本实用新型的目的在于提供一种两用黑板擦,该黑板擦为棉刷、毛刷两用,给人们带来方便。 
本实用新型解决其技术问题所采取的技术方案是:一种两用黑板擦,包括黑板擦本体,其特征是,所述的黑板擦本体是由一个毛刷和一个棉刷插接构成;所述的毛刷包括刷把、两个侧面凸出条和刷毛,凸出条一端设有固定孔;所述的棉刷安在棉刷架上,棉刷架两个侧壁内侧设有凹槽,凹槽一端封闭,另一端通到棉刷架外面,凹槽通到棉刷架外面的一端设有固定开关。 
本实用新型的有益效果是:棉刷和毛刷可以插接或分离,更换灵活,使用方便,适于各种材质的黑板使用。 
附图说明
图1为本实用新型毛刷部分的结构示意图; 
图2为本实用新型棉刷部分的结构示意图。 
图中:1刷把,2刷毛,3凸出条,4棉刷架,5棉刷,6固定开关,7 固定孔,8凹槽。 
具体实施方式
如图1、图2所示。一种两用黑板擦,包括黑板擦本体,所述的黑板擦本体是由一个毛刷和一个棉刷插接构成;所述的毛刷包括刷把1、两个侧面凸出条3和刷毛2,凸出条3一端设有固定孔7;所述的棉刷5安装在在棉刷架上,棉刷架两个侧壁内侧设有凹槽8,凹槽8一端封闭,另一端通到棉刷架外面,凹槽8通到棉刷架外面的一端设有固定开关6。 
可以直接用毛刷擦黑板,要用棉刷5时,将棉刷5和毛刷插接,毛刷上的凸出条3和棉刷5上的凹槽8正好扣在一起,按下固定开关6,固定开关6正好插进毛刷的固定孔7内,棉刷和毛刷更换灵活,使用方便,适于各种材质的黑板使用。
