Embodiment Construction

[0011] Such as figure 1 As shown, the design consists of a semicircular protractor 1, a small rivet 2, a ruler 3, a large rivet 4 and a folding ruler 5. When the length needs to be measured, only the semicircle protractor 1 or the folding ruler 5 is rotated into a straight line for measurement, and the teacher can choose whether to use the semicircle protractor 1 or the folding ruler 5 to measure according to the measured length. When you need to measure different angles, draw different angles, and demonstrate parallelograms, rectangles, squares, rhombuses, triangles, etc., you only need to rotate the ruler 3 and the folding ruler 5 appropriately, and use the folding ruler 5, ruler 3, and half With the cooperation of the circular protractor 1, the above-mentioned various teaching demonstrations can be carried out very conveniently. When the multi-functional teaching tool is used up, it is only necessary to rotate and fold the ruler 3 together, and then rotate the folded ruler...

Abstract

The invention discloses a combined type multifunctional teaching appliance. By means of the combined type multifunctional teaching appliance, the problems that existing teaching appliances are singular in function and cannot be stored easily or carried conveniently are solved. The combined type multifunctional teaching appliance is characterized in that a semicircular protractor and rulers adoptedin the prior art are included; the rulers are hinged through small-size rivets, and each ruler can rotate relative to another; the multiple rulers are hinged to form folding rulers; the two folding rulers are hinged to the protractor through a large-size rivet, and therefore, the two folding rulers can horizontally rotate at will relative to the semicircular protractor; each folding ruler can horizontally rotate at will relative to the other folding ruler; the large-size rivet is located at the semi-circle center of the semicircular protractor; and the length of each ruler is equal to the radius of the semicircular protractor. The combined type multifunctional teaching appliance is simple in design, convenient to use, low in cost and easy to popularize.
