Abstract
The utility model relates to a drawing ruler, composed of four horizontal, longitudinal flat rulers. The both ends of each horizontal flat ruler and the both ends of each longitudinal flat ruler are connected to form a parallelogram through pin joint. The utility model has the advantage of easy use. Various parallel geometrical drawings can be drawn out conveniently.
Description
Technical field the utility model relates to a kind of drawing apparatus, especially a kind of picture chi.
Technical background often will be drawn various parallel geometric figures in daily learning life, it is very difficult to use common drawing ruler to draw.
The summary of the invention the purpose of this utility model provides a kind of convenient various parallel geometric picture chis of drawing.
For achieving the above object, the utility model is drawn chi and is made up of four horizontal strokes, vertical ruler, scalable two anyhow chi two ends and two indulge the ruler two ends by being articulated and connected into the parallelogram shape.
After adopting said structure, earlier telescopic ruler is adjusted to suitable length, select suitable parallel angle, just can draw out various parallel geometric figures easily after fixing the picture chi.
The utility model has the advantages that: easy to use, can draw out various parallel geometric figures easily.
Description of drawings Fig. 1 draws the chi structural representation for the utility model.
The specific embodiment such as Fig. 1 show, the utility model is drawn chi and is made up of four horizontal strokes, vertical ruler, scalable two anyhow chi 1 two ends and two indulge ruler 2 two ends by being articulated and connected into the parallelogram shape.After using said structure, earlier telescopic ruler is adjusted to suitable length, select suitable parallel angle, just can draw out various parallel geometric figures easily after fixing the picture chi.
