Manual grinder

A portable manual grinder, comprising:

• a driving section, a grinding section and a discharging section each coaxially connected to one another;
• the driving section includes a drive shaft driving a central axis of the grinding section;
• the grinding section includes an upper grinding section and a lower grinding section that are coaxially disposed and mated together;
• the upper grinding section includes an upper blade group and the lower grinding section includes a lower blade group, and the upper blade group and the lower blade group are respectively composed of a plurality of upright blades arranged in a circular shape;
• the bottom section of the lower grinding section one or more holes communicating with the discharge section;
• the driving section and the upper grinding section are magnetically attracted and connected to each other by a first magnetic material provided on each of them at corresponding positions;
• the upper grinding section and the discharge section are respectively coaxially provided with a second magnetic material such that the upper grinding section and the lower grinding section are magnetically attracted and connected to each other;
• wherein the discharging section comprises a funnel bin with fan blades disposed in the funnel bin;
• an outer wall of the funnel bin is connected to an outer wall of the lower grinding section;
• a fan shaft is formed at the center of the fan blades and extending upwardly;
• the fan shaft is received in the rotating shaft of the upper grinding section;
• the second magnetic material is embedded on the top end of the fan shaft;
• and the drive shaft sequentially connects the rotating shaft of the upper grinding section and the fan shaft, driving the upper grinding section and the fan blades to rotate.
