[0024] A fixing seat 12 is fixedly installed on the outer wall of the circular base frame 1, and a fixing through hole is provided on the fixing seat 12. When the fixing seat 12 is fixed, the circular base frame 1 and the spray nozzle body 10 are also connected and fixed. The limiting assembly 5 includes a limiting block 501 fixedly installed on the outer walls of both sides of the U-shaped support plate 4, and a limiting screw 502 is threadedly connected to the limiting block 501. One end of the limiting screw 502 is connected to the first thread groove 2. After the U-shaped support plate 4 rotates, the user can make the limiting screw 502 screwed into the first thread groove 2 at the top of the circular base frame 1, and the U-shaped support plate 4 can be limited at this time.

[0025] The positioning assembly 7 includes an L-shaped seat 701 fixedly mounted on the top of the U-shaped support plate 4, a positioning screw 702 is threadedly connected to the L-shaped seat 701, a positioning plate 703 is fixedly mounted on one end of the rotating rod 6, a second thread groove 704 is arranged in a circular array on the positioning plate 703, one end of the positioning screw 702 is screwed into the second thread groove 704, after the rotating rod 6 drives the semicircular plate 8 and the spray nozzle body 10 to rotate, the user can screw one end of the positioning screw 702 into the second thread groove 704 on the positioning plate 703, and the positioning plate 703 and the rotating rod 6 can be positioned at this time.

[0026] The swing spray assembly 9 includes a swing mounting block 901 rotatably connected to the top center position of the semicircular plate 8, a positioning ring 902 is connected to the top of the swing mounting block 901, and the spray nozzle body 10 is arranged in the positioning ring 902.
