Abstract

一种能够方便、快速并且铅芯不易被削断的卷笔刀,它是在已有的卷笔刀刀架反面增加一片刀片、固定螺钉。使刀片、螺钉、刀架、螺钉、刀片顺序组成,并且正、反面刀片安装位置相同且相互对称。在削铅笔时,笔尖的木制和铅芯部分受正、反两片刀同时切削,铅芯受两片刀正、反方向力作用,使铅芯卷削时受力平衡,则铅芯不易被折断。达到卷削铅笔时快速、不断铅芯的目的。

Description

双刀型卷笔刀
本实用新型涉及一种方便,快速削铅笔用的卷笔刀装置。尤其是能在卷削铅笔时不会削断铅芯的卷笔刀。
目前:公知的卷笔刀构造是由刀架,一片刀片,连接螺钉组成。卷削铅笔时,笔尖的木制和铅芯部分受一片刀片切削,铅芯单向受力,由于铅芯抗折强度较低,故卷削铅笔时容易折断铅芯。
木实用新型的目的是提供一种双刀片型卷笔刀,它不仅能卷削出外观漂亮的铅笔,而且能快速不易削断铅芯。
本实用新型的目的是这样实现的,在刀架上正面由刀片、螺钉。反面由相同刀片、螺钉等组成,并且正反面刀片安装位置相同并且相互对称。在削铅笔时,笔尖的木制和铅芯部分受正、反两片刀同时切削,铅芯受正、反两片刀同时切削,铅芯同时受两片刀正、反方向力作用,达到铅芯切削时受力平衡,则铅芯不易被拆断。达到卷削铅笔快速不断铅芯目的。
由于采用上述方案,在卷削铅笔时,采用了铅芯在卷削中受力平衡原理。结构上只在原卷笔刀基础上增加一片刀片,一个固定螺钉。
下面结合附图和实施例对本实用新型进一步说明。
图1是双刀型卷笔刀实施例的正、反面平面结构图。
图2是双刀型卷笔刀实施例的右侧面结构图。
图3是图2的I-I剖视图。
图中:1、刀片2、螺钉3、刀架。
在图1实施例中,刃片(1)、螺钉(2)在刀架(3)的一侧连接,反面为相同连接顺序。
在图2实施例右侧面图,刀架(3)两侧由刀片(1)组成。
在图3实施例1-1剖视图中,刀片(1)、螺钉(2)、刀架(3)、刀片(2)、螺钉(1)连接。
