The following describes in detail the steps for using an anti-misturning mobile socket that integrates a single control and a total control in this article with reference to Figures 1 to 6:

In the initial state, the control plate 17 and the positioning plate 14 are in the upper limit position, the top pressure spring 27 and the return spring 47 are in a relaxed state, the energization plate 20 is in the upper limit position, and the opposite end of the clamping rod 16 extends into the control cavity 13, which is resistant to pressure. The spring 28 is in a relaxed state, the push block 34 is at the rear limit position, the synchronous push rod 41 is at the rear limit position, and the arc slider 46 is at the rear limit position and extends into the left front sector cavity 44 .

When the power is turned on, first press down the rightmost control button 51 and drive the control board 17 to descend. When the elastic force of the compression return spring 47 is too large, it drives the positioning plate 14 to descend. Retract into the clamping rod cavity 25, when the clamping slot 15 is opposite to the clamping rod 16, the clamping rod 16 is reset under the elastic force of the compression spring 28 and is stuck into the clamping groove 15, and then the positioning plate 14 is positioned Fixed, the positioning plate 14 drives the energizing plate 20 to drop to the conductive block 21 through the insulating rod 19, and then the circuit is connected, thereby realizing the opening of the main circuit switch.
