Abstract

本实用新型涉及指甲刀刀口,它将现有指甲刀的 平面弧线刀口改为异面弧线刀口,使之与人体手指甲 的表面和端面形状相近,从而增加了剪切宽度,消除 了平面弧线刀口在剪切时带来的不适感,特别适合于 儿童。本实用新型成本低,加工简单,易于批量生 产。

Description

本实用新型属于手工切削工具,特别涉及一种指甲刀刀口的改进。
目前,市场销售和日常生活使用的都是一种指甲刀刀口,其刀口为平面弧线刀口,它在使用时先将剪切部位的指甲压平因而产生不适和疼痛感;并且为了减轻不适感,不得不缩小剪切宽度,对儿童犹为不适。
本实用新型的目的是提供一种克服平面弧线刀口不足的异面弧线刀口。
本实用新型的目的通过以下技术方案来解决。在指甲刀两刀口接触相合部分,其特征是相合部位为异面弧线,即刀口可由两个异面的弧形柱面相交而成,该异面弧线与人体手指甲表面和端部形状相近。
本实用新型的结构具体由附图和实施例给出。
图1为本实用新型示意图,也作摘要附图。
如图所示的指甲刀刀口是将现有指甲刀的平面弧线刀口改造成的异面弧线刀口,在指甲刀两刀口接触相合部分3采用由两个异面的弧形柱面1、2相交而成,该异面弧线与人体手指甲表面和端部形状相近,以减轻和消除剪切指甲时压平指甲带来的不适和疼痛感,由于形状相似于人体指甲的弧度,所以剪切宽度也增加,特别适用于儿童。
本实用新型在现有指甲刀加工工艺上稍有改进,可将指甲刀作弧线运动,先由镗刀加工出与指甲表面弧度相近的部分,再由一薄片砂轮磨削出与指甲端部相近的部分。
本实用新型能消除因平面弧线刀口在剪切时产生的压疼和不适感,由于采用异面弧线刀口与人体指甲表面及端面弧度相近,因而增加了剪切宽度,提高了剪切效率,特别适用于儿童。
