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.

A hand tool has first and second tool legs that are connected in a pivot region and which overlap in an overlapping region both in an open state of the hand tool and in a closed state of the hand tool. The tool legs interact with a spring such that the tool legs can be pivoted, even beyond a basic open position, into an extended open position by the user in applying manual force against the force of the spring, the spring coming into action in the case of the additional pivot movement of the hand tool legs beyond the basic open position and/or in the case of a closing pivoting movement of the hand tool legs acts on different bearing surfaces of the hand tool legs.

The present disclosure provides self-adaptive laborsaving crimping pliers including a long handle, a movable handle, and a pliers head arranged on one end of the long handle and the movable handle. The long handle is bifurcated to form connecting arms rotatably arranged on the pliers head and elastic support arms. The connecting arms forms a linkage between the long handle and the pliers head. The movable handle is bifurcated to form movable connecting arms and elastic driving arms. The movable connecting arms are rotatably arranged on the pliers head and forms a linkage between the movable handle and the pliers head. The elastic driving arms are rotatably arranged on the elastic support arms to make the movable handle rotatably connect with the long handle. Limiting portions are arranged on the elastic support arms. A tension spring is arranged between the limiting portions and the movable handle.

A plier and jaw modifier body for use with a plier. The plier has a pair of opposing jaws. There is a jaw modifier body coupled to each of the opposing jaws via at least one coupler. The coupler can be a screw, bolt, or the like, or it can be a magnet. Each jaw modifier body has at least one working surface to engage a work piece. The jaw modifier body can be coupled and decoupled to the plier jaws to provide customization and versatility to pliers. Various working surfaces can be utilized to hold and manipulate various work pieces.

A press cutting tool is disclosed. The press cutting tool includes a first and second plier, a first and second connecting rod, an opening, a pressing block, and a cutting block. The first and second connecting rods are connected to the second plier. The opening is used for placing a connection head. The pressing block is connected to the first connecting rod for clamping housing. The cutting block is connected to the second connecting rod for cutting the connection line; wherein the pressing block and the cutting block slide separately, and an initial distance from the pressing block to the opening is greater than an initial distance from the cutting block to the opening. After the first and second plier are pressed, the pressing block slides first to clamp and press the housing, and then the cutting block slides to cut the connection line.
