Description

注入式中性笔
技术领域
本实用新型涉及学习用具,特别涉及一种中性笔 
背景技术
中性笔逐渐取代钢笔和圆珠笔成为人们的所爱,但中性笔笔油不耐用,灌装麻烦,多为一次性使用,造成了不小的浪费。

本技术方案是这样实现的: 
一种注入式中性笔,包括笔杆1,笔帽2,笔头3,笔杆下端的笔萼4,笔萼上的加油孔5,笔杆上的加油孔6和笔帽上的透气孔7,其特征是笔杆在笔萼部分凹下一部分,加油孔6在笔杆的凹下部分上,笔萼4可绕笔杆1的凹下部分旋转。 
本实用新型的有益效果是: 
本申请摈弃了中性笔笔芯,直接单筒成笔,笔杆的粗度介于中性笔笔芯和普通中性笔笔杆之间,同时可注入笔油,从而方便了使用,杜绝了浪费,保护了环境。 
附图说明
图1是本实用新型结构图。 
具体实施方式
下面结合附图对本实用新型作进一步的描述,如图1所示一种注入式中性笔,包括笔杆1,笔帽2,笔头3,笔杆下端的笔萼4,笔萼上的加油孔5,笔杆上的加油孔6和笔帽上的透气孔7,其特征是笔杆在笔萼部分凹下一部分,加油孔6在笔杆的凹下部分上,笔萼4可绕笔杆1的凹下部分旋转。当笔萼4上的加油孔5旋转至与笔杆1凹下部分上的加油孔6上下连通时,即可进行注入式加油;加油完毕,旋转笔萼4,使加油孔5和加油孔6不再连通,即可进行使用。
