    • The present invention relates to an improved paper clip which is suitable for holding documents of different thicknesses. The improved paper clip includes three elements, which are a first clipping piece, a second clipping piece and a support beam. The first clipping piece is formed with a sunken slot therethrough and is connected to a bottom side of the support beam. The second clipping piece has a bending curve part and is connected to a top side of the support beam. The bending curve part is partially protruding into the sunken slot and is roughened to become a rough surface for increasing friction to tightly clamp documents. The inner surface of the support beam is a flat plane so as to provide a guiding function when the document is received between the first and second clipping pieces. The first and second clipping pieces are both adjoined to the inner surface of the support beam, such that the outer surface of the support beam substantially forms part of the outer contour oft the paper clip.
    • 本发明涉及一种适合于保持不同厚度的文件的改进的回形针。 改进的回形针包括三个元件,它们是第一夹持件,第二夹紧件和支撑梁。 第一夹持件形成有穿过其中的凹槽,并且连接到支撑梁的底侧。 第二夹持件具有弯曲曲线部分并且连接到支撑梁的顶侧。 弯曲曲线部分部分地突出到凹槽中,并且被粗糙化以变成粗糙表面,以增加摩擦力以紧紧夹紧文件。 支撑梁的内表面是平面,以便当在第一和第二夹持片之间接收文件时提供引导功能。 第一和第二夹持件都毗邻于支撑梁的内表面,使得支撑梁的外表面基本上形成回形针的外部轮廓的一部分。
