The tapered core 222 is sleeved on the cylindrical portion 214, and the sleeved hole 2232 is sleeved on the non-cylindrical portion 215. Thus, the rotating shaft 21 can carry the grinding core 22 to perform stable rotating motion, so that the conical core 222 can be driven to perform stable rotating motion, the grinding stability can be ensured, the vertical movement of the grinding core 22 can be ensured to be smoother, and the processing of the grinding core 22 and the rotating shaft 21 can be facilitated.

As shown in fig. 2 to 5, the grinding ring 3 is vertically arranged, the lower hole Duan Cheng of the grinding ring 3 is forward tapered, the upper hole section of the grinding ring 3 is reverse tapered, the tapered core 222 is forward tapered, the upper end of the tapered core 222 penetrates into the grinding ring 3 from the lower port of the grinding ring 3, and a conical grinding gap 10 is formed between the outer circumferential surface of the tapered core 222 and the lower hole wall of the grinding ring 3. This facilitates the entry of the coffee beans into the conical grinding gap 10, whereby the grinding stability is ensured.

As shown in fig. 16 and 17, the grinding cylinder 1 is provided with a rotation driving mechanism 8, and the rotation shaft 21 is drivingly connected to the rotation driving mechanism 8. This facilitates the rotation of the rotation shaft 21, thereby ensuring very convenient use.
