Description

一种卷笔刀
【技术领域】
本实用新型涉及一种卷笔刀的改进发明。
【背景技术】
大家在使用铅笔时,一般都会用到卷笔刀,但是目前市场上的卷笔刀存在的不足是,在卷铅笔时,铅笔芯经常会折断并卡在卷笔刀的刀座内,要取出往往很不方便。
【发明内容】
鉴于目前公知技术存在的问题,本实用新型要解决的技术问题是在于提供一种可方便取出折断并卡在刀座内的铅笔芯的卷笔刀。
为解决上述技术问题,本实用新型是采取如下技术方案来完成的:
一种卷笔刀,包括塑料外壳,塑料外壳内设有刀座和刀片,刀座具有与铅笔锥形笔头端适配的圆锥腔,刀片固定在刀座上,其特征在于:所述塑料外壳上设有一通孔,该通孔正对所述刀座的圆锥腔的锥顶,该通孔内可活动穿过顶杆。
上述结构的卷笔刀,如果铅笔芯折断并卡在刀座内,这时只要拿顶杆从正对刀座圆锥腔锥顶的通孔内往圆锥腔方向顶过去,就可轻易地将折断的铅笔芯取出,非常方便。
【附图说明】
图1为本实用新型的结构示意图
【具体实施方式】
如图1所示,本实用新型的卷笔刀,包括塑料外壳1,塑料外壳1内设有刀座3和刀片2,刀座3具有与铅笔锥形笔头端适配的圆锥腔4,刀片2通过螺钉固定在刀座3上,所述塑料外壳1上设有一通孔,该通孔正对所述刀座的圆锥腔4的锥顶,通孔的直径与圆锥腔4的锥顶直径相当,该通孔内可活动穿过顶杆5,顶杆5为细的磁铁棒,顶杆5平时可磁性吸附在所述刀片2上,使用时取下即可。
在卷铅笔时,如果出现铅笔芯折断并卡在刀座内,这时只要拿顶杆从正对刀座圆锥腔锥顶的通孔内往圆锥腔方向顶过去,就可轻易地将折断的铅笔芯取出,非常方便。
