The present invention is an improved paper clip, which is applied on different thicknesses of documents, even only one single paper. 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 with a sunken slot; the second clipping piece consists of a bending curve part and a horizontal part, a bottom curve surface of the bending curve part protrudes into the sunken slot and is roughened to become a rough surface for increasing friction to tightly clamp documents or one paper; the support beam, first clamping piece and second clamping piece form a capacity to store thicker documents.
