Improved swing water sprinkler adjustable in sprinkling angle

The invention discloses an improved swing water sprinkler adjustable in sprinkling angle. A dry type diverter and a dry type gear set are adopted, and gears of the gear set are Oerlikon gears and durable. A shift plate (598) with four shift plate elements (598t) externally sleeves each swing nozzle (59) of the swing water sprinkler adjustable in sprinkling angle, every two shift plate elements (598t) share a shifting gear with a handle, and the four shift plate elements (598t) of each shift plate (598) are sequentially provided with right shifting grooves and left shifting grooves in progressively increased inclination angle. The improved swing water sprinkler adjustable in sprinkling angle is perfected to be high in precision and accuracy, and the problems of difficulty in reversing, lability, low reliability and low accuracy in sprinkling angle regulation are solved. 改进的喷洒角度可调式摇摆洒水器是不通水的干式的换向器，所述齿轮组是干式的且齿轮组的齿轮是奥制的，故耐久；所述的喷洒角度可调式摇摆洒水器的每个摇喷头(59)的外面，分别依次套装有拨盘(598)的依次具递增斜倾角度的右拨槽和左拨槽，用四个拨盘(598t)，每两拨盘共用带手柄的调拨齿轮，四
