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.
Claims10
A laser projection device with multiple functions, comprising:
- a casing with a lower end and an upper end, and having two studs extending outwardly from the lower end;
- a locating leg, having a tip, and extending from the casing on said lower end thereof;
- two support legs, supporting the lower end of said casing;
- a transverse bar, provided in the casing;
- a weight with a first hole and a second hole therein, the weight pivotally engaging the transverse bar;
- a vertical laser-line indicating module, located in the first hole in the weight;
- and
- a horizontal laser point indicating module, located in the second hole in the weight;
- such that said vertical laser-line indicating module emits a vertical indicating-line, said horizontal laser point indicating module emits indicating points to constitute a horizontal indicating-line, the vertical indicating-line and the horizontal indicating-line are orthogonal to each other, and the tip of said locating leg is on a vertical plane of light and under the horizontal indicating line.
