Anti-seismic prefabricated segment assembly pier connecting device

An upper prefabricated pier and a lower prefabricated pier are fixedly connected through a connecting seat, a connecting sleeve is fixedly connected to the outer wall of the connecting seat, a connecting ring is arranged above the connecting seat, and the upper prefabricated pier and the lower prefabricated pier are sleeved with the connecting ring and the connecting sleeve respectively. A plurality of first rotating seats are fixedly connected to the outer walls of the connecting sleeve and the connecting ring, and the same elastic plate is rotationally connected between every two vertically-corresponding first rotating seats and used for further fixing the upper prefabricated pier and the lower prefabricated pier, so that the upper prefabricated pier and the lower prefabricated pier can automatically reset when inclining; the buffering mechanism is arranged on the connecting base and used for buffering the prefabricated pier on the upper portion, and the anti-seismic effect of the connecting position is imp
