Abstract (en)

[origin: EP0845331A1] The wrench consists of an elongated outer housing (2) in which the wrench head (1) turns on a pivot (12) and an axially-moving pusher (3) is pressed towards the head by a graduated spring (4). It has a first roller (22) designed to reduce friction between the pusher and the housing and interacting with a flat track (16) inside the housing, and a transmission coupling (13) between the head and pusher. The roller is cylindrical in shape and interacts with a second flat track (20) on the outer surface of the pusher. One of the two tracks has sides which interact with the ends of the roller, while the other one is wider. At the other end of the pusher and on the opposite side there is a second contact member e.g. in the form of a second roller (23) and track (17) similar to the first.
