Abstract

螺旋伸缩笔,由笔帽、定向块、笔体、笔芯、内螺旋杆组成,可适用各种型号的中性笔芯。

Description

螺旋伸缩笔
技术领域
本设计涉及一种书写工具,特别是一种螺旋伸缩笔。
背景技术
目前,一种中性笔体只有一种型号的中性笔芯适用,由于中性笔芯的长、短,粗、细不同,所适用的中性笔体也不同。
发明内容
针对中性笔体的不足,本设计提供了一种适用于各种型号的中性笔芯的螺旋伸缩笔。
螺旋伸缩笔,包括笔帽、定向块、笔体、笔芯、内螺旋杆,其中,笔帽与笔体卡槽式转动连接,内螺旋杆与笔帽螺纹连接,定向块与笔体固定连接,与内螺旋杆滑动连接,笔芯与内螺旋杆活动连接。
附图说明
图螺旋伸缩笔剖面结构示意图
具体实施方式
如图所示,笔帽1与笔体4卡槽式转动连接,内螺旋杆2与笔帽1螺纹连接,定向块3与笔体4固定连接,与内螺旋杆2滑动连接,笔芯5与内螺旋杆2活动连接;笔体4其余部分与现有的中性笔相同。
当中性笔芯5与笔体4不能适合时,转动笔帽1螺纹驱动内螺旋杆2沿定向块3上下运动,调节笔芯5使其适合于笔体4,这样,一种笔体可适用各种型号的笔芯。
