A pliers (1) has jaw portions (21) incorporating gripping faces for the clamping of the desired workpiece (80), two pivotal handle portions (22) and a sprung toothed strut (40) positioned between the handles (22, 301). A bow shaped resilient portion (304), incorporated within the second arm (20, 300) portion, when the pliers (1) are operated this resilient portion (304) imparts a useful superior sprung pressure upon the clamped workpiece (80) by the gripping face (26, 303) of the jaws (201, 21). The second arm (20, 300) and bend promoting portion are contiguous with each other. The jaws (201, 21) can be usefully locked in the required clamping position upon the workpiece (80) by a toothed sprung strut (40) pivotally attached to the first and second arms (20, 22) and conveniently being locked or unlocked according to the locking switch (500, 50) pivotal within the first arm (20, 300).

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.

Disclosed are adjustable pliers where the pawl mechanism can be engaged or disengaged to adjust a jaw gap of the pliers. The pawl mechanism can be disengaged either by rotating the handles so as to cause a tab to engage a pocket, and/or by lifting upward on the handles to disengage the pawl teeth from corresponding teeth in a slot of one of the handles. The pliers are therefore advantageous because they do not require a button or lever to adjust the jaw gap, and can therefore be adjusted easily.

Embodiments disclosed herein provide an ergonomic quick release mechanism for hand-held clamping toggle lock tools where a fixed jaw and handle have another jaw movably attached. A moving handle assembly comprises a front handle section and a rear handle section held rigid to one another by a movable release trigger mounted on one of the two sections engaging a catch on the other section. The front handle section connects to the movable jaw and a toggle link. Squeezing the moving handle causes the jaws to close and a toggle pivot to go past toggle over center, locking the jaws. To unlock them, the release trigger is disengaged and the rear handle section is then squeezed causing it to rotate and contact an element of the fixed handle assembly at a release fulcrum point, causing the front handle section to rotate outward, releasing the toggle lock.

A clamp has: a clamping set and a positioning set. The clamping set has a shaft pivotally connected to a first arm and a second arm, and the shaft is provided with an elastic member. The first arm and the second arm are kept open by the elastic member, and the first and second arms are extended downward with a first handle and a second handle. The first handle is provided with a first pin, and the second handle is provided with a second pin. The positioning set is pivoted on a middle section of the first and second handles with the first and second pins. The positioning set is approximately horizontal, and travel distance of the shaft is greatly reduced, which not only reduces the structural cost, but also effectively improves the smoothness of the shaft movement.

A remote operating tool capable of replacing work units contains: a control unit, a connection assembly, and a work unit. The control unit includes a first plier part, a second plier part, and a fixing shaft. The first plier part has a first grip portion and a limitation extension, the second plier part has a second grip portion and an accommodation extension, and the accommodation extension has an aperture. The connection assembly includes a cable and an accommodation sleeve, the cable has a knob, and the accommodation sleeve has a fitting member, wherein the fitting member has a large-diameter section and a small-diameter section. The limitation extension has a first cutout, and the accommodation extension has a second cutout. The control unit further includes a stopper, wherein the defining member is a shell and includes a first chamber.
