NOVELTY - The utility model claims a special slot for computer application, comprising a graphene film and a slot installed on the main board; two sides of the slot length direction are equipped with a shell; the upper part of the slot socket is provided with a cover plate; the shell is provided with a scroll; two ends of the scroll are installed in the inner ring of the clockwork spring; the top surface of the shell is provided with a strip-shaped port; the middle of the graphene film is installed on the surface of the cover plate; two ends of the graphene film are bent downwards; and they are wound on the scroll through the strip-shaped opening. The utility model has simple structure; the cover plate is covered on the upper end of the slot automatically through the torsion of the clockwork spring; the dust is prevented from entering; when in use, the cover plate can be lifted, the graphene film is pulled out; after the hardware is inserted into the slot, the cover plate can be propped against the hardware; and the hardware can be pressed by the torsion of the clockwork spring; the connection firmness of the hardware and the slot is increased.
