Description

粉笔套
技术领域  本实用新型涉及一种教学用品,尤其是一种粉笔套。
背景技术  众所周知,粉笔是目前学校教学中最重要的书写工具。但是,当粉笔用至较短时,人们无法稳固的握住粉笔,也因此无法继续书写,只能把这些粉笔头扔掉,结果造成严重的浪费。为了解决上述问题,我们提供了一种可有效利用粉笔头的粉笔套。

为达到上述目的,本实用新型粉笔套,包括插管,在插管外部固接清洁刷,插管表面开设螺纹透孔,在透孔处插入限制杆,且限制杆插入端为弧形结构。
采用上述结构后,使用时,使用者把粉笔头安插在插管内,然后向内旋转限制杆,利用限制杆紧紧顶住粉笔头并保持粉笔头在插管口有伸出端,此时,使用者手握插管,利用粉笔头书写字迹;修改粉笔字时,使用者握住清洁刷,利用清洁刷擦拭粉笔字。
与已有技术相比,本实用新型的有益效果为:外形精美、工艺简单、操作灵活,可节省粉笔,并能快速擦拭粉笔字,提供便利的教学书写条件。
附图说明  图1为本实用新型粉笔套的整体结构示意图。
图中标号:1为插管、2为清洁刷、3为透孔、4为限制杆。
