[0019] As the instruction manual Figure 1 , 3 As shown, the telescopic spraying mechanism 6 includes an extension arm 1 61, an extension arm 2 62 and an extension arm 3 63 which are plugged together in sequence, and the longitudinal sections of the extension arm 1 61, the extension arm 2 62 and the extension arm 3 63 are all rectangular frame structures, and the lower ends of the extension arms 1 61, the extension arms 2 62 and the extension arms 3 63 are each provided with at least one spraying head 64.

[0020] Both sides of the frame body 1 are provided with ear plates 13 arranged opposite to each other, one end of the extension arm 1 61 is hingedly set between the upper and lower ear plates 13, both sides of the extension arm 2 62 and the extension arm 3 63 are provided with guide bars 66, and the inner walls of both sides of the extension arm 1 61 and the extension arm 2 62 are provided with guide grooves 67 that cooperate with the guide bars 66. The setting of the guide bars 66 and the guide grooves 67 ensures that the extension arm 2 62 and the extension arm 3 63 can be stably retracted or extended, and the structure is relatively simple. One end of the extension arm 1 61 and the extension arm 2 62 are threadedly connected with a fixing bolt 65, and the setting of the fixing bolt 65 facilitates the fixing of the extension arm 2 62 and the extension arm 3 63.

[0021] The water inlet end of the water supply pump 9 is connected to the water storage tank 3, and the water outlet end of the water supply pump 9 is connected to the main water pipe 11.
