Abstract

双锥卷笔刀由本体、削笔芯刀,削木杆刀、修磨 板、壳体及螺钉所组成。由于采用了双刀结构,卷削 后的笔芯可以任意长,又具有一定的强度。更重要的 是,可根据铅笔的材质,分别决定削笔芯刀和削木杆 刀的楔角,使卷削后的质量得以提高。
双锥卷笔刀的双刀旁附有修磨板,可以随意修磨 卷削和磨损后的笔芯。
该双锥卷笔刀卷削出的铅笔,外形美观、耐用,握 笔位置高,卷削次数少,修磨笔芯方便,对学生尤其是 工程制图人员更为适用。

Description

本实用新型涉及一种削铅笔的卷笔刀。
现有卷笔刀不论其外形如何,其基本结构是一把刀片紧固在锥孔槽旁。卷削出的铅笔木杆和笔芯外形是在同一园锥面上。露出的铅笔芯短而尖。这样一则使短而尖的笔芯很快磨损,于是就得频繁使用卷笔刀卷削。二则易使握笔位置偏低,遮住使用者的视线,尤其对制图者不便,故他们情愿使用刀片来削铅笔。
本实用新型的目的是提供一种双锥卷笔刀,使露出的笔芯长,又具有一定的强度,减少卷削的次数,还可以任意修磨笔芯。
本实用新型是这样实现的,双锥卷笔刀由本体,削笔芯刀,削木杆刀,修磨板、壳体及螺钉所组成。在本体的斜面上紧固有削木杆刀片,刀下有木杆锥孔。下方又紧固有削笔芯刀片,刀下有笔芯锥孔。使用时先卷削木杆,卷削时可随意决定笔芯的长度,然后再在笔芯锥孔内卷削笔芯。由于木杆锥孔不同于笔芯锥孔,所以卷削后的铅笔具有“双锥”的外形,此即“双锥卷笔刀”名称的由来。
在双刀的旁边还附有修磨板,卷削或磨损后的笔芯可在修磨板上根据需要进行修磨。
为了保持清洁,本体上有一半容积可用来存屑,待到一定程度,把本体从壳体内抽出,然后倒去积屑。
本实用新型由于采用了双刀结构,使卷削后的笔芯要多长有多长。更重要的是可分别选择合适的木杆刀片和笔芯刀片的楔角,使铅笔的卷削质量得以提高。本体上附有修磨板,可随意修磨笔芯,磨损后的笔芯不必马上卷削,修磨数次后,方需再卷,减少麻烦,节省时间。
下面结合附图,对本实用新型作进一步描述:
1、壳  体    2、修磨板    3、本  体    4、螺钉
5、木杆刀    6、螺  钉    7、笔芯刀    8、成型双锥的铅笔
参照附图,铅笔8被套入木杆刀5下的锥孔卷削,再在笔芯刀7下的锥孔卷削笔芯。如有需要可在修磨板2上修磨笔芯。
经使用,该双锥卷笔刀卷削出的铅笔,外形美观,耐用,握笔位置高,卷削次数少,修磨笔芯方便,对学生尤其是工程制图人员更为适用。
