The invention relates to pressing tongs or crimping pliers (1). The pressing tongs or crimping pliers (1) comprise a fixed pliers jaw (4) and a movable pliers jaw (6). A closing motion of the movable pliers jaw (6) can be initiated by pivoting a movable hand lever (9) via a toggle lever drive (11).

According to the invention, a further lever (48), especially in the form of an additional hand lever (49), is provided. The further lever (48) is coupled to the movable pliers jaw (6) in such a way that when the further lever (48) is pivoted, an opening motion of the pliers jaw (6) into an insertion and/or removal position can be initiated.

A combination clamp and wrench tool includes a main body, a fixed jaw attached the main body, and a floating clamp mechanism. The floating clamp mechanism may include an adjustable jaw. The floating clamp mechanism may be attached to the main body such that the floating clamp mechanism is slidable relative to the main body towards and away from the fixed jaw. The worm gear and the rack are attached to the floating clamp mechanism. Actuation of the worm gear moves the rack linearly relative to the floating clamp mechanism. When the rack is moved to contact the fixed jaw, the combination clamp and wrench tool operates in a wrench mode, and when the rack is moved away from the fixed jaw, the combination clamp and wrench tool operates in a clamp mode.

Embodiments disclosed herein provide an ergonomic quick release mechanism for hand-held clamping toggle lock tools where a fixed jaw and handle have another jaw movably attached. A moving handle assembly comprises a front handle section and a rear handle section held rigid to one another by a movable release trigger mounted on one of the two sections engaging a catch on the other section. The front handle section connects to the movable jaw and a toggle link. Squeezing the moving handle causes the jaws to close and a toggle pivot to go past toggle over center, locking the jaws. To unlock them, the release trigger is disengaged and the rear handle section is then squeezed causing it to rotate and contact an element of the fixed handle assembly at a release fulcrum point, causing the front handle section to rotate outward, releasing the toggle lock.

One or more clamping aid tools for mounting to various squares and straight edges, including carpenter squares, framing squares, speed squares or the like, and various straight edges and rulers for easily and accurately positioning various objects, either flat and/or round, magnetic or not. The clamping aid tools can secure these squares and straight edges to various objects while they are being fitted, secured and/or welded together.

Disclosed is a handheld canvas stretching tool used to stretch canvas across a stretcher frame. The tool can include upper and lower jaw plates with slip resistant surfaces configured to firmly grasp a portion of the canvas to be stretched. The tool includes wide locking pliers technology, and a second class lever action. These features give the user the mechanical advantage needed to apply a taut stretch to the canvas, while permitting one hand, and sometimes both hands, of the user to be free to apply staples that secure the canvas to the stretcher frame.

A hand tool includes a handle assembly, a jaw assembly, and an adjustment assembly. The handle assembly may include a top handle and a bottom handle. The jaw assembly may include a top jaw and a bottom jaw. The top and bottom jaws may be operably coupled to the top and bottom handles to compress the top and bottom jaws toward each other responsive to compression of the top and bottom handles toward each other. The adjustment assembly may be configured to enable a grip size defined by the jaw assembly to be modified and includes a first adjuster disposed at a distal end of the top handle, a second adjuster disposed at a point between a middle portion and proximal end of the top handle, and an adjustment rod operably coupled to each of the first and second adjusters.

A hand tool includes a handle assembly, a jaw assembly, a clamping assembly, and an adjustment assembly. The handle assembly includes a first handle and a second handle that each include a proximal end and a distal end. The jaw assembly includes a first jaw and a second jaw. The jaw assembly is operably coupled to the proximal end of the first and second handles. The clamping assembly may be configured to enable the first and second jaws to be locked at a selected distance from each other in a locked position. The adjustment assembly may be configured to enable the selected distance to be modified. The adjustment assembly may be disposed between the first and second handles.

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.

A clamping device includes a fixing clamp and a positioning clamp for clamping two plate pieces. The positioning clamp includes a main body having a first abutment surface and a second abutment surface separated by an abutment angle and suitable for respectively abutting against first plate surfaces of the plate pieces. A reversing mechanism includes a reversing member rotatably disposed in the main body and having a limiting portion. The reversing member is rotatable relative to the main body between a first side and a second side, in which the limiting portion is aligned with the first abutment surface and the second abutment surface, respectively, and is suitable for abutting against the end surfaces of the plate pieces.

Presented here is a pole clamp that can be operated by a single hand, and which can clamp onto objects of various sizes and shapes. The clamp can be operated using a handle which, when pushed in an opening direction opposite a base member, opens the jaws on the clamp. The motion of the handle can adjust the opening of the jaws. In addition, the opening of the jaws can be adjusted using a thumb dial which can shorten and lengthen a locking member, which in turn adjusts the opening of the jaws. The clamp can lock onto the object when the handle is pushed in a direction opposite the opening direction, past the dead center point, and the locking member prevents further movement of the handle.
