AI Technical Summary

Problems solved by technology

[0004] (1) The current common projectors are inconvenient to freely adjust the angle during use, and are subject to relatively large restrictions during use, which is not conducive to use;

[0005] (2) The traditional projector does not have a shock absorbing device when it is installed and adjusted, which is easy to cause damage to the inside of the projector and reduce the service life of the projector
