发明名称 Paper clip
摘要 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.
