The utility model discloses a laminating sample clamp. The laminating sample clamp comprises a plurality of loose leaf pieces with the smooth surfaces and a binder clip for clamping a loose leaf book. The loose leaf pieces are provided with laminating adhesion areas, laminating samples adhere to the laminating adhesion areas and are composed of adhesive tape layers and laminating paper adhering to the inner sides of the adhesive tape layers, and paper labels adhere to the loose leaf pieces. The laminating sample clamp has the advantages that after laminating is finished on site, when the number of the laminating samples is large, the laminating sample clamp can be used as a carrier of the laminating samples, carrying is convenient, and the laminating samples can not be damaged; the laminating samples correspond to the labels in a one-to-one mode, so that mixing is prevented, and the loose leaf pieces can be increased or decreased according to needs; long-term and stable storage can be achieved, reading in the future can be convenient, the present and the past of the metallographic structure state of one metal work-piece can be contrasted conveniently, and retrospective study can be carried out conveniently.
