English word random generation device based on auxiliary memory

Abstract

The invention discloses an English word random generation device based on auxiliary memory, and belongs to the field of English learning tools. The English word random generating device based on the auxiliary memory comprises a shell body; a containing groove is formed in the upper surface of the shell body; the two inner side surfaces of the containing groove are provided with adjusting sliding grooves; the inner side surfaces of the adjusting sliding grooves are connected with adjusting sliding blocks in a sliding mode; the outer ends of the adjusting sliding blocks are fixedly connected with round rods; positioning ball-shaped grooves are formed in the outer surfaces of the round rods; the adjusting sliding blocks and the round rods are symmetrically connected to the two inner side surfaces of the containing groove; the outer surfaces of the round rods are rotationally connected with mounting plates through round holes; the outer surfaces of the mounting plates are connected to theinner side surfaces of the containing groove in a sliding mode; and positioning ball heads are arranged at the two ends of the inner side surface of each round hole. Therefore, the convenience and stability of use can be greatly improved, and the safety and efficiency of word memory learning are ensured.

Description

technical field [0001] The invention relates to the field of English learning appliances, more specifically, to a device for randomly generating English words for aiding memory. Background technique [0002] In the process of learning English, the most important thing is to memorize words. In order to facilitate learning and consolidation, it is necessary to test the memorized words, which is conducive to deepening memory. In order to ensure the randomness of the test, it is necessary to randomly select words for testing to improve the learning effect. . [0003] With the development of science and technology, the use of intelligent display systems is becoming more and more common, which can assist people in memorizing and checking words. [0004] However, most of the existing word random generating devices are to fix the display screen on the outer casing, so that the angle of the tilting mode cannot be adjusted according to the usage habits, which is not conducive to view...

AI Technical Summary

Problems solved by technology

[0004] However, most of the existing word random generating devices are to fix the display screen on the outer casing, so that the angle of the tilting mode cannot be adjusted according to the usage habits, which is not conducive to viewing, and it cannot be turned over to the lower end for protection, which is easy to be damaged during storage. Scratches and poor security. At the same time, when randomly generating words, the word library cannot be preset. It is easy to exceed the learning range, which is not conducive to learning and testing. Moreover, it is not convenient to control each time a word is generated, and the use effect is not ideal.
