Description
Technical field
The utility model relates to a kind of teaching aid, particularly relates to a kind of Novel mathematics teaching apparatus.
Background technology
In daily mathematical education, mathematics teacher often needs to draw parallel lines, vertical line, leg-of-mutton high on blackboard, when drawing above-mentioned line segment with traditional teaching aid, teacher usually switches back and forth by several teaching aid and draws, and usually locate by subjective observation when drawing, this not only adds the work difficulty of teacher, affect efficiency of giving lessons, and drafting effect is also undesirable.
Summary of the invention
The technical problems to be solved in the utility model is the deficiency for technique scheme, provides the drafting difficulty that can alleviate various line segment, conveniently draws a kind of Novel mathematics teaching apparatus of parallel lines, vertical line, leg-of-mutton high various line segment.
In order to solve the problem, the utility model by the following technical solutions:
A kind of Novel mathematics teaching apparatus, mainly comprise ruler (1), set square (2) and draw round belting receiver (3) etc., it is characterized in that: described ruler (1) is provided with the handle (4) of band anti-slip veins, ruler is provided with chute in (1), described set square (2) is fixedly connected with two slide blocks (7), and two described slide blocks (7) are embedded in the chute of ruler (1) by being slidably connected.
Further, described slide block (7) is for I-shaped, and it comprises embedded block (8) and pole (9).
Further, two described slide blocks (7) are adhered to the bottom of set square (2) by plastic bar.
Further, described ruler (1) is provided with a clasp (10), linen thread (5) one end lies on clasp (10), and the other end connects a chalk draw-in groove (6), is connected with chalk in described chalk draw-in groove (6).
The beneficial effects of the utility model are: ruler body is fixed on blackboard by being with the handle of anti-slip veins by teacher or student, parallel lines, vertical line, leg-of-mutton high various line segment is drawn by slip set square, can also clasp be that circle is drawn in the center of circle, adopt this instructional device, not only conveniently can fix drawing tool, and draw effect accurately, improve efficiency of giving lessons.
