The invention relates to a multi-stage swing system for quickly connecting a prefabricated assembled pier and a bearing platform. The system mainly comprises a bottom sealing plate, an upper disc, prestressed tendons, a U-shaped energy dissipater, a lower disc and limiting angle steel. The bottom sealing plate is anchored at the bottom of the pier column; the upper disc comprises a top plate, a groove and a support plate; the lower disc comprises a ball pin, a ball pin step and a bottom plate; the groove and the ball pin are nested with each other to limit the transverse displacement of the upper disc, a first support plate is supported on the ball pin step, and the ball pin and the ball pin step bear a vertical load together; a second support plate is connected with the bottom plate through limiting angle steel to limit relative rotation of the upper disc and the lower disc; the U-shaped energy dissipater is arranged between the top plate and the bottom plate, and a steel base plate is arranged between the b
