Camera optical lens

A camera optical lens comprising, from an object side to an image side in sequence:

• a first lens, a second lens having a positive refractive power, a third lens having a negative refractive power, a fourth lens, a fifth lens, and a sixth lens;
• wherein the camera optical lens consisting of six lenses, and further satisfies the following conditions:
• 0.5≤f1/f≤10;
• 2.28≤(R5+R6)/(R5−R6)≤4.80;
• −3.25≤(R9+R10)/(R9−R10)≤−1.67;
