Self-adjusting automatic laser level-meter

The utility model relates to a self-adjusting automatic laser level-meter. The utility model is characterized in that a machine casing and a laser generating device which is arranged in the machine casing are provided with openings which are supported by a blade. The bottom of the laser generating device is fixed and forms a damped pendulum of a magnetic damping with a damped block of the bottom of the machine casing. A motor is arranged in the laser generating device to drive a scanning barrel. The laser which is generated in the laser generating device of the scanning barrel is reflected by a reflector to form a laser beam which rotates horizontally and is ejected from the opening of the machine casing. The utility model has the advantages that the utility model can generate the accurate horizontal laser which generates a laser horizontal line or a laser horizontal plane on the space background which is needed to position or mark and can adjust the horizon of the laser automatically. The utility model can be widely used for the position and the mark of the spatial horizontal reference or plane of the industries, such as the building, the decoration, etc.
