Abstract

The invention provides a retention mechanism (1) for retaining a workpiece in a rest position. The mechanism comprises at least two permanent magnets (8) positioned about the proximal end of the workpiece (2) and a ferromagnetic zone (10) at at least the proximal end of the workpiece. The at least two permanent magnets are of the rare earth type and the magnets are radially positioned with respect to an axis of the workpiece with the opposed poles being of opposite polarity. The invention also relates to a device including the mechanism.
