At the same time, since the lower positioning part 9 is positioned and cooperates with the air suction pipe 3, the lower positioning member 8 can drive the air suction pipe 3 to rotate as well when it rotates.

[0031] A cover plate 10 is provided on the cantilever 2, which covers the drive end of the drive motor 4, the transmission belt 5, the drive wheel, and the driven wheel.

[0032] In this embodiment, the cover plate 10 is used to cover the drive end of the drive motor 4, the transmission belt 5, the driving wheel, and the driven wheel to avoid the influence of foreign objects on the drive end of the drive motor 4, the transmission belt 5, the driving wheel, and the driven wheel, and to ensure the stability of the power transmission.
