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 hand tool including a first jaw, a first handle fixed to the first jaw, a second jaw, and a second handle pivotally coupled to the second jaw. The hand tool further includes a link member having a first end pivotally coupled to at least one selected from the group of the first jaw and the first handle, and a second end pivotally coupled to the second jaw.

A tool comprising an outer body with a first end and a second end, the outer body defining a longitudinal recess therein and having at least two connector link pivot points at the first end thereof, an inner body slidably received within the longitudinal recess of the outer body and having a core head extending out of the first end of the outer body, at least two jaws, each jaw having an inner pivot point and an outer pivot point, wherein the inner pivot point of each jaw pivotally connected to a corresponding core head pivot point on the core head, a connector link for each jaw, each connector link having a first end pivotally connected to the outer pivot point of the jaw and a second end pivotally connected to a corresponding connector link pivot point on the first end of the outer body, and an actuating assembly for moving the inner body relative to the outer body, whereby movement of the core head toward the outer body causes the jaws to move toward each other, and movement of the core head away from the outer body causes the jaws to move away from each other.

An adjustable locking pliers includes a stationary handle, a stationary jaw, an operating lever and a movable jaw. The jaw is coupled by an axis which is selectively displaceable to alter the jaws' gripping capacity. The operating lever is coupled to the movable jaw by a first pivot. The lever rear forms a movable handle. A spring biases rotation of the movable jaw about the axis away from the stationary jaw. An actuation rod having a series of teeth and a stop face is coupled to the operating lever by a second pivot part way along the operating lever and coupled to the stationary handle by means of a third pivot. A catch having a series of teeth and a stop face is pivotally coupled to the operating lever. The teeth of the actuation rod and the teeth of the catch are configured to engage each other to permit multiple clamping positions.

Everyway Pliers 1 comprising fixed and pivotal gripping jaws 206, 301 operated by fixed and moving handles 200, 400 wherein a force triangle 800 is formed with its base 801 between the pivotal jaw 300 actuation pivot pin 60 land the fixed handle 200 to pivotal strut 500 pivot pin 601, the triangles apex 802 formed within the pivotal strut outer pivot bore 502 and moving handle central pivot point 402. As the operator clenches CF the moving and fixed handle grips 413, 212 said triangles apex 802 is propelled towards said triangle base 801, forcefully elongating said base 801, further forcefully rotating the pivotal jaw 300 towards the closed position around the pivotal jaw pivot bore 302, the combination of said rotational and elongation closure forces employed provides extremely robust gripping jaw 301, 206 closure, by one or smaller hands. Optionally incorporating interchangeable push fit jaws 900, utilizing near identical curved locking blade and abutment profiles 901, 902 with strong magnets 905 located within the jaw stub blade channel 903 tips, providing substantial initial interchangeable jaw 900 retention.

A system for attaching a PTO yoke to a tractor PTO output shaft comprises gripping a shaft of the PTO yoke using a clamp tool, whereby the clamp tool maintains a slide collar of the PTO yoke in a retracted position with respect to the yoke shaft, such that the yoke shaft is exposed for attachment to the tractor PTO output shaft. The clamp tool may comprise pliers, including plier jaws and plier handles; and a flexible band coupled to the plier jaws.

A pitch bar self-adjusting clamp including a fixture having a handle and an opposing stationary jaw, a co-acting jaw pivoted to the fixture, a lever pivoted to the co-acting jaw, a guide bar pivotally coupled to the handle proximate the stationary jaw and movably coupled to the handle, and a toggle assembly coupled between the lever and the guide bar. The toggle assembly includes a locking element, a link pivoted to the lever, and a cam pivoted to the link and to the locking element. The cam is movable between a first condition permitting the locking element to reciprocate along the guide bar and a second condition bearing against the guide bar and canting the locking element into frictional engagement against the guide. An adjustment mechanism is coupled to the proximal end of the guide bar for movement between a low pitch position and a high pitch position.
