Abstract: The present invention provides a high-pressure water sprayer for fire extinguishment, including a body having a base and a fluid conduit connecting thereto, and at least two spray heads and fluid-guiding bars respectively corresponding thereto. The base is provided with at least two positioning slots for positioning the spray heads. Each of the positioning slots communicates with a main fluid passage within the fluid conduit via a branched fluid passage. A nozzle is formed at a lower end of the spray head, and an orifice is formed at an upper end of the spray head for the fluid-guiding bar to be disposed in a receiving space within the spray head. Then the receiving space communicates with the nozzle. A lower end of the fluid-guiding bar is provided with fluid-guiding grooves opposite to the nozzle. The spray heads are arranged in at least two different disposed angles. An appropriate spray angle can be obtained by adjusting the angle between the nozzle and the base.
