Abstract
A laser extender is provided for accurately elongating a reference line. The laser extender includes a housing, a battery set, and a laser unit. The housing has an external basic flat plane for resting upon a flat surface and having a straight edge that is adapted to be aligned with a reference line, an internal accommodating space, and a plurality of through holes for accessing the internal accommodating space from the exterior of the housing. The battery set is provided inside the internal accommodating space. The laser unit, utilizing power provided by the battery set, is located inside the internal accommodating space for generating a spanning plane laser beam perpendicular to the basic flat plane of the housing and for extending the reference line defined by the straight edge. In addition, the laser extender can engage a beam leveler for enhancing the leveling ability of the laser extender.
