The utility model discloses a protective device of an electric actuator, relates to the technical field of electric actuators, and solves the problems that the actual fixing effect is poor at present, a spring is limited in length, and when the height of the placed electric actuator is low, a pressing plate is difficult to effectively abut against the spring, so that the limiting effect is influenced, the electric actuator is difficult to stabilize, and the service life of the electric actuator is influenced. And the self protection effect is influenced. Comprising a fixed box, a box cover is hinged to the top of one side of the fixed box through two hinges, the middle of the box cover is in threaded connection with a threaded rod, the bottom end of the threaded rod is rotationally connected with a lower pressing plate, four first hollow grooves are formed in the lower pressing plate, and damping assemblies are arranged in the four first hollow grooves; according to the utility model, the top of the electric
