Pliers comprising a head portion incorporating gripping faces within the opposing jaws for the clamping of the desired workpiece, pivotal handle portions and a sprung toothed link positioned between the handles. Bow shaped resilient portion or portions are usefully incorporated within either or both the jaw or handle portions, when the pliers are operated these resilient portions impart a useful superior sprung pressure upon the clamped workpiece by the gripping face of the jaws. The Jaws and bend promoting portion are contiguous with each individual handle and gripping portion. The jaws can further be usefully locked in the required clamping position upon the workpiece by a toothed sprung strut pivotally attached to the fixed handle and conveniently being locked or unlocked according to the locking switch pivotal within the opposing moving handle.

A hand tool and a wire stripper. The hand tool may include a first jaw portion and a second jaw portion having a spring constant more than about 2,225 lbs./in., measured when a force is applied in a direction parallel to the pivot axis to an associated jaw tip with a pivot member being held. The hand tool may include a jaw portion having a gripping surface and an angled wall connected to a side wall and defining a wire stripping portion, the wire stripping portion including a cutting edge and a recess defined in the angled wall, the recess extending from the cutting edge to an end at the one of the side walls, the angled wall being arranged non-parallel to the gripping surface and non-perpendicular to the side wall. The wire stripper may be a forged wire stripper including jaws defining a stripping aperture for Romex® NM wire.

Disclosed are a ceramic tile leveling bracket, pushing and clamping pliers and a ceramic tile leveling and laying system. The ceramic tile leveling and laying system comprises: a ceramic tile leveling bracket (1), an insertion block (2) and pushing and clamping pliers (3), wherein the ceramic tile leveling bracket (1) is provided at the junction between two adjacent ceramic tiles (4), one end of the insertion block (2) is inserted into an insertion block through hole (16) of the ceramic tile leveling bracket (1), and the pushing and clamping pliers (3) push and clamp the insertion block (2) into the insertion block through hole (16), so that an insertion block bottom surface (21) is tangent to upper surfaces of the two ceramic tiles (4). The ceramic tile leveling and laying system is easy to operate, and helps to improve the laying efficiency and laying quality.

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.

A hand tool structure has two plier bodies pivoted by a pivot member, and a knob mechanism for controlling opening and closing of the two plier bodies. The pivot member includes a cylindrical body pivoted to the two plier bodies and a spring sleeved onto the cylindrical body and having two ends abutting against the two plier bodies. Opposing sides of the two plier bodies each include a V- shaped groove to form a square clamping hole when the two plier bodies are closed; a row of teeth; a first cutting portion for cutting an electric wire or cable; a second cutting portion for cutting a metal wire; a wavy peeling portion for peeling a jacket of the electric wire, the peeling portion including curved sections each having a different radius of curvature, wherein when the two plier bodies are closed, the curved sections form receiving holes with different diameters.

An opening structure of a tool grip includes a left grip and a right grip that are intersected and pivoted. An elastic connecting strap is provided between the left and right grips. The left grip has at least two left studs. The right grip has at least two right studs. The connecting strap has a length greater than a distance between the left and right grips. One end of the connecting strap has at least two left recessed portions for engagement of the left studs. Another end of the connecting strap has at least two right recessed portions for engagement of the right studs. By selecting the position where the left recessed portions are engaged with the left studs and the position where the right recessed portions are engaged with the right studs, a force that the connecting strap pushes against the left and right grips to open is adjustable.

A plier tool is described that can be used for removing connections or connectors in area that is difficult to get too because of the connection or connector mounted position. The tool will be used to position its gripping heads in different angles relative to its arms.
