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 positive refractive power;
a third lens;
a fourth lens having a positive refractive power; and
a fifth lens having a negative refractive power,
wherein the camera optical lens satisfies following conditions:
2.10≤f1/f≤4.00;
1.00≤d4/d6≤3.00; and
0.20≤d8/d9≤0.90,
where
f denotes a focal length of the camera optical lens;
f1 denotes a focal length of the first lens;
d4 denotes an on-axis distance from an image side surface of the second lens to an object side surface of the third lens;
d6 denotes an on-axis distance from an image side surface of the third lens to an object side surface of the fourth lens;
d8 denotes an on-axis distance from an image side surface of the fourth lens to an object side surface of the fifth lens; and
d9 denotes an on-axis thickness of the fifth lens.
