Aspects of the disclosure relate to a sliding clamp including a first arm with a first jaw attached to the first arm, and a second arm with a second jaw attached thereto. The first jaw includes at least one first clamping ball freely rotatable relative to the first arm, and the second jaw includes at least one second clamping ball freely rotatable relative to the second arm. The second arm is configured to move relative to the first arm to adjust a jaw opening between the at least one second clamping ball of the second jaw and the at least one first clamping ball of the first jaw. The sliding clamp is configured to constrain a workpiece to a clamping plane while permitting translation of the workpiece within the clamping plane.

A versatile clamp assembly that may be used for securing a device generally to an edge of a structure such as a raised portion of a standing seam of a metal roof. The assembly comprises a mounting body with an open loop having a slot for receiving the raised portion formed by the mounting body attaching the clamp assembly thereto. The assembly is configured with one or more pins that may be configured to be received in one or more push-pin openings formed in the mounting body, whereby the push-pin openings extend from a fastener base portion to a second arm portion. The assembly includes a fastener adapted to be received in a fastener opening formed adjacent the push-pin openings. The fastener is configured to secure and hold the clamp assembly to the standing seam by forcing the pins against the raised portion of the surface disposed in the slot.

A woodworking clamp having a connector is provided. Two ends of the connector are connected with two clamping members to constitute the woodworking clamp. The connector includes a housing, a receiving tube, a U-shaped buckle, a spring, and a button. When the end of a bar of the clamping member is fully inserted in a notch of the U-shaped buckle, the spring provides a force to return the U-shaped buckle to its original position to complete the locking. When the button is pressed down, that is, a hook of the U-shaped buckle is pressed down, a positioning pin of the bar is released from the receiving tube and the U-shaped buckle so that the bar of the clamping member can be pulled out from the connector.

The apparatus (1) for clamping workpieces on machine tools comprises: a basic frame (2) fixable to a machine tool (M) for machining a workpiece (P); a clamping unit (3); a hydraulic actuator (22, 23) comprising a first chamber (26) which can be supplied with a first pressurized hydraulic fluid and is connectable to a first sensing device (27) for sensing the pressure of the first hydraulic fluid; a sensing channel (15) which can be supplied with pressurized air and which is connectable to a sensing sensor (16) for sensing the pressure of the air;
wherein the first sensing device (27) and the sensing sensor (16) are connectable to a control system adapted to authorize the machining of the workpiece (P) when the pressure of the first hydraulic fluid and the pressure of the air are simultaneously higher than their respective threshold values.

A clamping device has an actuator that moves linearly and is actuated by a drive. A pivoting clamping element is operatively connected, via a toggle lever mechanism, with the actuator. The toggle lever mechanism includes a drive-side adapter and a hand lever-side adapter. The drive side adapter and hand lever side adapter can be adjusted relative to one another to define an opening angle of the clamping element. One of the adapters has a profiled bar extending in a direction of actuation. The other adapter has an insertion region to accommodate the bar. A fixing element is provided in one of the adaptors to define the location of the adapters relative to one another. The fixing element can be clamped against the profiled bar and also against an insertion region.

The Trapdoor Clamp is the only product of its kind that allows individuals to safely place tools onto a highly adjustable platform to improve functionality of modern aerial lifts. The Trapdoor Clamp is uniquely designed with durable materials like rubber and metal to withstand force and ensure sustainability during operation. The clamp includes a channel having three sides defining open ends thereto, a trapdoor configured to create an open ended box with the three sided channel, a hinge configured to lengthwise join the trapdoor with the three sided channel, a trapdoor extension from the trapdoor, a stationary extension from the three sided channel configured to be in an opposing relation with the stationary extension and a fastener configured to put the trapdoor extension and the stationary extension in a compression.

A clamping system that includes a first jaw, a second jaw—the second jaw being pivotally connected to the first jaw—a locking handle pivotally connected to the first and second jaws, an adjustment element, first and second lever arms, and a release lever secured to the locking handle and configured to move the locking handle away from the first jaw.
