The nut (6) is crushed between a first press surface (4) on a cylinder (3) and a second press surface (5) on a piston (28). Two symmetrically arranged handles (12, 13) pivotally mounted in the nutcracker housing (2) are pressed together to urge the piston and cylinder towards each other. The handles are pivotally connected to the piston via two link arms (16, 17), either directly or indirectly via a piston rod (18). |
