Abstract

The utility model relates to a stationery article, in particular to a non-breaking lead pencil sharpener. The non-breaking lead pencil sharpener is composed of a cutter frame, a blade, a core-sharpening piece, etc. The blade is used for cutting wooden pencil bodies of the pencil in rotary way, but the blade is not used for cutting the harder and crisper pencil cores in the rotary way. Thus, the blade is not easy to be abraded, and the blade has long service life. The pencil core can not be broken off, and the pencil core can be elongated arbitrarily. The pencil core which is cut in the rotary way is sharpened a plurality of times lightly on the core-sharpening piece, and then the point of the pencil with a circular shape, a nib shape, an inclined shape, etc., can be sharpened. The utility model can be used according to needs.

Description

Non-breaking lead pencil sharpener

The utility model relates to the pencil sharpener of a kind of stationery, particularly a kind of continuous core.

The pencil sharpener that uses mostly is that blade directly changes wooden handwriting and the hard crisp pen core that sharpens a pencil at present.Thereby, change the too sharp and length of the pencil pen core cut out and fix.Moreover the inner end of blade is for a long time with easy to wear, and pen core was easily twisted off when commentaries on classics sharpened a pencil again.

The utility model is intended to overcome the above-mentioned defective of existing pencil sharpener, and the wooden handwriting that a kind of commentaries on classics sharpen a pencil is provided and does not cut the pencil sharpener of pen core.

For achieving the above object, the utility model is that it is made of knife rest, blade, screw, knockout hole and mill chip to the improvement of existing pencil sharpener.This kind pencil sharpener suitably shortens blade, thereby the diameter in knockout hole is suitably increased, the wooden handwriting that causes blade to change to sharpen a pencil and do not change and cut pen core.Like this, not only prolong in blade service life, do not twist off pen core, still can obtain long arbitrarily pen core.(inner or outside) is provided with mill chip on knife rest, the mill chip branch assign formula with bonded type, can be made into metal files sheet type, also available nonmetal fine sand is sticking to be coated with.Change pen core after cutting on mill chip, grind gently several down, can grind the nib of round shape, pointed or inclined to one side shape.

Owing to adopt above-mentioned technical solution, the utlity model has lot of advantages: the one, blade does not change cuts hard crisp pen core, the blade long service life, pen core is not twisted off yet and can be got random length; The 2nd, pen core can grind the nib of required form on mill chip.

Accompanying drawing is a structural representation of the present utility model.

Referring to accompanying drawing, the utility model is made of knife rest 1, screw 2, blade 3, knockout hole 4 and mill chip (5,6).Knife rest 1 can be made into multiple toy shape, and blade 3 usefulness screws 2 are fixed on the knife rest 1.Because the suitable shortening of blade 3, can make the diameter in knockout hole 4 diffuse into blade 3 does not change and cuts pen core.Also be provided with mill chip (5,6) on knife rest 1, mill chip 5 is that metal files sheet type is assigned formula, and mill chip 6 is nonmetal fine sand bonded types.

Claims

1, a kind of pencil sharpener of continuous core, it is made of knife rest (1), screw (2), blade (3), knockout hole (4) and mill chip (5,6), it is characterized in that blade (3) is fixed on the knife rest (1) with screw (2), also be provided with knockout hole (4), mill chip (5,6) on the knife rest (1).

2, the pencil sharpener of continuous core according to claim 1, it is characterized in that knife rest (1) is provided with more than one mill chip (5 or 6), its mill chip (5 or 6) is fine sand type metal files sheet type or nonmetal, can assign or be bonded on the knife rest (1).
