For the arrangement of the rotating disk 12 and the connecting disk 21, before the transmission gear 13 is driven to rotate by the transmission gear slot 43, the connecting disk 21 is firstly used for driving the output rotating shaft 11 to rotate at a lower speed, so that the relative rotation speed difference between the transmission gear 13 and the transmission gear slot 43 is smaller, severe impact of the transmission gear slot 43 rotating at a high speed on the static transmission gear 13 is reduced, abnormal sound and blocking phenomenon generated in the transmission process of the clutch are effectively reduced, impact damage of the transmission gear 13 or the transmission gear slot 43 is reduced, and the service life of the clutch is prolonged.

In this technical scheme, the right side of the rotating disc 12 is provided with an outer convex curved surface structure with the same inclination angle as the inner concave curved surface 22, and the roughness between the surfaces of the rotating disc 12 and the inner concave curved surface 22 is all greater than Ra 50.
