A device for connecting two clamps, each of which has a rail, including a housing that has two insertion openings, which point away from each other and each of which has an adjoining insertion channel, for inserting a respective rail. The device also includes at least one adapter piece which can be inserted into one of the insertion openings and which reduces the free opening cross section of the insertion channel in order to insert a rail with a different cross-sectional area. The adapter piece has a lining which adjoins a collar. The lining rests against the wall of the insertion channel at least in some regions and forms an insertion channel with a reduced cross section in the inserted state, and the collar rests on an end face of the housing.

According to an embodiment, a bar clamp includes a bar, a fixed jaw, and a movable jaw assembly having an actuator portion and a jaw portion. The movable jaw assembly is configured to move along the bar towards or away from the fixed jaw. At least one of the actuator portion and the jaw portion is configured to rotate around the bar. According to another embodiment, where a bar clamp comprises a bar, a fixed jaw, a movable jaw, and a movable jaw actuator, a method of operating the bar clamp includes rotating one of the movable jaw actuator and the movable jaw about the bar while the fixed jaw and the bar remain stationary, and using the movable jaw actuator to move the movable jaw along the bar towards or away from the fixed jaw.

Pliers 1 comprising fixed and sliding jaws 207, 300 operated by fixed and moving handles 200, 400 wherein a force triangle 800 is formed with its base 801 between the sliding jaw 300 pivot pin 600 and the pivotal strut 500 pivot pin 601, the triangles apex 802 formed within the pivotal strut outer end pivot bore 504. As the operator clenches CF the moving and fixed handle grips 408, 213 said force triangles apex 802 is propelled towards said triangle base 801, forcefully elongating said base 801, forcing the sliding jaw 300 towards the closed position, the sliding jaw 300 incorporates roller pins 600, 601 ensuring ease of movement upon the fixed head parallel rail 205. The fixed handle 200 incorporates two fold out arms 218, which can form part of a three legged base allowing use as a portable vice. The moving handle 400 can incorporate a further locking rocker switch 700 that can be utilised in both a switchable locking position or non-locking position upon a correspondingly toothed fan 505 within the pivotal strut 500 between said handles 200, 400.

A spring powered bar clamp has a sliding jaw longitudinally movable along a longitudinally extending bar. The sliding jaw extends forward of the bar. A first handle is fixed to the bar and extends rearward. A second handle is attached pivotable relative to the bar and the first handle about a first axis positioned at a location forward of the bar. The clamp includes a non-sliding jaw attached to the second handle in a pivotable engagement about a second axis positioned forward of the first axis. A spring biases the upper handle and lower handle away from one another. Embodiments exist that utilize a torsion spring or a coil spring for biasing the handles away from each other. The clamp can be lockable in a pre-loaded position wherein the spring is compressed and the handles are prevented from separating, and then unlockable from the pre-loaded position to clamp a part.

A one-handed ratchet clamp tool includes a slide rod, a fixed arm, a movable arm, an operation lever, a clam member, and a release member. The fixed arm is disposed on one end of the slide rod. The movable arm has one end slidably mounted around the slide rod, and another end having an imaginary face and a ratchet which include a dip angle larger than 30 degrees. The operation lever is pivotally disposed on the movable arm. The clamp member is movably disposed on the operation lever, which optionally presses the clamp member, clamping or releasing the clamp member and the fixed arm. The release member is connected with the operation lever and has a pawl, which is engaged with or disengaged from the ratchet to position the operation lever or allow the operation lever to sway away from the movable arm. Convenience of one-handed operation is facilitated.

A lifting and lowering tool includes a foot configured to be supported on a surface, a bar extending therefrom, and a movable assembly including a housing, a movable platform shaped to support a load that extends from the housing, a lifting actuator configured to incrementally move the movable assembly along the bar away from the foot, a lowering actuator configured to incrementally move the movable assembly along the bar towards the foot, and a release actuator configured to disengage the movable assembly from the bar to allow free movement of the movable assembly along the bar. In embodiments, the movable assembly engages the bar through locking plates that extend through a flange of the movable assembly. In embodiments the release actuator is spaced from the lifting actuator and the lowering actuator to prevent inadvertent actuation of the release actuator. In embodiments a flange of the movable assembly surrounds the bar.

The present invention discloses a self-holding clamp, comprising a sleeve, an operating member, a tension spring, and a threaded button. The sleeve forms a cavity extending to both ends of the sleeve, and the outer side of the sleeve forms a first clamping jaw. The operating member is configured within the cavity, wherein one end of the operating member protrudes from the sleeve to form a second clamping jaw, and the other end of the operating member protrudes from the sleeve to form a threaded segment, allowing the first clamping jaw and the second clamping jaw to clamp an object in opposition. Furthermore, one end of the tension spring is connected to the sleeve, and the other end is connected to the operating member, thereby providing a clamping force for the first clamping jaw and the second clamping jaw to clamp the object in opposition.

A clamp assembly for a work carrier according to an example of this disclosure includes a base for mounting to the work carrier and including a rotatable spur gear. A slider includes a main housing, a rack with a plurality of teeth along an upper surface of the rack for engaging the spur gear for linear movement of the slider relative to the base, and a clamp extension extending from the main housing to engage an edge of the work object.

A massage gun holder with an elongated rail that attaches to a mounting surface and a shuttle that holds the gun and that can move longitudinally on the rail. At least one side edge of the rail has a linear gear. The shuttle has a body with a curved depression in the front surface for the gun handle. A handle clamp pivots to secure the handle of the massage gun in the depression. The shuttle slides on the rail in a vertical rail slot on the back of the shuttle body and is secured to the rail by a rail clamp. A cam mechanism moves the rail clamp between an engaged position, where studs in the side wall of the rail slot engage the linear gear, and an unengaged position, where the studs are disengaged from the linear gear.
