A device comprising: (a) a first working arm; (b) a shuttle located on the first working arm, and (c) a bias device; wherein the bias device biases the first working arm when the shuttle is in a first position, and wherein the bias device is free of biasing the first working arm when the shuttle is in a second position.

A pair of pliers having two pliers legs that are arranged in a crossing manner, wherein a fixed joint is formed, having a joint pin. The joint pin has a first conical portion that widens towards the outer side, wherein, the pliers leg is assigned a second conical portion which bears on the first conical portion and transitions into a first mouth portion that leads into the outer side of the pliers leg. The joint pin has a second mouth portion which, starting from the outer side of the pliers leg and perpendicularly to a joint axis, overlaps the first mouth portion. The first and second mouth portion, bound a circular clearance between one another, the radial dimension of the clearance corresponding to 0.05 to 0.15 times the radial dimension, measured from the joint axis of the joint pin in the region of the second mouth portion.

A tool for crimping, pressing or deforming a workpiece includes a first grip element having a first grip portion; a second grip element having a second grip portion; a mechanism housing, which is arranged on the first grip element and has an end surface facing away from the first grip portion; a tool mechanism, which is enclosed by the mechanism housing and can be actuated to crimp, press or deform the workpiece by adjusting the first and second grip elements relative to one another; and an impact protection element, which is arranged on the first grip demerit and has two limbs and an end face portion, which interconnects the limbs. The mechanism housing is arranged between the limbs, and the end face portion extends beyond the end surface of the mechanism housing.

The invention relates to a manually actuated hand tool (2) which might e.g. be embodied as pliers (1). According to the invention, the hand tool (2) comprises a display device (13) by which it is possible to display a hand tool identification (16). It is possible to electrically modify the displayed hand tool identification (16). It is possible to permanently display the hand tool identification (16) without electric powering. Preferably, for this purpose the display device (13) comprises a so-called electronic paper.

A disposable modular patella protector and clamp is disclosed, providing the ability for a surgeon to shift the procedure sequence of the implantation of the patella from the end of a total knee replacement procedure to anytime during the procedure by providing a modular clamp that holds and protects the patella prosthesis and prepared patella. The clamp may be positioned in a manner in which it does not obstruct the patella or the prosthesis, allowing the surgeon to attend to other elements of the procedure while the bone cement is allowed to cure.

The present invention provides a hand tool for enabling an individual to change the height of a traffic intersection light. The hand tool comprises a pair of elongated members with a handle end, jaw end, and a pivot joint, whereby the elongated members are hingedly connected. One jaw member has a distal curved pointed end and the other jaw member has an upper flat end. In use, the curved pointed jaw member is inserted into a height adjuster device to unlock it from a cable. Once unlocked, a technician can selectively reposition an attached traffic intersection light. The hand tool keeps the height adjuster device unlocked because the jaws are spring biased away from each other. Overall, the device that can assist with altering the height of a traffic light.
