A spray gun assembly structure comprises a connecting tube having a first coupling head connected to water supply and a second coupling head mounted to a spray gun. A coupling shaft of the second coupling head defined by at least two annular grooves is mounted into the spray gun and positioned via a locking tube. Multiple waterproof rings are adapted to the annular grooves to abut tight against the internal surface of the spray gun, forming a dual water-sealing benefit and permitting the spray gun to achieve accurate water shutoff state no matter under high or lower water pressure. A stop flange disposed beneath the coupling shaft is enclosed between the spray gun and the locking tube. Therefore, with the extension and twist of the spray gun, the coupling shaft and the stop flange can be rotated and automatically adjusted in position, facilitating stable and easier handling and operation thereof.
