A swinging lawn sprinkler includes a sprinkling control unit with a gear-operated transmission mechanism adapted therein attached to one side of a sprinkler mount thereof. 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 thereof. The adjusting seat thereof 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 therein to be pivotally mounted therein to activate the shift of angles of a flow switch plate thereby. Thus, when the power switching device is rotated, the power units will produce arc-shaped stress concentration in advance and store energy thereby till an auxiliary force is instantaneously formed to overpower the elastic pieces and send the pressure guide members thereof quickly over to the other side of triangular locating guide blocks of the adjusting seat thereof, efficiently shortening the moving course of the pressure guide members and the elastic pieces thereof, and facilitating the swing of the spraying member within a short period of time sa as to increase the frequency of the variation of water flow for more thorough and equal sprinkling of water around the lawn in a short time.
