ABSTRACT:
A laser measuring device includes a housing, a laser head, two levels, a power supply, and a control knob. Thus, the housing has a non-symmetrical structure, so that when one of the casings of the housing is removed, the adjusting screws of the laser head are entirely exposed outward from the housing, thereby facilitating adjustment of the laser head and the levels.
