Multifunctional optical lens group

The utility model relates to the field of optical lens groups, in particular to a multifunctional optical lens group, which comprises a lens barrel, a plurality of optical lenses fixedly arranged in the lens barrel, a lens cover in threaded connection with the end part of the lens barrel, and a protection assembly for protecting the lenses, and the protection assembly is connected with the lens cover through a buffer assembly. The beneficial effects of the utility model are that not only can the optical lens be effectively protected so as to effectively prevent the optical lens from being damaged, but also the protection assembly can be effectively buffered and protected so as to prevent the optical lens from being damaged. Therefore, the protection assembly is effectively prevented from being damaged due to external force impact and losing the protection function on the optical lens, continuous protection operation on the optical lens is effectively guaranteed, practicability is effectively improved, and the
