Description

一种多功能自动铅笔
技术领域
本实用新型涉及一种自动笔,具体地说是一种多功能自动铅笔。
背景技术
同学们在画圆时需要用到圆规,但是当手边没有圆规时,很难将圆形画得规范,普通的笔上不带有圆规,不具备帮助同学们画出标准圆形的功能。
实用新型内容
本实用新型的目的在于提供一种多功能自动铅笔,该多功能自动铅笔平时可以当自动笔写字,在使用圆规的时候可以用来当圆规使用。
本实用新型解决其技术问题所采取的技术方案是:一种多功能自动铅笔,包括自动笔本体,所述的自动笔本体的笔管底端为笔芯,笔管顶端为铅芯按压钮,其特征是,所述的笔管外壁上半部设一沿笔管轴线方向的凹槽,凹槽顶端设一转轴,支腿上端与转轴铰接,支腿下端设有固定针,支腿中部设一连接轴,连接轴一侧设有限位块。
本实用新型的有益效果是:由于在笔管上部的凹槽内,叠放一圆规支腿,既可以当自动笔又可以当圆规,使用方便,便于存放。
附图说明
图1为本实用新型的结构示意图。
图中:1笔管,2笔芯,3铅芯按压钮,4支腿,5转轴,6连接轴,7限位块,8凹槽。
具体实施方式
如图1所示。一种多功能自动铅笔,包括自动笔本体,所述的自动笔本体的笔管1底端为笔芯2,笔管1顶端为铅芯按压钮3,所述的笔管1外壁上半部设一沿笔管轴线方向的凹槽,凹槽顶端设一转轴5,支腿4上端与转轴5铰接,可绕转轴5旋转,支腿4下端设有固定针,支腿4中部设一连接轴6,连接轴6将支腿4一分为二,支腿4下部可旋转180度,连接轴6一侧设有限位块7,当支腿4为一条直线时,限位块7起到限位作用。
平时支腿4下部向上翻折,置于凹槽内,不影响同学们用多功能自动铅笔写字,当需要画圆时,向外侧拉动支腿4,将支腿4的固定针向下旋转,限位块7可使支腿4保持垂直,以固定针为支点固定在纸上,用自动铅笔的笔芯画圆。
