The invention relates to vise pivotal jaws for holding irregular shaped objects and that are modular to work on various sized prior art vises. Also relates to pivotal jaws having aid to return back to a neutral center position. The design allows ease of disassembly for cleaning and reassembly.

A key clamp for a key cutting apparatus is provided. The key clamp comprises a first jaw and a second jaw. The first jaw comprises an engagement surface having a widthwise dimension and a lengthwise dimension. The engagement surface comprises a first row of serrations, arranged along a lengthwise edge of the engagement surface, and a second row of serrations. The second jaw has an engagement surface comprising a row of serrations for location, in the widthwise dimension, between the first row of serrations in the first jaw and the second row of serrations in the first jaw.

A clamping unit (1) for clamping a workpiece, with an electric drive, and a gearbox unit having an arrangement of rolling elements (9). The gearbox unit is used to convert a rotary motion of an actuating element into a translational motion. By means of translational motions of the actuating element, clamping elements (5) can be moved into a clamping position in which a workpiece is clamped with clamping elements (5), and into a release position in which clamping elements (5) release the workpiece.

A woodworking vise includes a profiled vise body (1), a first jaw (2) and a second jaw (2′). The first jaw (2) and the second jaw (2′) are disposed at both ends of the vise body along its longitudinal axis. The woodworking vise further includes at least one movable jaw (3). The at least one movable jaw (3) is slidably connected to a top surface of the profiled vise body. Between the movable jaw (3) and the top surface of the profiled vise body (1), a locking block (36) is disposed, and a bottom surface of the locking block (36) is slidably connected to the top surface of the profiled vise body (1). The movable jaw (3) includes a force applying means (34) and a camshaft (35). The camshaft (35) has at least one cam, and the force applying means (34) is connected to the camshaft (35). Moreover, the force applying means (34) is able to rotate about a center axis of the camshaft (35) to drive the camshaft (35) to rotate therewith to cause the cam of the camshaft (35) to press against the locking block (36) and, by means of the locking block (36), press and secure the movable jaw (3) against and to the top surface of the vise body (1). Wherein, the center axis of the camshaft (35) is perpendicular to the longitudinal axis of the profiled vise body (1). This woodworking vise can solve the problem of an angle of clamping deviation.

An embodiment of a vise may include a clamping structure having a first clamping jaw, a second clamping jaw positioned relative to the first clamping jaw, and a quick adjust jaw guide to maintain the first clamping jaw relative to the second clamping jaw. The quick adjust jaw guide may include a driving element to apply a force to move the first clamping jaw relative to the second clamping jaw, wherein the driving element comprises a release structure to release the applied force to facilitate rapid adjustment of the first clamping jaw relative to the second clamping jaw.

A workpiece clamping device having at least one base body. A first clamping body and a second clamping body are movably supported on the at least one base body in a clamping direction. A threaded spindle extends along a spindle longitudinal axis. The spindle longitudinal axis is orientated in clamping direction. It has a first thread section for the first clamping body and a second thread section for the second clamping body. A first coupling body has a first counter thread portion and a second coupling body has a second counter thread portion. In a coupling position the counter thread portions are in engagement with the assigned thread section respectively. In a decoupling position the counter thread portion is disengaged from the assigned thread section. In this decoupling position a movement of the clamping bodies is possible without rotation of the threaded spindle.

An apparatus for converting a single-station vise to a double-station vise includes a pair of end converter jaws, a central converter jaw, and two pairs of shafts configured to extend along opposite sides of the single-station vise. Each of the shafts in the first pair is mounted for sliding movement relative to the first end converter jaw and fixed with respect to the second end converter jaw; each of the shafts in the second pair is fixed relative to the first end converter jaw and mounted for sliding movement relative to the second converter jaw; and all of the shafts are mounted for sliding movement relative to the central converter jaw.

A vice jaw deflecting structure, comprising a vice main body, a lead screw positioning seat, a lead screw, a first flexible jaw set and a second flexible jaw set; the guide slot of the vice main body has a bottom surface, a first side wall surface, and a second side wall surface; the first flexible jaw set and the second flexible jaw set have a slide, a jaw and a limiting component; the slide is configured with a limiting block protruding toward the jaw, the limiting block protrudes toward the lead screw positioning seat and is formed with a -shaped stop block having a curved top view; the jaw bottom surface has a first convex wall surface and a second convex wall surface matching and contacting the first side wall surface and the second side wall surface.
