In some embodiments, the radial dimension of the first drive gear 44 is greater than the radial dimension of the second drive gear 45. It can be understood that, by setting the first transmission gear 44 to have a larger size, after the rotating force of the power member 43 is transmitted from the second transmission gear 45 to the first transmission gear 44, the rotating speed is reduced, so that the rotating speed of the connecting rod 2 is slower, the stability of the mopping module 210 is improved, and the reliability of the lifting process is improved.
