2. The applying mechanism of claim 1, wherein: the connecting end is provided with a holding mechanism which is used for pushing the brush piece to rotate at the outer side of the shaft sleeve.
3. The application mechanism according to claim 1 or 2, characterized in that: the smearing mechanism further comprises a rotating ring, an annular boss is arranged on the outer side wall of the shaft sleeve, the rotating ring is sleeved on the periphery of the shaft sleeve, the rotating ring can rotate on the shaft sleeve, the lower end face of the rotating ring is abutted to the annular boss, and the rotating ring is connected with the brush piece.
4. A painting mechanism according to any one of claims 3, characterised in that: the shaft sleeve is sleeved with a limiting ring, the limiting ring is in limiting fixation with the shaft sleeve, and the lower end face of the limiting ring is connected with the upper end face of the rotating ring.
5. An application device comprising an application mechanism as claimed in any one of claims 1-4, further comprising a power mechanism, wherein the power mechanism is provided with a rotating shaft, and wherein the sleeve is sleeved outside the rotating shaft.
6. A painting method for working with the painting mechanism according to any one of claims 1 to 4, characterized in that the painting method comprises the steps of:
sleeving the bushing plate and the shaft sleeve on the rotating shaft;
pouring a smearing material on the upper end surface of the bushing;
the brush piece is driven to rotate outside the shaft sleeve, so that the smearing end is connected with the bushing, and smearing materials are extruded into the through hole through the smearing end;
and (3) extracting the bushing and the shaft sleeve from the rotating shaft to finish smearing operation.
