A projector, comprising:

• a light source, configured to provide an illumination light beam;
• a light valve, disposed on a transmission path of the illumination light beam, and configured to convert the illumination light beam into an image light beam;
• a projection lens, disposed on a transmission path of the image light beam, and configured to project the image light beam out of the projector;
• and
• an optical module, comprising:
• a first frame body, rotatably connected to a base body along a first axis, wherein the first frame body has a first adjusting portion, and the first adjusting portion is configured to drive the first frame body to rotate along the first axis;
• a second frame body, rotatably connected to the first frame body along a second axis, wherein the second frame body has a second adjusting portion;
• an adjusting member, screwed to the first adjusting portion, wherein the adjusting member is adapted to move along the first axis relative to the first adjusting portion, so as to push the second adjusting portion to drive the second frame body to rotate along the second axis;
• and
• an optical element, disposed on the second frame body and located on the transmission path of the illumination light beam.
