[0025] like Figures 5 to 7 As shown, a second positioning chuck is formed on the inner side of the module panel 102, and N positioning grooves 1022 are arranged circumferentially along the second positioning chuck, and each positioning groove 1022 is correspondingly provided with a position code to indicate key position information;

[0026] The shape of the anti-mistaken plug 104 is consistent with the second positioning chuck of the module panel 102, and N key setting parts are distributed in the circumferential direction corresponding to the N positioning grooves 1022, and N-1 key setting parts are provided with positioning blocks adapted to the positioning grooves 1022, and the remaining key setting part is provided with a plug 1041, and the plug 1041 can be inserted into the key hole formed by the anti-mistaken socket 103 and the base panel 101;
