When the water collecting box 10 needs to be taken down, the second fixing member 80 is only required to be stretched downwards, so that the locking button 800 is clamped in the first through hole 703. When the height of the water collecting box 10 needs to be raised to a working height, the locking button 800 is only required to be pressed down, and the second fixing member 80 is pushed to be accommodated in the groove 702.

Referring to fig. 7, in one embodiment, the first fixing rod 310 includes a third fixing member 90. The surface of the second fixing member 80 away from the first fixing member 70 is provided with a second groove. And a second through hole is formed in the side wall of the second groove. The second fixing member 80 is configured to slide along the second groove. The third fixing member 90 is provided with a second locking button 801 corresponding to the second through hole.

The third fixing member 90 can be received in the second groove, reducing the overall length of the first fixing rod 310. When the water collecting box 10 needs to be removed, the second fixing member 80 and the third fixing member 90 are only required to be pulled downwards, so that the locking button 800 is clamped in the first through hole 703. The second locking button 801 is clamped in the second through hole. When the height of the water collecting box 10 needs to be raised to a working height, the locking button 800 is simply pressed to push the second fixing member 80 to be received in the groove 702, and the second locking button 801 is pressed to push the third fixing member 90 to be received in the second groove.

In one embodiment, the first fixing lever 310, the second fixing lever 320, the fourth fixing lever 410 and the fifth fixing lever 420 are all of a telescopic structure to facilitate the access of the water collecting box 10.
