Normally, the elastic member connects the stopper 6 with the brake disk 5 through the elastic member mounting hole 52. The elastic member mounting portion 62 of the stopper 6 has an opening circle from which the elastic member can be disengaged. When the brake disc 5 receives a centripetal force greater than the tensile force of the elastic member, the elastic member comes off the elastic member mounting portion 62 of the brake dog 6. Because one end of the braking block 6 is fixed to one end of the braking wheel disc 5, the braking block 6 moves around the position of the fixing hole 61, and the stopping groove 63 is engaged with the stopping member 11, so that the gear set 2 stops rotating, and the airing assembly is stopped from moving. The stop groove 63 is close to the elastic piece mounting part 62, and the sum of the thicknesses of the elastic piece and the stop groove 63 is not more than the thickness of the brake block 6, so that the brake block 6 can rotate along with the brake wheel disc 5 under the normal working condition of the clothes drying machine, and the movement of the brake block 6 is not hindered.
