Claim 0:
1. A camera optical lens comprising, from an object side to an image side:
a first lens;
a second lens having a negative refractive power;
a third lens;
a fourth lens;
a fifth lens;
a sixth lens;
a seventh lens;
an eighth lens; and
a ninth lens,
wherein the camera optical lens satisfies following conditions:

0.70≤f1/f≤1.90;

−10.02≤f6/f≤−2.53;

−1.19≤(R13+R14)/(R13−R14)≤0.48; and

2.00≤d5/d6≤9.00,

where
f denotes a focal length of the camera optical lens,
f1 denotes a focal length of the first lens,
f6 denotes a focal length of the sixth lens,
R13 denotes a central curvature radius of an object side surface of the seventh lens,
R14 denotes a central curvature radius of an image side surface of the seventh lens,
d5 denotes an on-axis thickness of the third lens, and
d6 denotes an on-axis distance from an image side surface of the third lens to an object side surface of the fourth lens.
