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.

A ratcheting pliers device for extracting a fastener from a substrate includes a first arm, which is pivotally engaged to a second arm to define a pair of jaws and a pair of handles. Each jaw has a cutout for insertion of a head of a fastener. A ratchet bar, which is pivotally engaged to the first arm, has a plurality of first teeth extending from its upper surface. A biaser engaged to the first arm and the ratchet bar is positioned to pivot the ratchet bar into engagement with a second tooth that is coupled to the second arm. The second tooth sequentially engages the first teeth as the first arm and the second arm are motivated to a proximate orientation, concurrently with the jaws being motivated to a closed configuration. The jaws are prevented from opening while a user pulls on the handles to extract the fastener.

A hand-held machine tool, in particular a sanding machine, including a rod-type handle element for the user to grip and a processing head which is moveably mounted on the handle element by means of a joint assembly. The processing head has an electric drive motor for driving a tool holder provided for holding a processing tool and a speed-reducing gearbox between the drive motor and the tool holder, the gearbox being designed to achieve a reduction in speed of an output of the drive motor relative to a speed of the tool holder. The drive motor is a brushless motor and a power supply system for the drive motor is arranged at a distance from the drive motor on the handle element, the power supply system being connected to the drive motor by means of a cable arrangement.

Embodiments of the current invention relate to a pliers wrench. Optionally, the jaws of the pair of pliers lock to an adjustable gap size and/or the gap between the jaws is aligned with a rotational axis of the pair of pliers. For example, there may be two jaws that adjust symmetrically around the rotational axis. In some embodiments, each jaw is closed toward an opposing jaw by a lever. Optionally, a locking mechanism locks the jaw when it reaches half the gap width from the rotational axis. Optionally, each jaw is closable independently of the other jaw. Optionally, a notch in the jaws forms an angle for clasping a bolt perpendicular to an axis of the device. For example, the notch may have a 120 angle.

The present invention provides an opening-closing device including a first component, a second component and a third component. The second component is rotatably connected with the first component, and the third component is rotatably connected with the second component. The present invention further includes a mode switching device for switching operating modes of the opening-closing device. The operating modes include a conventional mode and a labor-saving mode. When the opening-closing device is in the conventional mode, the third component is fixed relative to the second component. When the opening-closing device is in the labor-saving mode, the third component is rotated in the opening direction relative to the second component during opening of the opening-closing device, and the third component is rotated in the closing direction relative to the second component during closing of the opening-closing device.
