Description

活动式铅笔
本实用新型涉及铅笔技术领域,是一种只需更换笔芯的活动式铅笔。
目前,人们使用的各种铅笔,主要是传统的木制笔杆,它每年消耗大量的木材。最近几年新兴的纸杆铅笔,也需要消耗一定的木材。近几年铅笔的销售价随木材的价格上调而大幅上调。对于经济落后地区的学生来说,大量消耗木制铅笔是一种负担。另外,木制或纸制铅笔均需要刀片削出铅芯,这对于小学低年级的学生来说是一种不安全的操作,并易断铅芯,造成浪费。
本实用新型的目的是,提供一种活动式铅笔,它不采用木制或纸制笔杆,具有使用方便、节省木材的优点。
本实用新型的技术方案是,它有笔杆1,笔杆1上开有孔2,笔杆1的一端呈锥形,锥形处开有槽4,笔杆1锥形处安装紧固套3。笔杆的另一端安装笔塞5。
本实用新型的笔杆1可以采用塑料制作。本实用新型使用时,将铅芯穿出孔2后,采用紧固套3将笔杆1锥形处的槽4锁紧,将铅芯固定定位,便可使用。本实用新型只需更换铅芯,不需使用刀片。具有铅芯不易折断、使用方便、节约木材等优点。
附图说明:
附图1是本实用新型结构示意图。附图2是附图1中将紧固套3去掉后,笔杆1的外形图。
对照附图,对本实用新型做详细说明:图中1是笔杆,笔杆1上开有孔2,笔杆1的一端呈锥形,锥形处开有槽4,笔杆1锥形处安装紧固套3。笔杆的另一端安装笔塞5。本实用新型的各种部件均可采用塑料制作。可以降低铅笔的使用价格。
