The existing centrifugal flail type speed governor mainly comprises a support, a rope wheel, a ratchet wheel, a pawl, a pressure pawl, two flail components, a flail connecting rod, an adjusting screw, a rope pressing and beating assembly and a limit switch. The centrifugal flail type speed governor is operated by using the principle that the centrifugal force increases with the change of rotating speed. When the rope wheel of the speed governor rotates, the two flails in the speed governor tend to move away from the rotation center due to the centrifugal force. Once the speed exceeds the limit, the flails trigger the overspeed limit switch, and then the pressure pawl, the pawl, the ratchet wheel and the rope pressing and beating assembly generate a safety clamp action, so that the rope pressing plate in the rope pressing and beating assembly and the rope wheel clamp the steel wire rope, to avoid the phenomenon of rapid operation of the elevator due to failure, thereby ensuring safety. The centrifugal flail is generally produced by using a special mold.
