Technical Field

[0001] The utility model belongs to the technical field of coffee bean grinders, and in particular relates to a coffee bean grinder with a stable bottom support. Background Art

[0002] There are two types of coffee bean grinders, one is manual and the other is electric. Manual coffee bean grinders are used for display at home or in stores. They are cheap, exquisite, and have a romantic feel, but they grind beans slowly and easily get hot. Electric coffee bean grinders grind beans quickly, can be used continuously, and can grind fine powder. Modern people prefer electric coffee bean grinders. When an electric coffee bean grinder is in use, the running of the motor will cause the grinder to vibrate, and the vibration will cause the grinder to move or even fall off the countertop, reducing the stability of the grinder.
