A novel pistol nozzle is provided herein, in which a spherical valve having a through hole is used to control the water flow by the alignment of the through hole to the water channel of the pistol nozzle. The alignment of the spherical valve's through hole is controlled by the interaction of a pinion and a gear when the control lever of the pistol nozzle is grasped, which requires less effort and achieve more precise control to the water flow.
