发明内容
针对现有的写不断自动铅笔易断芯以及使用时需要按动铅笔顶端的缺点。本实用新型提供一种免按、不易断芯的写不断自动铅笔。
为了实现上述目的，本实用新型所采取的措施是：一种写不断自动铅笔，包括笔杆10和笔头3，笔头3内从下沿上一直连接有笔嘴2，下档环4，上档环5，下弹簧6，夹件7，上弹簧8，套筒9，铅笔芯1依次沿以上组件的中心部位从上向下穿过，套筒9的顶端顶住上弹簧8的上端，夹件7内铅笔芯1的两侧边有两钢珠，两钢珠与铅笔芯1相接触，套筒9通过凸起91卡在笔头3上，笔头3通过螺纹与笔杆10连接。夹件7由两半组合而成。
本实用新型的有益效果：使用时不需要按动笔顶端，不易断芯。

具体实施方式
请参见附图说明其实施过程：
一种写不断自动铅笔，包括笔杆10和笔头3，笔头3内从下沿上一直连接有笔嘴2，下档环4，上档环5，下弹簧6，夹件7，上弹簧8，套筒9，铅笔芯1依次沿以上组件的中心部位从上向下穿过，套筒9的顶端顶住上弹簧8的上端，夹件7内铅笔芯1的两侧边有两钢珠，两钢珠与铅笔芯1相接触，套筒9通过凸起91卡在笔头3上，笔头3通过螺纹与笔杆10连接；夹件7由两半组合而成。当写完一段后，笔芯会自动向下运动一段距离，但是下降的距离是一定的，所以不会过长，不会导致笔芯写断。
