<p>The securing arrangement for a workpiece jig, has a hat-shaped boss support (10) with a flush central boss (14). The boss fits in the bore (18) of a bush, which is simultaneously housed inside the support up to its stop face (17). On the inside, the support widens its mouth (25), and/or the bush tapers on the outside towards its own axial end stop face (27). The boss can extend as far as where the support starts to widen, and it can also have a taper (32) on the outside of its free end, working with a mating bell-mouthed portion of the bush (33), but which extends for a shorter distance in the axial direction than the widened portion of the support.</p> |
