description The utility model relates to the field of variable frequency motors. The utility model relates to a fixing structure, in particular to an anti-loosening fixing structure of a flywheel and a cooling fan of a variable-frequency motor. The flywheel assembly comprises flywheels and shaft sleeves, the shaft sleeve is arranged in the center of the flywheel; a plurality of mounting holes are uniformly distributed in the flange part of the shaft sleeve; rivet holes are formed in positions, corresponding to the mounting holes, of the axial end surface of the flywheel; an internal thread pin for mounting a cooling fan penetrates through the mounting hole and the rivet hole; the flange is fixed on the flange part through riveting; the internal thread pin is a stepped cylinder; one end of the steppedcylinder is a large-diameter section; small-diameter section is arranged at the other end of the body, a medium-diameter section is arranged between the large-diameter section and the small-diameter section; a tangent plane f
