Problems solved by technology

[0003] At present, the optical lenses arranged at zero distance in the light source of 3LCD educational projectors on the market are often fixed and supported by a single pressing piece and the housing. This fixing method not only requires a more complicated housing bracket, but also requires relatively high processing accuracy. It is harsh, the processing cost is high, and the reliability of the two lenses fixed by only one shrapnel is not enough, and relative deviation may occur
In addition, there is another way of fixing is to fix by glue on the surface of the lens, so that on the one hand, the glue on the surface of the lens will more or less affect a part of the optical path and reduce the light effect; There is volatilization in the glass, which will pollute the lens, and the way of viscose is not easy to disassemble and difficult to assemble
