Description

一种铅笔橡皮头调节器 
所属领域:本实用新型属文化用品,特别是一种铅笔橡皮头调节器。 
背景技术:现有的铅笔橡皮头,都是固定于铅笔端部,橡皮头不能随着其磨损而伸缩其长短,而且往往是铅笔还没有用完,橡皮已经没有了,这给使用带来了不方便。 
发明内容:本实用新型的目的是发明一种橡皮头能随铅笔的使用而伸缩其长短的铅笔橡皮头调节器。本实用新型是按如下的方式来实现的:本实用新型包括大套管,小套管和橡皮,小套管的外表面有螺丝槽,大套管的内表面有螺丝槽,二者相咬合,大套管随着拧动能在小套管的外面上下的滑动,从而实现对橡皮长短的调节,方便铅笔的使用。 
附图说明:图1为实用新型结构图    图2为橡皮结构图 
图1中:1、铅笔  2、橡皮  3、小套管  4、小套管外表面的螺丝槽  5、大套管  6、大套管内表面的螺丝槽 
图2中:1、橡皮  2、橡皮的底座 
具体实施方式:如图所示,本实用新型包括铅笔1,橡皮2,小套管3和大套管5,在小套管的外表面有螺丝槽4,大套管的内表面有螺丝槽6。使用时,橡皮2通过其底座固定在小套管3上,大套管5可以通过其螺丝槽6在小套管外面的螺丝槽4上做上下的滑动,从而实现对橡皮长短的调节,当橡皮不够用时,大套管向下滑动从而又滑出新的橡皮,实用方便。 

Claims (2)

1.一种铅笔橡皮头调节器,其特征在于:此项设计包括小套管,大套管和橡皮,小套管的外表面有螺丝槽,大套管的内表面有螺丝槽,二者相咬合,大套管可以在小套管的外表面上下拧动滑行,实现对橡皮长短的调节,橡皮通过其下部的底座卡在小套管内。
2.根据权利要求1所述的铅笔橡皮头调节器,其特征在于:所述橡皮的直径和小套管的外直径相同。
