Novel optical lens with adjustable PI position

The utility model relates to a novel optical lens with adjustable PI position, including the lens cone, its technical essential does, is equipped with lens cone shift adjusting's carrier block relatively on the lens cone, is fixed with the PI component on the carrier block, still is equipped with on the lens cone to electrically conduct the circuit board of being connected with the PI component. The utility model discloses simple structure improves the camera lens and becomes doubly the crowd when long burnt position, and the crowd that focuses that the surplus is not enough can't be to the clear condition. 本实用新型涉及种PI位置可调节的新型光学镜头，包括镜筒，其技术要点为，镜筒上设有可相对镜筒移动调整的承载块，承载块上固定有PI元件，镜筒上还设有与PI元件导电连接的电路板。本实用新型结构简单，改善镜头变倍群在长焦位置时，对焦群对焦余量不足无法对清的情况。
