Abstract
A laser level includes a transparent container, a buoy with a built-in laser component, and a support frame. The center of gravity of the buoy is always at the center of the buoy. One end of the buoy emits horizontal laser beams, the other end thereof emitting vertical laser beams. Two spindles respectively extend from both sides of the center of the buoy such that the spindles are perpendicular to the body of the buoy. The distance between the distal ends of the spindles is equivalent to the internal width of the container. Brackets are disposed on the inner wall of the container at a suitable height. The buoy is mounted on the brackets by means of the spindles to achieve balance and stability. The container is supported on the support frame so that it can be placed on surfaces of any uncertain plane. The container is filled with a liquid to the bottom rim of the buoy so that the buoy is always kept level on the liquid and the laser beams emitted from the buoy are always horizontal and vertical to achieve precise measurement.
