Abstract: A method and device is disclosed for clamping an object with quick adjusting pliers. A top jaw has a bottom handle, a slot, and a series of ridges located around the slot. A pin extends through the slot and includes an engagement element. A bottom jaw has a top handle and another opening for receiving the pin. The engagement element engages at least one of the series of ridges in a first position, wherein the top jaw and bottom jaw pivot about a first axis that extends through a longitudinal axis of the pin, and wherein the engagement element is moveable along the first axis from the first position to a second position wherein the engagement element does not engage any of the series of ridges.

A pin extends through the slot. A tongue element has a first opening for receiving the pin. A bottom jaw has a top handle and another opening for receiving the pin, wherein the tongue element engages one of the series of ridges, and wherein the top jaw and bottom jaw pivot about a first axis that extends though a longitudinal axis of the pin, and wherein the tongue element is moveable relative to the ridges to allow for engagement or disengagement with said ridges.

Abstract: Clamping or expanding pliers having a first plier arm pivotally connected to a second plier arm, and a toothed structure attached to the first plier arm. A catch member is movably connected to the second plier arm. A single bias spring biases the plier arm apart and biases the catch member to a resting position engaged with the toothed structure. Either with or without the single bias spring the catch member may include an intermediate release position allowing a separating movement of the first and second plier arms without disengaging the catch member from the toothed structure. The first and second plier arms may include a resiliently deformable plastic, with the catch member arranged so that the force required to move it to its release position is lower than the clamping force.

Abstract: The invention relates to pliers having a first operating jaw (1) and a first plier handle (2) fixed thereto, having a second operating jaw (3) which is mounted pivotably by means of a pivot pin (30) and forms a plier mouth with the first operating jaw (1), having a second plier handle (4) which is mounted pivotably on a section (23) of the second operating jaw (3), said section being oriented towards the rear plier end, and having a resilient connecting element (7), of which one end is provided on the second plier handle (4), just behind the second operating jaw (3), and the other end is provided on the first plier handle (2). The pivot pin (30) is fastened on one of the operating jaws (3), and located in the other operating jaw (1) is a slot (33) for accommodating the pivot pin (30), the longitudinal direction of said slot running in the plier plane, at least more or less perpendicularly to the longitudinal direction of the pliers.

Abstract: Self-adjusting pliers including first and second members each handle portions and jaw portions. The first member defines a rack having a plurality of teeth. A rack engagement structure is mounted to an intermediate portion of the second member and positioned adjacent the rack. During initial manual movement of the handle portions towards one another, the rack engagement structure travels in disengaged, spaced relation with respect to the rack. Then, after the jaw portions engage opposing sides of a workpiece, continued movement of the handle portions towards one another causes movement of the rack engagement structure toward the rack until the rack engagement structure engages the rack. The rack engagement structure has a movement restrictive portion being cooperable with the rack so as to limit the movement of the rack engagement structure toward the rack when the jaw portions contact one another in the absence of a workpiece therebetween.

Abstract: A pliers with adjustable jaws permits alignment of the jaws in various orientations with respect to the handles. The pliers includes an internal spring which maintains the jaws normally in the open position. Detent balls, in combination with the spring enable movement of the jaws simultaneously and equally between detent positions to adjust the orientation of the jaws with respect to the handles.

Abstract: A plier-like tool having links added between the jaws and the body of the pliers. The links not only extend the length of the jaw side of the pliers, but also pivot relative to each other and perpendicular to the opening and closing direction of the pliers. The screws in these links can be left untightened to permit the links to pivot allowing the jaws to gain access into restricted areas otherwise inaccessible. Even with the link-screws loose the gripping force is transferred through the links to the jaws enabling the user to still grip objects or even retrieve them by simply pulling the pliers back out and letting the links follow. An additional aspect to the flex-link pliers is that the link-screws can be tightened so the links maintain their position relative to each other so the user can create any shape pliers desired.
