[0029] A first groove is provided on one side of the connecting rod 9, and the inner surface of the first groove is matched with the outer surface of one side of the electric telescopic rod 10. The electric telescopic rod 10 is fixedly connected to the inside of the first groove. Before use, the electric telescopic rod 10 is extended to push out the two plug-in blocks 11 on the inner side of the connecting rod 9, so that the plug-in blocks 11 are inserted into the bottom of the separation cylinder 5, and the raw materials to be separated are added to the separation cylinder 5 in the centrifugal cylinder 2 through the feed pipe 4.

[0030] A first through hole is formed on one side of the connecting rod 9 , the inner surface of the first through hole is matched with the outer surface of the plug-in block 11 , and the plug-in block 11 is slidably connected to the inside of the first through hole.

[0031] A second groove is formed on one side of the separation cylinder 5, and the inner surface of the second groove matches the outer surface of one side of the connecting rod 9 and the plug-in block 11, and one side of the connecting rod 9 and the plug-in block 11 are both plugged into the second groove.
