In the process of the electric telescopic rod pushing the baffle 7 to drive the second brush body 2012 away from the first brush body 2011, the sliding rod 602 synchronously moves outward along the sliding groove 6011. At this time, the elastic member 603 is pulled, and when the electric telescopic rod is closed, the elastic member 603 drives the sliding rod 602 to move in the opposite direction by its elastic action, thereby driving the second brush body 2012 to move in a direction approaching the first brush body 2011, and comes into close contact with the blade, completing the blade brushing operation.

Specifically, in this embodiment, the elastic member 603 is a spring.

Of course, in an alternative embodiment, the fixed block 601 may be connected to the second brush body 2012 and the sliding rod 602 may be connected to the first brush body 2011, thereby achieving movement of the second brush body 2012 toward the first brush body 2011.
