The utility model provides an overlaid flexible lifting device of a water mill, which belongs to the technical field of water mills and aims to solve the problems that the existing water mill is limited in swing angle amplitude and low in working efficiency when being used for polishing metal pipes with larger pipe diameters. A main body of the mounting base is of an inverted-U-shaped structure, a variable frequency motor is mounted in the middle of the upper end face of the mounting base, and the two sides of the upper end of the mounting base are each provided with a supporting plate. According to the grinding mechanism, the two ends of the swing arm are rotationally connected with the supporting plate, a worker can increase the air pressure in the air spring to prolong the length of the air spring, when the length of the air spring is prolonged, the swing arm can be driven to swing, and the grinding mechanism can be lifted in the swing process of the swing arm; and therefore, the cement blocks of the metal
