Abstract
The utility model discloses a novel pencil sharpener. The novel pencil sharpener comprises a sharpener seat which is provided with a sharpening hole; the diameter of the sharpening hole is slightly greater than that of a pencil; blades are arranged on the side wall of the sharpening hole; the inner ends of the blades are parallel to the central line of the sharpening hole; the outer ends of the blades are inclined outward; the blades are matched with a wedge-shaped block; a sliding block capable of sliding is arranged on the sharpener seat; scale corresponding to the sliding block is arranged on the sharpener seat; the novel pencil sharpener overcomes the defect that the conventional pencil sharpener only sharpens a pencil core into a tapered pencil core, and can sharpen the pencil core into a cylindrical pencil core; the diameter can be adjusted, and the length of a pencil point can be displayed visually; and the novel pencil sharpener is particularly suitable for drawing pencils.
Description
Technical field
The utility model relates to a kind of stationery, specifically a kind of novel pencil sharpener that is applicable to Graphing of Engineering with pencil.
Background technology
At present, known pencil sharpener is to be combined by blade, screw, tool rest.Pencil is inserted in the hole of tool rest, and rotation pencil just can use the pencil sharpening; On this principle, also derive hand and electronic pencil sharpener; But the pencil-lead end of its cutting is all tapered; And for Graphing of Engineering, drawing pencil is had special requirement, cylindrical rather than taper like pencil-lead; Its diameter should be consistent with institute line drawing bar thickness, and existing pencil sharpener can not satisfy above requirement.
The utility model content
The purpose of the utility model provides a kind of simple in structure, can be whittled into pencil-lead cylindrical, the adjustable novel pencil sharpener of diameter simultaneously.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is:
A kind of novel pencil sharpener comprises tool rest, and said tool rest is provided with cutting hole, and said cutting hole somewhat larger in diameter is provided with blade in pencil diameter on the cutting hole sidewall, and blade position can be regulated, and said blade is inner parallel with the cutting hole center line, and the outer end is outward-dipping.
Said blade cooperates with wedge, and the slide block that can slide is set on tool rest, and on tool rest, corresponding with it scale is set.
On tool rest, be provided with nib length and check device, said nib length checks that device comprises that a cylinder cuts, and inner concordant with the pencil-lead end under the effect of spring, the outer end is concordant with tool rest shell face, and is provided with graduation mark in the outer end.
As preferably, said blade is two, and is symmetrically distributed in the cutting hole sidewall.
The beneficial effect of the utility model is:
The utility model has remedied the deficiency that existing pencil sharpener can only be whittled into pencil-lead taper, can pencil-lead be whittled into cylindrically, and simultaneously diameter can be regulated, and nib length can manifest intuitively.Be particularly suitable on drawing pencil, using.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further detailed explanation.
Fig. 1 is the structural representation of the utility model;
The specific embodiment
A kind of novel pencil sharpener comprises tool rest 1, and said tool rest 1 is provided with cutting hole, and said cutting hole somewhat larger in diameter is provided with blade 7 in pencil 4 diameters on the cutting hole sidewall, and said blade 7 the inners are parallel with the cutting hole center line, and the outer end is outward-dipping.
Said blade 7 cooperates with wedge 5, and the slide block 2 that can slide is set on tool rest 1, and on tool rest 1, corresponding with it scale 3 is set.Pencil-lead is very thin, be easy to cut not in place, so scale 3 is chosen higher accuracy value.As preferably, can on slide block 2, positioner be set, anti-limited slip block 2 in use moves.
On tool rest 1, be provided with nib length and check device, said nib length checks that device comprises that a cylinder cuts 9, and inner concordant with pencil-lead 8 ends under the effect of spring 10, the outer end is concordant with tool rest 1 shell face, and is provided with graduation mark 6 in the outer end.
As preferably, said blade 7 is two, and is symmetrically distributed in the cutting hole sidewall.
Its principle and method for using are following:
Adjusting slider 2 is to corresponding scale 3 places; Slide block 2 drives wedge 5, thereby the spacing of adjustment blade 7 guarantees that the spacing of 7 of two parallel blades is consistent with desired pencil-lead 8 diameters; Pencil 4 is inserted cutting hole; Rotation pencil begins cutting, and pencil-lead 8 is cut into cylindrical, and diameter is setting value just; Pencil-lead 8 ends are cut 9 with cylinder and are ejected, and its length that ejects is nib length just, cuts the end at cylinder simultaneously and is provided with graduation mark 6, can manifest the nib length of having cut intuitively.Because error causes pencil-lead to be prone to cut disconnected, when using this pencil sharpener, the diameter of the pencil-lead of setting should be bigger a little than actual needs diameter, measure after cutting out, slowly regulates again in order to prevent.
More than the disclosed specific embodiment that is merely this patent, but this patent is not limited thereto, for the person of ordinary skill of the art, under the prerequisite that does not break away from the utility model principle, the distortion of making should be regarded as belonging to the utility model protection domain.
