Abstract

A foldable multifunctional teaching aid disclosed by the present invention comprises a rotating main shaft, a base ruler, a rotating ruler, a folding ruler and a clamping mechanism, one end of the base ruler is fixedly connected with the opposite bottom side surface of the rotating main shaft, the top of one end of the rotating ruler is fixedly connected with a circular ring sleeve, and the circular ring sleeve rotatably sleeves the rotating main shaft and is located above the base ruler. One end, far away from the base ruler, of the back edge of the rotating ruler is hinged to one end of the back edge of the folding ruler. The sum of the lengths of the base ruler and the folding ruler is equal to the length of the rotating ruler. The multifunctional teaching aid integrates multiple functions, can achieve the functions of drawing circles and straight lines and measuring angles, is convenient to carry, simple in structure, ingenious in design, stable in function and efficient in action, and solves the problems that existing teaching aids are various in use variety and inconvenient to carry.
