The utility model relates to the laser field, in particular to a light path automatic lens changing system of a multi-wavelength laser. The laser emits lasers with different wavelengths from different output windows; an automatic lens changing device drives a driving pulley to rotate through a stepping motor and transmits motion to a driven pulley through a belt; the driven pulley drives a gear to rotate; the mesh of gear racks enables the rotation of the gear to be converted into linear motion of a guide rail mobile platform to drive the guide rail mobile platform to move, and accordingly, an optical lens support of a laser on the guide rail mobile platform moves to the output windows corresponding to the wavelength of the laser, and an optics lens support of a laser with another wavelength can fold automatically through the control of a motion control card at the moment; the heights of the lens supports are adjusted to enable lenses and laser emitting openings to be in a same horizontal plane; and according
