The rotation axis 8 of the laser transmitter 1 is connected to the water fan 14 in the damping water tank 2 to prevent the laser transmitter 1 from shaking and keep the laser light 3 still quickly. After the laser beam 3 is still, judge whether the steel beam and column are vertical and horizontal and the inclination angle of the component by the position of the laser point on the horizontal inclination angle scale plate 4 and the vertical inclination angle scale plate 5.
