NOVELTY - The utility model is new type relates to the graphene preparation technology field, especially relates to one kind multiplication type prepared graphene and clamp, the clamp comprises two of supporting frame and several horizontal supporting rod, two of the supporting frame relative and parallel set, said horizontal supporting two end rod respectively and the two supporting frame of the upper fixing part, several said horizontal support rod mutually parallel and uniform gap is horizontal set, several said horizontal support rod are vertical at two of the supporting frame. The utility model is new type of beneficial effect is: multiplication type growing graphene and the utility new type with bracket, structure is simple, easy to process, low cost, and easy sampling, mass production of graphene sample fit for industrial production, and growing process of metal catalyst does not generate fold, greatly increase alkene production and qualified rate, and small square meter of fit.
