摘要

Wrench comprises two parts (1, 2) which are joined together and rotate about a common geometric axis (O). The working part of the wrench is a circle having two projections (C, D) arranged diametrically opposite each other and rotated by an angle (E) of between 0 and 45 deg from the relative longitudinal axis of the wrench.
