The invention relates to an actuating mechanism of an air suction valve of an auxiliary power device air suction system. The actuating mechanism of the air suction valve is used for opening and closing the air suction valve of the auxiliary power device air suction system on the ground and in the air. The actuating mechanism is convenient to install and disassemble and good in accessibility and maintainability; the occupied installation space is small, and the weight is light; a torque amplification function is realized, and an output torque can be adjusted. The actuating mechanism of the air suction valve of the auxiliary power device is installed on a position at the downstream side adjacent to the air flowing direction of the outer side of an air suction chamber, the actuating mechanism consists of an electric actuator and a torque adjusting mechanism, the electric actuator is a rotating electric actuator, one end of the torque adjusting mechanism is connected to an output shaft of the electric actuator, the other end of the torque adjusting mechanism is connected to the air suction valve, and the torque adjusting mechanism can amplify the torque outputted by the electric actuator and can adjust the outputted torque.
