A clamping apparatus includes a shaft; a base body that is adjustable to different positions, e.g., heights, along the shaft; a clamping leg arranged to pivot into a first clamping position and a second clamping position; an arm that includes, and extends between, a first end portion connected to the base body and a second end portion connected to the clamping leg; and a handle configured to be moved (a) into a first position that locks the position of the base body relative to the shaft and provides a clamping force to the clamping leg, and (b) into a second position in which the base body is free to be shifted into different positions along the shaft, where moving the handle into the second position releases the clamping force.

A directional translating clamping device comprises a housing that includes a distal housing end and proximate housing end separated along a central axis, and a housing recess at the proximate housing end and extending along the central axis end. The device also includes a slide located in the housing recess, and the slide comprises a slide recess at a slide proximate end co-axial with the housing recess, and a detent in a radial sidewall of the slide prevents the slide from translating beyond a predetermined axial distance along the central axis. A spring is located in the housing recess and exerts an axial force on the distal end of the slide. A stub shaft extends from the distal end of the housing. A roller ball assembly includes a threaded sidewall that engages with the slide recess to removably and replaceably secure the roller ball assembly to the slide.

A multi-clamp stand apparatus for handsfree assistance includes a base having front side, a back side, a top side, and a bottom side. A support pole has a bottom end and a top end. The bottom end is coupled to the top side of the base. A clamp collar is coupled to the support pole and is slidably engageable on the support pole from the bottom end to the end. An adjustment mechanism is coupled to the clamp collar and is in operational communication with the support pole to fix and alternatively release the clamp collar and the support pole. An at least one clamp is coupled to the clamp collar.

An apparatus for unilateral spinal cord compression includes a fixed member and a movable member that moves longitudinally along the fixed member by using a linear actuating mechanism to compress a portion of spinal cord encompassed by the movable member and the fixed member.

An apparatus configured to assist an operator in connecting electrical connectors. The apparatus includes a first U-shaped cradle and a second U-shaped cradle. Each of the cradles has a contact surface on a front side that is configured to contact a flange on an electrical connector. Each of the cradles also includes a jaw mount configured to mount on a jaw member of a bar clamp.

The invention to which this application relates is a clamping mechanism of a type which is adapted to be used with a base (4). The apparatus (2) is provided for use in conjunction with a base (4) to exert a clamping effect on a workpiece (13) with respect to the base (4) and the clamp apparatus (2) includes an elongate shaft (14), a locating portion (52, 6) provided at, or towards one, end of the said shaft, a user operated actuation means selectively located between the said locating portion (52, 6) and the opposing end of the elongate shaft (14). The actuation means are provided with, or connected to, a clamping portion (12) and the locating portion (52, 6) is provided to allow location of the clamp apparatus (2) with respect to engagement means provided on the base (4).

The main fixed handle optionally incorporates two swivel out arms, which can form part of a three-legged base. When operated thus, the jaws and moving handle point generally upwards from the formed base, the moving handle can now be operated by one hand leaving the other free to position the workpiece. The moving handle can incorporate a further locking switch that can be utilised in both a switchable locking position or non-locking position upon a sprung toothed strut between the handles, at least one of which further incorporates a curved resilient portion in order to provide useful sprung closure of the parallel moving jaws upon the workpiece in the locking method. A lanyard can be optimally attached to the swivel out arm ends to provide the user with a chest mounted portable vice.

An anti-pivot and lock mechanism for a clamp including a horizontal post connected and moveable relative to a vertical post. The mechanism engages the vertical post and horizontal post above or below a pivot axis of the horizontal post to prevent or minimize pivoting movement of the horizontal post between changes of consecutive clamped workpieces.

A pliers is provided, including a main body, a slidable member, a swingable assembly and a clamp assembly. The slidable assembly is attached to the main body. The swingable assembly includes a swingable member and a connecting member, and the swingable member is pivoted to one of two ends of the slidable member and one of two ends of the connecting member. The clamp assembly includes a firs clamp portion and a second clamp portion, and the first clamp portion is disposed on the slidable member.

A device for holding a wood log in place in such a way that a person can cut the log with a saw or split it with an axe is disclosed. The device can be attached to trees or vehicles to keep it in place and can be assembled and disassembled with relative ease. The device is configured to hold the logs between two support arms attached to a post and a grip member attached to each of the support arms. The post is configured for attaching to standing trees through extending arms or brackets and configured for position adjustments by way of sliding inside sleeves that attach to the post, bracket or a hitch of a vehicle.
