Novel centrifugal clutch

The utility model discloses a novel centrifugal clutch which comprises a drum wheel, a barrel is arranged on the inner wall of a through hole of the drum wheel, a rotating shaft is arranged in an inner cavity of the barrel, fixing plates are fixedly connected to the two sides of the outer wall of the barrel, tension springs are fixedly connected to the two sides of the two fixing plates, brake blocks are fixedly connected to the tops of the tension springs in a pairwise mode, and the brake blocks are arranged on the inner wall of the drum wheel. Clamping mechanisms are arranged on the front faces of the two brake blocks correspondingly, and sliding mechanisms are arranged on the two sides of the two fixing plates correspondingly. According to the novel centrifugal clutch, the supporting plate, the clamping block and the clamping groove are matched with one another, the drum wheel can rotate along with the rotating shaft, when the centrifugal force is reduced due to the fact that the rotating speed is reduced,
