Description

伸缩笔
技术领域
本实用新型涉及一种文具,具体地说是一种书写笔。
背景技术
书写笔是学生在学习过程中常常使用的文具之一,可换笔芯的圆珠笔是现在使用较为广泛的一种书写笔。但是现有的圆珠笔在换笔芯的时候,只能换用同规格同长度的笔芯,其他类型的笔芯不能够通用,给使用者造成了不便和浪费。
实用新型内容
本实用新型的目的在于提供一种伸缩笔,主要解决圆珠笔无法兼容不同长度笔芯的问题,该伸缩笔通过可调整的套管来适应不同笔芯的长度,方便快捷。
本实用新型解决其技术问题所采取的技术方案是:伸缩笔,其结构包括笔管和套管,所述的套管为上端封闭底端开口的圆柱空腔体,笔管设置在套管空腔内,所述的笔管外壁对应两侧分别纵向垂直设置有若干个凹槽,套管开口处内侧壁对应两侧分别设置有一凸起,所述的凸起分别卡放在笔管外壁的凹槽内,所述的笔管内设置有笔芯。
本实用新型的有益效果是:使用者能够根据笔芯长度的不同,将套管上的凸起与笔管外壁两侧的一组凹槽配合,调整成适合的长度,凹槽与凸起的相互配合能够将套管与笔管固定在一起,正常书写时,凸起与凹槽能够可靠固定,确保书写顺畅。
附图说明
图1为本实用新型的结构示意图;
图中:1套管,2笔芯,3笔管,4凹槽,5凸起。
具体实施方式
如图1所示。伸缩笔,其结构包括笔管3和套管1,所述的套管1为上端封闭底端开口的圆柱空腔体,笔管3设置在套管1空腔内,所述的笔管3外壁对应两侧分别纵向垂直设置有若干个凹槽4,套管1开口处内侧壁对应两侧分别设置有一凸起5,所述的凸起5分别卡放在笔管3外壁的凹槽4内,每对应的两个凹槽4为一组,所述的笔管3内设置有笔芯2。
使用者能够根据笔芯2长度的不同,将套管1上的凸起5与笔管3外壁两侧的一组凹槽4配合,调整成适合的长度,凹槽4与凸起5的相互配合能够将套管1与笔管3固定在一起,正常书写时,凸起5与凹槽4能够可靠固定,确保书写顺畅,只有在使用者对套管1施加外力的情况下,凸起5才能够脱开凹槽4。
