A straight edge bar clamp spreader comprises a straight edge bar, an inner channel portion, parallel channel portions, and two-way bosses or divots, a clamp, and a clamp-spreader. The inner channel portion is provided along an elongated central region of the bottom surface of the straight edge bar with a constant cross-section. The parallel channel portions are provided along two elongated parallel regions of the top surface of the straight edge bar. The two-way bosses or divots are provided across and on an inner surface of the inner channel portion of the bottom surface and an outer surface of the top surface and configured to define the predetermined stopping positions for two-way movements along the bottom surface or the top surface. The clamp is installed in the inner channel portion of the bottom surface. The clamp-spreader is installed in the pair of parallel channel portions of the top surface.

A clamping tool includes a strut having one end and defining a longitudinal axis. Arranged on the one end of the strut is a mount which includes a bushing that is arranged on the strut. The bushing includes recesses and a receptacle which interacts with the recesses so as to be rotatably mounted in the bushing. The bushing has an interior provided with at least one groove for receiving an O-ring which is sized to extend beyond the groove to inhibit a rotational mobility of the receptacle. A clamping device is received in the receptacle of the mount and configured to swing about an axis perpendicular to the longitudinal axis of the strut.

A clamp assembly a fixed end support, a movable end support and a handle disposed in one end support or the other. The handle is rotated using an electric tool, such as a drill. A female receiver is disposed within a rearward end of the handle. A male driver is removably held within a chuck of the electric drill and is inserted into the receiver to rotate and then tighten or loosen the support end of the clamp. Alternatively, the clamp assembly has a male portion that is disposed at a rear portion of an end support and a female driver is used to rotate and then tighten or loosen the clamp from the wood pieces. The female receiver and male driver can be used with either a movable end support or a stationary end support of the clamp, as could the male portion and the female driver.

Embodiments disclosed herein generally relate to a pivotable clamp or vise. For example, the vise may clamp or secure a workpiece at a suitable position and/or orientation.

A locking assembly for locking a portable electronic device to a work surface. The locking assembly comprises a clamp assembly including an elongated bar that extends between a first end and a second end. The clamp assembly further includes a first jaw and a second jaw movable along the elongated bar for clamping to a work surface between the first and second jaws. A connector extends from a first connector end that is pivotally connected to the locking assembly to a second end that can be connected to the portable electronic device. The connector securing the portable electronic device to the work surface while permitting it to pivot with respect to the locking assembly.

A device for clamping a piece of formwork includes a bar having an end for attachment to a body. The device includes a jaw mounted on the bar and for receiving the piece of formwork, the jaw being movable along the bar.

A massage gun mounting system, includes a massage gun mounting device, including a structure connector with right and left clamp portions; and a massage gun holder with right and left holder portions, such that the structure connector connects to a mounting structure; such that a handle of a massage gun device is insertable into the massage gun holder, such that a user is enabled to apply pressure to a massage delivery member of the mounted massage gun device.

A locking pin tool to facilitate removal and/or installation of locking pins of a well head assembly includes an elongated shaft and a jaw assembly configured for engaging an end of a locking pin. A hammer body is mounted on the shaft and is movable along the shaft. A hammer stop provided on the shaft t engages the hammer body to absorb a striking force from the hammer body as the hammer body is moved along the shaft towards the hammer stop. By moving the hammer body along the shaft, the hammer strikes the hammer stop to impart a force on the locking pin to facilitate removal or installation of the locking pin.

A rail support system includes a clamp side having a channel with a first side and a second side, the first side and second side to engage around a post; an extension extending away from the second side; a plate engaged with the extension; a tightening screw engaged with the plate and further engaged with the first side; tightening the tightening screw pulls the first side and the second side together; 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 is to receive a rail; the clamp side is to secure to post while the cradle side is configured to engage with the rail such that the post and the rail are held in position for welding together.

A power tool assembly includes a base having a work surface, which is configured to receive a workpiece. A workpiece clamp assembly is moveably mountable on the work surface. The workpiece clamp assembly has a moveable clamp mount configured to fix the workpiece claim assembly in a plurality of different positions on the work surface, a clamp arm being operatively engageable with the moveable clamp mount and configured to move in a direction towards the fence, and at least one locking pin moveable between a first position and a second with respect to the moveable clamp mount wherein in the first position the at least one locking pin is configured to fix the workpiece clamp assembly to the base and in the second position the at least one locking pin is configured to release the workpiece clamp assembly from the base.
