摘要: The invention relates to the field of drawing tools, in particular a multifunctional tool. tool comprises shell, clamping unit, right turning wheel, leftturning an adjustment displayer and controller. shell is cuboid structure. A threaded through groove penetrating lower end face formed upper unit mounted groove. stretching-out block arranged on front shell. An open side block, arc-shaped sliding grooves are faces groove, resistor blocks grooves, laser scaleplates blocks. left wheel both located under at correspondingly. two ends rotatably supports. top supports fixedly connected with used for adjusting angle wheel. has characteristics being small size, low weight convenient carry andis suitable teachers, students engineering technicians.
