The invention provides a teaching ruler with magnetic suction blocks. Several magnetic suction blocks are arranged on the back surface of a ruler body of the ruler. When a teacher uses the ruler on the blackboard in classes, the ruler can be adsorbed on the blackboard through the magnetic suction blocks, so that the ruler is favorably smoother and more convenient in classes.
Description
technical field [0001] The invention relates to a teaching aid used in schools, in particular to a teaching ruler with a magnetic suction block. Background technique [0002] When school teachers give lectures, they often use a teaching ruler to draw straight lines on the blackboard. Because the traditional ruler is only a ruler, it is used on the blackboard. It must be pressed firmly by hand. If you are not careful, it will slide and directly It affects teaching and makes teachers feel very inconvenient and tired. Contents of the invention [0003] The invention provides a teaching ruler with a magnetic suction block, which can be used by absorbing the ruler on a blackboard, avoiding sliding and being convenient to use. [0004] The invention includes a scale body of a ruler, and the adopted technical solution is that the ruler is equipped with several magnetic suction blocks on the back of the scale body. [0005] The beneficial effect of the present invention is that:...
