Clamping piece composite structure

The utility model discloses a clamp assembling comprising at least two clamps; bunching band suit provides jointing two adjacent clamps, and when the two clamps are open, each end part of the bunching band is jointed with the outside of one clamp and the inside of the other clamp. Thereby the bunching band and clamp can nip file or other suitable articles, and when the two clamps are closed, they can be opened by thumbing from right to left or from left to right thus achieving better convenience and preferable integrity, stability, further the position of the bunching band can be changed when thumbing pages, which is interesting.
