description The utility model provides a coaxial driver with one-direction bearing clutch. The utility model has the structure that a one-direction bearing clutch is arranged on a transmission shaft and connected with a gear. One end of the transmission shaft is opened with a groove for inserting a hand operating handle, and the other end of the transmission shaft is connected with a cam. The cam with a roller is engaged with a long slot of the slide block. The utility model has the advantages of being an essential component in an electric operating mechanism transmission device of the plastic shell type breaker, adopting the method that electric operation and hand operation conduct transmission on the same axle in order to make the structure compact and the performance reliable. When in hand operation, the transmission shaft is directly operated to bring the cam and the slide block with the aim to open, close, break off and refasten the breaker. At the moment, the clutch is in a status of separating from a decelerating mechanism, thus the operating force is small. When in electric operation, the clutch is in the status of close, and an electric motor is decelerated to drive the transmission shaft to rotate and conduct the electric operation.
