A hand tool includes a handle section, a working end operably coupled to the handle section, and a jaw assembly disposed at the working end. The jaw assembly includes a movable jaw and a fixed jaw. A span defined between the movable jaw and the fixed jaw is adjustable. Each of the movable jaw and the fixed jaw includes an array of teeth defined by ridges that extend substantially parallel to each other. The array of teeth on each of the fixed jaw and the movable jaw includes a first set of teeth having a first width and a first depth, and a second set of teeth having a second width and a second depth. The first depth is less than the second depth and the first width is less than the second width.

A hand tool includes a handle assembly, a jaw assembly, a locking assembly, and an adjustment assembly. The handle assembly may include a first handle and a second handle, each of the first and second handles having a proximal end and a distal end. The jaw assembly may include a first jaw and a second jaw. The first jaw may be attached to the proximal end the second handle via a transition region comprising an adjustment channel. The locking assembly may be configured to enable the first and second jaws to be locked at a selected distance from each other in a locked state. The adjustment assembly may include the adjustment channel and a bite adjustment member configured to enable the selected distance to be modified in an unlocked state based on a position of the bite adjustment member in the adjustment channel.

A tool jaw width adjustment structure includes a first plier body and a second plier body that cross each other. The first plier body has an elongated hole. One side of the elongated hole is provided with a toothed portion. The second plier body is provided with a shaft inserting through the elongated hole. A distal end of the shaft is provided with a side plate extending beyond one side of the toothed portion. The shaft is provided with a toothed block meshing with the toothed portion. When the second plier body is opened relative to the first plier body, the shaft is driven to move from a first position to a second position in the elongated hole, so as to increase a width between jaws of the first and second plier body.

A hand tool has a pivot connection pivotally attaching a first arm to a second arm, with the pivot connection fixed relative to the first arm and movable to first and second positions relative to the second arm. A spring urges the pivot connection into the first position. When jaws on the front ends of the arms clamp tissue with force greater than a pre-set threshold, the spring force is overcome and the jaws may move linearly apart, allowing for more uniform clamping of the tissue. The first arm may have an arm spring extending between a front segment pivotally attached to a rear segment of the first arm.

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.

Various embodiments of pliers and pipe wrenches are provided. Wire cutters enable a finger pivot hole to enhance the grasp of the wire cutters while rotating the tool and/or stripping wire. Pipe wrenches include different configurations of teeth to improve durability and grip on a workpiece. Pliers are provided with axial teeth to enhance gripping a workpiece in different directions. Pliers are provided with selectable mechanical advantages so that a user may select the mechanical advantage desirable for a particular application.

A pipe expanding plier is disclosed, and it includes a fixed handle, a movable handle, a mounting base, a pipe expanding head, and a pushing cone. One end of the pushing cone is provided with a rotating shaft, which is connected with the movable handle through a block. The mounting base is provided with a cavity. A gear ring, a gear ring shell and a shell reset element are provided in the cavity, and the gear ring is connected to the rotating shaft, and the gear ring is located in the gear ring shell, and a pawl assembly is provided in the gear ring shell, a reset block and a linkage block are provided on the gear ring shell, the shell reset element is arranged between the reset block and an inner wall of the cavity, and the linkage block extends out of the cavity to be matched with the movable handle.
