ABSTRACT:
A swinging lawn sprinkler including a sprinkling control unit with a gear-operated transmission mechanism attached to one side of a sprinkler mount. A limiting connector having a water outlet connector engaged at one side is correspondingly matched to the gear-operated transmission mechanism and a spraying member. A main driving wheel, an adjusting seat, and a water inlet connector are sequentially coupled at the other end of the gear-operated transmission mechanism. The adjusting seat is equipped with a limiting cavity for a power switching device made up of a plurality of power units in linkage with a pivoting shaft and a pair of limiting zones with elastic pieces and pressure guide members adapted to be pivotally mounted to activate the shift of angles of a flow switch plate.
