Abstract
A grinding tool operable with single hand includes a housing capable of standing upright, a lever, a one-way mechanism, and a grinding mechanism; the lever has an inner end formed with gear teeth, and is pivoted to the housing, and biased outwardly of the housing by a spring to be capable of being pushed and released repeatedly; the one-way mechanism has an actuating gear engaging the inner end of the lever, and a one-way bearing; the actuating gear is engaged with the bearing for causing angular displacement of the bearing together with it only when it is turned in a first direction by means of pushing the lever inwardly of the housing; the grinding mechanism includes an inner wheel turnable together with the bearing, and a stationary outer wheel around the inner wheel so that the contents can be ground between the wheels when the lever is pushed and released repeatedly.
