1. A leveling, plumbing, and angular calibration instrument (1) comprising:
a swinging suspended vertical body (4), which for creation and emission of laser light carries at least one of a light element, lens, beam splitter, or beam converging element;
a clamping arrangement allocated to the vertical body (4) for limiting or blocking the swinging motion, having a clamping element (7) allocated to the vertical body (4) preventing the swinging motion at a predetermined position, when necessary, which includes at least two clamping shoes (8, 9) arranged opposite in reference to each other, which are synchronously displaceable or pivotal, or displaceable and pivotal in reference to a clamping section (10) of the vertical body (4).
