[0002] As a new type of multimedia interactive teaching terminal, the interactive all-in-one machine integrates the functions of multimedia devices such as electronic whiteboard, short-throw projector, amplifier, audio, computer, video stand, central control, wireless headset, cable TV, etc. There are many multimedia teaching all-in-one machines on the market. Based on the display method, they can be divided into whiteboard all-in-one machines and LCD all-in-one machines. In order to meet the usage needs of different groups of people, the existing interactive all-in-one machines are usually installed on a liftable bracket, and the interactive all-in-one machine is raised and lowered by the lifting bracket.

Under normal circumstances, the movable rod can drive the second gear to engage with the first gear under the action of the limit spring, so that the first gear and the threaded rod cannot rotate. When lifting and lowering adjustment is required, the second gear can be moved away from the first gear by pulling the movable rod, so that the threaded rod can rotate normally.
