Technical Field

[0001] The utility model relates to the technical field of electric actuators, and particularly relates to an electric actuator with bidirectional execution. Background Technique

[0002] The broadest definition of an actuator is: a driving device that can provide linear or rotational motion, which utilizes a certain driving energy and operates under the action of a certain control signal; the actuator uses liquid, gas, electricity or other energy and converts it into a driving action through a motor, cylinder or other devices; for a bidirectional actuator, it usually needs to rely on the forward and reverse rotation of the execution motor to achieve.
