Abstract

A repositionable supporting apparatus includes a lower post adapted to be fixed on a worktable. An upper post is disposed co-axially rotatable relative to the lower post, and has a downward abutment wall defining an upper cavity, and an anchored end portion connected to an anchoring end of a cantilever member. The cantilever member has a holding end opposite to the anchoring end in a direction radial to the upper post for carrying a workpiece feeding device. A coupling member couples the lower post with the upper post in both retained and released positions where the upper post is prevented from rotation and is rotatable relative to the lower post respectively, and has an upward abutment wall to slidably contact the downward abutment wall such that a lower cavity therein can be aligned and communicated with the upper cavity. A spring biased tumbler pin is disposed in and is movable relative to the lower cavity between a locked position where the tumbler pin protrudes into tne upper cavity, and an unlocked position where the tumbler pin is retracted by depression of a depressing member to be flush with the upward abutment wall so as to permit sliding movement of the downward abutmen…
