A retrofittable auxiliary pliers handle assembly includes a coupler removably coupled to a grip of a pair of pliers. The coupler is positionable between a free end of the grip and a pivot of the pliers. The coupler includes a receiver positioned laterally away from an exterior lateral surface of the grip. An auxiliary handle is positioned in the receiver such that the auxiliary handle is positioned adjacent to the exterior lateral surface and extends away from the pivot. A finger space is defined between the auxiliary handle and the grip. The auxiliary handle comprises a plate that elongated and has a first end, a second end, a first lateral side, a second lateral side, an upper edge and a lower edge. The coupler engages the plate adjacent to the first end such that the first lateral side faces the exterior lateral surface.

A pair of locking pliers with an indicatable adjustment device includes a main body which includes a first and a second gripping jaw cooperatively for clamping a workpiece and an indicatory adjustment device configured to fine tune the clamping pressure between the first and the second gripping jaws and having an auxiliary sign which shows different indications in response to the operation of the adjustment device.

The present invention relates to an open-close handheld apparatus and a method of adjustment of the angle between the handheld portions thereof. The open-close handheld apparatus includes a first member and a second member. The first member includes a first clamping portion and a first handheld portion. The second member includes a second clamping portion and a second handheld portion. The first clamping portion and the second clamping portion are rotatably and movably connected via a first axle pin. The first clamping portion and the second clamping portion open and close relative to each other, the plane in which the open-close path thereof is located is an open-close plane. The first handheld portion is rotatably connected to the first clamping portion. The plane in which the rotation path of the first handheld portion is located is the same as or parallel to the open-close plane. A locking arrangement is provided at the joint between the first handheld portion and the first clamping portion, used for locking or unlocking the first handheld portion and the first clamping portion.

A hand tool (1) comprising a first handle (2) and a second handle (3), which are pivotally arranged with respect to each other, a first jaw (4) that is fixed to said first handle (2), the first jaw (4) comprising a first crimp portion (6), and a second jaw (5) comprising a second crimp portion (7), wherein the first and second crimp portions (6,7) are arranged to be moved towards each other by actuation of the first and a second handle (2,3), so as to close a crimp opening (8) formed between said first and second crimp portions (6,7). The second jaw (5) is pivotally arranged with respect to the first handle (2) around a first pivot point (10), and with respect to the second handle (3) around a second pivot point (11) arranged at an upper end of said second handle (3), wherein the first handle (2) comprises a first resilient portion (12) between the first crimp portion (6) and the first pivot point (10), allowing the first crimp portion (6) to flex with respect to the first pivot point (10).

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 method of manipulating a wire, having an electrical contact, comprises clamping the wire with a predetermined force between a first gripping portion, installed in a first channel of a first tip half, and a second gripping portion, installed in a second channel of a second tip half. The method also includes pushing the electrical contact into a receptacle of a terminal block using a first internal shoulder of the first channel and a second internal shoulder of the second channel to interlock the electrical contact and the terminal block. With the wire clamped between the first gripping portion and the second gripping portion, the method includes verifying that the electrical contact and the terminal block are interlocked by pulling the first tip half and the second tip half away from the terminal block until the wire slips along the first gripping portion and the second gripping portion.
