Abstract
The invention provides a projection device which includes a rotating module and an imaging module. The rotating module is assembled on a mounting surface and includes a rotating part and an assembling part which are integrally formed. The rotating part is parallel to the mounting surface, and the assembling part is perpendicular to the mounting surface. The imaging module is assembled on the assembling part of the rotating module. When the rotating module rotates by taking an axis perpendicular to the mounting surface as an axial center, the rotating module drives the imaging module to rotate so as to change a projection direction of the imaging module. The projection device of the invention adjusts the projection direction without using a tool.
