Abstract

一种伸长防护书夹,它包括两侧端的左立板、右立板,左立板、右立板同侧各连接有一侧板,两侧板相向且部分重叠;底板为长方形板,底板中部开有横向的导轨槽,左立板、右立板的底部固定连接有卡耳,卡耳嵌在导轨槽中并在槽中滑动,在导轨槽内左右两卡耳之间连接有拉簧。由于立板、侧板围成了一个三面封闭空间,其内置的书本稳定性增加,且左右立板由拉簧控制,可对书本产生一定的夹持力,防止书本倾斜散落。

Description

伸长防护书夹
技术领域
本实用新型涉及一种办公学习用品,特别是一种伸长防护书夹。
背景技术
普通的书夹由左右两只立板组成,立板的下方连接有水平的底板,使用时两立板间放置书本,这种书夹虽然多为铁制,但仍然较软,容易损坏。且这种书夹夹持力小,容纳的书本数量较少,放多了容易倾斜歪倒。
实用新型内容
本实用新型的目的是提供一种牢固且稳定性强的伸长防护书夹。
为实现上述目的,本实用新型的技术方案如下:
一种伸长防护书夹,它包括两侧端的左立板、右立板,立板下部连接有水平放置的底板,其特征在于:左立板、右立板同侧各连接有一侧板,两侧板相向且部分重叠;底板为长方形板,底板中部开有横向的导轨槽,左立板、右立板的底部固定连接有卡耳,卡耳嵌在导轨槽中并在槽中滑动,在导轨槽内左右两卡耳之间连接有拉簧。
由于立板、侧板围成了一个三面封闭空间,其内置的书本稳定性增加,且左右立板由拉簧控制,可对书本产生一定的夹持力,防止书本倾斜散落。
附图说明
图1为本实用新型的结构示意图。
具体实施方式
如图1所示,一种伸长防护书夹,它包括两侧端的左立板2、右立板4,立板下部连接有水平放置的底板1,左立板2、右立板4同侧各连接有一侧板,两侧板相向且部分重叠;底板1为长方形板,底板1中部开有横向的导轨槽5,左立板2、右立板4的底部固定连接有卡耳,卡耳嵌在导轨槽中并在槽中滑动,在导轨槽5内左右两卡耳之间连接有拉簧3。
