After the support plate 23 is swung to a suitable position, the second fastener 25 is passed through the waist-shaped hole 232 and connected to the sweeping disc assembly 10, so that the second fastener 25 cooperates with the first fastener 24 to fix the support plate 23 on the sweeping disc assembly 10, preventing the support plate 23 from driving the spray rod 22 to swing during the cleaning operation, and the structure is stable and reliable; and, in the case of changes in the cleaning operation requirements, the second fastener 25 can be loosened to swing the support plate 23 to adjust the angle of the spray rod 22, thereby adjusting the operating width of the flushing water curtain sprayed by the spray rod 22, and the adjustment is flexible and convenient.

[0041] In the embodiment of the utility model, the support plate 23 includes a support section 233 and an inclined section 234. One end of the support section 233 is adjustably disposed above the disk body 11. The inclined section 234 extends from the other end of the support section 233 from top to bottom and is inclined forward relative to the axis of the sweeping disk assembly 10.
