Abstract

本实用新型涉及一种刨削铅笔用的螺旋刀片削笔器，包括刀座及连接其上的刀片，刀座中设有锥形削笔孔，刀片的刃边位于锥形削笔孔的排屑缝处，刀片立体形状为螺旋上升曲面，刀座和刀片的连接安装面也为相应形状。本实用新型的刀片刃边构成上升的螺旋线，削笔时可以使笔尖的受力点沿螺旋线均匀滑动，刀片的切削方向和笔尖的木质纤维形成角度，刨削面比较光滑、整齐，刨削平稳，效果好，笔芯不易断。而且，本实用新型的结构简单紧凑，成本低，便于携带。

Description

螺旋刀片削笔器
技术领域：本实用新型涉及一种刨削铅笔用的削笔器。
背景技术：一般的直刃刀片式削笔器结构非常简单紧凑，便于携带，成本低，但刨削效果不够理想，削笔时笔尖受力不均容易折断笔芯。现在有滚刀式的削笔器，利用两个滚刀均匀快速削笔，效果较好，笔芯不易断，但结构复杂，成本高，体积也较大，携带不够方便。
发明内容：针对现有技术的不足，本实用新型提供一种结构简单紧凑，削笔效果好的螺旋刀片削笔器。
本实用新型包括刀座及连接其上的刀片，刀座中设有锥形削笔孔，刀片的刃边位于锥形削笔孔的排屑缝处，刀片立体形状为螺旋上升曲面，刀座和刀片的连接安装面也为相应形状。
本实用新型的刀片刃边构成上升的螺旋线，削笔时可以使笔尖的受力点沿螺旋线均匀滑动，刀片的切削方向和笔尖的木质纤维形成角度，刨削面比较光滑、整齐，刨削平稳，效果好，笔芯不易断。而且，本实用新型的结构简单紧凑，成本低，便于携带。
下面结合附图和实施例进一步说明本实用新型。
附图说明：图1是实施例的主结构示意图；
          图2是图1的左视图。
实施例：如图所示，刀片2连接在刀座1上，刀座1中设有锥形削笔孔3，刀片2的刃边位于锥形削笔孔3的排屑缝5处，刀片1立体形状为螺旋上升曲面，刀座1和刀片2的连接安装面也为相应形状。使用时，只需将铅笔头插入锥形削笔孔3中转动，在刀片2的刃边刨削下，即可均匀快速的削出笔尖，削下的笔屑从排屑缝5中排出。按照一般人的操作习惯，本实施例的刀片2上升方向为右旋，当然也可以根据要求改为左旋。本实施例在刀座1外部还套有活动罩4，这样可以美观装饰，并且还可以暂时容纳排出的笔屑，保持使用环境卫生。
