The base is also provided with a first limit post, a second limit post, and a third limit post. The first microswitch is fixed between the first limit post and the second limit post, and the second microswitch is fixed between the second limit post and the third limit post. The second limit post is located on the mirror plane of the first microswitch and the second microswitch. A control circuit board is also arranged on the back of the first microswitch and the second microswitch, and the first microswitch and the second microswitch are respectively welded and fixed on the control circuit board.

[0029] Embodiment 2:

[0030] The first microswitch and the second microswitch are electrically connected to the control circuit board, and the control circuit board is fixedly installed on the back of the shell cover. A data transmission module is arranged on the control circuit board, and the data transmission module can perform signal transmission with a control terminal. For example, a mobile phone terminal is used to transmit a signal to the data transmission module, and the data transmission module then gives a signal for the control motor to rotate forward or backward. In addition, an indicator light for reflecting the state of the actuator is also arranged on the control circuit board, and the indicator light plays a prompting role through the shell cover.

[0031] The actual usage method is as follows:

[0032] The operation of the control motor is controlled by an external signal, which is usually provided by a terminal signal or a sensor, etc. The control motor drives the control block and the valve core to rotate. The control block is used to trigger the first microswitch and the second microswitch. The first microswitch and the second microswitch mainly function to give a stop rotation electrical signal, such as Figure 3 As shown, when the control block rotates counterclockwise and triggers the first microswitch, the control motor stops rotating counterclockwise. Conversely, when the control block rotates clockwise and triggers the second microswitch, the control motor stops rotating clockwise.

[0033] During assembly, the control circuit board is clamped and fixed between the fourth limit post and the first, second, and third limit posts. The first microswitch and the second microswitch are sleeved on the fifth limit post, and bolts are used to fixedly install the first microswitch and the second microswitch on the base through the second positioning holes.

Therefore, equivalent changes made according to the claims of the present invention still fall within the scope covered by the present invention.
