The utility model relates to the technical field of electric actuators, in particular to a multi-turn rotation support-free field adjustable electric actuator which comprises a shell, an indicator is arranged above the shell, an output port is arranged at the bottom of the shell, a fixing shaft is fixedly connected between the output port and the indicator, and the fixing shaft is rotatably connected with the shell. A fixed shaft is arranged in the shell, a driving motor for driving the fixed shaft to rotate is arranged in the shell, the upper part of the fixed shaft is fixedly connected with a limiter, the upper part of the shell is fixedly connected with a micro switch, the micro switch is electrically connected with the driving motor, the micro switch is arranged below the limiter, and a pressing plate in contact with the micro switch is arranged on the limiter. When the electric actuator is used abnormally, the limiting stopper on the fixing shaft rotates to the microswitch, the microswitch is pressed thr
