instrument for determining plans, however, angled and distant compared to a basic plan, usable as level and / or thread

摘要

the instrument consists of a set of convenient length and cross section, provided with a graduation and a measure of the angle.the ruler is inserted an emitter beam, preferably a laser diode.prepared in such a way that the beam emitted is parallel or vertical with respect to the support base of the ruler and possibly tangent to this base.the instrument is completed by a battery power source of the laser beam, and a switch to activate or deactivate the source itself.in addition, on a face of the ruler or the base, can oscillate a needle indicator is also provided such that the modulation index.the angular displacement to indicate the values of inclination with respect to the horizontal, the plan on which the tool supports.the index is provided with a counterweight which tends to get him in the vertical with respect to the floor support.with the source of the beam of radiation, laser or light.on one of the transverse faces of straight edge base and along the central axis of the slide rule and munendo the surface opposite a suitable hook.the instrument is to be a real wire to lead with the radius of action prolonged according to the demand of the emitter of the radius.
