Embodiments of a multi-purpose utility clamp may include a component engagement member having a clamp head and a handle. A guide arm is operatively connected to the component engagement member at a first end of the guide arm. A first post is operatively connected to a second end of the guide arm to move linearly relative to the guide arm. A second post at an end of the support post is disposed generally perpendicular to the first post and has a first end connected to the first post and a second end, distal the first end, and the second end is disposed opposite the clamping head. The second post has a generally trapezoidal cross-sectional shape along a length thereof between the first end and the second end, and the second post is configured to be inserted into a channel having a corresponding trapezoidal shape and formed in an auxiliary component to be clamped to another component.

An attachment device for attaching to a structural component of a building to couple a fitting to the structural component.

The present disclosure relates to a gripper device which comprises: a belt pulley driven by a power-driven motor; a belt and another belt pulley driven by the above belt pulley; a ball screw driven and rotated by the belt pulley; nut brackets driven to be shifted along two rigid guideways by two reverse threads at both sides of the ball screw, respectively; a plurality of steel balls, which are installed between a nut bracket and a rigid guideway and sustain more stresses when a workpiece is clamped between two upper slide on the nut brackets.

A pipe alignment clamp for use in pipe fitting/fabrication applications. The pipe alignment clamp has a generally circular frame with at least one hinge therealong to enable the clamp to be opened and subsequently secured around a pair of pipe segments and/or fittings to be joined. Threaded support members are positioned along the frame in spaced apart fashion, and extend outwardly from each side of the frame. The support members are used to support alignment screws that can be independently repositioned radially towards and away from the pipe segments and/or fittings to be joined, thereby enabling the alignment clamp to accommodate a wide variety of different shapes and sizes of pipe segments and fittings, and requiring a minimum length of pipe segment to operate. The adjustment screws may be manipulated by hand, or by a separate alignment screw tool, which may be included as part of a pipe alignment kit.

An attachment assembly for securing party decorations to support structures. The attachment assembly includes a clamp device to attach the attachment assembly to a support structure and one or more fastening mechanisms configured with the clamp device to secure party decorations. A first fastening mechanism includes a through-hole passing through the clamp device and a second fastening mechanism includes a rotatable clamp member biased against an outer surface of the clamp device. Party decorations, such as balloon tie strings, garland, streamers, ribbons, etc., are secured to the clamp device using the fastening mechanisms and the clamp device is securable to a support structure such as a railing, fence, table, etc.

Systems for cutting cylindrical workpieces such as pipe are described. The systems include a clamping assembly and can be used in various methods. In one method, the clamping assembly and a cutting tool or saw is used on a rotating workpiece. In another method, the clamping assembly and a cutting tool or saw is used on a stationary workpiece. Also described are frames that can be secured to the clamping assembly.

a medical fastening device for an electromagnetic sensor with a clamping element and with a sensor mount and to a medical device with such a fastening device, with an electromagnetic sensor and with a medical instrument. The clamping element has a counterpiece and a pressing piece movable relative to the clamping element, wherein the counterpiece has a lateral opening, which frees a free mounting area, which is itself at least partially enclosed by the counterpiece in a frame-like manner. The counterpiece has a depression, which points towards the mounting area and is arranged opposite the pressing piece, wherein the counterpiece is provided with an opening arranged opposite the depression. The pressing piece is movable in the opening in the direction of the depression of the counterpiece.

A rail support system includes a clamp side having a channel to engage around a post; an extension curved around the channel; a first bar engaged with the extension; a handle attached to the first bar; and a second bar attached to the first bar via a lateral connector; pivoting the handle causes the second bar to apply pressure to the second side of the channel; a cradle side having an arm attached to the channel and extending away therefrom; and a cradle support attached to and extending away from the arm, the cradle support being vertically adjustable relative to the channel; the cradle support is to receive a rail; the clamp side is to secure to the post while the cradle side is to engage with the rail such that the post and the rail are held in position for welding together.
