Description

旋转铅笔刀
技术领域:本实用新型属学生用的文具技术领域,具体涉及一种旋转铅笔刀。
背景技术:现有的旋转铅笔刀大致分两种,一种是简易手动的,它是由壳体、刀片组成,使用时,铅笔旋转前行,被刀片切削下来的碎沫,很易掉落在桌上或地上,造成一定的污染,而且也易弄藏双手,不卫生;另一种是半手动的,结构比较复杂,刀片是螺旋柱状,有铅笔固定夹紧装置,下方有垃圾盒,但其价格高,在中小学生中不能普及使用。
发明内容:本实用新型的目的是提供一种结构简单,能防滑的,卫生的旋转铅笔刀。
本实用新型的技术方案是:一种旋转铅笔刀,在盒体上端固有刀片,一侧边设有铅笔口,其特征是:在盒体上端设有向外凸起的上盖,上盖一端与盒体铰接,另一端设有卡扣与盒体上设有的卡槽相配合。
其中,所述盒体的另一侧边上设有防滑条。
由于采用上述技术方案,使用时,先将上盖的卡扣卡在卡槽内,铅笔旋转前行时被刀片切削下来的碎沫存入上盖与盒体上端面形成的腔体中,削完铅笔后,打开上盖,将切下来的碎沫倒进垃圾箱中即可,而且在盒体侧边上还设有防滑条,使用时容易拿牢,不能因用力不均滑落掉,因而具有结构简单,能防滑的,卫生的优点。
附图说明:以下结合附图和具体实施例来对本实用新型的技术方案做进一步说明。
附图是本实用新型的结构示意图。
具体实施方式:参考附图,一种旋转铅笔刀,在盒体1上端固有刀片2,一侧边设有铅笔口6,另一侧边上设有防滑条7,在盒体1上端设有向外凸起的上盖3,上盖3一端与盒体1铰接,另一端设有卡扣4与盒体上设有的卡槽5相配合。
