[0025] Secondly, the "one embodiment" or "embodiment" referred to herein means that the specific features, structures or characteristics can be included in at least one implementation manner of the utility model. "In one embodiment" appearing in different places in the specification does not mean the same embodiment, nor is it an embodiment that is independent of or mutually exclusive with other embodiments. The utility model provides the following embodiments.

[0026] As shown in Figure 1 and Figure 2 , it is a structural schematic view of the electric actuator transmission extension device in the embodiment, the device comprises a conducting piece 4, the conducting piece 4 is installed below the electric actuator, the electric actuator is composed of an actuator body 1, a side shell 2 and a bottom disc 3, the side shell 2 is symmetrically installed below the actuator body 1 and on both sides of the conducting piece 4, the bottom disc 3 is installed on the side shell 2, a plug-in slot is formed in the middle end of the bottom disc 3, the conducting piece 4 penetrates the plug-in slot, a plurality of groups of connecting grooves are equidistantly formed on the bottom disc 3, a threaded rod is installed inside the connecting groove, the threaded rod penetrates the connecting groove, and an adjusting mechanism 5 is installed in the side shell 2.

[0027] When used, the bottom disc 3 is attached to the top end of the valve with control, then the threaded rod is turned into the connecting groove inside, the electric actuator is quickly installed on the valve by cooperating with the use of the connecting flange on the valve, at this time the conducting piece 4 is connected with the control end of the valve, with the use and operation of the actuator body 1, the conducting piece 4 drives the control end to rotate synchronously, so as to control the opening and closing and start and stop of the valve itself.

[0028] As shown in Figure 3 and Figure 4As shown, this is a schematic diagram of the structure of the adjustment mechanism 5 in this embodiment. The adjustment mechanism 5 includes a lead screw 51, a movable frame 52, and a rotating end 53. A movable groove is provided inside the side housing 2. The lead screw 51 is rotatably installed inside the movable groove. The movable frame 52 is threaded onto the outside of the lead screw 51 and is connected to the chassis 3. A rotating end 53 is installed at the end of the side housing 2 and is connected to the end of the lead screw 51. A guide rod 54 is fixedly installed inside the movable groove. The guide rod 54 is parallel to the position of the lead screw 51 and is slidably connected to the movable frame 52.

[0029] When the overall length of the transmission component 4 needs to be adjusted, the rotating end 53 is rotated. At this time, the rotating end 53 drives the lead screw 51 to rotate in the moving groove, and the moving frame 52 moves along the external thread direction of the lead screw 51. The rotating end 53 drives the overall height of the chassis 3 to rise and fall, controlling the distance between the chassis 3 and the end of the actuator body 1. Utilizing the structure of the transmission component 4 itself, the length of the transmission component 4 extends and retracts along with the movement of the chassis 3, thereby achieving the purpose of adjusting the transmission distance.

[0030] From the appendix Figure 5 and Figure 6 As shown, this is a schematic diagram of the structure of the transmission component 4 in this embodiment. The transmission component 4 includes a telescopic rod 41 and a telescopic cylinder 42. The telescopic cylinder 42 is installed at the bottom of the actuator body 1, and the telescopic rod 41 is installed below the telescopic cylinder 42. The bottom of the telescopic rod 41 is equipped with a connecting end that connects to the valve control end. The upper surface of the chassis 3 is symmetrically equipped with mating seats 44. The bearing body 43 is rotatably installed in the mating seat 44. The bearing body 43 is connected to the telescopic rod 41. The bearing body 43 is a ball bearing. The mating seat 44 has a rotating groove to assist the bearing body 43 in rotating.

[0031] When the chassis 3 moves, the telescopic rod 41 slides stably inside the telescopic cylinder 42. Rectangular limit blocks are installed on both sides of the telescopic rod 41, and the telescopic cylinder 42 has a lifting groove that cooperates with the limit blocks for vertical sliding. This ensures that while the telescopic rod 41 slides stably in the telescopic cylinder 42, the telescopic cylinder 42 can also rotate stably when the telescopic rod 41 rotates. This facilitates the synchronous rotation of the telescopic cylinder 42, the connecting end, and the control end. Furthermore, by using the bearing body 43 and the mating seat 44, when the chassis 3 moves, the mating seat 44 drives the bearing body 43 to move, thereby achieving the purpose of controlling the overall length of the transmission component 4.
