PURPOSE: Extinguisher head structure is provided to softly open a valve by dropping an elevating bar in pushing an actuating handle and to exactly measure pressure gauge by preventing supplying extinguishing liquid into a pressure inducing hole. CONSTITUTION: Extinguisher head structure comprises a fixed handle(126) mounted on an extinguisher; a center pin(122) installed on the extinguisher; an elevating bar(113) dropping or lifting while pressing an actuation handle(121); a valve(114) smoothly opened by a bushing(111); a discharging passage(104) mounted on a head(102); an upper screw unit(105) formed on an upper portion of the discharging passage by being connected to the bushing; a placing groove(106) inserting an end portion of the bushing; a packing(112) arranged on the placing groove; a dividing protrusion(110) formed between the placing groove and the upper screw unit; a pressure gauge(124) measuring pressure of extinguishing fluid contained in a tank(101); and a pressure inducing hole(109) connecting an end portion of a screw pipe(117) to an engaging hole(107).
