Title: Laser projection device for projecting orthogonal laser-lines

Abstract: A laser projection device with multiple functions comprises a casing, a locating leg and two support legs associated with the lower end of the casing respectively, a transverse bar provided in the casing, a heavy weight pivotally engaging with the transverse bar, and a vertical laser line indicating module and a horizontal laser point indicating module fitting with the heavy weight respectively. The vertical laser line indicating module emits a vertical indicating line and the horizontal laser point indicating module emits indicating points. The vertical indicating line and the horizontal indicating line are orthogonal to each other, and the tip of the locating leg is right on a vertical plane of light and right under the horizontal indicating line.
