A worm gear 10 is sleeved and fixed on the outside of the connecting pipe two 6. Vertical plates 11 are fixedly provided on the outer bottom surface of the box body 1 on the front and rear sides of the worm gear 10. The rear end of the worm 13 is rotatably connected to the rear vertical plate 11, and the front end movably penetrates the front vertical plate 11. The vertical plate 11 is a rectangular plate and is vertically arranged. The worm 13 meshes with the worm gear 10.

[0022] An activity plate 14 is slidably arranged up and down in the box body 1. The activity plate 14 is a rectangular plate whose side surface slidably contacts the inner wall of the box body 1. A spring 15 is connected between the activity plate 14 and the top plate 22 of the box body 1. An air outlet hole 16 is provided on the top plate 22 of the box body 1; a handle 23 is provided on the outer side wall of the right part of the box body.

[0024] When the spring 15 between the activity plate 14 and the top plate of the box body 1 is in a natural state, the activity plate 14 is higher than the water injection hole 17.

[0025] The length of the spraying pipe 8 is less than the distance between the two support rods 3 on the front side of the box body 1 and greater than the distance between the front and rear side plates of the box body 1; the lower ends of the two vertical plates 11 are both higher than the top surface of the spraying pipe 8.
