This invention proposes a manual interface for electric actuators, mainly comprising a manual bevel gear, a translational bevel gear, and a flexible shaft. This manual interface solves the problem of flexible arrangement of manual interfaces for electric actuators, allowing users to operate manually from a distance. In manual mode, the electric drive chain is disconnected; in electric mode, the manual drive chain is disconnected. When the electric component is functioning normally, the manual component does not rotate. This facilitates flexible arrangement, improves reliability, and extends service life. Even if the motor burns out or jams in manual mode, the manual function remains unaffected. In manual mode, the front-stage reduction gear is disconnected, eliminating the need for gear-driven speed increase to pull the motor during manual rotation, resulting in lower manual torque and easier operation. Since the manual power source speed is much lower than the motor speed, the manual bevel gear is positioned before the bidirectional backstop mechanism and after the front-stage reduction gear, achieving a suitable manual transmission ratio. This allows for better coordination between manual and electric speeds, and the manual operation features full reverse self-locking for safety and reliability.
