Abstract
In an arrangement for displacement of a displacement member along a stationary base by means of a reciprocatable elongate actuating member, the displacement member has at least one linear tooth arrangement. Two axially spaced ratchet members are pivotably mounted on the actuating member at at least one longitudinal edge thereof. The ratchet members diverge away from each other and have ratchet teeth which are operable to engage with the linear tooth arrangement. The ratchet members are urged towards the linear tooth arrangement by springs. Operatively disposed between the at least one linear tooth arrangement and the actuating member, for disengagement of the corresponding ratchet member out of the linear tooth arrangement, is a disengagement member determining the linear stepping advance movement performed by the displacement member.
