[0002] With the development of agricultural technology and the increasing scarcity of water resources, traditional manual irrigation methods are inefficient, resulting in serious water waste. Highly efficient and precise irrigation technologies, such as sprinkler and drip irrigation, are gradually becoming the development direction of water-saving technologies. Adjustable irrigation sprinklers are spraying devices that can adjust the spray range. They typically contain one or more movable or deformable parts to adjust the spray characteristics according to different application needs. Currently, the main body of adjustable sprinklers generally changes the spray channel through a rotating adjustment block to achieve different coverage areas to adapt to specific irrigation or cleaning needs. However, the structure is relatively complex and inconvenient to use. Utility Model Content
