Abstract

一种笔尖自动缩回笔,主要包括笔杆、笔芯以及笔头,在笔杆底端侧壁开设开口,在开口上方笔杆表面开设滑道,滑道处安装滑块,且滑块与开口大小、形状一致;笔芯插入笔杆内,在笔芯上套有弹簧,弹簧上端设有金属圈套住笔芯,金属圈通过弹性金属片与滑块连接,金属圈底面与弹簧连接,弹簧底端连接在笔杆底端管口处。本实用新型具有结构合理、功能奇特、使用方便等优点。

Description

笔尖自动缩回笔 
技术领域     
本实用新型涉及一种学习用品,尤其是书写工具。 
背景技术    
 从古至今,笔一直都是人们学习工作中最重要的书写工具。但是,曾有和现有的笔虽然种类很多,但是无论哪种笔都存在缺陷。目前,市场上只有两种笔,一种是笔尖始终露在笔杆外部,另一种是笔尖只有在使用时才露在外部。对于这两种笔来说,人们在书写过程中,一旦笔从手中脱落,笔尖依然露在外部,也因此很容易造成笔尖断裂破损,依然会给人们带来不便。 
发明内容    
 本实用新型的目的是提供一种当笔脱离手指时笔尖便会自动回缩的笔尖自动缩回笔。 
本实用新型主要包括笔杆、笔芯以及笔头,在笔杆底端侧壁开设开口,在开口上方笔杆表面开设滑道,滑道处安装滑块,且滑块与开口大小、形状一致;笔芯插入笔杆内,在笔芯上套有弹簧,弹簧上端设有金属圈套住笔芯,金属圈通过弹性金属片与滑块连接,金属圈底面与弹簧连接,弹簧底端连接在笔杆底端管口处。 
书写使用时,使用者顺着笔杆滑道向下滑动滑块,用滑块堵住笔杆表面的开口,此时滑块带动弹性金属片下移,弹性金属片带动弹簧压缩并把笔芯下移,使得笔尖从笔杆底端伸出,使用者用手指压住滑块和笔杆便可正常书写。当松手时,弹簧向上弹起并利用弹性金属片把滑块从开口处顶开,使得滑块顺着滑道向上移动,此时笔芯上移,笔尖从笔杆底端开口处缩回。 
与已有技术相比,本实用新型的有益效果为:结构合理、功能奇特、使用方便,可保护笔尖安全,避免笔杆掉落后对笔尖的损伤。 
附图说明  
   图1为本实用新型的刨面图。 
具体实施方式 
    在图1所示的本实用新型的立体结构简图中,主要包括笔杆1、笔芯2以及笔头3,在笔杆底端侧壁开设开口4,在开口上方笔杆表面开设滑道5,滑道处安装滑块6,且滑块与开口大小、形状一致;笔芯插入笔杆内,在笔芯上套有弹簧7,弹簧7上端设有金属圈套住笔芯,金属圈通过弹性金属片8与滑块连接,金属圈底面与弹簧连接,弹簧底端连接在笔杆底端管口处。
