The three first abutting plates 22 are hingedly connected to each other, that is, two of the first abutting plates 22 are respectively hingedly connected to the two side surfaces of the other first abutting plate 22, and the first abutting plate 22 in the middle is fixedly connected to the support rod 21. The three second abutting plates 23 are hingedly connected to each other, that is, two of the second abutting plates 23 are respectively hingedly connected to the two side surfaces of the other second abutting plate 23, and the three second abutting plates 23 are simultaneously movably connected to the support rod 21. The driving member 24 is used for simultaneously driving the movement of the first and second connecting plates. When the actuator body 1 is installed, the three first abutting plates 22 and the three second abutting plates 23 simultaneously abut on the circumferential side surface of the pipeline.

[0031] With reference to Figures 1-4 ​In the installation process of the actuator body 1, the first abutting plates 22 are abutted on the axial sidewall of the pipeline at the same time, which increases the contact area between the electric actuator and the pipeline, improves the stability of the actuator body 1 on the pipeline during installation, reduces the possibility of falling of the actuator body 1, and facilitates the installation of the electric actuator. Moreover, the second abutting plates 23 are arranged, which further increases the contact area between the electric actuator and the pipeline, improves the stability of the actuator body 1 on the pipeline during installation, reduces the possibility of falling of the actuator body 1; the actuator body 1 can be positioned during installation, and the installation position of the actuator body 1 can be positioned, which facilitates the subsequent plug-in installation of the actuator body 1 and the shaft of the valve, thereby facilitating the installation of the electric actuator.
