A pair of universal pliers includes a fixed structure, a movable structure movably connected to the fixed structure and including front and rear movable handle plates, and a quick release mechanism including a trigger and a resilient locking subunit. The resilient locking subunit includes a movable pin inserted through and slidable along a first guide slot of the front movable handle plate and a second guide slot of the rear movable handle plate. The resilient locking subunit is switchable between a locked state where the rear movable handle plate cannot pivot relative to the front movable handle plate and a non-locked state where the rear movable handle plate can pivot relative to the front movable handle plate.

A hand tool with a clampable operating area at an upper part of the tool, and two opposed handles extending to a lower part of the tool and being arranged to govern the clampable operating area between an open and a closed position, wherein a toothed pin is pivotally arranged between the handles extending downwards, wherein a support and a pawl are arranged on a first handle of the two handles at a distance from each other forming a space between them, in which space the toothed pin is to be received, and wherein an interaction of the toothed pin and the pawl impedes reverse motion of the handles during a closing action thereof, The interaction of the toothed pin and the pawl is such that reverse motion of the handles becomes possible at a specific release point that corresponds to a specific relative position of the handles.

A hand tool includes a handle assembly, a jaw assembly, and an adjustment assembly. The handle assembly may include a top handle and a bottom handle. The jaw assembly may include a top jaw and a bottom jaw. The top and bottom jaws may be operably coupled to the top and bottom handles to compress the top and bottom jaws toward each other responsive to compression of the top and bottom handles toward each other. The adjustment assembly may be configured to enable a grip size defined by the jaw assembly to be modified and includes a first adjuster disposed at a distal end of the top handle, a second adjuster disposed at a point between a middle portion and proximal end of the top handle, and an adjustment rod operably coupled to each of the first and second adjusters.

Crimping pliers are configured to crimp cable lugs onto electrical conductors. The crimping pliers includes first and second crimping jaws pivotally connected together, a first crimping matrix mounted for rotation on the first crimping jaw, a second crimping matrix mounted for rotation on the second crimping jaw, each crimping jaw having a plurality of different first crimping dies formed therein, and interlocks provided on the crimping jaws. The interlocks are configured to lock one of the crimping dies on each crimping jaw into a working position.
