A bar clamp, including a bar; a first jaw movably coupled to the bar; a second jaw being movably coupled to the bar; and a motor configured to move the second jaw toward the first jaw. One of the first and second jaws including a drive lever that engages the bar and a trigger to move the drive lever and move the bar relative to the one of the first and second jaws.

A clamp accessory including a support element comprising a mounting surface adapted to rest on a work surface, the support element formed with at least one notch adapted to receive therein a bar of a bar clamp and support the bar at a distance spaced from the work surface.

A mechanism includes a first push button at one side and a spring-biased second push button at the other side such that pressing the first push button will lock a slide bar of a vise and a fixed jaw carrier thereof by inserting a first pin of the first push button into one positioning hole of the slide bar, pressing the second push button to insert a second pin thereof into one positioning hole by pushing the first pin out of one positioning hole with the spring being compressed, and releasing t...

The present invention relates to bar clamps, and more specifically, to attachments for extending the length of such clamps and enabling such clamps to be adaptable to a wider array of clamping needs. The accessories include an extension bar, a coupling that attaches one end of the extension bar to the clamp primary bar locking the bars in longitudinal alignment, and a stop that attaches to the primary bar or extension for fixing the location of a clamp jaw along the bars.

An electrically driven press tool that is compact, reliable and cost-effective. There is a press tool in which a crimping tool is retained in a recess by a bolt. An electromotor drives a spindle, which interacts with the crimping tool, by a reducing gear. The spindle is connected to a shaft by a pressure flange. The bearing pressure, which acts on the spindle, is brought to bear on a pressure ring by a pressure flange and a pressure bearing, the ring acting directly or indirectly on a force or p...

A clamping fixture includes a gauge rod having a fixed and a movable jaw mounted thereon, a lever-like handle, and a shift plate having a lower slot, via which the gauge rod is extended. The shift plate is connected to a rear side of the movable jaw via two shafts having compression springs mounted thereon. When the handle is downward pulled, a roller on the handle pushes the shift plate to turn clockwise, bringing the slot into an inclined position to firmly press against the gauge rod and ther...

The present invention is directed generally to tools that are high quality, strong, and lightweight. For example, various tools such as clamps may be made using parts containing a compound or alloy including magnesium. Magnesium may be for cast or extruded parts. In one embodiment, an "F" style clamp may be made with one or both of the two cooperating jaw members or sections being cast from a magnesium compound or alloy. In one variation, the "F" style clamp may include a shaft made from extrude...

An apparatus for securing a workpiece comprising first and second clamp members, and a transportable elongate member to which the clamp members are mounted and are operable for being shifted between work engaging and work releasing positions. In one form, the apparatus may be configured with clamp members capable of being fully removed from the elongate member and placed back thereon while maintaining the operability of the clamp members. At least one of the clamp members may be capable of being...

A setting tool conveniently grips a jewelry finding while providing a person working on the finding with maximum accessibility to it. The setting tool comprises a handle and a lockable cam for moving a pair of clamps radially of the handle axis between opened and closed positions. A variety of interchangeable clamp jaws are provided. The jaws are designed to accommodate a wide range of finding sizes and shapes. In one embodiment, the jaws cooperate with a moveable anvil to hold a pierced type ea...

A hand clamp includes a housing having a handle for being held by a hand of a user, a piston rod slidably received in the housing, a driving lever engaged in the housing and having an opening for slidably receiving the piston rod and biased to grip the piston rod when the driving lever is tilted relative to the piston rod. A trigger is pivotally attached to the housing and has a driving shaft for tilting the driving lever to move the piston rod step by step. A braking lever is slidably engaged o...
