A pivoting pliers jaw (18) having a design including plates for manually actuated crimping pliers (1). The pivoting pliers jaw (18) which includes a supporting plate (23) at which on both sides pliers jaw plates (25) are held. The pliers jaw plates (25) form an accommodation for a die insert or support the accommodation. According to the invention the pivoting pliers jaw (18) is L-shaped. Bolts (27, 28) for mounting the pliers jaw plates (25) to the supporting plate (23) are arranged in a way such that a connecting axis of the longitudinal axes of the bolts (27, 28) have an orientation approximately perpendicular to a supporting plane (36) for the effective crimping force.

Pliers are provided. Pliers include an upper handle, a lower handle, an upper jaw coupled to the upper handle, and a lower jaw coupled to the lower handle. In general, the upper jaw includes workpiece engagement surface, such a first set of teeth configured to engage a workpiece, and the lower jaw includes a workpiece engagement surface, such as a second set of teeth and a third set of teeth. The lower jaw opposes the upper jaw such that the first set of teeth faces the second set of teeth and the third set of teeth. At least a section of the workpiece engagement surface of the lower jaw is movably coupled to the lower jaw such that it moves relative to the lower as torque is applied to a workpiece, thereby increasing torque applied to the workpiece.

An auxiliary tool to be detachably attached to tip portions (36, 46) of a pair of arms (30, 40) which are opened/closed by each rotating relative to a base (24) of an actuation device (e.g., hydraulic actuation device (10)), includes a first auxiliary member (60) to be detachably attached to a first arm (30) of the pair of arms (30, 40), the first auxiliary member (60) having at least one claw portion (62), and a second auxiliary member (70) to be detachably attached to a second arm (40) of the pair of arms (30, 40), the second auxiliary member (70) having at least one claw portion (72). Positions of the claw portion (62) of the first auxiliary member (60) and the claw portion (72) of the second auxiliary member (70) are such positions that the claw portion (62) of the first auxiliary member (60) and the claw portion (72) of the second auxiliary member (70) do not come into contact with each other even when the arms (30, 40) are closed in a state in which the first auxiliary member (60) is attached to the first arm (30) and the second auxiliary member (70) is attached to the second arm (40).

A locking pliers includes a pliers-body, a rotating shaft and an operating and pivoting unit. The pliers-body includes a fixed jaw, a movable jaw and a jaw end member disposed on the movable jaw. The rotating shaft is rotatably connected with the fixed jaw about a pivot axis and is movable along the pivot axis, and has clamp and insert ends. A clamp member is disposed on the clamp end. A pivot member extends through the fixed jaw and connected with the rotating shaft and is operable to move the rotating shaft close to or away from the fixed jaw. A retaining member extends through the fixed jaw and the rotating shaft to retain the rotating shaft to a first or second position. With the rotating shaft rotated between first and second positions, the locking pliers can be shifted to two types of use.

The present invention relates to a manual hydraulic multi-functional extra-high-voltage insulating gear gripper pliers stick for live-wire work and the pliers stick and, more specifically, to a manual hydraulic multi-functional extra-high-voltage insulating gear gripper pliers stick for live-wire work and an indirect live-wire construction method using the pliers stick, which: allow components or the like, which are installed on and removed from an electric pole in order to perform electric wire-stringing work or fix electric wires, to be remotely constructed by means of the indirect live-wire work while maintaining a safe distance from live wires when constructing power distribution equipment in an extra-high-voltage live-wire state; ensure safety by eliminating risks due to instability during work, said instability occurring due to the intensity of the labor and the physical limitations of the workers; and bring about improvements in utilization efficiency.

A hand tool includes a handle assembly, a jaw assembly, a locking assembly, and an adjustment assembly. The handle assembly may include a first handle and a second handle, each of the first and second handles having a proximal end and a distal end. The jaw assembly may include a first jaw and a second jaw. The first jaw may be attached to the proximal end the second handle via a transition region comprising an adjustment channel. The locking assembly may be configured to enable the first and second jaws to be locked at a selected distance from each other in a locked state. The adjustment assembly may include the adjustment channel and a bite adjustment member configured to enable the selected distance to be modified in an unlocked state based on a position of the bite adjustment member in the adjustment channel.
