Swinging lawn sprinkler
First Claim
1. A swinging lawn sprinkler, including a sprinkling control unit made up of a gear-operated transmission mechanism, a limiting connector, a water inlet connector, a water outlet connector, a main driving wheel, and an adjusting seat;
- the present invention being characterized by that,a power switching device is mounted to a limiting cavity of the adjusting seat to activate the shift of angles of a flow switch plate thereby, and is equipped with a plurality of power units extending radially inwards on an inner side in linkage with a rotating shaft thereof, and a pair of limiting zones symmetrically protruding on the inner side of the power switch device, each of the pair of limiting zones having an elastic piece and a pressure guide member located therein, wherein one end of the pressure guide member is supported by the elastic piece and extends inwards and abuts against one side of a triangular locating guide block located in the limiting cavity of the adjusting seat;
wherein when the power switching device is rotated, the power units will bend until an auxiliary force is produced, deforming the elastic pieces and moving each of the pressure guide members past an obstructing side of the locating guide block.

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.
