A water spray pistol includes a barrel, an elbow pipe fastened to the barrel, a pivoting seat fastened to the elbow pipe, and a nozzle head fastened to the pivoting seat. The pivoting seat is provided with a pivoting shaft and a locating pin. The nozzle head has a pivoting portion which is provided with a series of locating slots and an angle scale. The pivoting portion of the nozzle head is pivotally mounted on the pivoting shaft. As the pivoting portion makes a turn on the pivoting shaft, the locating pin of the pivoting seat is retained in one of the locating slots of the pivoting portion of the nozzle head, so as to locate securely the nozzle head. The angular adjustment of the nozzle head is measured by the angle scale of the pivoting portion.
