A sprinkler has a sprinkling device, and an inlet controlling device and an end cap respectively mounted on two opposite ends of the sprinkling device. The sprinkling device has a casing having outlet holes, and two regulating panels having regulating slots, two regulating wheels, two transmission rods and a cover having limit slots mounted on the casing. The outlet holes, the regulating slots and the limit slots respectively align with each other and are mounted around multiple nozzles. Turning the regulating wheels forces the nozzles to bend through the regulating panels so the sprinkler has a variety of sprinkling patterns to be suitable for every place where the sprinkler is placed. The nozzles are individually manufactured and are easily mounted on the casing and replaced.本發明係一種可調整噴水孔的灑水器，其包括有一出水控制裝置，該出水控制裝置係於一導水管設有一端蓋與一入水控制裝置，再於該導水管上依序設有二調整板、二旋鈕、二傳動件以及一上蓋，該導水管、每一調整板及上蓋上分別成型有相對應的孔洞，並於相對應的孔洞間分別穿設有噴管，使用者可分別移動該調整板，以推抵該噴管，進而變換各噴管的噴灑方向，由於各噴管分別受控於該二調整板，故可根據灑水器設置場所靈活地調整各噴管的噴灑方向。
