The present application discloses a clamp and relates to the field of manual tools. A first clamp body and a second clamp body, which are comprised in the clamp, intersect and are fastened by means of a pivot mechanism, form a jaw opening at one end of a pivot mechanism, and have respective handles at the other end of the pivot mechanism. A stop mechanism is disposed at any position on the first clamp body and/or the second clamp body to prevent the two handles of the first clamp body and the second clamp body from further closing. In the clamp of the present application, the stop mechanism is disposed to prevent the handles of the clamp from completely closing when the clamping opening slides or is accidentally detached from a workpiece, thereby protecting a hand from being easily injured.

A clamping device has a clamping member (2) moveably mounted in a main body 1. A linearly movable actuator (3) is operatively connected to the clamping member (2). A spring element (4) is operatively connected to the actuator (3). A rotatably mounted actuating element (5) is operatively connected to the spring element (4). The spring element (4) is a compression spring that can be compressed when tensioning by the actuating element (5).

A clamping device includes first and second clamping components and at least one elastic component. The first clamping component includes a first clamping portion and two first pivot portions connected to the first clamping portion. The second clamping component includes a second clamping portion and two second pivot portions connected to the second clamping portion. The second pivot portions are pivotally connected to the first pivot portions respectively, such that the first and second clamping components are capable of rotating relative to each other to present a first state and a second state. The elastic component is connected to the first clamping component and the second clamping component. When the first and second clamping components are in the second state, the elastic component provides an elastic force for the first clamping portion and the second clamping portion to be restored to the first state to clamp an object.

Method and apparatus for sharpening a cutting edge of a cutting tool, such as a kitchen knife. A fixture secures opposing sides of a blade of the cutting tool and includes a main body and hinged first and second clamping jaws each having a clamping end adapted to compressingly engage a respective side of the blade. A guide coupled to the main body has converging support surfaces to contactingly engage a back edge (spine) of the blade opposite the cutting edge to center the blade along a central plane of the fixture. A retraction mechanism establishes a clamping force upon each of the respective sides of the blade via the clamping jaws. Further embodiments include a base assembly adapted to receive the fixture, and a swing arm style abrasive assembly to carry out a sharpening operation upon the cutting edge.

A quick-release clamp for a vehicular mount or rack having a rigid stationary first jaw with a clamping surface, and a rigid second jaw opposite with a clamping surface oriented to face the first jaw clamping surface. The second jaw is movable between an open and a closed position relative to the first jaw, where the closed position is capable of retaining one or more objects to be clamped transversely between said jaws. A lever, attached to a variable tensioning system operates to open and close the jaws when sufficient force is applied to overcome the tension of the tensioning system.
