Abstract
A device for locking the micrometric adjustment of the degree of grinding in coffee grinders includes a hollow cylindrical casing for housing a lower grinding wheel carrier, which is connected to a motion transmission shaft, and for housing an upper grinding wheel carrier, which is axially movable; and a threaded ring nut engagable in the casing to adjust the position of the upper grinding wheel carrier, wherein the ring nut has at least one seat for inserting a peg for locking its rotation, and the casing has an undercut slot in which a slider cooperating with the peg is housed, the thickness of the slider being less than the thickness of the slot. A member engages the slider and causes it to rise and to interfere by friction with the upper wall of the slot.
