Abstract

本发明属办公文具技术领域,具体涉及一种铅笔刀。其特征是:在刀体上设有两个呈锥状的左铅笔孔和右铅笔孔,在右铅笔孔内端设定位块,上方装有短刀片,在左铅笔孔上方装有长刀片,短刀片上设有条形孔通过螺钉固定于刀体上;在刀体侧边的镶嵌插槽内设有一刀片,刀片上设有一端开口的矩形刀刃。因而具有铅笔芯长度可调,笔芯不断,能根据答题需要将笔尖削成不同形状的优点。

Description

铅笔刀
技术领域:本发明属办公文具技术领域,具体涉及一种铅笔刀。
背景技术:现有的铅笔刀大多只有一种削铅笔孔、一个刀片,使用时,削笔杆和削铅笔芯同时完成,铅笔芯长度不能确定,易造成笔芯折断,且无法修整笔尖的形状。
发明内容:本发明的目的是提供一种铅笔芯长度可调,笔芯不断,能根据答题需要将笔尖削成不同形状的铅笔刀。
本发明的技术方案是:一种铅笔刀,由刀体和刀片组成,其特征是:在刀体上设有两个呈锥状的左铅笔孔和右铅笔孔,在右铅笔孔内端设定位块,上方装有短刀片,在左铅笔孔上方装有长刀片,短刀片上设有条形孔通过螺钉固定于刀体上;在刀体侧边的镶嵌插槽内设有一刀片,刀片上设有一端开口的矩形刀刃。
由于采用上述技术方案,当需用矩形笔尖时,先通过条形孔调节短刀片在刀体上的位置,通过定位块来确定削出的铅笔芯长度,再用插槽内的刀片将笔芯修成矩形,没特殊需要,使用长刀片可削成普通的笔尖,因而具有铅笔芯长度可调,笔芯不断,能根据答题需要将笔尖削成不同形状的优点。
附图说明:以下结合附图和具体实施例来对本发明的技术方案做进一步说明。
附图是本发明的结构示意图。
具体实施方式:参考附图,一种铅笔刀,由刀体1和刀片组成,在刀体1上设有两个呈锥状的左铅笔孔6和右铅笔孔5,在右铅笔孔5内端设定位块3,上方装有短刀片2,在左铅笔孔6上方装有长刀片4,短刀片2上设有条形孔8通过螺钉固定于刀体1上;在刀体1侧边的镶嵌插槽内设有一刀片7,刀片7上设有一端开口的矩形刀刃9。
