Abstract
The utility model discloses a laser angle measuring gauge which is composed of a gauge body, a first stand bar, a second stand bar, a first laser device and a second laser device. The gauge body is provided with a rotary shaft, a display screen, a power button and an angle-radian switch button. Upper ends of the first stand bar and the second stand bar are respectively fixed on the rotary shaft, and lower ends of the first stand bar and the second stand bar are respectively fixedly connected with the first laser device and the second laser device. Laser emission directions of the first laser device and the second laser device are in accordance with length directions of the first stand bar and the second stand bar. Measured angles are displayed by the display screen. The laser angle measuring gauge is simple in structure and convenient to use, and non-contact type measurement of various angles is achieved.
