    Abstract: 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.

    Abstract: The present invention relates to a hand tool. More specifically, a rapid adjust multigrip tool having a first arm, second arm, linking mechanism and locking mechanism. The first arm is connected to the second arm via a primary pivot. The linking mechanism biases the arms away from one another. The locking mechanism allows an operator to selectively secure the first and second arms together.

    Abstract: A hand tool includes a first jaw, a first handle fixed to the first jaw, a second jaw, and a second handle pivotally coupled to the second jaw, a link member, and an adjustment member. The adjustment member is operable to axially move a first end of the link member to vary a distance between the first and second jaws. The adjustment member includes an engagement surface engageable with the first end of the link member, a shank in threaded engagement with a bore in the first handle, and a flange extending from the shank opposite the engagement portion. The flange includes a first side, a second side opposite the first side, and an elongate opening extending through the first and second sides.

    Abstract: A safety structure for pliers contains: a fixed clamp jaw, a movable clamp jaw, a first handle, a second handle, an actuation unit, and an adjustment screw. The fixed clamp jaw is disposed on the first handle, and the movable clamp jaw is rotatably connected with the fixed clamp jaw and the second handle. The actuation unit includes a spring mounted on the first handle and between two rotatable connecting portions of the movable clamp jaw, and the actuation unit also includes a driving post rotatably connected the second handle and inserted into the first handle. The actuation unit further includes a threaded post having an arcuate section and includes a pushing post rotatably joined with the second handle and forced by the arcuate section. The driving post has a push portion, and the adjustment screw is screwed into the second handle and abuts against the push portion.

    Abstract: The present invention provides a pair of locking pliers, comprising a main clamp body, a movable jaw, a movable handle, a link, a wedge-shaped piece and an adjusting mechanism. When the jaw span reaches maximum, the pair of locking pliers satisfies the following relations: H/D1≧0.5, (D2+D3)/D1≦3.1, D2/D3≧0.45, wherein H is the distance between the center of the first pivot and the axis X of the fixed handle passed through the center of the fourth pivot, D1 is the distance between the center of the first pivot and the center of the second pivot, D2 is the distance between the center of the second pivot and the center of the third pivot, D3 is the distance between the center of the third pivot and the center of the fourth pivot. The maximum opening angle of the jaw span of the invention can reach 49°, which results in the fact that the pair of locking pliers can efficiently and conveniently clamp large-size working piece. The clamping force can he adjusted and has nothing to do with the clamped working piece, which is beneficial to clamp the working pieces with different sizes. In addition, when the jaw span reaches the maximum, the angle between the movable handle and the fixed handle is relatively small, which is convenient for operating the pair of locking pliers with single hand.

    Abstract: A self-adjusting clamp system having an upper clamp arm connected to an upper handle and a lower clamp arm connected to a lower handle. The lower handle includes a hollow interior that defines an axis of reciprocation. A wedge lock and activator wedge are positioned within the hollow interior and separated by a separation plate. As the upper handle and lower handle are opened and closed, the wedge lock and activator wedge slide within the hollow interior of the lower handle along the axis of reciprocation as the separation plate slides vertically within a slot in the lower handle. The wedge lock, separation plate and activator wedge work in cooperation with one another to lock and unlock the clamp arms on workpieces of various widths automatically and without user-applied adjustments.
