ABSTRACT:
A laser leveling device includes a laser instrument disposed in a housing, a plate slidably received in the housing and a lens attached to the plate. The lens includes two or more portions having different patterns to generate different light beams when the laser instrument generates the light through either of the portions of the lens, by moving the plate relative to the housing. The plate includes an aperture movable to align with the laser instrument, to allow the light beam to selectively emit through the aperture of the plate directly, without emitting through the lens. A switch may be disposed in the housing and actuated by the plate when either the aperture or the lens of the plate is aligned with the laser instrument.
