Abstract
A one-way pepper grinding tool includes an one-way member, and a grinding assembly having an inner and an outer grinding part. The one-way member has a main body turnably received in a housing. The main body has several curved slots around a central round hole. The curved slots each has an engaging end portion in open communication with the central round hole for permitting an engaging block movably received in the slot to separably engage a ring fitted in the central round hole; the engaging blocks being biased to the engaging end portions by springs to force the ring to turn together with the main body when the main body turns in a first direction, making the inner grinding part associated with the ring turn to grind pepper. When the main body turns in an opposite direction, the engaging blocks are moved away from the ring, not able to make the ring turn, i.e. the inner grinding part will not turn relative to the outer grinding part.
