Description

可转动笔芯头圆规
技术领域
本实用新型涉及日常学习用品,尤其是一种可转动笔芯头圆规。
背景技术
工程制图时,需要用圆规画出粗细不同的线来表示不同意思,因而用现有的圆规需要画图过程中变换笔芯,这样不仅使用起来不方便,而且更换笔芯头会弄脏手指,从而弄脏图纸,费时且降低画图效率。
实用新型内容
本实用新型的技术任务是针对上述现有技术中的不足提供一种可转动笔芯头圆规,该圆规在圆规杆端部上设有橡皮和笔芯,能根据需要自由切换,方便使用。
本实用新型解决其技术问题所采用的技术方案是:可转动笔芯头圆规,其结构包括圆规本体,所述的圆规本体的一圆规杆的端部设有连接杆,所述的连接杆与圆规杆端部转轴连接,所述的连接杆的一端部设有笔芯头,另一端部设有橡皮。
本实用新型具有以下突出的有益效果:该可转动笔芯头圆规,在圆规杆的端部设有笔芯头和橡皮,可转动连接杆来切换,使用非常方便。
附图说明
图1是本实用新型的主视结构示意图;
图1中:1圆规杆,2转轴,3连接杆,4笔芯头,5橡皮。
具体实施方式1
如图1所示。可转动笔芯头圆规,其结构包括圆规本体,所述的圆规本体的一圆规杆1的端部设有连接杆3,所述的连接杆3与圆规杆1端部转轴2连接,所述的连接杆3的一端部设有笔芯头4,另一端部设有橡皮5。画圆时,转动连接杆3至笔芯头4到圆规杆1内侧,当要擦除所画的圆时,再转动连接杆3使橡皮5至圆规杆1内侧,方便省时的清除,可根据自己的需要来切换圆规头。
