A constructional
laser including a housing (3) with a
light source located inside the housing for emitting a
visible laser beam rotatable about a
rotational axis, a base plate (11) attached to the housing (3) and provided with an inner thread (25) approximately in a center of the base plate (11), and two handles (12, 13) for lifting and carrying the
laser and connected to the base plate (11) with the two handles (12, 13) being spaced from opposite sides of the housing (3) and extending at a right angle from the base plate (11) parallel to a height of the housing (3) toward an upper surface (4) of the housing (3), with the handles (12, 13) having at sides thereof remote from the housing (3), three
servo positioners (14, 15, 16), with two of the
servo positioners (14, 15) being provided on one
handle (12) and with the third, height-adjustable
servo positioner (16) being arranged on another
handle (13), the three-point arrangement of the servo positioners (14, 15, 16) defining an isosceles triangle, with the connection lines between the three forming lateral side(s) of the isosceles triangle.
