[0018] In the drawings, the same structural parts and structural parts with the same function are denoted by the same reference numerals.
[0019] in figure 1 The marking and / or leveling device 1 is shown in a schematic diagram. The marking and / or leveling device includes a housing 2 and a pendulum 3 that is supported relative to the housing 2 so as to be deflectable relative to the housing 2 in all spatial directions. The pendulum 3 is configured as a rigid connecting rod element and carries a light source 4 configured as a laser diode on its lower end in the plane of the drawing, which is used to generate a laser beam 5 in a point or line shape along the cross section. With this laser beam, a point-like or linear horizontal laser line can be projected onto the projection plane.
[0020] On the upper end of the light source 4 in the plane of the drawing, the hard pendulum 3 has a ball head 6 which forms a self-adjusting bearing 8 together with an annular bearing receiver 7. The ...
