Abstract (en)
[origin: WO2019006563A1] The invention concerns a torque tightening device (10) comprising a gripping handle (11), an axial rod (12) associated with said gripping handle (11) and arranged to carry a tightening tool (13) and containing a rigid body (14). A peripheral ring (23) mounted on a fluted tube (16) has, on the outer surface of same, a spiral thread (24), onto which there is threaded an end tip (25) of the body (14), in the form of an externally threaded bushing, the thread (26) of which is complementary to said thread (24) engaged with same. The peripheral ring (23) is linked to the fluted tube (16) and the end tip (25) is linked to the body (14). The two threads (24 and 26) link the two elements (23 and 25), and therefore the fluted tube (16) and the body (14). Rotating the body (14) causes the fluted tube (16) to move in a linear manner. In practice, each "click" of the mechanism moves the fluted tube, for example, a fraction of a turn, and causes the two elements (23 and 25) to move axially relative to each other, in order to disconnect the gripping handle (11) and the axial rod (12).
