Abstract
An angle-adjustable projection mechanism and a projector are provided. The adjustable angle projection mechanism includes a light source assembly, a condenser lens, a projection pattern assembly and an adjustable reflecting mirror assembly arranged sequentially along an optical path. A light beam emitted by the light source assembly is concentrated by the condenser lens and then passes through the projection pattern assembly and illuminates the adjustable reflecting mirror assembly. The adjustable reflecting mirror assembly includes a rotation adjustment member and a reflecting mirror, the rotation adjustment member is configured to drive the reflecting mirror to rotate to adjust a mirror angle of the reflecting mirror.
