At this time, the limit cover 309 is loosened, and the limit cover 309 is pulled by the fixing spring 308 so that the limit pin 307 The reset insertion is carried out into the inner side of the slide groove 310 to fix the position of the slide plate 306. When the hose is removed, the limit pin 307 is pulled out to move the slide plate 306 to the lower end of the slide groove 310, so that the pressure plate 303 can be separated from the drainage hose and the drainage hose is released.
