Spraying irrigation nozzle having adjustable and automatic angle and outlet automatic extension

The utility model relates to a spray head for sprinkling irrigation with adjustable and automatic angle of torsion and an automatic telescopic water jet, using a water-flow driving system which is composed of a connecting disk, a rotating rod, a water wheel, a steel ball, a current plate, a pawl cam, a shifting rod, etc., and adjusting the clamped position of the pawl cam on the rotating rod and the splicing position of a filtering net on the connecting disk to obtain reciprocating automatic angle and speed of torsion desired by the water jet; when sprinkling irrigation is started, the utility model uses water pressure to realize the automatic elevation of the water jet; when the sprinkling irrigation is stopped, the water jet can be automatically retracted into an inner cavity. The utility model is suitable for being arranged at the rim angle of a land block to carry out the sprinkling irrigation in any determined angle and speed of torsion.
