Zusammenfassung:	The utility model relates to a variable-cross section exhaust gas turbocharger actuating mechanism. Interference to a motor, by disturbance of waste gas flow disturbance to a nozzle ring, mechanical vibration and the like is eliminated by worm gear self-locking principle. The variable-cross section exhaust gas turbocharger actuating mechanism comprises the motor, a primary driving mechanism, a worm gear driving mechanism with a self-locking function, a connecting rod mechanism and the nozzle ring, wherein an output shaft of the motor is fixedly connected with a driving gear in the primary driving mechanism; a driven gear in the primary driving mechanism is fixedly connected with a worm rod in the worm gear driving mechanism; a worm gear in the worm gear driving mechanism is connected with a short rod in the connecting rod mechanism through a rotating shaft; a long rod in the connecting rod mechanism is connected with the nozzle ring. Unidirectional torque of the nozzle ring is transferred by the motor, a return spring part is eliminated, the cost is also reduced while the structure is simplified, the mechanical failure rate is reduced, and the motor can work with static current under a non-rotation working condition, so that the aim of saving energy is fulfilled, and the service life of the motor is prolonged.
