摘要:
A device for holding a target adjacent first and second intersecting surfaces of a structure to assist in measuring a distance from an instrument to the target. The device has first and second levers that are joined by a pin that has a section that extends above the levers to receive the target. A force is applied to the first and second levers to bring non-skid pads thereon into engagement with the intersecting surfaces. The target is thereafter rotated into parallel alignment with the second surface and the instrument is aligned with the first surface. A signal transmitted from the instrument is reflected from the target to provide a direct measurement of the distance from the instrument to the target.
