The present invention is generally directed towards clamps for high tension load applications. In particular, the invention relates to high holding power clamps in which fabric can be secured, and which can withstand a large amount of force, including, in at least some embodiments, the maximum amount of tension permitted in various modern high strength fabrics and/or fiber weaves. In at least one embodiment, a holding clamp has a single-V design, with at least three areas that exert pinching effects on fabric held in the clamp, and at least four capstan areas that exert capstan effects on the clamped fabric. In at least a further embodiment, a holding clamp has a double-V design, with at least six areas that exert pinching effects on fabric held in the clamp, and at least seven capstan areas that exert capstan effects on the clamped fabric.

Embodiments relate to a restraint and stowage device comprising a fixed jaw and a movable jaw, wherein the fixed jaw is attached to an elongated rod. The elongated rod may be receivable through an aperture of the movable jaw. The movable jaw is positioned along the elongated rod such that an object may be securely restrained between the movable jaw, the fixed jaw, and the elongated rod. The position of the movable jaw may be fixed by an end piece.

Provided is a compressible cam lever that has a section that can be compressed by external force. When the external force is released, elastic force within the cam lever causes the section to return back to its original position creating a spring force. The compressible cam lever may be used as part of a handle for opening and closing a clamp that is part of a tripod or other piece of equipment which can hold rails for firearms, sights, scopes, parts, and the like, therein. The compressible cam lever may include a handle, a round-shaped section comprising a flexible curved surface that curves back towards the handle and protrudes outward, and an opening disposed between an end of the flexible curved surface and the handle.

A clamp including a first jaw member having a camming surface, a second jaw member pivotable with respect to the first jaw member, a first biasing member biasing the first and second jaw members to a first position; and a locking mechanism that includes a cam or roller for cooperating with the camming surface of the jaw member, and a second biasing member biasing the cam or roller against the camming surface to lock the first and second jaw members in a second position. An optional alignment collar can be used to align components of the filtration apparatus prior to clamping. Filtration apparatus including the clamp, and also optionally including the alignment collar, is also disclosed.

A precision clamping assembly has a body, two clamping arms, and a drive device. The body has a first direction, a second direction, a chamber formed in the body, and an opening formed through an outer side of the body along the second direction and communicating with the chamber. The clamping arms are pivotally and movably connected to the body, and each clamping arm is disposed in the chamber and has a pivot end and a clamping end extended out of the body via the opening. The clamping ends are selectively moved toward or away from each other along the second direction and selectively moved same or opposite from each other along a third direction. The drive device is connected to the body and the two clamping arms, and has two driving sets disposed in the body and respectively connected to the two clamping arms.

A clamping and locking device that uses two main parts. The two parts are connected by an axle, which acts as a fulcrum. The assembled clamp has jaws that meet together on one end of the assembled parts. There is a multi-radius latching system on the inside of the handle arms located on the other side of the axle. The handle arms may be straight or curved. The ends of the handle arms can be straight, or have hooks, ring-holes, hand-grips, or an assortment of other useful end-of-handle designs.

An expandable fixture contains: a first body, a second body, and an actuation rod. The first body includes a first clamp and a grip. The second body includes a connection structure, and the second body includes a second clamp. The first body further includes a drive mechanism configured to pull the actuation rod to drive the first clamp and the second clamp to clamp, a press extension configured to control the drive mechanism, and a first positioning structure vertically corresponding to the actuation rod. The second body includes a second positioning structure rotatably connected on a peripheral side thereof, and each of the first positioning structure and the second positioning structure is a respective one of two T-shaped posts slidably mounted on a respective one of two T-shaped slide rails of a work table.

A clamping device includes a cylinder, a base body, a movable plate, and holding pins. The movable plate is attached to the base body substantially parallel thereto via two pairs of link arms. The movable plate moves along the operating direction of the cylinder. The movable plate can abut against a width-direction side surface of a workpiece. The holding pins are attached to the movable plate. The holding pins abut against an upper portion of the workpiece.

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 retrieval device may include a first plate and a second plate which may be movably coupled to a body via a first body fastener and a second body fastener, respectively. An upper plate connector and a lower plate connector may each be movably coupled to the first plate and a second plate with the lower plate connector positioned between the upper plate connector and the body fasteners. An optional tensioner may tension portions of the first plate and a second plate together. Upper gripper(s) may be coupled to the upper plate connector and lower gripper(s) may be coupled to the lower plate connector. The device may be movable between an open position, in which the upper gripper(s) and lower gripper(s) are positioned relatively distally from each other, and a closed position, in which the upper gripper(s) and lower gripper(s) are positioned relatively proximate to each other.
