Nutcracker, has nut crushed between cylinder and piston provided inside casing and both movable by pressing together two handles

摘要

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).
