Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

It should be noted that the technical solutions in the embodiments may be combined with each other, but it must be based on the realization of those skilled in the art, and when the technical solutions are contradictory or cannot be realized, the combination of the technical solutions should not be considered to exist, and is not within the protection scope of the present invention.

Referring to fig. 1 and 2, an embodiment of the charging stand of the present invention includes a roller brush shaft 4 and a sheath 3. The horizontal both ends of round brush axle 4 are first end 1 and second end 2 respectively, first end 1 is used for pin joint cleaning device actuating mechanism, possesses the interior polygon interface of approximate rectangle, changes and drives the structural assembly, prevents the phenomenon of skidding of idle running, the utility model discloses do not restrict the shape of first end 1. The second end 2 is provided with an end cover 21 made of soft material, and the end cover 21 is rotatably connected with the rolling brush shaft 4. Preferably, the end cap 21 is made of TPU material by integral molding.

The sheath 3 is sleeved on the rolling brush shaft 4, a plurality of rows of brushes 31 are arranged on the sheath 3, and the positions of the brushes 31 gradually change towards the circumferential direction of the rolling brush shaft 4 along the two ends of the rolling brush shaft 4 towards the central direction of the rolling brush shaft 4.
