Through adopting above-mentioned scheme, first brush head reciprocating rotation of realization that can be fine, and this kind of mode is simple, and the operation is stable.
The utility model discloses a further setting is: the bottom of the two brush heads is respectively provided with a clamping groove, and the base is provided with a clamping strip which forms a running fit with the clamping grooves.
By adopting the scheme, the brush head and the base can be well fixed in the axial direction, and the brush head can be well ensured to rotate in the circumferential direction.
The utility model discloses a last setting is: the motor is characterized in that a transmission rod is arranged on the output shaft of the motor, the end part of the transmission rod is in a cross shape, one end, matched with the transmission rod, of the connecting rod is in a cross-shaped groove, and the connecting rod and the transmission rod are in linkage matching through matching of a cross structure.
By adopting the scheme, the transmission effect is good, and the operation is stable.
The present invention will be further described with reference to the following specific embodiments.
