Abstract
The fixing structure of the micro projector includes a base, a plurality of abutting members and a plurality of fixing components. The base has an assembling plane. The abutting members are respectively disposed on the assembling plane. Each abutting member has an abutting wall, and each optical lens is abutted against each corresponding abutting wall. The fixing components are respectively disposed on the assembling plane and correspond to the abutting walls respectively, and each fixing component fixes each corresponding optical lens on each corresponding abutting wall. Based on this, there is no need to apply adhesives for fixing the optical lens. Additionally, upon assembling the optical lens, since no adhesives are applied it is not necessary to adjust the angle of the optical lens thereby improving the convenience of assembly and reducing the assembly time.
