The present invention relates to a hand-cranked grinder and a folding crank thereof. The crank comprises a rotating structure, a handle and a locking structure, the locking structure being used for fixing the handle to a working state or a storage state, and the handle comprising a cantilever; when in the working state, the cantilever is parallel to the plane where the rotating structure is located, and drives the rotating structure to rotate, so as to drive a hand-cranked grinder main shaft to rotate for grinding; when in the storage state, the cantilever is perpendicular to the plane where the rotating structure is located, so as to be stored. The folding crank of the hand-cranked grinder in the present invention can provide large grinding torque and is foldable, allowing more labor-efficient grinding, smaller occupied space, and convenient storage.
