[0004] The above-mentioned mirror polishing device fixes an arc-shaped clamping block at the output end of the telescopic device. When the telescopic assembly extends forward, the clamping block is driven to move horizontally, thereby fixing the lens. However, the mirror polishing device cannot adjust the angle of the lens after fixing it. When the lens surface is irregular, the mirror polishing device cannot grind and polish the lens surface. Therefore, the inventor proposes a positioning device that is convenient for lens polishing, installation and fixation to solve the above-mentioned problem. Summary of the invention

The lens is fixed from the edge by the fixing device to avoid occupying the surface space of the lens when fixing, resulting in insufficient polishing. The problem that the polishing device cannot polish the irregular lens surface and the fixture needs to occupy the surface space of the lens is solved.
