The two sides of the rotating plate 2 are provided with a slidable locking block 6 through a reset spring 5, the two sides of the base 1 are provided with a locking groove 1A cooperating with the locking block 6, one side of the locking block 6 is fixedly provided with a plug plate 7, the plug plate 7 is synchronously displaced with the sliding of the locking block 6, and the two sides of the base 1 are provided with a plug groove 1B cooperating with the plug plate 7. Through the reset spring 5, the locking block 6 and the plug plate 7 can reciprocate on the rotating plate 2, respectively cooperate with the locking groove 1A and the plug groove 1B, realize the effect of double locking, and make the rotating plate 2 be firmly fixed on the base 1. The double locking makes the rotating plate 2 more stable, and avoids affecting the stability of the entire connector when one of the locking block 6 or the plug plate 7 is worn or broken.

[0024] Moreover, the two sides of the locking block 6 are provided with a guide groove 6A, and the rotating plate 2 is provided with a guide block 2A corresponding to the guide groove 6A. Through the cooperation of the guide groove 6A and the guide block 2A, the locking block 6 can smoothly slide in the rotating plate 2, so that the sliding of the locking block 6 is more smooth, thereby ensuring the stability and reliability of the locking block 6 in the operation process. The locking block 6 and the plug plate 7 are respectively provided with a fixed groove 6B and a fixed block 7A cooperating with each other. The rotating plate 2 is provided with a limiting groove 2B cooperating with the fixed block 7A. The plug plate 7 is installed on the locking block 6 through the fixed block 7A.
