Abstract

The invention, which belongs to the technical field of information technology devices, provides a multimedia device for information technology teaching. A lifting device includes a lifting platform, alifting rod, and a servo motor a. The lifting platform being a flat plate is installed at the upper ends of the lifting rod and a linkage rod; the lifting rod is installed inside the lifting device in a sliding manner; the upper end of the lifting rod is fixedly welded with the lifting platform; and the servo motor a is installed outside the lifting platform and is connected with a control systemelectrically. According to the invention, because of the lifting device arranged at the traditional teacher desk and a precise locking device, a computer can be placed in the teacher desk and a phenomenon that any student carries out operation due to the curiosity under an unattended condition and even the computer is damaged is avoided. When carrying out multimedia teaching, the teacher does notneed to take a portable computer all the time, so that the workload of the teacher is reduced.
