the second transmission gear comprises a second gear main body with a circular tubular structure, a plurality of continuous second driving teeth are arranged on the outer side wall of the second gear main body, and a clamping part is arranged at one end of the second gear main body;
the second gear main body is rotatably sleeved on the adjustable ring, and the clamping part on the second gear main body is clamped with the adjusting rod;
the driving gear is used for driving the second gear main body to rotate around the axis direction of the driving gear main body through rotation, and the second gear main body rotates around the axis direction of the driving gear main body to drive the adjusting rod to rotate so as to adjust the clear aperture of the adjustable diaphragm.
6. The corneal crosslinking apparatus of claim 5, wherein the second drive teeth are in external engagement with the drive gear.
7. The corneal crosslinking apparatus of claim 5, wherein the drive gear is coupled to the second drive gear by a gear ring belt.
8. The corneal crosslinking apparatus according to any one of claims 5-7, wherein the drive mechanism further comprises a second rotary electric machine;
the second rotating motor is connected with the supporting frame, and an output shaft of the second rotating motor is connected with the driving gear;
the second rotating motor is used for driving the driving gear to rotate according to the electric control signal so as to drive the second gear main body to rotate through the driving gear.
9. The corneal crosslinking apparatus of claim 1, wherein the apparatus further comprises: an optical assembly comprising at least one lens;
the optical assembly is arranged on the supporting frame, and a lens included in the optical assembly is positioned in the direction of the ultraviolet laser transmitter to emit laser.
10. The corneal crosslinking apparatus of claim 9, wherein the adjustable optical ring is positioned between any adjacent two lenses comprised by the optical assembly.
