Single-handedly operable apparatus associated with a cutting board, adapted for retaining a workpiece and comprising a post (3) rigidly attached to a cutting board (1) adapted for mounting on a horizontal substructure, as well as a hanger (4) mounted one the post for adjustment in height and with means (5) for engagement against a workpiece. The hanger (4) is carried on the post (3) by a slide (6) which is adjustable to, and fixable at, a given height. The slide (6) has a first latching means (9) which is manually engageable against the post (3) for fixing the slide at a desired height. The slide (6) has a substantially horizontally orientated guide (8) accommodating the hanger (4) to allow horizontal, glideable displacement of the hanger. The hanger (4) and guide (8) have a plurality of mutual co-action attitudes, predetermined by their respective configurations, with respect to the angular attitude of the hanger (4) about its longitudinal axis in the guide (8) for variable orientation of the means (5) on the hanger for engagement with the workpiece in different directions. The guide (8)carries a second latching means (12), which is manually engageable against the hanger (4) for fixing the latter in a desired axial position in the guide. |
