Description

一种握粉笔器
技术领域
本实用新型属于教学用具领域,涉及一种握粉笔器。 
背景技术
教师通常使用粉笔在黑板上书写板书,一些粉笔末经常会留在教师的手上,严重污染了教师手指的皮肤。 
实用新型内容
本实用新型的目的在于克服现有技术的不足,提供一种结构简单的握粉笔器。 
本实用新型解决其技术问题是通过以下技术方案实现的: 
一种握粉笔器,包括粉笔,所述握笔器为一个椭圆形结构,该椭圆体同轴制有一安装粉笔的通孔,该通孔的直径小于粉笔的直径,在椭圆体的上部外缘对称制有一手指凹槽。 
而且,所述握笔器的材料为具有弹性的橡胶。 
本实用新型的优点和有益效果为: 
本握粉笔器为一椭圆体结构,该椭圆体同轴制有一安装粉笔的通孔,在椭圆体的上部外缘制有一对称的手指凹槽。本实用新型设计科学合理、结构简单,粉笔安装在通孔内部,使教师容易握住粉笔且不易打滑,同时解决了粉笔污染教师手指的问题。 
附图说明
图1为本实用新型的主视图。 
具体实施方式
下面结合附图、通过具体实施例对本实用新型作进一步详述,以下实施例只是描 述性的,不是限定性的,不能以此限定本实用新型的保护范围。 
一种握粉笔器,该握笔器2为一个椭圆形结构,该椭圆体同轴制有一安装粉笔的通孔4,该通孔的直径小于粉笔1的直径,在椭圆体的上部外缘对称制有一手指凹槽3。 
所述握笔器的材料为具有弹性的橡胶。 
在使用该握笔器时,先将粉笔从握笔器的下部向上安装,使粉笔上部伸出,即可以使用;如果粉笔端部较短,直接用手将其向前端拔出。因粉笔与通孔为过盈配合、且书写板书时使粉笔与握笔器之间连接的更加紧密,从而粉笔不会脱落。 

Claims (2)
