1. A camera optical lens comprising six-piece lenses, from an object side to an image side, the six-piece lenses are:
a first lens having a positive refractive power;
a second lens having a negative refractive power;
a third lens having a negative refractive power;
a fourth lens;
a fifth lens having a positive refractive power; and
a sixth lens having a negative refractive power;
wherein the camera optical lens satisfies following conditions:
0.35≤f1/f≤0.50;
−30.00≤R4/R3≤−2.00;
1.50≤(R5+R6)/(R5−R6)≤30.00;
2.06≤(R9+R10)/(R9−R10)≤8.20; and
0.05≤d9/TTL≤0.13,
where
f denotes a focal length of the camera optical lens;
f1 denotes a focal length of the first lens;
R3 denotes a curvature radius of an object-side surface of the second lens;
R4 denotes a curvature radius of an image-side surface of the second lens;
R5 denotes a curvature radius of an object-side surface of the third lens;
R6 denotes a curvature radius of an image-side surface of the third lens;
R9 denotes a curvature radius of the object-side surface of the fifth lens;
R10 denotes a curvature radius of the image-side surface of the fifth lens;
d9 denotes an on-axis thickness of the fifth lens; and
TTL denotes a total optical length from an object-side surface of the first lens to an image surface of the camera optical lens along an optical axis.
