The fastening unit is assembled with the inlet nozzle of the spray gun. The fastening unit is composed of the fastening bolt and the intermediate valve. In the spray can, the socket for combining with the fastening unit is formed. The spray can and the spray gun are coupled if the spray can is twisted after the adapter and the socket are combined. A collet is formed on the adapter. A cam is formed at the lower end of the intermediate valve. In the combining process of the spray gun and spray can, the collet is closely fixed to the inner surface of the outlet of the spray can by the cam.
