A device (10) for clamping and unclamping a standing prism pole (11) within a surveying instrument (13). A pair of opposing vise or jaw members (24, 25) are disposed with a geometrical configuration (18) forming a frame (19) having a cavity (20), the one vise (24) within cavity (20) fixedly mounted to frame (19), the other vise (25) within cavity (20) slidably movable towards and away from vise (24), and by which the standing prism pole (11) is clamped and unclamped by the jaw members (24, 25). A spacer arm (34) connects frame (19) to a support leg (37) of instrument (13). At the bottom of leg (37) a carrying handle (39) is connected for ease of moving instrument (13) from one point to another in either collapsed or uncollapsed mode for instrument (13).
