Description

旋转笔
技术领域  本实用新型涉及一种笔,尤其是能够根据需要改变长度的旋转笔。
背景技术  笔是人们常用的一种学习、办公用品。较长的笔往往携带不便,较短的笔则在使用时不好把握。
中国专利CN2202645号所公开的“具有趣味性的旋转笔”专利(申请号:CN94219379.2),包括上下段皆为可旋动的笔管,上笔管内嵌置有一旋动管,该旋动管的内管壁设有螺旋槽,供制动一固定管内的升降管及一笔芯的旋转,使该升降管及笔芯先后分别产生旋动,进而能将笔芯凸出或将饰物凸出,达到书写与愉乐为一体之目的。这项专利的不足之处在于:该升降管及笔芯先后分别产生旋动,进而能将笔芯凸出或将饰物凸出,达到书写与愉乐为一体之目的,但没有明显改变笔的长度,因而并没有解决笔的长短问题。
发明内容  本实用新型的目的就是要提供一种结构简单、使用方便的旋转笔,在满足正常使用的同时,让笔可以根据需要改变长度。
为了达到上述目的,本实用新型提供的旋转笔包含笔筒、笔杆、笔尖、笔帽,其中,笔筒的内表面和笔杆的外表面有螺纹,且相互配合。本实用新型使用时,将笔杆从笔筒中旋转出,笔杆和笔筒的共同长度便可满足书写需要;不用时,将笔杆旋转进笔筒中,便可缩短整个笔的长度,方便携带。
本实用新型提供的旋转笔具有积极的效果:包含笔筒、笔杆、笔尖、笔帽,其中,笔筒的内表面和笔杆的外表面有螺纹,且相互配合,结构简单;使用时将笔杆从笔筒中旋转出,笔杆和笔筒的共同长度便可满足书写需要,方便使用;不用时将笔杆旋转进笔筒中,便可缩短整个笔的长度,方便携带。
附图说明  本实用新型将结合附图作进一步的说明,请参看附图:
附图1表示本实用新型的示意图。
附图1所示的结构包括:笔筒(1),笔杆(2),螺纹(3),笔尖(4),笔帽(5)。
具体实施方式  本实用新型提供的旋转笔包含笔筒1、笔杆2、笔尖4、笔帽5,其中,笔筒1的内表面和笔杆2的外表面有螺纹3,且相互配合。本实用新型使用时,将笔杆2从笔筒1中旋转出,笔杆2和笔筒1的共同长度便可满足书写需要;不用时,将笔杆2旋转进笔筒1中,便可缩短整个笔的长度,方便携带。
本实用新型保护范围涉及上面所述的所有变化形式。
