Abstract:
A multifunction laser leveling tool (1) is provided. The multifunction laser leveling tool (1) comprises: a housing (2); a pendulum (28) supported by the housing (2) via a universal joint so that the pendulum (28) is pivotable with respect to the housing (2) around a first axis (24) and a second axis (26) perpendicular to the first axis (24); a locking means (4) which is able to fixedly lock the pendulum (28) to the housing (2) and to release the pendulum (28) therefrom, wherein when the pendulum (28) is released, the pendulum (28) is in a plumb orientation and the first and second axes (24,26) lie in a horizontal plane; a first laser beam emitter (36) attached to the pendulum (28) for emitting a first laser plane; an angle sensing means (44) attached to the pendulum (28) for measuring the orientation of the pendulum (28); a display module having two sections (6,8) attached to the housing (2) for displaying the measured orientation of the pendulum (28).
