【技术实现步骤摘要】
一种防摔双写笔
本技术涉及文化用品领域,具体设计一种防摔双写笔。
技术介绍
笔,是人类的一项伟大专利技术,是供书写或绘画用的工具,多通过笔尖将带有颜色的固体或液体(墨水)在纸上或其他固体表面绘制文字、符号或图画,也有利用固体笔尖的硬度书写画图用铅笔和炭笔;当我们在记录内容或者做笔记时,常常需要利用不同颜色的书写笔将重点以及不同之处加以区分标注;但是在书写过程中,若要用别的颜色笔,需要更换其他书写笔,这个过程非常影响效率,有时甚至还需要到处找其他颜色的书写笔;此外,尤其是碳素笔,在书写时,特别容易摔地,而且在掉地的过程中,通常是笔尖朝下,导致笔珠非常容易损坏,有将近一半以上的碳素笔使用是由于笔掉地破坏笔尖,而非是油墨用完,这就造成很大的浪费,尤其在关键时刻,笔掉地上,损坏后,非常耽误事儿,给用户造成很大困扰。
技术实现思路
本技术的目的在于提供一种防摔双写笔,可以在笔中同时放入两只同种或者不同种颜色的笔芯,进行使用,换写方便快捷,只需将笔旋转180°即可完成;同时还能够大概率的防止双写笔掉在地上造成的笔头损坏,保证笔头不先着地,保护笔头。一种防摔双写笔,包括笔杆,后帽,笔头,笔芯,适应片;其特征在于所述笔头可拆卸的安装在笔杆上;所述笔杆顶部可拆卸的安装有后帽,且在笔杆与后帽之间设有适应片,适应片可以适用于两只不同长度的笔,使其被固定。笔头:所述笔头底部设有两个开孔;所述开孔中间设有螺纹孔,在螺纹孔内安装有弹簧;所述支柱固定端设有外螺纹,支柱顶着弹簧安装在螺纹孔内;所述支柱安装超出笔芯 ...
