The invention discloses a tooling device for transferring graphene thin films used in a chemical vapor deposition method. The tooling device comprises a base plate, a fixing post, a lower fixture and an upper fixture which are fixedly connected with the base plate, wherein the lower fixture is a square concave block, holes are correspondingly formed in both sides of the concave block, the concave position facilitates an etching solution to inwards flow to etch catalytic substrates, the upper fixture is a square block which has the same length and width as those of the square concave block and holes are formed in the parts, corresponding to the square concave block, of the square block and can penetrate through the fixing post. By the tooling device, a plurality of catalytic substrates on which the graphene thin films grow can be simultaneously etched and thus the production efficiency is increased and meanwhile, the tooling device has the advantages of being simple in structure and easy to manufacture.
