Spanner for use as hand tool for e.g. tightening fastening screws of wheel of car, has strand conferring flexibility on handle for connection or separation of handle, where connection or separation constitutes visual indication of torque

摘要

The spanner (1) has a handle (2) connected to a screwing arm (5), where a screwing casing (6) is arranged at a free end of the screwing arm. An intermediate strand (4a) is inserted between the handle and the screwing arm, and the handle extends above or below the screwing arm. The intermediate strand confers flexibility on the handle for connection or separation of the handle relative to the screwing arm, where the connection or separation of the handle constitutes visual indication of applied tightening torque. A folding elbow (3a) connects the handle to the intermediate strand.
