ABSTRACT:
A crusher comprises a housing defining a crushing chamber for restraining an object to be crushed and a plunger for applying force on the object to be crushed when the plunger is actuated by a handle. The handle is mounted on the housing for pivotal movement about a first floating pivot in a first pivotal direction which actuates a first engaging element to move the plunger in a first direction to crush the object in the crushing chamber. The plunger is locked against resilient return in a second direction by a second engaging element. Further pivotal movement of the handle about a second floating pivot in a second pivotal direction actuates the disengagement of the second engaging element, causing the return of the plunger.
