Description

Technical Field

[0001] The utility model relates to a teaching tool, in particular to a multi-purpose computer teaching device. Background Art

[0002] With the popularization of computer applications and the advent of the Internet age, it is having a significant impact on society and various fields. Computer courses have become compulsory courses for students at all stages of study. At present, most of the teaching tables used in computer classrooms are fixed structures and the height of the desktop cannot be adjusted. For students with large height differences, some taller or shorter students cannot use a comfortable sitting posture to operate the computer, and the teacher's desk is also mostly fixed. When teaching, the teacher can only operate the computer in a sitting posture, which is not only easy to cause fatigue, but also inconvenient to observe the learning status of each student. For this reason, we propose a multi-purpose computer teaching device. Utility Model Content
