot, and the projection of described two penholder cutting tips 2 in same level is symmetrical.
During concrete enforcement, the number of described penholder cutting tip 2 can be one, i.e. the pencil-knife of the outer bar of the separable cutting Wood pencil of single blade and lead for retractable pencil, also can more than two, is used for the pencil-knife of the separable cutting Wood pencil of alternative hobboing cutter class bar and lead for retractable pencil outward.
In sum, by means of technique scheme of the present utility model, by blade being set to some penholder cutting tips 2 and lead for retractable pencil grinding blade 3 thus making lead for retractable pencil can not cause quick-fried core and disconnected core because cutting output is improper, also solve the problem that tool wear is serious, volume is large, processing technology is complicated and the process-cycle is long simultaneously and then reach reduction production cost, improving the object of the pencil-knife performance of the outer bar of separable cutting Wood pencil and lead for retractable pencil.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
