When installing the mounting gear 3, first install the mounting gear 3 on the outside of the plug-in fixing frame 2, and then limit the mounting gear 3 by the fastening sleeve 4, and then fasten the fastening sleeve 4 by the threaded fastening sleeve 5.

[0023] The right end of the mounting gear 3 is fixedly connected with three plug-in rods 7 in a circular array, and the plug-in rods 7 are correspondingly plugged into the plug-in holes 11. The plug-in holes 11 are provided on the right end surface of the plug-in fixing frame 2. The right end of the plug-in fixing frame 2 is provided with three plug-in holes 11 in a circular array, and the inner side of the mounting gear 3 is provided with three clamping grooves 8 in a circular array.
