The pulling rod 041 may include a rod structure 0411 and a pulling portion 0412 connected to one end of the rod structure 0411. The pulling rod 041 may be engaged with the corresponding sliding groove 03a through the second connector 042, and the pulling rod 041 may slide along the extending direction of the sliding groove 03 a. The tension rod 041 may be configured to be movable in the extending direction of the rod-like structure 0411.

Fig. 3 is an effect view of the dismounting device shown in fig. 1 when the electric actuator is dismounted. Referring to fig. 3, when the electric actuator 20 fails and needs to be detached from the rotating shaft 10 of the valve for maintenance or replacement, the detaching device 00 may be disposed on a side of the electric actuator 20 away from the rotating shaft 10 of the valve, and the one end of the push rod 01 may abut against the rotating shaft 10 of the valve, and after the electric actuator 20 is clamped with the pulling portion 0412 at one end of the pull rod 041, the operator may rotate the push rod 01 to rotate the push rod 01 around its own axis. When the push rod 01 rotates around the axis thereof, the first connecting piece 02 screwed with the push rod 01 can move in the direction away from the rotating shaft 10 of the valve. At this time, the supporting arms 03 fixedly connected to the first connecting member 02 can move in a direction away from the rotating shaft 10 of the valve, so that the hook members 04 corresponding to the supporting arms 03 one to one can drive the electric actuator 20 to move in a direction away from the rotating shaft 10 of the valve, and the electric actuator 20 can be detached from the rotating shaft 10 of the valve.

Moreover, since the support arm 03 is provided with the sliding groove 03a, the pull rod 041 can be clamped with the sliding groove 03a through the second connecting piece 042, and the pull rod 041 can slide along the extending direction of the sliding groove 03a, the distance between each pull rod 041 of the plurality of hook members 04 and the ejector rod 01 in the dismounting device 00 can be adjusted by adjusting the position of the pull rod 041 in the extending direction of the sliding groove 03a, so that the dismounting device 00 can be used for dismounting a plurality of electric actuators 20 with different lengths or widths, and the flexibility is good. Meanwhile, when the position of the pull rod 041 in the axial lead direction of the pull rod 041 needs to be adjusted, the second connector 042 and the corresponding sliding groove 03a may be released from the clamping relationship (the second connector 042 is not in contact with the corresponding sliding groove 03a), then the position of the pull rod 041 in the axial lead direction of the pull rod 041 may be adjusted, and finally the second connector 042 is in contact with the sliding groove 03a, so that the pull rod 041 may be clamped with the sliding groove 03a via the second connector 042.

Alternatively, for each support arm 03, the extending direction of the sliding groove 03a in the support arm 03 may be parallel to the extending direction of the support arm 03. That is, the pull rod 041 is slidable in the extending direction X of the support arm 03. Of course, an included angle may exist between the extending direction of the sliding groove 03a in the support arm 03 and the extending direction of the support arm 03, and the included angle may be smaller than or equal to the included angle threshold. For example, the angle threshold may be 20 degrees.

Referring to fig. 6, the rod-shaped structure 0411 and the pulling part 0412 may be a unitary structure, for example, the rod-shaped structure 0411 and the pulling part 0412 may be integrally formed. Alternatively, the rod-shaped structure 0411 may be connected with the pulling part 0412 by welding, or alternatively, the rod-shaped structure 0411 and the pulling part 0412 may be connected by screws. The connection manner of the rod-shaped structure 0411 and the pulling portion 0412 is not limited in the embodiments of the present application.

By way of example, fig. 2 shows two support arms 03, and the two support arms 03 are uniformly distributed along the circumference of the first connector 02, i.e. the extension directions of the two support arms 03 are collinear. That is, the angle between the two support arms 03 may be 180 degrees.

As can be seen by referring to fig. 3 to 6, the size of one end of the stem lifter 01 for abutting against the rotating shaft 10 of the valve may be smaller than the size of the other end of the stem lifter 01. Therefore, one end of the ejector rod 01 can be inserted into the opening of the rotating shaft 10 of the valve, the ejector rod 01 cannot move relative to the rotating shaft 10 of the valve when the ejector rod 01 rotates around the axis of the ejector rod 01, and the first connecting piece 02 can be driven to move towards the direction far away from the rotating shaft 10 of the valve when the ejector rod 01 rotates.

When one end of the push rod 01 abuts against the rotating shaft 10 of the valve, one end of the conical structure, which is far away from the supporting arm 03, can be located in the opening of the rotating shaft 10 of the valve. Alternatively, referring to fig. 6, one end of the stem 01 for abutting against the rotating shaft 10 of the valve may be provided with an opening, so that a pin may be inserted into the opening of one end of the stem 01 and may protrude from one end of the stem 01. When one end of the push rod 01 is abutted with the rotating shaft 10 of the valve, the part of the pin protruding out of the push rod 01 can be inserted into the opening of the rotating shaft 10 of the valve.
