Abstract
The utility model provides a pencil sharpener with double hole cutting function, which is easy to be used and difficult for a lead to be broken. A shell body is provided with a first taper hole for inserting a pencil. A circumference side corresponding to the taper hole is fixedly provided with a blade. A derivation commissure which is extended along an axial direction is arranged between the blade and the first taper hole. The end of a wimble hole is provided with a circular hole for inserting and containing a lead core. The utility model is characterized in that the circumference side of the first taper hole is provided with a second taper hole, the end of the second taper hole is provided with the wimble hole for inserting the lead core, and the taper holes are communicated with the wimble hole. The position of the wimble hole is fixedly provided with another blade whose blade mouth and the wimble hole form the function of cutting the lead core. In this way, the utility model can ensure that the first taper hole and the blade on the first taper hole can only be used for peeling and shaving the wooden layer of the pencil. The lead core can not be damaged. After the pencil is moved in the second taper hole, only the lead core is peeled and shaved.
Description
The utility model relates to a kind of stationery, and a kind of especially have the pencil that diplopore cuts effect and cut device.
The apparatus that cuts of pencil is divided into two classes at present: a class is various cutter, another kind of is to have the pencil of single hole to cut device, the former juvenile uses not really safe, and the latter's result of use is not good enough, its reason just is that pencil is when the insertion bellmouth is cut, the wooden covering of pencil is different with the hardness of inner lead for retractable pencil, therefore, the very easy breakdown of its lead for retractable pencil when cutting the different material of two kinds of hardness simultaneously with a cutter, and the lead for retractable pencil section after cutting is short and taper too, very easy again in use breakdown has not only caused the waste of pencil, and often stubborn cutting just has one for several times, the secondary success.Increased the inconvenience of using to the pupil.Especially when pencil lead departs from, its more easily broken lead.
The purpose of this utility model just is to overcome the above-mentioned shortcoming and defect of prior art, has diplopore and cuts effect and provide a kind of, and neither easily broken lead can guarantee that again the pencil of quick, high-quality exploitation quality cuts device.
The purpose of this utility model is to realize by following technical scheme:
Offer first bellmouth for the pencil insertion on a housing, be fixed with a blade corresponding to all sides of bellmouth, a derivation sealing that extends is vertically arranged between the blade and first bellmouth, the end of taper hole has one to supply lead for retractable pencil to insert the circular hole of appearance, it is characterized in that; Be provided with second bellmouth in all sides of first bellmouth, second bellmouth is not held and is provided with lead for retractable pencil plant taper hole, bellmouth and taper hole connect, be fixed with another blade at the taper hole place, the cutting edge of another blade and taper hole form the effect that lead for retractable pencil is cut, and like this, can guarantee that first taper hole and cutter thereof only shell plane to the pencil layer of wood, and can not undermine lead for retractable pencil, move into behind second taper hole and then only lead for retractable pencil is shelled plane.
Therefore: remarkable result of the present utility model is:
The first,, thereby avoided the unfavorable and lead for retractable pencil breakdown problem of feed that causes because of layer of wood is different with lead for retractable pencil hardness owing to adopted layer of wood and lead for retractable pencil are shelled the double-pore structure of plane respectively separately.
The second, because when layer of wood being shelled plane, the lead for retractable pencil section that it exhumes can move in the lead for retractable pencil containing hole of no blade, therefore, can be on demand and control or lengthening lead for retractable pencil segment length, solved that former existing lead for retractable pencil section is too short when once cutting crosses point and easily breakdown and need frequently cut the problem of system.
Three, because lead for retractable pencil is difficult for breakdown, thereby, can reduce expenses.
Concrete structure of the present utility model is realized by the following examples and accompanying drawing:
Fig. 1 is a section of structure of the present utility model.
Fig. 2 is the A-A profile of Fig. 1.
Fig. 3 is that the A of Fig. 1 is to view.
Below in conjunction with accompanying drawing 1-3 concrete structure of the present utility model is described in detail;
In housing 5, be provided with first bellmouth 1, perisporium sealing place at first bellmouth 1 is fixed with first blade 3, first bellmouth 1 is not held a lead for retractable pencil containing hole 11, it is characterized in that: in the housing of first bellmouth, 1 all sides, be arranged at intervals with second bellmouth 2, second bellmouth 2 is not held a lead for retractable pencil containing hole 21, second blade 4 is fixed on that second bellmouth 2 is not held and the perisporium sealing place of lead for retractable pencil containing hole 21, and first bellmouth 1 does not hold lead for retractable pencil capacity hole 11 segment lengths for the unthreaded hole of blade is not set.See Fig. 1 and Fig. 2.
Architectural feature of the present utility model also is: housing 5 is a hollow housing, the open-position-side spiral-lock of housing 5 has the buckle closure 53 that has two convex blocks 52, first bellmouth 1 and second bellmouth 2 are opened on each convex projection 52, the sealing 521 of slagging tap of first bellmouth 1 and second taper hole 2 communicates with hollow housing 5 inner chambers 51, second bellmouth 2 and not the end lead for retractable pencil containing hole 21 axially offer length greater than first bellmouth 1, be not provided with in the axial segment length's of second bellmouth 2 preceding 2/3 segment length that second blade, 4, the second blades 4 are distributed in that second bellmouth 2 is not held and lead for retractable pencil containing hole 21 total lengths that extend in.Referring to Fig. 1 to Fig. 3.
Using method brief introduction of the present utility model is as follows:
At first the pencil that will not cut or the pencil that need cut again insert in first taper hole 1 of housing 5 and change stubborn, because the cutting edge of the first fixing blade 3 is distributed in the taper hole 11 total length sections in this taper hole, therefore, it is mainly exploited layer of wood, and the lead for retractable pencil section that exhumes is then planted in the lead for retractable pencil containing hole 11 and do not cut.
Then, the pencil that to shell layer of wood is more inserted and to be carried out secondary in people's second taper hole 2 and cut, because the taper hole section of second taper hole 2 is not provided with blade, so layer of wood can not cut substantially, insert the cutting of second blade 4 that lead for retractable pencils in the lead for retractable pencil containing hole 21 of second taper hole, 2 latter ends then are subjected to being positioned at this hole segment length.This post forming can be carried out independent respectively cutting to layer of wood and inner lead for retractable pencil respectively, so can prevent the generation of disconnected plumbous problem well.
