Abstract
A laser projection apparatus has an adjustment platform having a base seat, a platform portion that is adjustably coupled to the base seat, and an adjustment mechanism that is operatively coupled to the base seat and the platform portion to adjust the inclination angle of the platform portion with respect to the base seat. The apparatus also has a frame body that is connected to the adjustment platform, and a column that is suspended by the frame body and which is separated from the adjustment platform by a distance. The apparatus further includes a first projection light-source mechanism that is connected to the column and which projects a straight light that is parallel to a central axis, and a second projection light-source mechanism which is connected to the column and which projects a light ring that is transverse to the central axis.
