Abstract
An improved locking mechanism for a cutting tool (1) is disclosed. The locking mechanism includes a locking block (15) transversely located through or on one handle (12) of the cutting tool (1). The locking mechanism incorporates a shaped spring (18) adapted to restrain the locking block (15) in either the locked or unlocked position. A cutting tool (1) having a pair of handles (11,12) operable to move at least one cutting blade relative to a second cutting blade or anvil and including the locking mechanism described is also disclosed.
Claims16
A cutting tool having a pair of handles operable to move at least a first cutting blade relative to a second cutting blade or anvil and including a locking mechanism, wherein said locking mechanism includes a locking block transversely located through or on a handle of the first cutting blade, said locking block movable between a locked and an unlocked position in a direction transverse to the plane of rotation of the first cutting blade, said locking block being recessed to receive a shaped spring adapted to restrain the locking block in either the locked or unlocked position, wherein said locking block is movable relative to the spring, said locking block being apertured to permit part of the second cutting blade to pass through said aperture when the locking block is in the unlocked position.
A locking mechanism for a cutting tool, said mechanism being operable to resist exposure of a cutting edge of said tool and including a locking block transversely located through or on a handle of a first blade of the cutting tool, said locking block movable between a locked position and an unlocked position in a direction transverse to the plane of rotation of the blade and incorporating a shaped spring adapted to restrain the locking block in either the locked or unlocked position, and wherein the locking block is apertured to permit a portion of a second blade of said tool to pass through said aperture when the locking block is in the unlocked position.
A locking mechanism for a cutting tool, said mechanism being operable to resist exposure of a cutting edge of said tool and including a locking block transversely located through a handle of a first blade of the cutting tool, said locking block movable from a locked position to an unlocked position in a direction which is substantially normal to the plane of rotation of the blade and recessed to receive a shaped spring adapted to restrain the locking block in either the locked or unlocked position, and wherein the locking block is apertured to permit a portion of a second blade of said tool to pass through said aperture when the locking block is in the unlocked position.
