Auxiliary education teaching device

Abstract

The invention discloses an auxiliary education teaching device. The device comprises a control device; the upper surface of the control device is fixedly connected with a first electric telescopic rod; the top of the first electric telescopic rod is fixedly connected with a motor; the right side of the motor is fixedly connected with a second electric telescopic rod; the right end of the second electric telescopic rod is fixedly connected with a push dust suction device; the push dust suction device comprises a sleeve; the left side of the sleeve is fixedly connected with the right end of thesecond electric telescopic rod; and the front end of the sleeve is fixedly connected with the motor. Through the cooperation between the structures, problems that in actual use process, dust adsorption effect is poor due to the fact that a sucker is far away from chalks, the chalks are shorter and shorter in the using process, it is difficult for a traditional fixed end to push the clamped chalkscontinuously in the using process to make end parts of the chalks be in continuous contact with blackboard surfaces, and inconvenience is caused during usage are solved.

[0002] Computer-assisted teaching is a variety of teaching activities carried out with the assistance of computers. It discusses teaching content, arranges teaching progress, and conducts teaching training methods and techniques with students in a dialogue manner. Application field, it is not only an important application field of computer in education, but also represents a new educational technology and teaching method, CAI provides students with a good personalized learning environment, comprehensive application of multimedia, hypertext, artificial intelligence and knowledge Computer technology such as computer library overcomes the single and one-sided shortcomings of traditional teaching methods. Its use can effectively shorten learning time, improve teaching quality and teaching efficiency, and achieve optimal teaching goals; however, most of the product equipment currently on the market It is difficult to draw pictures on the blackboard, and in science and engineering subjects, the drawing of graphics is particularly important. At present, most of the pictures still need to be drawn by teachers, which is time-consuming and laborious, and the accuracy is not high enough. An auxiliary education and teaching device, such as a computer-aided education and teaching equipment disclosed in Chinese patent CN107341973A, includes a mounting plate, a suction cup is provided on the bottom end surface of the moun
