One end of the drive shaft of the servo motor 3 is fixedly connected with a connecting shaft 6, and the connecting shaft 6 is fixedly connected with the inside of the rotating disk 4. The rotating disk 4 is movably sleeved with the inside of the fixed disk 5. The outer wall surface of the connecting shaft 6 is fixedly connected with a suspension arm 7. A water pipe 8 is fixedly connected inside the suspension arm 7. A water spray gun 9 is fixedly sleeved on the outer wall surface of the water pipe 8. The model of the water spray gun 9 is selected according to actual needs as long as it meets the work requirements. There is a positioning component on the top surface of the fixed disk 5 for positioning the rotation amplitude of the suspension arm 7. The positioning component includes: a plurality of fixed slots 10, all of which are opened on the top surface of the fixed disk 5. The distance between every two adjacent fixed slots 10 is thirty degrees. The inner bottom surface of the fixed slot 10 is fixedly connected with a first spring 11.
