Moreover, when the roller brush 30 is installed, as long as the turbine head 21 is partially engaged with the first transmission member 31, the first transmission member 31 is more tightly engaged with the turbine head 21 with the rotation of the turbine head 21, so that the driving assembly 20 is forced to move toward the roller brush 30 until the predetermined position is reached, and therefore, the first transmission member 31 can be automatically matched to the optimal position under the driving of the turbine head 21.

When the first transmission member 31 is just engaged with the turbine head 21, the turbine head 21 can rotate relative to the first transmission member 31, that is, the turbine head 21 and the first transmission member 31 cannot rotate synchronously, the engagement between the turbine head 21 and the first transmission member 31 becomes tighter and tighter along with the change of the relative position between the turbine head 21 and the first transmission member 31, and finally, after the first transmission member 31 moves to the predetermined position, the turbine head 21 drives the first transmission member 31 to rotate synchronously.
