[0003] A document with prior art publication number CN205727412U provides a water-saving sprinkler specially designed for agricultural machinery. The sprinkler is provided with a water-saving device at the nozzle, so that the sprinkler saves more water and avoids waste during large-area sprinkler irrigation. A retractable bracket is provided on the base of the sprinkler. When it is necessary to move, the bracket can be shrunk and placed on a slot for easier movement. When irrigation is needed, the bracket can be lengthened to more fully irrigate the crops, making it more convenient to use.
