A multi-angle laser beam projector including a metal base block having a first tapered through hole and a second tapered through hole intersected with the first tapered through hole, the first tapered through hole having one end terminating in a laser beam inlet and an opposite end terminating in a first reflecting hole, the inner diameter of the first tapered through hole being made gradually bigger from the laser beam inlet toward the first reflecting hole, the second tapered through hole having one end terminating in a second reflecting hole and an opposite end terminating in a laser beam outlet, the inner diameter of the second tapered through hole being made gradually bigger from the second tapered through hole toward the laser beam outlet, a first reflector covered over the first reflecting hole and having a reflecting surface for reflecting light from the laser beam inlet onto the second reflecting hole, and a second reflector covered over the second reflecting hole and having a reflecting surface for reflecting light from the first reflector toward the laser beam outlet.
