The utility model discloses a buffer type shuttle valve structure which comprises a valve body, a valve element assembly, a first buffer piece and a second buffer piece. When the buffering type shuttle valve structure is used and high-pressure fluid is introduced into the port B compared with the port A, the buffering force of the first buffering piece is overcome to enable the valve element assembly to be located at the left position, and the port A of the valve body and the port T of the valve body are delayed to be communicated through the throttling hole; and when high-pressure fluid is introduced into the port A compared with the port B, the valve element assembly is located at the right position by overcoming the buffering force of the second buffering piece, and the port B of the valve body and the port T of the valve body are delayed to be communicated through the throttling hole. Therefore, according to the buffer type shuttle valve structure, due to the existence of the throttling holes, the corresp
