Instrument for obtaining a reference line to realize, in correspondence of this line, working points, said working points being preferably situated in correspondence of a working surface. The instrument includes: a laser ray emitting device (1), a supporting body (13), connecting means which attach it to a fixed reference surface. These connecting means include a hinge element (2) which enables to orientate the supporting body (13) and direct the laser ray and to keep it fixed in the desired direction in such a way that with the line defined by the laser ray it is possible to find the working points.

1. An instrument for obtaining a reference line in order to identify working points relative to said reference line, said instrument comprising:a device (1) for emitting a ray of laser light; a supporting body (13) for said laser light emitting device (1); means (2, 22) for connecting the supporting body (13) of the laser emitting device (1) to a reference surface (20), said means (2, 22) for connecting comprising a hinge means (2) which enables orientation of the supporting body (13) such that the ray of laser light is directed in desired directions and so that the ray of laser light is adapted to trace a reference line along which a plurality of working points can be identified on the reference surface (20), said hinge means (2) adapted to receive an associated fastener to fixedly secure said hinge means to the reference surface, wherein said supporting body (13) is movable relative to the reference surface in different directions along at least two different planes.
