[0002] Manual actuators are generally used for automatic control of valves. Their main function is to open, close or adjust valves through manual operation.

[0003] The existing manual actuator has a transmission mode of a screw nut external pull type, and the manual operation completely relies on manually rotating the wheel to mechanically transmit the screw thread, so as to push the sealing plug in the valve to open and close the valve.
