Description

本实用新型涉及一种削铅笔用的双眼及多孔削笔刀。
现有的削笔刀样式繁多,但因只有一只削笔孔及刀片,很易削断笔芯。
本实用新型的目的旨在提供一种不易削断笔芯的削笔刀。
一种双眼及多孔削笔刀,由刀片和刀架体组成,其结构特点是刀架体上设有大小不一的数只削笔孔及相应的刀片。使用时,将铅笔先放入小孔中车削出一小截铅芯后,再放入大孔中继续车削,因刀片与中心线的夹角增大,就只能车削到铅芯和靠近铅芯的那一小段薄薄的木材。
本产品相比老产品可明显减少削断笔芯的现象,提高铅笔利用率,且结构简单。
附图1为双眼削笔刀的一实施例结构示意图。
图2为图1结构使用状态示意图。
图3为五孔削笔刀的一实施例结构示意图。
参见附图,双眼削笔刀设有一大一小两个削笔孔及刀片,五孔削笔刀设有两大三小五个削笔孔及刀片。其削笔孔一般为2~9只,孔径大小至少有两种,也可两种以上。削笔孔可布置在刀架体的同一侧面,也可布置在多个侧面。
