When the rotating wheel 6 does not rotate, the friction plates and the rotating wheel are also in contact and pressed to generate a certain friction force, when the rotating wheel 6 rotates (clockwise in the figure), the centrifugal block 14 moves to the radial direction of the rotating wheel under the action of centrifugal force to drive the long connecting rod 12 to rotate anticlockwise, the short connecting rod 13 rotates anticlockwise, and the friction plates 15 are pressed to be in close contact with the outer edge of the fixed wheel 5 or the friction plates 15 on the fixed wheel, so that the friction force is generated.
