Abstract
The utility model discloses a versatile pencil sharper which comprises a blade rack, a blade, a fix screw and a guiding positioning ring which is actively matched with the internal hole of the head of the blade rack and is internally provided with pencil positioning hole. One end of the internal hole of the blade rack head is provided with a positioning slot, another end of the guiding positioning ring is provided with teeth positioning block which is positioned in the positioning slot. The section shape of the pencil positioning hole of the guiding positioning ring is confirmed according to the overlapping shape of 1-6 pencils. The utility model has the advantages of reasonable structure, simple and reliable blade fixing way, convenient positioning ring dismounting, and can sharpen pencils into different shapes.
Description
Technical field
The utility model relates to a kind of pencil sharpener, especially with to roll up the pencil sharpener of cutting the arbitrary shape pencil relevant.
Background technology
Existing pencil sharpener can only be rolled up usually and cut cylindrical or the regular polygon pencil, cut flat or other non-regular polygon abnormity pencil and can't roll up, as carpenter's pencil etc., limited the range of application of pencil sharpener greatly, in addition, existing pencil sharpener also exists blade fixed form complexity, deficiencies such as centring ring mounting or dismounting inconvenience.
Summary of the invention
The purpose of this utility model provides a kind of rational in infrastructure, and the blade fixed form is simple and reliable, and the centring ring mounting or dismounting are convenient, can roll up the omnipotent pencil sharpener of cutting the difformity pencil.
For achieving the above object, the utility model is achieved through the following technical solutions.Omnipotent pencil sharpener, comprise knife rest, blade, fixed screw and guide-localization circle, the guide-localization circle cooperates with the endoporus of knife rest head is movable, is provided with the pencil locating hole in the guide-localization circle, endoporus one end at the knife rest head is provided with locating slot, guide-localization circle one end is provided with the profile of tooth locating piece, and the profile of tooth locating piece snaps in the locating slot, and the cross sectional shape of the pencil locating hole in the guide-localization circle is determined according to the 1-6 kind shape of pencils to be sharpened is overlapping.
Described omnipotent pencil sharpener, its knife rest head are the composite construction of frame and annulus, and locating slot is between frame and annulus axial end, and locating slot is a penetrating groove up and down.
Described omnipotent pencil sharpener, its blade are the arc-shaped elastic blade, and the circular arc of blade is greater than the circular arc of knife rest cutter installation place, and the hole that fixed screw passes the blade middle part is screwed in the screw on the knife rest and is pressing blade.
The utility model compared with prior art has the following advantages: (one) is that compact conformation is reasonable, only being inserted in the guide-localization circle at the knife rest head realizes rolling up the purpose of cutting the arbitrary shape pencil, and size is the same with common pencil sharpener, profile is more elegant in appearance, and the mounting or dismounting of guide-localization circle are convenient, are convenient to install and change; (2) be by changing the shape of pencil locating hole on the guide-localization circle, the volume that can adapt to the respective shapes pencil is cut, and the shape of pencil locating hole can overlappingly establish several, overlapping as regular polygon and pancake, just can roll up and cut common pencil and carpenter's pencil, solve the chinagraph pencil volume and cut difficult problem; (3) be that blade is the arc-shaped elastic blade, cancelled the location lug on the knife rest, because the circular arc of blade is greater than the circular arc of knife rest cutter installation place, the hole that fixed screw passes blade middle part is screwed in the screw on the knife rest and is pressing blade, not only simplify the structure, and it is more reliable that blade is connected with knife rest, improved the stability that volume is cut.
