Centrifugal clutch based on improved centrifugal block structure

The centrifugal clutch based on the improved centrifugal block structure comprises an input shaft, four sets of fixing blocks opposite in position are fixedly installed at the top end of the surface of the input shaft, the middle of the side face of each fixing block is fixedly connected with one end of a spring, and the other end of each spring is fixedly connected with a fan-shaped centrifugal block. A through sliding groove is formed in the top face of the fan-shaped centrifugal block, a driving disc is assembled at the top end of the input shaft, four sets of fan-shaped grooves opposite in position are formed in the inner side wall of the driving disc, a first friction plate is fixedly installed on the top face of the driving disc, a shifting block is arranged above the driving disc, and a second friction plate is fixedly installed on the bottom face of the shifting block. And an output shaft and a shifting block are fixedly installed in the middle of the top face of the shifting block, the output shaft i
