<p>The screwing tool comprises a body (2) in which a motor driven shaft (3) is guided. The body is terminated by an angular socket (10) in which a shaft (7) is guided. An angled pinion (6), wedged on this shaft, meshes with an angled pinion (5) wedged on the motor driven shaft. The shaft has a coupling (11) connecting it to the tool drive (21) supported laterally by a casing (18) fixed to the corresponding end of the socket. The socket rotates a collar (15), with a retaining stop (14), having an internal thread (16). The casing has an external thread (34) engaging with the collar thread. The collar has angularly displaced notches (17) and the casing has projections (36) which selectively engage in these notches.</p> |
