Patent ID: 8478120

Claim:
A camera lens, comprising: a lens-barrel fixing base, having a hollow part disposed at a central position of the lens-barrel fixing base, a first supporting part disposed in a peripheral area of the hollow part, and a connecting part disposed at an external periphery of the first supporting part; a driving barrel, being a hollow barrel structure, and having a groove formed at an inner wall of the driving barrel, and the driving barrel being disposed in a fixing barrel, and an end of the fixing barrel being coupled to the connecting part; a focusing lens-barrel, being a hollow barrel structure, and having a guiding part disposed on an external wall of the focusing lens-barrel and inserted into the groove, such that the focusing lens-barrel is able to be disposed and axially moved in the driving barrel, and a second supporting part being disposed at an inner wall of the focusing lens-barrel; and an elastic member, being a hollow-ring structure axially extendible and contractible, and being disposed between the lens-barrel fixing base and the focusing lens-barrel, one end of the elastic member fixed to and supporting the first supporting part of the lens-barrel fixing base, and another end of the elastic member fixed to and supporting the second supporting part of the focusing lens-barrel, and a radial cross-sectional area at the end of the elastic member being greater than a radial cross-sectional area at the another end of the elastic member; wherein the elastic member has a non-stretched length smaller than a distance between the first supporting part of the lens-barrel fixing base and the second supporting part of the focusing lens-barrel.
