Abstract
The invention concerns a device comprising a screw () with pitch (P) driven by a motor (M), a nut () co-operating with the screw () and designed to be driven in translation in the direction of the screw axis, said nut being integral in translation with a member (), guide means (L,L) defining a linear guiding to lock the rotation of the nut in a first phase of displacement, second guide means (H,H) defining a helical guiding having a reverse pitch (P) relative to the pitch of the screw to enable the transverse pitch and hence the translational speed of the nut to be decreased in said second phase of displacement. The inventive device can be used to produce a relative displacement between the members (and) of a clamping tool.
