Measurement work e.g. angle marking, performing level for secondary sector of building and public work sector, has articulations interdependent with each other and fixed on common axle, where articulations have angle reading locations

摘要

The level has two articulations (9, 10) that are interdependent with each other and fixed on a common axle i.e. locking screw (4), where the articulations have angle reading locations. The articulation (9) has an axle i.e. locking screw (5), traversing a support part (12). The axle (4) traverses the articulation (10). The articulation (10) is fixed on a support part (11). The articulation (9) has graduations in degrees from 180 to 90 degrees and from 90 to 0 degrees. The parts (11, 12) are hollow for receiving the articulations.
