A vise having a modular construction that allows for ease of manufacture, assembly, and changeover or replacement of wear items, such as gripping surfaces of jaws of the vise. The modular construction also provides for reduced weight of the vise compared to conventional cast type vises. The vise also incorporates quick adjustment features allowing for the vise to be easily rotated, a position and size of an opening of the jaws to be rapidly adjusted, and a clamping force applied with ease.

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.

A dual-cam device is described configured to be engaged with a rail and a stopper for clamping at least one object. The dual cam device comprises a jaw; a body; a member connecting the jaw and the body wherein the member has a member-base configured to associate with and slide on the rail; and a lever pivotally connected to the member, wherein the lever has a first cam and a second cam and wherein the lever is configured to be tilted from an open position to a clamp position and vice versa. During tilting the lever from an open position to a clamp position in which the object is clamped, the first cam causes the dual cam device to secure emplacement position of the dual cam device to the rail and then the second cam causes the dual cam device to press and clamp the object by the jaw against the stopper. It is further described a clamping apparatus that comprises at least one dual cam device; at least one rail having a channel; and at least one stopper.

A slider bar extender to removably connect one or more slider bars to a processing machine or tool is disclosed. In illustrated embodiments, the extender is coupled to a holder structure through a tongue and groove connection. In illustrated embodiments, the tongue is formed on the holder structure and the groove is formed on the extender. In illustrated embodiments, the extender includes a plurality of reduced thickness strips. The reduced thickness strips are orientated lengthwise to control or transfer bending to one or more bars connected to a proximal edge surface of the extender.

A workpiece clamp device capable for changing clamp angle is arranged on a base plane and comprises a first and a second movable blocks, a driving block, at least one first and at least one second elastic members, at least one first and at least one second cylinders, and at least one third and at least one fourth elastic members. Since the first and the second cylinders are slightly rotatably and detachably respectively embedded in the first and the second embedding grooves to make the first and the second rough surfaces be exposed and the elasticity of the third and the fourth elastic members is cooperated therewith, the first and the second rough surfaces are slightly fine-tuned based on the shapes and sizes of the workpieces so as to be suitable for clamping and fastening the workpieces with different shapes.
