发明名称 V-level
摘要 The V-Level will give an accurate and an exact level reading, rather than having to read an ordinary level twice, to obtain a level or plumb of two perpendicular planes, at a ninety degree angle to each other. You can now have six bubbles to level, plum, and square, 'exactly' in one movement. Leveling walls, floors, tile, and framing can be done in one simple step.
