Abstract
The invention relates to a multi-function teaching ruler. The multi-function teaching ruler comprises straight line ruler bodies and a protractor with angle tick marks, wherein the straight line ruler bodies comprise a first ruler body and a second ruler body. The left end of the first ruler body is hinged to the left end of the second ruler body in a way of being reversible up and down. The bottom surface of the first ruler body is connected with the top surface of the second ruler body in a clamping way. Length tick marks which are distributed along the length direction are arranged on the front side faces of the first ruler body and the second ruler body. An arc-shaped sliding groove which is distributed around a coordinate center is formed in the protractor. The protractor is fixed at the left end of the rear side face of the second ruler body. A fixed column which rotates around the coordinate center is connected in the sliding groove in a sliding way. The fixed column is provided with external thread and an indicating needle which points to the angle tick marks is fixed at the top of the fixed column. One end of the fixed column is fixed at the left end of the rear side face of the first ruler body and the tread of the other end of the fixed column matches a fastening bolt in a connecting way. The teaching rule can be used as a teaching stick and a straight ruler and can be used for angle measurement or drawing. The teaching ruler is diverse in function.

Summary of the invention
The technical problem to be solved is to provide a kind of multifunctional teaching ruler, to overcome above-mentioned deficiency.
For solving above-mentioned technical problem, the present invention provides techniques below scheme: multifunctional teaching ruler, including straightedge rule body, with the protractor of angle index line, described straightedge rule body includes rectangular-shaped the first chi body, is positioned at the rectangular-shaped second chi body below the first chi body, described first chi body left end can be articulated with the left end of the second chi body with spinning upside down, the bottom surface of described first chi body and the end face clamping of the second chi body, described first chi body, the second chi body leading flank on be provided with the length scale line being alongst distributed；The arc slide slot around coordinate central distribution is offered on described protractor, described protractor is fixed on the second chi body trailing flank left end, one is slidably connected around the fixing post of coordinate center rotating in described slide slot, be fixed with the instruction pin of orientation angle graduation mark on described fixing post with external screw thread and top, described fixing post one end is fixed on the first chi body trailing flank left end, the other end is threaded is combined with fastening bolt.
On the basis of such scheme, described first chi body, the length of the second chi body are 50-75cm.
On the basis of such scheme, described first chi body, the length of the second chi body are 50cm.
On the basis of such scheme, described first chi body bottom surface downwardly extends out card article, and described second chi body end face is embedded with draw-in groove, and described first chi body is connected in the second chi body by card article with the realization that coordinates of draw-in groove.
On the basis of such scheme, described first chi body end face extends upward semi-cylindrical extension.
The present invention compared with prior art has the beneficial effect that the teaching ruler that the present invention provides, and after the first chi body is connected on the second chi body by it, whole teaching ruler may act as teaching pole and uses；The trailing flank of teaching ruler is set level and is made leading flank be placed in top by it, just the second chi body can be served as ruler, be used for drawing straight line with reference to length scale line；It is by the first chi body rotating opening, and fixing post is easy in slide slot rotate, and by instruction pin it is observed that the angle rotated, in order to measure angle or to meet the needs about angle for angle etc. of drawing, and can be used for the setting-out on longer angle limit.
