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;
1.50≤(R3+R4)/(R3−R4)≤3.00;
−0.45≤(R9+R10)/(R9−R10)≤−0.14;
