When the power component 7 is energized, a magnetic attraction force is generated between the power component 7 and the mounting plate 12, and the power component 7 is fixedly connected to the housing 2.

[0029] The power member 7 is a magnet, which is used to ensure that a magnetic attraction force is generated between the power member 7 and the mounting plate 12 after the power member 7 is energized.

The degree signal is transmitted to the external control system, and the cleaning member 10 slides along the guide member 9 under the action of gravity until it contacts the limit plate 91; during this process, the external control system intermittently powers on and off the power member 7 through the connecting wire 5. When the power member 7 is energized, a magnetic attraction is generated between the power member 7 and the mounting plate 12 of the cleaning member 10, so that the mounting plate 12 moves toward the power member 7 until it contacts the limit surface 6. When the power member 7 is de-energized, the mounting plate 12 contacts the limit plate 91 again under the action of gravity.
