Abstract

The utility model discloses a novel pencil sharpener, which comprises a shell. One side of the shell is provided with a chipping storage cavity, and the other side of the shell is provided with a cutter frame; the cutter frame is respectively provided with a conical shell rolling cutting holder and a conical core rolling cutter holder, the opening of the shell rolling cutting holder is matched with a pencil body, and the opening of the core rolling cutter holder is matched with a pencil core; the shell rolling cutting holder is provided with a large shell rolling cutter; the core rolling cutter holder is provided with a small core rolling cutter; the tail end of the shell rolling cutter holder is communicated with the chipping storage cavity; and the tail end of the core rolling cutter holder is provided with a baffle in the vertical direction. Since the shell and the core of a pencil are cut or sharpened separately, the force and depth can be easily controlled, the core of the pencil cannot be broken easily, and the purpose of saving materials can be achieved. Since the baffle is additionally arranged at the tail end of the core rolling cutter holder and vertical to the axial line, a small core rolling blade can automatically stop cutting when the pencil core is sharpened to a certain length, the service life of the pencil can be greatly prolonged, and the service life of the pencil sharpener can be correspondingly prolonged.

Description

A kind of novel pencil sharpener

Technical field

The utility model relates to a kind of pencil sharpener, relates in particular to a kind of pencil sharpener of novel roll cutting pencil, belongs to the daily living article field.

Background technology

There is weak point in pencil sharpener in the market: one, the nib of cutting out be point too, easily scratches paper when writing, and nib fractures easily, because nib thickness difference is too big, causes writing inhomogeneous when writing; Its two, blade or milling cutter are too big to the cutting output of pencil-lead, because the hardness of timber and pen core is different, cause the pen core fracture easily during cutting, lead for retractable pencil most of actual that reamed rather than write wasted very big; Its three, have only an edge of a knife, and pencil is by shell with pen core is two-layer constitutes, the hardness and the toughness of shell and pen core are different, pen core is hard and crisp, shell is soft and tough, both holding capacity are different, it is firmly heavy slightly during volume that then pen core is easily broken.

The utility model content

At the deficiency that prior art exists, technical problem to be solved in the utility model is, a kind of novel pencil sharpener is provided, the meticulous and problem too big of nib that has solved the easy disconnected pencil-lead of volume and cut out to the cutting output of pencil, and easy to use, production cost is low.

For solving the problems of the technologies described above, the technical scheme that the utility model is taked is, a kind of novel pencil sharpener comprises shell, and shell one side is storage bits cavitys, and its shell opposite side is provided with knife rest; Be respectively equipped with volume shell tool rest and volume core tool rest on the knife rest, volume shell tool rest and volume core tool rest are taper, and the opening and the handwriting of volume shell tool rest are suitable, and the opening and the pen core of volume core tool rest are suitable; Volume shell tool rest is provided with big volume shell cutter; Volume core tool rest is provided with rouleau core cutter; The tail end of volume shell tool rest communicates with storage bits cavity; The tail end vertical direction of volume core tool rest is located at a plate washer.

Optimize, above-mentioned novel pencil sharpener, the length of its big volume shell cutter is 2cm; The length of rouleau core cutter is 0.5cm.

Optimize, above-mentioned novel pencil sharpener, its shell adopt rigid plastics to make.

Optimize, above-mentioned novel pencil sharpener, it is rolled up shell tool rest and rolls up greatly between the shell cutter and connects by screw; Connect by screw between described volume core tool rest and the rouleau core cutter.

The utility model since the shell of pencil and the cutting of lead for retractable pencil carry out respectively, firmly and depth be easy to grasp, so lead for retractable pencil frangibility has not played the effect of economical with materials; And installed a baffle plate additional in the tail end vertical axis direction of volume core tool rest, thereby can make lead for retractable pencil be cut certain-length the time, rouleau heart blade stops cutting automatically, has prolonged the service life of pencil widely, the also corresponding service life that prolongs pencil sharpener; Owing to adopted the double-pole structure, the pen core after volume is cut can be long arbitrarily, has certain intensity again, and the quality after volume is cut is improved, and is not only applicable to children, and is more suitable to student especially Graphing of Engineering personnel.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is further described;

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is user mode figure of the present utility model.

The specific embodiment

As depicted in figs. 1 and 2, the utility model is a kind of novel pencil sharpener, comprises shell 1, and shell 1 one sides are storage bits cavity 8, and its shell 1 opposite side is provided with knife rest 9; Be respectively equipped with volume shell tool rest 4 and volume core tool rest 6 on the knife rest 9, volume shell tool rest 4 and volume core tool rest 6 are taper, and the opening and the handwriting of volume shell tool rest 4 are suitable, and the opening and the pen core of volume core tool rest 6 are suitable; Volume shell tool rest 4 is provided with big volume shell cutter 2; Volume core tool rest 6 is provided with rouleau core cutter 5; The tail end of volume shell tool rest 2 communicates with storage bits cavity 8; The tail end vertical direction of volume core tool rest 6 is located at a plate washer 7.The length of its big volume shell cutter 2 is 2cm; The length of rouleau core cutter 5 is 0.5cm.Its shell 1 adopts rigid plastics to make.It is rolled up shell tool rest 4 and rolls up greatly between the shell cutter 2 and connects by screw 3; Connect by screw 3 between described volume core tool rest 6 and the rouleau core cutter 5.The cutting shell when lead for retractable pencil stretches out long enough, is changed in following that volume heart tool rest 6 again and is cut lead for retractable pencil earlier.

Certainly, above-mentioned explanation is not to be to restriction of the present utility model, and the utility model also is not limited to above-mentioned giving an example; those skilled in the art; in essential scope of the present utility model, the variation of making, remodeling, interpolation or replacement all should belong to protection domain of the present utility model.
