NOVELTY - The utility model model claims graphene heat conduction fast, belonging to the technical field of pipeline. The utility model model comprises graphene capillary main body, graphene end of the capillary main body is sleeved and fixed with a first connection mechanism the other end is fixedly connected with a second connection mechanism the first connection mechanism graphene one of the main body is matched with the second connection mechanism the other graphene of the main body. The utility model is provided with a first connection mechanism and a second connection mechanism at two respectively of the main body graphene and by using the matching of the card and block cylinder, so as to finish the fixing of the pin shaft, at the same time, using the elastic action of the spring, the pin shaft is popped out from the cylinder, so as to facilitate the separation of the first connection mechanism and the second connection mechanism, which solves the problem that the existing bidirectional heat conduction is graphene and the splicing component is not convenient to splice and easy to lose.
