Background technique

The monitor is an I/0 device belonging to the computer, that is, an input and output device. With the advent of the information age, computers and networks have almost become an important part of people's work and life, especially for young and middle-aged people. However, "computer diseases" caused by improper use of computers have also followed, among which cervical spondylosis is the most common. Mostly manifested as cervical spine stiffness, shoulder and arm pain, finger numbness, dizziness and so on. It is mainly due to the tension and strain of the muscles around the cervical spine caused by improper use of the computer, and the degeneration of the cervical intervertebral disc and joints. For example, a family of three uses one monitor at the same time, so the fixed display cannot meet everyone's needs in terms of distance from front to back, height from top to bottom, and viewing angle. Special attention should be paid to children who are growing. Long-term incorrect postures are more likely to affect the normal development of children. The monitor stand came into being. The monitor stand is a product that can fix monitors, notebooks or tablet computers, etc. It can help solve various technical problems that people encounter when operating computers at home or in commercial offices. Its ergonomic design can prevent work fatigue. To prevent health problems, improve work efficiency, and bring an ideal space for living and working.
