1. A camera optical lens, comprising, from an object side to an image side in sequence: 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 having a positive refractive power, and a fifth lens having a refractive power; wherein the camera optical lens satisfies the following conditions:
8.00≤f;
0.90≤f/TTL;
0.40≤f1/f≤0.85;
−1.10≤f3/f4≤−0.40;
0.30≤d2/d4≤2.00; and
9.00≤R6/R5≤30.00;
where,
f: a focal length of the camera optical lens;
f1: a focal length of the first lens;
f3: a focal length of the third lens;
f4: a focal length of the fourth lens;
TTL: a total optical length from the object side surface of the first lens of the camera optical lens to an image surface of the camera optical lens along an optical axis;
d2: an on-axis distance from an image side surface of the first lens to an object side surface of the second lens;
d4: an on-axis distance from an image side surface of the second lens to an object side surface of the third lens;
R5: a central curvature radius of the object side surface of the third lens; and
R6: a central curvature radius of an image side surface of the third lens.
