Description

护手粉笔套
技术领域  本实用新型涉及一种教学用具。
背景技术  众所周知，教师在上课时粉笔是经常使用的用具，虽然现在已经出现了多媒体等方式的教学，但是板书仍然是教师上课广泛使用的方式，而教师在利用粉笔写板书时，手指直接接触粉笔，粉笔不仅容易弄脏手指，而且对手指皮肤造成损害。虽然现在已经出现了许多例如粉笔套等保护手指的器具，但是大多存在结构复杂、操作繁琐、制作成本高等缺点，另外，现有的保护手指的装置在功能上不能满足教师的使用需求。
发明内容  本实用新型的目的在于提供一种结构简单、方便实用、应用广泛、操作便捷、造价低廉的护手粉笔套。
本实用新型主要包括两个套管，即套管一，套管二；套管一为上开口管体，套管二为下开口管体；套管一的表面开设螺纹通孔一，固定螺栓一通过通孔一与套管一相连；套管二的表面开设螺纹通孔二，固定螺栓二通过通孔二与套管二相连；套管一的表面开设方形凹槽，凹槽内粘贴电子表。
本实用新型在使用时，将不同颜色的粉笔分别插入套管一和套管二内，利用固定螺栓固定即可；套管一表面的电子表便于使用者掌握时间。
本实用新型与现有技术相比具有如下优点：结构简单、方便实用、应用广泛、操作便捷、造价低廉。
附图说明  图1为本实用新型的立体示意简图。
具体实施方式  在图1所示的护手粉笔套的立体示意简图中，套管1-1为上开口管体，套管1-2为下开口管体；套管1-1的表面开设螺纹通孔2-1，固定螺栓3-1通过通孔2-1与套管1-1相连；套管1-2的表面开设螺纹通孔2-2，固定螺栓3-2通过通孔2-2与套管1-2相连；套管1-1的表面开设方形凹槽4，凹槽内粘贴电子表5。
