1. A camera optical lens, comprising, from an object side to an image side:
a first lens having a positive refractive power;
a second lens having a negative refractive power;
a third lens having a positive refractive power;
a fourth lens having a positive refractive power;
a fifth lens having a positive refractive power;
a sixth lens having a negative refractive power;
a seventh lens;
an eighth lens having a positive refractive power; and
a ninth lens having a negative refractive power,
wherein the camera optical lens satisfies following conditions:
2.00≤f1/f≤4.50;
2.93≤(R3+R4)/(R3−R4)≤10.67;
0.30≤R13/R14≤1.30, and
3.00≤d9/d10≤12.00,
where
f denotes a focal length of the camera optical lens,
f1 denotes a focal length of the first lens,
R3 denotes a central curvature radius of an object side surface of the second lens,
R4 denotes a central curvature radius of an image side surface of the second 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,
d9 denotes an on-axis thickness of the fifth lens, and
d10 denotes an on-axis distance from an image side surface of the fifth lens to an object side surface of the sixth lens.
