The present invention relates to a sprinkler angle-adjustable sprinkler, and more specifically, a sprinkler angle-adjustable sprinkler to facilitate the adjustment of the sprinkling angle by allowing the direction changing unit to be installed by replacing the sprinkler with a sprinkler. It is about. The present invention is a hollow fastening guide sphere (100) coupled to the supply pipe (10) through which the liquid supplied to the crop flows； One side in the longitudinal direction is mounted to be exposed to the outside through the lengthwise lower side of the fastening guide sphere 100, the other side in the longitudinal direction is a hollow spin body 210 extending upwardly in the longitudinal direction of the fastening guide sphere 100 and , It is formed to extend in the upper direction from the upper end of the spin body 210, the guide shaft rod 220 with a cover hole 221 mounted on the upper end, and the guide shaft rod 220 in a spaced apart state A rotating body part 200 rotatably mounted on the fastening guide sphere 100, consisting of a wing striking body 230 branched from the outer periphery of the spin body 210 and extending to the cover sphere 221； The branch communication pipe 310 and the branch communication pipe 310, which are branched to the opposite sides in the state in which the spin body 210 and the interior of the rotating body portion 200 are in communication with each other, but are formed with fastening pieces 311 on the outer periphery ) Consisting of a sprinkling nozzle 320 that is detachably coupled to the end of the pair of sprinkling unit 300 to sprinkle water flowing through the supply pipe 10 to the side； The blade part 410 rotatably installed on the guide shaft rod 220 of the rotating body part 200, the striking rotating body 420 integrally formed on the wing part 410, and the striking rotating body ( 420) consisting of an operating heating piece 430 formed in a direction opposite to, and an elastic spring 222 mounted between the win
