Description

自动循环夹
【技术领域】
本发明涉及一种文具配件，具体的是涉及一种用于固定纸张的自 动循环夹。
【背景技术】
孔夹属于一种文具配件， 行业内一般称为活页夹、 圈夹。 对文件 保存稳妥安全， 文档翻转顺畅， 不会刮破文件， 勾嘴吻合无开口， 外 观高雅， 结构稳固， 不易刮花或凹陷， 整只夹强度加大， 不易变形。 孔夹一般包括长条形壳体、位于壳体内并被壳体卡紧的一对可枢转的 铰接板、 固定于铰接板上的半环元件， 这些半环元件可随着铰接板的 枢转运动而闭合或打开， 在闭合时， 两个铰接板上的相对应位置的两 个半环元件的末端抵靠在一起， 两个半环元件形成一个完整的钩环， 以便固定纸张及翻转纸张， 在打开时， 相对应位置的两个半环元件末 端分开， 以产生开口， 即可通过开口取出纸张或添加纸张。 目前市场 上孔夹的打开或闭合主要靠双侧手挚拔开两个半环元件以带动铰接 板控制开合张力， 这样需要一定的手力， 并且要双手同时操作， 手感 不适， 而且力度不均匀， 很容易破坏孔夹， 导致成本的增加， 当半环 元件内纸张数量比较多时， 用双手打开或闭合孔夹都很不方便。
