Patent ID: 7423814

Claim:
A camera lens focus-setting mechanism, said camera lens including a first lens holder located at a front end of said camera lens, a second lens holder located at a rear end of said camera lens, and a first and a second focusing ring rotatably mounted around said first and said second lens holder, respectively, so that rotating of said first and said second focusing ring would bring said first and said second lens holder, respectively, to shift forward or rearward; said focus-setting mechanism comprising: a first rack member associated with said first focusing ring on said first lens holder, and including a radially outward projected lower end, on and along an upper side of which a curved first rack is extended, and said first rack being concentric with a ring body of said first focusing ring; a second rack member associated with said second focusing ring on said second lens holder, and including a radially outward projected lower end, on and along an upper side of which a curved second rack is extended, and said second rack being concentric with a ring body of said second focusing ring; a first adjusting assembly including a first turning bar, and a first gear driven to rotate by said first turning bar; said first gear meshing with said first rack on said first rack member, so that said first gear being rotated by said first turning bar is able to cause said first focusing ring to rotate synchronously; and said first turning bar being provided at an outer end surface with a slot for engaging with a corresponding driver tip; and a second adjusting assembly including a second turning bar, and a second gear driven to rotate by said second turning bar; said second gear meshing with said second rack on said second rack member, so that said second gear being rotated by said second turning bar is able to cause said second focusing ring to rotate synchronously; and said second turning bar being provided at an outer end surface with a slot for engaging with a corresponding driver tip.
