Spirit level for mechanical engineering

The utility model relates to an engineering apparatus technical field especially relates to spirit level for mechanical engineering. Whether parallel can survey the whether level of plane of inspecting through the bubble of inside including setting up of main level pipe, whether setting up of water gauge to both sides can to detect a plurality of planes parallel if being adjusted, solved and measured a plurality of quick -witted machining plane when, the unable measuring problem of light water leveling ruler, the design consideration of quick dish is required at ordinary times, can fix a position vice level pipe fast to indicate the constant angle degree, and work efficiency is high, accurate adjustment dish and transition disc's design can realize vice level pipe hi -Fix, adjust setting up of water gauge and can also measure the contained angle between machined surface and the horizontal plane through the scale mark, the design of whole device both can have been fixed a position fastand also can have been me
