The present invention relates to a straight edge clamp that has a clamping head assembly and a stop assembly mounted upon the body of the straight edge. The head and stop are not connected together and the stop assembly is free to move with respect to the head assembly. The straight edge clamp body includes at least two sections that are hinged together to allow the sections to be folded upon one another when not in use and unfolded when in use.

A modular side-by-side vise structure comprises a base, a fixture block group located on the base, and a side clamping piece group; the side clamping piece has an upper part and a lower part, and a bolt is screwed in the upper part to prop the lower part, so that the stopper and movable fixture block cling to the base tightly; or the side grooves on both sides of the stopper and movable fixture block are provided with bolt holes, and the inner wall of side clamping piece is provided with a punch hole, the bolt is screwed in the bolt hole through the punch hole, so that the stopper and movable fixture block cling to the base tightly. Therefore, it is unnecessary to hold up the side clamping piece with a hand while tightening or loosening the bolt, favorable for the technician to implement quick assembly or disassembly.

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 pipe clamp has a base with a fixed jaw and a beam extending from the base. A movable jaw member is slidably mounted on the beam. The movable jaw member includes a movable jaw disposed opposite the fixed jaw. A pivotable handle is mounted to the movable jaw member and a clamping mechanism is connected to the pivotable handle and operated by the pivotable handle to move the movable jaw relative to the fixed jaw. A latch secures the pivotable handle in any of a plurality of positions. A tripod stand may be provided for supporting the pipe clamp, the tripod having a multi-compartment storage spreader.

The present invention relates to an integrated vise and work table. The disclosed vise table allows an operator to clamp an object in place so that the same can worked on in a hands-free method. The vise table includes a table block, a vise head block, a threaded guide, a rotator, and an activation mechanism that allows the operator to selectively vise in a threaded mode or in an unthreaded mode. In the threaded mode, the vise head block may only be moved by rotating a threaded guide. In the unthreaded mode, the vise head block may only be moved by applying force to the vise head block in the desired direction of movement.
