Description

一种粉笔套
技术领域
本实用新型涉及一种粉笔套,具体的说是一种可以调节粉伸出笔长度的粉笔套。
背景技术
粉笔是日常生活中广为使用的工具,一般用于书写在黑板上。粉笔的成分是硫酸钙的一种白色沉淀物,不容易被分解,颗粒比粉尘大。因此在用粉笔书写时经常会把手弄脏,手上的粉笔灰误吸入还容易造成影响身体健康。后来出现一种粉笔套,可以防止脏手,但是这种粉笔套的伸出长度不能调节,因此使用很不方便。
实用新型内容
本实用新型的目的在于针对上述现有技术的缺陷和不足,为人们提供一种可以调节粉笔伸出长度的粉笔套。
为实现上述目的,本实用新型所采取的技术方案是:该粉笔套包括用于套装粉笔的壳体,壳体底部设置有滑块,在壳体侧壁开设有滑槽,在滑槽上活动安装有与滑块相连的推块。
所述壳体分为前半壳体和后半壳体,前半壳体和后半壳体相互扣装。
本实用新型套装于粉笔外侧,在用粉笔书写时不会脏手,通过推块能调节粉笔的伸出长度,在装粉笔时可以将壳体打开,装粉笔更为快捷,具有结构小巧、使用方便的优点。
附图说明
图1是本实用新型的结构示意图。
具体实施方式
如图1所示,本实用新型为一种粉笔套,它包括用于套装粉笔的壳体1,壳体底部1设置有滑块,在壳体1侧壁开设有滑槽2,在滑槽2上活动安装有与滑块相连的推块3。因此推动推块3就可以使滑块移动,从而调节粉笔的伸出长度。所述壳体1分为前半壳体和后半壳体,前半壳体和后半壳体相互扣装,便于粉笔的安装。
本实用新型套装于粉笔外侧,在用粉笔书写时不会脏手,通过推块3能调节粉笔的伸出长度,在装粉笔时可以将壳体1打开,装粉笔更为快捷,具有结构小巧、使用方便的优点。
