Pliers having two arms which cross at a pivot bolt, one of which being movable and the other being stationary, with grip sections being formed on one side of the pivot bolt, and interacting jaws being formed as the beak on the other side of the pivot bolt. The stationary arm further has a longitudinal slot with teeth, and the pivot bolt, which is located in a receptacle, is movable about the longitudinal axis thereof, counter to the force of a spring, out of engagement with the teeth into a release position and being held in the direction of the longitudinal axis with the aid of a blocking projection, which interacts with a blocking part in the receptacle. The blocking projection and the blocking part are designed to run over each other during assembly, overcoming the effect of the spring.

Dual-mode adjustable pliers include a first handle member including a first handle and a first jaw and a second handle member including a second handle and a second jaw. The pliers may also include a channel disposed in the first handle member and an adjustable pivot affixed to the second handle member and disposed within the channel. The pliers may also include a movable mode selector member. In an engaged position, the mode selector member is engaged with both the first handle member and the second handle member, and, as the second handle is moved towards the first handle, the adjustable pivot moves within the channel. In a disengaged position, the mode selector member is not engaged with both the first handle member and the second handle member, and, as the second handle is moved towards the first handle, the adjustable pivot maintains a position within the channel.

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.

Pliers with adjustable angle include a handheld portion, a grip portion, and an angle adjustment device. The handheld portion includes a first handle and a second handle. The grip portion is pivotally disposed on the handheld portion and includes a first jaw and a second jaw. The angle adjustment device is disposed between the handheld portion and the grip portion. The angle adjustment device optionally refrains the grip portion from rotating with respect to the handheld portion, or allows the first jaw and the second jaw to pivot with respect to the handheld portion for adjusting the angle.

Tool including a pivot and a handle provided on one side of the pivot. The handle includes a first handle and a second handle. Jaws are provided on another side of the pivot, and the jaws include a first jaw and a second jaw. A first joint is provided in the first jaw. The first jaw includes a base provided between the first joint and the handle.

The present invention discloses a pair of adjustable pliers, comprising a first handle and a second handle, both of which have a gripping part arranged at a front end thereof, the two gripping parts forming a jaw span, the first handle and the second handle being arranged in an intersectional manner and relatively fixed via a connecting mechanism, wherein the second handle has an elongated rack slot at a position of the connecting mechanism, and the rack slot is provided with a toothed rack on an inner side part thereof. The connecting mechanism comprises a positioning snap piece arranged inside the rack slot and a link mechanism connected with the positioning snap piece, the positioning snap piece has lateral teeth which are engaged with the toothed rack on the rack slot, the link mechanism is provided to drive the positioning snap piece to rotate and disengage the lateral teeth on the positioning snap piece from the toothed rack. Thus the first handle can move relative to the second handle along the rack slot through the movement of the connecting mechanism. The link mechanism comprises a trigger shaft connected with the positioning snap piece, and the trigger shaft has a trigger part thereon. The present invention has the advantages that the right handle can be directly pushed to achieve the quick one-way adjustment, which is convenient and saves effort compared to the ordinary water pump pliers that need two-handed adjustment.
