The invention deals with a holder (22, 23) for holding a replaceable part (1) of a tool, such as a replaceable jaw of pliers, wherein the replaceable part (1) comprises a first locking member (6), and wherein the tool further comprises a handle (3) comprising a second locking member (8), wherein one of the first and second locking members (6, 8) is moveable relative to the other locking member between: an engaged position wherein the second locking member (8) is engaged with the first locking member (6) so as to lock the replaceable part (1) to the handle (3), and a disengaged position wherein the second locking member (8) is disengaged from the first locking member (6) so as to allow the replaceable part (1) and the handle (3) to be separated, wherein the holder (22, 23) comprises a cavity (32) for receiving the replaceable part (1), and an unlocking member (36) adapted to move said one of the first and second locking members (6, 8) from the engaged position to the disengaged position when the replaceable part (1) is received in the cavity (32).

A pliers-valve-wheel combination tool for safe and efficient working upon systems and equipment having large wheeled valves, from a ladder, lift, or platform, often with only one hand free, providing adjustable pliers for performing various maintenance tasks and a valve-wheel wrench for quickly, efficiently, and safely manipulating valves in both expected and unexpected circumstances, without a cumbersome change of tools.

The invention relates to manual pliers of different types and/or geometries. According to the invention, the manual pliers have a modular design. Here, without any adaptations of the design a base module (41) can be combined with different pliers head modules (38a, 38b, 38c).

By the inventive modular design it is possible to reduce the manufacturing costs and to use a large number of same parts for manufacturing manual pliers of different types.

A plier wrench is provided and includes a jaw that can be disengaged from the remainder of the wrench and reengaged with the remainder of the wrench while the remainder of the wrench remains in its fully assembled condition. In one form, the jaw is reversible and includes two different jaw surfaces that can be selectively utilized depending upon the type of workpiece that will be engaged by the plier wrench.

An electrosurgical device kit includes an elongate first member, an elongate second member disposed adjacent to the first member, the second member being at least movably coupled to the first member, a first electrode head removably attachable to the first member, a second electrode head removably attachable to the first member, and a third electrode head coupled to the second member. The first, second, and third electrode heads are configured to apply a current to a tissue, the first and second electrode heads being non-identical.

A pair of universal pliers includes a fixed structure, a movable structure movably connected to the fixed structure and including front and rear movable handle plates, and a quick release mechanism including a trigger and a resilient locking subunit. The resilient locking subunit includes a movable pin inserted through and slidable along a first guide slot of the front movable handle plate and a second guide slot of the rear movable handle plate. The resilient locking subunit is switchable between a locked state where the rear movable handle plate cannot pivot relative to the front movable handle plate and a non-locked state where the rear movable handle plate can pivot relative to the front movable handle plate.
