Abstract: A mechanism for vertically adjusting a component on a shaft has a collet sleeve riding on the shaft. A spiral track of the component's hub receives a radially outwardly projecting pin on the collet sleeve. The outer surface of the collet sleeve and the inner surface of the hub are tapered so that the hub can rotated one direction to advance the hub on the collet sleeve and compress the collet sleeve onto the shaft to frictionally lock the collet sleeve to the shaft. Because the hub is joined to the collet sleeve by the pin, this also locks the vertical position of the component. Conversely, the hub can be oppositely rotated to release the compression of the collet sleeve so that the collet sleeve, and therefore the vertical component, is slidable on the shaft.
