Abstract
The present invention is to provide a laser leveling device that can generate a laser line at arbitrary angular positions within a predetermined angle range. The laser leveling device includes a housing, a laser generating module for generating a fan-shaped laser line on a vertical object surface to form a laser line thereon. The laser generating module is connected to the housing with a shaft-connection structure having an axis perpendicular to the vertical object surface, The laser leveling device further includes an electronic inclinometer module provided inside the housing and fixed relative to the laser generating module, and an electronic display module for displaying the angle of the laser line rotating around the axis with respect to a reference line. With this structure, the user can visually observe the angle of the laser line with respect to the reference line to conveniently and rapidly set the laser line in a desired angle.
