In this embodiment, the electric control actuator 100 is provided with a driving device 110, a transmission device 120 and a driving device 110, the driving device 110 is connected with the transmission device 120 to drive the transmission device 120 to rotate, and the rotation device 120 is in transmission connection with the output device 130, so that the output device 130 can output rotation under the control of the electric control actuator 100.

Further, an elastic member 132 and a torsion spring limiter 133 are installed on the output device 130, the elastic member 132 is connected with the torsion spring limiter 133, and the torsion spring limiter 133 can rotate along with the output device 130. The torsion spring stopper 133 can fix the end of the elastic member 132, and the other end of the elastic member 132 is connected with the housing 140 of the electric control actuator 100. Thus, when the torsion spring limiting member 133 rotates along with the output device 130, a section of the elastic member 132 can rotate along with the torsion spring limiting member 133, so that the elastic member 132 deforms and stretches.

Further, when one end of the elastic member 132 is fixedly connected to one end of the torsion spring stopper 133, the compression and extension deformations of the elastic member 132 can be limited only by one torsion direction, which results in that the output shaft 131 of the electric control actuator 100 cannot freely rotate in two opposite directions. Therefore, in the manner of matching and connecting the elastic member 132 and the torsion spring limiter 133, a limiting groove 133d is added on the original basis, so that the torsion spring limiter 133 has a forward limiting groove 133a and a reverse limiting groove 133b, and the elastic member 132 can be respectively matched with the forward limiting groove 133a and the reverse limiting groove 133b.

The included angle between the forward limit groove 133a and the reverse limit groove 133b is set to 120 ° to facilitate the rotation and reversing of the electric control actuator 100, so that the output shaft 131 rotates 120 ° to enable the elastic member 132 to switch the limit groove 133d to cooperate, thereby realizing the forward and reverse rotation of the control valve of the electric control actuator 100. Further, the included angle is set to 120 ° to prevent the distance between the forward limit groove 133a and the reverse limit groove 133b from being set too close, which is inconvenient for the elastic member 132 to slide between the two limit grooves 133 d.
