Description

插接式铅笔
本实用新型属于书写用具,具体涉及一种插接式铅笔。
通常小学生在使用铅笔时,当用到只剩下5-6厘米左右,已经很难握持;若勉强用之,既不方便书写,又使儿童下意识地靠近桌面,长此下去,对儿童的视力健康带来不良影响。据初略统计,全国由于此原因每年丢弃的废铅笔头就达数万吨,造成木材资源的巨大浪费。
本实用新型的目的就是提供一种使短铅笔头握持方便,并使其全部得到充分利用的插接式铅笔。
为达到上述目的,本实用新型采用下述方案:
1.将铅笔的笔头、笔尾分别加工成互相匹配并可互相插接的凸状或凹状;
2.设置与上述铅笔配套使用的加长杆,将杆的一端加工成与上述笔尾形状相匹配并可插接在此部位的凹状或凸状;
所述凸状或凹状部分可分别加工成相匹配的螺纹或齿条、齿槽,使其结合更紧密、更牢固。
当所使用的铅笔只剩下7-8厘米,不太方便握持时,在其笔尾部插接上述加长杆,一般加长杆的长度约8-10厘米,此时,如同一支新的铅笔那样容易握持,便于书写。为方便学生使用,该加长杆的另一端可装上橡皮擦。
当上述铅笔使用至只剩下2-3厘米左右时,取下加长杆,换上一支笔头与此笔尾相匹配的新铅笔。如此反复,使每支铅笔都能完全使用,避免了浪费。
本实用新型结构简单,使用方便,既节约木材资源,又能有效地保护少儿视力及身心健康!
下面结合附图详述本实用新型的实施例:
图1是本实用新型实施例的结构示意图;
图2是本实用新型另一个实施例的结构示意图;
图3是本实用新型中加长杆的一个实施例;
图4是本实用新型中加长杆的另一个实施例。
图1中,笔头1加工成螺杆状,笔尾3加工成螺母状;图2中,笔头1加工成齿条状,笔尾3加工成齿槽状;图3图4中,加长杆的一端加工成与上述笔尾3相匹配的螺纹或齿条;当图1或图2中的铅笔使用至5-6厘米时,将图3或图4中加长杆的端部4与图1、图2中笔尾插接;当铅笔使用至2-3厘米时,取下加长杆,以同样结构的新铅笔的笔头与此笔尾部插接,如此反复;从而实现本实用新型之目的。
