The invention provides a self-locking type electric servo mechanism and a centroid adjusting machine, the self-locking type electric servo mechanism comprises a driving motor, a flexible coupling, a fixed support, a trapezoidal screw rod, a conveying nut and a supporting support, the driving motor is connected with the trapezoidal screw rod through the flexible coupling, the conveying nut is matched with the trapezoidal screw rod to form a screw rod pair, and the supporting support is connected with the trapezoidal screw rod. The fixing support is located on the front section of the trapezoidal lead screw, the supporting support is located on the rear section of the trapezoidal lead screw, the trapezoidal lead screw is fixed, fork lugs are symmetrically arranged on the two sides of the conveying nut, the symmetry plane of the upper plane and the lower plane of each fork lug is coplanar with the axis of the trapezoidal lead screw, and each fork lug is provided with a vertical groove. And a pair of arc structures symmetrical relative to the vertical surface of the groove is arranged in the groove. According to the invention, overload resistance is realized from a mechanical structure, the motor power is saved, and the motor capacity design is optimized.
