Description

A kind of porous lead pencil knife

Technical field

The utility model is related to a kind of pencil-knife, more particularly to a kind of porous lead pencil knife.

Background technology

Pencil is daily life and the requisite stationery of study, and it is not only safe and reliable, writes correction conveniently, also It is simple with production, the characteristics of environment friendly and pollution-free；But when in use, need using cutter pencil tip to be carried out cutting exposing Carbon core, this is the biggest obstacle for affecting the actually used property of pencil, and at present conventional Pencil sharpener includes rotary pencil-sharpener And sheet cutter, but the stock-removing efficiency of pencil can not be effectively improved.

In order to improve the efficiency and applicability of cutting, people have carried out various innovations to pencil cutting instrument, and such as China is special A kind of porous pencil-knife disclosed in sharp ZL201220498911, it is provided with multiple for pencil insertion on same pencil-knife The pore structure of chip, by pore structure different diameters are designed to, to meet the cutting needs of the pencil to different thicknesses specification；So And it is actually used in, the specification of pencil is mostly to unify the hexagon specification of prospects, therefore the practical significance of the design and less.

Currently, the pencil of same specification is often cut into the shape of different purposes by user, is such as write, describes, is made Picture line etc. has different requirements to the taper of pencil cutting rear tip, thickness and length etc., and same pencil-knife is often difficult to Satisfaction uses needs.

Utility model content

The purpose of this utility model is to provide a kind of porous lead pencil knife, and it has a compact conformation, cut it is easy to use and The characteristics of feature richness.

The utility model is achieved like this, a kind of porous lead pencil knife, it includes housing, it is characterised in that the shell Body is loose structure, and a toolbox is arranged in each corresponding housing in pore structure position, and each toolbox includes one The individual taper being fixedly connected on housing and the blade being embedded on knife rest；The cone of the corresponding knife rest of described each toolbox Degree is different.The tip inlets diameter of the knife rest that each toolbox is included is different in some toolboxs.

Preferably：The housing of the lead pencil knife is to arrange in double-pore structure, each corresponding housing in pore structure position One toolbox, the taper of the knife rest that two toolboxs are included and the tip inlets diameter of knife rest it is different.

The lead pencil knife also includes the electric assembly for driving pencil to rotate and for gripping determining for positioning pencil Hyte part.The electric assembly includes motor and is connected to the driving gear of motor output end.The positioning component bag The driven gear engaged with driving gear is included, the driven gear is provided centrally with being enclosed within pencil and plays positioning with fixation Hexagonal hole structure.

The beneficial effects of the utility model are：The utility model is by the knife rest of different tapers and open pointed tip different-diameter Pencil sharpener component focus in a housing so that lead pencil knife can chip obtain sophisticated difference taper Pencil, moreover it is possible to which cutting obtains the pencil that tip length is not waited with thickness, and with reference to electronic cutting control, it is not only different by cutting Knife rest obtaining the suitable nib wanted, effectively meet the actual demand of user, improve applicability, but also effectively Improve stock-removing efficiency and the convenience for using.

Specific embodiment

Specific embodiment of the present utility model is described further below in conjunction with the accompanying drawings.

As shown in Figure 1-2, the utility model is achieved in that a kind of porous lead pencil knife, and it includes housing 1, its knot Structure feature is that the housing 1 is that a toolbox is arranged in loose structure, each corresponding housing 1 in the position of pore structure 2, each Toolbox includes a taper 4 being fixedly connected on housing 1 and the blade 3 being embedded on knife rest 4；Described each knife The taper of the corresponding knife rest 4 of tool component is different；In being embodied as, the taper of the corresponding knife rest 4 of each toolbox from It is little to big or arrange gradually from big to small；The utility model when in use, can need for pencil to insert corresponding hole according to cutting In structure 2, coordinated with blade 3 using knife rest 4, blade 3 completes the cutting to pencil in pencil rotation, due to the cone of knife rest 4 Degree different designs so that pencil tip finally cuts into different tapers, to meet the different purposes needs of pencil；Due to porous Design, can simultaneously complete the cutting task that pencil tip difference taper needs, and greatly improve applicability and stock-removing efficiency.

In order to the use needs, the tip inlets 5 of the utility model also cutter setting frame 4 that further improve pencil tip are carried out Improve, i.e., the diameter of tip inlets 5 of the knife rest 4 that each toolbox is included is different in described some toolboxs；In tool During body is implemented, the diameter of tip inlets 5 of the corresponding knife rest 4 of each toolbox is arranged from small to large or from big to small gradually, such as Fig. 3 and embodiment illustrated in fig. 4, the tip inlets 5 of the knife rest 4 of embodiment illustrated in fig. 3 are relatively large in diameter, it is suitable cutting obtain tip compared with Thick and long pencil, is mainly used in bar and scribbles；And the diameter of tip inlets 5 of the knife rest 4 of embodiment illustrated in fig. 4 is less, it is adapted to Cutting obtains the thinner pencil in tip, is mainly used in setting-out and writes.The design causes the sophisticated thickness of the pencil after the completion of cutting It is different with length, meet drawing and scribble wait difference needs.

So the utility model designs various different tapers, different point degree and corresponding different length inside a product The knife rest of degree realizing various demands of consumer, such as when painting, it is sometimes desirable to which it is very long scribbling to expose nib portion, needs sometimes Want nib very sharp to describe, it is sometimes desirable to which tip is longer writing, obtain what is wanted by cutting different knife rests Suitable nib, effectively meets the actual demand of user.

The utility model is preferably designed：The housing 1 of the lead pencil knife be double-pore structure, each position of pore structure 2 One toolbox is set in corresponding housing, and the taper of the knife rest 4 that two toolboxs are included and the tip inlets 5 of knife rest 4 are straight Footpath is different；It can simultaneously meet the cutting of two kinds of pencils, and compact conformation is convenient and practical, and the scope of application is more extensive.

The utility model have also been devised electronic cutting structure, such as Fig. 5 for the convenience for improving stock-removing efficiency and use With shown in Fig. 6, the lead pencil knife have also been devised the electric assembly for driving pencil to rotate and for gripping positioning pencil Positioning component；The electric assembly and positioning component are arranged on the lower section of pore structure 2 in housing 1, and the electric assembly includes electronic Machine 8 and the driving gear 7 of the output end of motor 8 is connected to, the positioning component includes the driven gear engaged with driving gear 7 6, the driven gear 6 is provided centrally with being enclosed within pencil the hexagonal hole structure for playing positioning and fixation；When in use, lead Penholder enters in pore structure 2 and hexagonal hole structure, completes positioning and fixes, the blade 3 on the lower end of pencil and knife rest 4 and knife rest 4 Tight contact between, motor 8 starts drive driving gear 7, the engagement in rotation of driving gear 7 drives driven gear 6 to rotate, driven gear 6 drive the pencil rotation being inserted in hexagonal hole structure, and then blade 3 completes cutting to the end of pencil.
