具体实施方式
为了便于本领域技术人员的理解，下面结合实施例与附图对本实 用新型作进一步的说明，实施方式提及的内容并非对本实用新型的限 定。
实施例一：
参考图 1至图 3， 一种新型文件夹， 包括底板 1、 扭簧 2以及通 过扭簧 2与底板 1枢接的勾架 3， 勾架 3的两端部之间设有夹持调节 装置， 夹持调节装置包括设有推块 41的转轴 4、 手柄 5和弹性件， 转轴 4与勾架 3固定连接， 勾架 3带动转轴 4转动， 手柄 5活动装在 底板 1上， 转轴 4与手柄 5相邻， 弹性件的两端分别顶住手柄 5和底 板 1 ; 在勾架 3打开的过程中， 转轴 4转动， 推块 41推开手柄 5直 至推块 41卡于手柄 5下方， 进而手柄 5在弹性件作用下复位， 压住 推块 41使得打开状态保持。
参考图 5和图 6， 本实用新型的弹性件的两端可分别与手柄 5和 底板 1相抵或连接。
本实施例中， 弹性件为压簧 6。 参考图 1和图 2， 为使推块 41在 配合手柄 5实现打开状态保持的功能的前提下，推动手柄 5时更加省 力， 手柄 5对应于推块 41的位置设有缺口。夹紧状态下， 推块 41容 置于缺口内； 在勾架 3打开的过程中， 转轴 4转动， 推块 41克服压 簧 6的作用力推开手柄 5直至推块 41穿过缺口， 最后卡于手柄 5下 方， 手柄 5在压簧 6作用力下复位， 进而手柄 5压住推块 41使得打 开状态保持。
参考图 1， 优选的实施方式是推块 41为方形， 使得转轴 4转动 时， 推块 41通过较大的推动面来推动手柄 5， 避免发生推块 41为三 角形容易产生的折断现象。
参考图 1至图 3， 本实施例中， 勾架 3设置成两端部对齐、 左右 对称的半围状， 夹持调节装置设于两端部之间， 拉开勾架 3时的力可 以平衡地施加至夹持调节装置。为使拉开勾架 3的操作更便利、安全， 勾架 3与底板 1之间局部留有间隙， 使用者从间隙处拉开勾架 3。
参考图 1至图 3，底板 1包括与勾架 3配合进行夹持的固定部 11 和从固定部 11延伸成型的安装槽 12， 扭簧 2嵌装于安装槽 12。此设 计使扭簧 2与外部隔离，避免扭簧 2在使用中与外部产生的相互破坏， 如刺破使用者的手指或外力强制拉开扭簧 2。扭簧 2—端铆接勾架 3， 另一端抵接安装槽 12的槽壁， 使得扭簧 2获得较大的支撑力。
参考图 3， 固定部 11还延伸成型有抵接部 13， 所述弹性件顶住 底板 1的一端具体地顶在抵接部 13上。 抵接部 13从固定部 11设有 安装槽 12的一端的中部延伸成型， 凸出于固定部 11并与固定部 11 处于同一平面， 抵接部 13可接触外界的边缘稍微圆滑地翘起， 避免 锋利的边缘划破接触物。
参考图 3和图 4， 手柄 5设有定位孔 51， 底板 1从抵接部 13延 伸成型有连接孔 131， 还设有贯穿定位孔 51和连接孔 131的插销 7。 插销 7使得手柄 5固定于抵接部 13上。 参考图 3， 连接孔 131通过 冲压成型， 抵接部 13被冲压部分形成通孔 132， 使用者可利用通孔 132把文件夹与外界固定， 如挂置在钉子上。
参考图 1至图 3， 所述手柄 5两侧部延伸分别成型有卡爪 52，两 个卡爪 52分别容置于安装槽 12与转轴 4间的间隙内。为转轴 4的组 装方便， 两个安装槽 12的间距大于转轴 4的长度， 卡爪 52—端顶住 安装槽 12， 另一端顶住转轴 4， 有效避免转轴 4在安装槽 12的间隙 内沿着卡块 31窜动。 同时， 也使得文件夹外观更美观。
参考图 1至图 3， 固定部 11设有用于与外界固定的固定孔 111。 本实用新型的文件夹可根据使用需求，通过固定孔 111固定于桌面或 者其他物体上。 参考图 3， 勾架 3端部设有卡块 31， 所述转轴 4端部设有与卡块 31匹配的卡口 42。 优选地， 卡块 31及卡口 42为多边形， 使得组装 后相互卡接得更牢固， 转轴 4可以跟随勾架 3转动。
参考图 4， 手柄 5朝外的一端为操作部 （图中未标示）， 本实施 例中， 远离转轴 4的一端为朝外。 操作部设有防滑紋 53。 防滑紋 53 凸设于手柄 5表面， 包括但不限于直线、 波浪线、 文字。
参考图 5， 操作部朝向底板 1的一端设有固定盲孔 54， 压簧 6— 端抵接在固定盲孔 54中， 另一端抵住抵接部 13。 优选的实施方式为 固定盲孔 54设于手柄 5的操作部， 使得按压夹紧调节装置的力可以 很好地传导至套在固定盲孔 54中的压簧 6。
实施例二：
实施例二与实施例一的区别特征在于： 弹性件为与手柄 5—体 成型的弹片 8， 弹片 8置于抵接部 13上。 参考图 6， 弹片 8的侧面和 底板 1接触。按压手柄 5后， 弹片 8抵住底板 1产生弹性力。 实施例 二的其它特征与实施例一相同， 在此不再进行赘述。
本实用新型的文件夹， 底板 1表面进行了防锈处理， 手柄 5优选 为硬度较强的塑胶材料制成。 关文件夹的正确的操作为按压操作部， 但误操作情况下， 如按压打开状态下的勾架 3， 文件夹也可关上， 而 不会对文件夹造成损坏。
以上内容仅为本实用新型的较佳实施例，对于本领域的普通技术 人员， 依据本实用新型的思想， 在具体实施方式及应用范围上均会有 改变之处， 本说明书内容不应理解为对本实用新型的限制。
