1. A camera optical lens, comprising from an object side to an image side:
a first lens having positive refractive power;
a second lens having negative refractive power;
a third lens having positive refractive power;
a fourth lens having negative refractive power;
a fifth lens having positive refractive power; and
a sixth lens having negative refractive power,
wherein a total number of lenses in the camera optical lens is 6,
wherein the camera optical lens satisfies:
6.50≤f3/f≤10.00;

where
f denotes a focal length of the camera optical lens,
f3 denotes a focal length of the third 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,
R9 denotes a curvature radius of the object side surface of the fifth lens,
R10 denotes a curvature radius of an image side surface of the fifth lens,
d1 denotes an on-axis thickness of the first lens,
d2 denotes an on-axis distance from an image side surface of the first lens to the object side surface of the second lens,
d7 denotes an on-axis thickness of the fourth lens, and
d8 denotes an on-axis distance from an image side surface of the fourth lens to an object side surface of the fifth lens.
