[0002] A projector, also known as a projection machine, is a device that can project images or videos onto a screen and can be connected to a computer, VCD, DVD, BD, game console, DV, etc. through different interfaces to play corresponding video signals. Currently, it is widely used in families, offices, schools, and entertainment venues. According to different working methods, there are different types such as CRT, LCD, and DLP.

[0003] The existing projectors are not convenient for dual use on the tabletop and the wall, resulting in the inability to determine the placement position of the projector according to the specific needs of the users.

Also, they are not convenient for rotating and adjusting the projection height, resulting in a limited projection range and inconvenience for people to use. Therefore, the utility model provides a rotatable projector. Content of the Utility Model
