Specifically, the motor 21 is disposed on a fixed disk 23, and a through hole for the output shaft 22 to pass through is formed in the fixed disk 23.

The brush tray 1 includes a tray body 11 and brushes 12 provided on the tray body 11. The mounting structure connects the output shaft 22 with the disk 11.

When the brush disc 1 is connected with the driving mechanism 2, the clamping head 3 is inserted into the accommodating cavity of the chuck 4, so that the first protrusions 31 are inserted between the adjacent second protrusions 41, meanwhile, the elastic clamping buckles 32 are inserted into the grooves 40, and the first protrusions 31 are matched with the second protrusions 41 to limit the circumferential direction of the brush disc 1, so that the brush disc 1 cannot rotate relative to the driving mechanism 2 but rotates under the driving of the driving mechanism 2; the elastic buckle 32 is inserted into the groove 40 to limit the axial direction of the brush disc 1, so that the brush disc 1 is prevented from being separated from the driving mechanism 2; because the recess 40 is the annular, all elasticity buckles 32 all insert simultaneously in the recess 40, can realize the blind dress between brush dish 1 and the actuating mechanism 2, only need to push hard promptly can realize the installation, improved the installation effectiveness. When the brush disc 1 is disassembled, external force is applied to the brush disc 1, so that the elastic buckle 32 is separated from the groove 40, the brush disc 1 is separated from the driving mechanism 2, and the brush disc 1 is convenient to replace.

When the outer surface of the first protrusion 31 and the outer surface of the second protrusion 41 are both arc surfaces, when the first protrusion 31 is likely to abut against the second protrusion 41, when two first protrusions 31 abut against two second protrusions 41 at the same time, the first protrusion 31 is stuck, so that the first protrusion 31 cannot be inserted between the adjacent second protrusions 41, and the first protrusion is required to be pulled out and rotated for re-insertion at a certain angle, thereby affecting the installation efficiency.

In this embodiment, the outer surface of the first protrusion 31 is in the shape of a ridge having a first ridge line 311, both sides of the first ridge line 311 form slopes, the outer surface of the second protrusion 41 is in the shape of a ridge having a second ridge line 411, and both sides of the second ridge line 411 form slopes. The arrangement of the first ridgeline 311 and the second ridgeline 411 can reduce the contact area between the first protrusion 31 and the second protrusion 41 during installation, thereby reducing the probability of seizure. But there is still a possibility: when the first ridgelines 311 of the two first protrusions 31 abut against the second ridgelines 411 of the two second protrusions 41, the first ridges are pushed up, and the first ridges need to be pulled out and rotated by a certain angle to be inserted again, which affects the installation efficiency.
