The utility model discloses an anti-seismic connecting device for an added elevator of an existing building, which comprises connecting support plates, an elevator car is connected between the two connecting support plates in a sliding manner, connecting plates are symmetrically arranged at two ends of the elevator car, a hydraulic cylinder is fixedly connected to the outer end of a cavity sliding plate, and a hydraulic rod is connected into an inner cavity of the hydraulic cylinder in a sliding manner. The resistance plug is rotationally connected with the hydraulic rod, and one end of the resistance plug is rotationally connected into an inner cavity of the cavity sliding plate. According to the anti-seismic connecting device for the added elevator of the existing building, the descending acceleration of the elevator car is monitored through the inductor, when the acceleration of the elevator car exceeds a threshold value, the inductor transmits a signal to the hydraulic cylinder, so that the hydraulic rod
