The invention provides an elevator anti-falling device used for lifting and triggering elevator safety tongs to act. The device comprises a rotary lifting plate, an extension spring and a heavy block,one end of the rotary lifting plate is rotationally connected with a car frame, and the other end of the rotary lifting plate is fixedly connected with the car frame through the extension spring; theheavy block is hung in the middle of the rotary lifting plate slightly deviating from a connecting end of the extension spring, and a position, away from the extension spring, of the middle of the rotary lifting plate is connected with a safety tongs lifting mechanism. The invention further discloses an elevator safety protection device. The elevator anti-falling device is reasonable and ingenious in structural design, high in safety performance and low in cost, when an elevator has a falling risk, the weightlessness state can be instantly sensed, the safety tongs are triggered to act, and normal operation of an existing safety component is not affected.
