Disclosed is a projector (1), comprising a projector body (10) with a lens (12), and a light reflection assembly (20) for adjusting a projecting direction of the lens (12). The light reflection assembly (20) comprises a reflective mirror (23), and the light reflection assembly (20) is provided to be rotatably connected with the projector body (10). During the rotation, a mirror face of the reflective mirror (23) always faces towards the lens (12), so that the reflective mirror (23) adjusts the angle of the projecting direction between the mirror face and the lens (12) with the rotation of the light reflection assembly (20), so as to adjust the projecting location of the lens (12) by means of the rotation of the reflective mirror (23), such that the projecting direction can be changed without moving the projector (1).
