The lever centrifugal automatic clutch includes a driving disc, at least two sets of centrifugal mechanisms and a driven disc, a power sleeve is arranged in the center of the driving disc, a driven disc buckle is set on the edge of the centrifugal mechanism, and a power output mechanism is arranged on the driven disc. The adjacent two groups of centrifugal mechanisms are connected end to end and evenly distributed on the drive plate. The centrifugal mechanism is composed of a centrifugal body, a special-shaped lever, a tension spring, a centrifugal body positioning post and a special-shaped lever positioning post. This invention effectively reduces the The energy loss of the clutch during operation, especially in the low-speed working state, the output torque (power) is relatively large. At the same time, under the condition of ensuring the function, its structure is simplified.
