Self-leveling line generator |
摘要 |
A self-leveling line generator may be removably disposable on a surface. The line generator includes a housing carrying a light source for emitting a light beam and a lens holder for carrying a lens that converts the light beam to a planar beam. The lens holder is movable with respect to the light source housing and is self-leveling so that the planar beam is in a fixed orientation on the surface on which the planar beam contacts.
