Problems solved by technology
[0003] In mathematics teaching, it is often necessary to draw circles, straight lines and other drawing tools for drawing. Usually, mathematics teachers will carry a lot of teaching tools such as compass and compass, but these teaching materials are large in size and not easy to carry. It is inconvenient for teachers to operate when drawing, therefore, there is an urgent need for a portable mathematics teaching tool for education

The invention belongs to the technical field of education and teaching, and discloses a portable mathematics teaching appliance for education. The portable mathematics teaching appliance for educationcomprises a suitcase; baffles are movably connected to the left side and the right side of the upper end of the suitcase through pin shafts; first limiting blocks are fixedly installed at the lower ends of the two baffles and located on the sides, close to the suitcase, of the two baffles. According to the portable mathematics teaching appliance for education, through a first auxiliary block in acircle drawing mechanism, a teacher opens a first limiting block, takes out the first auxiliary block from a first corresponding containing groove and controls an LED screen to input a correspondingangle value, and then the teacher lifts up a vertical rod; first sliding blocks and second sliding blocks in first rectangular grooves and second first rectangular grooves are matched with through hinges, so that rectangular rods on two sides can improve angle control; after a positioning block is attached to a blackboard, a motor drives a second rectangular plate to rotate to draw a circle, so that the circle drawing diameter is controlled, and the situation that the circle is irregular due to manual drawing is avoided.
Description
technical field [0001] The invention relates to the technical field of education and teaching, in particular to a portable mathematics teaching tool for education. Background technique [0002] In a narrow sense, education refers to specially organized school education; in a broad sense, it refers to social practice activities that affect people's physical and mental development. The word "education" comes from Mencius's "get the world's talents and educate them". The Latin word educare is the source of the word "education" in the West, which means "leading out". Educators educate the educated's mental development in a planned and organized manner in accordance with laws, regulations and industry norms, according to school conditions and professional titles. Cultivation is to teach people with existing experience and knowledge to explain various phenomena, problems or behaviors to improve their practical ability. It basically treats things with a relatively mature or ration...
