Description

铅笔书写定位套
本实用新型涉及一种文具用品,特别是一种能规范铅笔的握笔高度的书写定位套。
儿童初次用笔习字时,往往是从铅笔开始,但由于书写力度掌握不好,往往使手指的握笔位置越写越低,当正常视线被手指挡住后,只能歪头斜视,既影响视力,又难以练出一手好字,影响了写字教育的效果,更为严重的是这种不正确的握笔姿势一旦形成就难以纠正。
本实用新型的目的是为了帮助小学生克服握笔位置太低的不良习惯,设计一种适合铅笔使用的结构简单、装卸方便、互换性强、又能保护笔芯的铅笔书写定位套。
本实用新型根据铅笔在使用过程中不断被削短的特点,将铅笔书写定位套选用具有韧性和刚性的塑料制成套筒形,为了适合目前常用的外经稍有不同的六面体形或圆柱体形的铅笔通用,设计定位套的内径略小于铅笔外径,并在定位套的中上部开有一条伸缩缝,其特征在于定位套的下部设有定位圈,中部设有三个凹弧面,中上部开有一条伸缩缝,定位套的长度为30-35MM,内径为7-7.5MM。
附图1是本实用新型的结构示意图;
附图2是附图1的A-A向视图。
参见附图,图中的1是定位圈,2是凹弧面,3是伸缩缝。使用时,将定位套从铅笔下端套到已削好的铅笔上,露出铅笔斜面部分,写字时,手握定位套的三个凹弧面,此时,握笔的手指离笔尖约有3CM,符合规范要求,有利于帮助小学生克服握笔位置太低的不良习惯。使用后,将定位套前移,可防止笔芯折断。制造时,可用高密度聚乙稀和低密度聚乙稀混合后再加入色母料即可做出各种不同颜色的具有韧性和刚性的定位套。
本实用新型的铅笔书写定位套具有结构简单合理,装卸方便、互换性强、有利于规范握笔姿势,又能保护笔芯等优点,适合小学生广泛使用。
