In this way, by arranging the specific structure of the suction accessory 32, first, the movable connection between the suction accessory 32 and the extending member 314 is realized. Second, by tightening or loosening at least one of the first rotating member 322 and the second rotating member 323, the position of the suction accessory 32 in the strip-shaped hole 316 is adjusted, so that the position of the suction accessory 32 is adjustable. Third, by arranging the first rotating member 322 and the second rotating member 323, the position of the suction accessory 32 can be adjusted by rotating one of the first rotating member 322 and the second rotating member 323.
