Abstract
The utility model relates to a pencil sharpener capable of realizing clockwise and anticlockwise rotation sharpening, which is provided with a rectangular case, wherein the front part of the case is provided with an insertion hole capable of being inserted with a pencil, and four cutter blades are fixed on the periphery of the insertion hole in the tangent direction. When the pencil is clockwise rotated, the first cutter blade and the third cutter blade sharpen the pencil in the direction opposite to the pencil rotation tangent direction, and the second cutter blade and the fourth cutter blade are in the direction the same as the pencil rotation tangent direction and can not sharpen the pencil; and when the pencil is anticlockwise rotated, the second cutter blade and the fourth cutter blade sharpen the pencil in the direction opposite to the pencil rotation tangent direction, and the first cutter blade and the third cutter blade are in the direction the same as the pencil rotation tangent direction and can not sharpen the pencil, so the goal of clockwise and anticlockwise sharpening the pencil is reached, meanwhile, the surface of the pencil is smooth, and the pencil sharpener is convenient and practical.
Description
Technical field
The utility model relates to a kind of pencil-knife that sharpens a pencil, and especially can suitablely reverse the pencil-knife of cutting to what different directions rotated.
Background technology
At present, known pencil-knife has only a pencil jack in use, and can only be to a direction rotation, and the pencil surface that cuts out is often smooth inadequately, makes troubles for people's use.
The utility model content
Can only be when cutting pencil to the deficiency of a direction rotation in order to overcome existing pencil-knife, the utility model provides a kind of can suitablely reverse the pencil-knife of cutting, can be to along contrary both direction rotation during this pencil-knife cutting pencil, make the pencil smooth surface after the cutting handy.
The technical scheme that its technical problem that solves the utility model adopts is: this pencil-knife has a rectangular-shaped shell, and the shell front portion is provided with a jack that can insert pencil, and tangential direction is fixed with four blades around jack.When clockwise rotating pencil, a blade and No. three blades cut pencil against the tangential direction that pencil rotates, and No. two blades and No. four blades can not cut pencil along the tangential direction that pencil rotates; When rotating counterclockwise pencil, No. two blades and No. four blades cut pencil against the tangential direction that pencil rotates, blade and No. three blades tangential direction along the pencil rotation, can not cut pencil, can be thereby reach along the purpose of up-cutting pencil.
The beneficial effects of the utility model are, can make the pencil smooth surface to along contrary both direction rotation when people cut pencil, and are convenient and practical.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is a cross section structure principle schematic of the present utility model.
Among the figure, 1. shell, 2. blade, 3. No. two blades, 4. No. three blades, 5. jack, 6 No. four blades.
The specific embodiment
In Fig. 1, this pencil-knife has a rectangular-shaped shell 1, and shell 1 front portion is provided with a jack 5 that can insert pencil, and tangential direction is fixed with four blades around jack 5.When clockwise rotating pencil, a blade 2 and No. three blades 4 cut pencil against the tangential direction that pencil rotates, and No. two blades 3 and No. four blades 6 can not cut pencil along the tangential direction that pencil rotates; When rotating counterclockwise pencil, No. two blades 3 and No. four blades 6 cut pencil against the tangential direction that pencil rotates, blade 2 and No. three blades 4 tangential direction along the pencil rotation, can not cut pencil, can be thereby reach along the purpose of up-cutting pencil.
