Abstract
A photosensitive element is adjustably mounted on a device, including a base frame having a flat base and a ball socket perpendicularly extended from the flat base and defining a half-round recess, the flat base having a center through hole through the center of the half-round recess for the insertion of a photosensitive element being connected to a light source through an electric wire, a core member, which has a ball head at one end received and turned within the half-round recess, an outer thread at an opposite end, a longitudinal through hole aligned with the center through hole on the base frame, and a lens mounted within the longitudinal through hole, and a socket shell, which has an inner thread at one end threaded onto the outer thread of the core member, a longitudinal through hole aligned with the longitudinal through hole on the core member, and a lens set mounted within the longitudinal through hole and matched with the lens on the core member.
