The switching mirror, when the power source drives the switching mirror to rotate, in the state of the first rotation angle and the second rotation angle, the laser beam is reflected to the first direction and the second direction respectively. 11. The laser mirror conversion light source mechanism according to claim 7, wherein the switching unit includes a plurality of switching mirrors and the power source, and a plurality of switching mirrors includes a first switching mirror and a second switching mirror, when The power source is to drive a plurality of switching mirrors to rotate in a rotating manner. In the state of the first rotation angle, the first switching mirror receives the laser beam and reflects the laser beam to a first direction, and in the state of the second rotation angle. The state is that the second switching mirror receives the laser beam and reflects the laser beam toward a second direction.
