[0035] The first end of the mounting bracket 210 is rotatably connected to the frame 400, and the second end is freely extended upward. The nozzle 100 is arranged at the second end of the mounting bracket 210 and can rotate with the rotation of the mounting bracket 210. The driving member 220 is arranged on one side of the mounting bracket 210, and the driving member 220 is rotatably connected to the frame 400, and the rotation center line of the driving member 220 intersects and is perpendicular to the mounting bracket 210. The first end of the swing bracket 230 is hinged to the mounting bracket 210, and the hinge center line of the first end of the swing bracket 230 intersects and is perpendicular to the rotation center line of the mounting bracket 210. The second end of the swing bracket 230 is connected to the driving member 220 and can rotate with the rotation of the driving member 220, and the distance between the second end of the swing bracket 230 and the rotation center line of the driving member 220 is adjustable, so that the purpose of changing the swing angle of the swing bracket 230 can be achieved by changing the distance between the second end of the swing bracket 230 and the rotation center line of the driving member 220, thereby achieving the purpose of changing the spraying range (i.e., the swing angle) of the nozzle 100.
