A spray nozzle device with a strike function is provided to initially separate a portion of each front end of protection films protecting a PCB(Printed Circuit Board) by jetting the strong compressed fluid like the compressed air or compressed water, to an object. The spray nozzle device(100) with a strike function for hitting a specific spot of an object by jetting the high-pressure compressed fluid comprises a hollow striking pipe(110) shaped like a fallopian tube having a lower side of a large diameter, provided with opened upper and lower sides, and formed with the predetermined length; a coupling(120) installed in the center of an upper end of the striking pipe and provided with a compressed fluid supply hole(122) feeding the compressed fluid supplied from a compressed fluid supply source; a flexible compressed fluid spraying hose(130) connected to the center of a lower end of the coupling at the predetermined length and rotating in the striking pipe by the compressed fluid jetted in feeding the compressed fluid through the compressed fluid supply hole to generate a strike effect by generating air impact force in the striking pipe; and weights(140) combined on the outer peripheral surface of the compressed fluid spraying hose at regular intervals.
