Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Example:

[0026] See also Figure 1-Figure 5 The figure shows an optical adjustment mechanism suitable for a radio frequency CO2 laser, comprising a laser body 1 fixed to a mounting plate, a correction block 3 disposed outside a light outlet 2, a connecting assembly 4, and an auxiliary assembly 11. The laser body 1 is provided with a light outlet 2 on the outside, a correction ring 5 is disposed within the inner cavity of the correction block 3, and a correction lens 6 is disposed within the correction ring 5. The correction lens 6 is a convex lens. Evenly distributed adjustment rods 7 are disposed on the outside of the correction ring 5, and a first screw 8 is disposed on the portion of the adjustment rod 7 located inside the correction block 3.

[0027] An adjusting block 9 is provided on the outer thread of the first screw 8, and a slot 17 is provided on the side of the adjusting block 9 away from the corrective lens 6. Evenly distributed slide rails 18 are fixed in the inner cavity of the corrective block 3, and the slide rails 18 slide in cooperation with the slots 17 to prevent the adjusting block 9 from rotating when moving on the first screw 8. The adjusting rod 7 is rotatably arranged in the inner cavity of the corrective block 3, and a first rotating wheel 14 is fixed on the end of the adjusting rod 7 away from the corrective block 3 to facilitate the rotation of the first screw 8. A fixing ring 10 is provided on the outside of the corrective lens 6, and the corrective lens 6 is fixed inside the fixing ring 10. The adjusting block 9 is connected to the fixing ring 10 through the connecting component 4, and an auxiliary component 11 for adjusting the vertical position of the corrective lens 6 is arranged in the corrective block 3.

[0028] Some embodiments of the present application are described in detail below with reference to the accompanying drawings:

[0029] See also Figure 1-Figure 5 The first screw 8 is driven to rotate by the adjusting rod 7, thereby driving the adjusting block 9 to move back and forth in the inner cavity of the correction block 3, thereby driving one side of the correction lens 6 to move back and forth through the connecting component 4, thereby adjusting the deflection angle of the correction lens 6.

[0030] Among them, the connecting component 4 includes a connecting head 12 and a connecting seat 13. The connecting head 12 is fixedly arranged on the outside of the adjusting rod 7. The middle part of the connecting head 12 is a telescopic rod, which can adapt to the movement of the adjusting block 9. The connecting seat 13 is provided with multiple connecting heads 12 corresponding to each other. Multiple connecting seats 13 are evenly fixed on the outside of the fixing ring 10. The connecting head 12 is embedded in the connecting seat 13. The deflection of the corrective lens 6 is controlled respectively by multiple groups of connecting heads 12 and connecting seats 13, and the adjustment accuracy is higher. The connecting head 12 is rotatably connected to the connecting seat 13. The end of the connecting head 12 is spherical, and the end of the connecting head 12 is embedded in the spherical groove in the connecting seat 13 to realize the free rotation of the connecting head 12, ensuring that the connecting head 12 moves smoothly back and forth with the adjusting block 9.

[0031] In the implementation of the present technical solution, the auxiliary component 11 includes a second screw 15, and there are multiple second screws 15. The second screw 15 is threadedly connected to the outer side of the correction block 3. A second rotating wheel 16 is fixed to the outer end of the second screw 15. The outer sides of the first rotating wheel 14 and the second rotating wheel 16 are both provided with anti-slip grooves to prevent slipping when the fingers twist. The end of the second screw 15 away from the second rotating wheel 16 is arranged in the inner cavity of the correction block 3, and the end of the second screw 15 away from the second rotating wheel 16 is against the outer side of the correction ring 5. The width of the correction ring 5 is equal to the width of the inner cavity of the correction block 3 to adjust the vertical and lateral positions of the corrective lens 6.

[0032] It is worth noting that Figure 5 As shown, the first screw 8 and the second screw 15 are respectively distributed in a triangular shape outside the corrective lens 6 to achieve multi-directional adjustment of the corrective lens 6.

[0033] The first screw 8 is rotated by the first rotating wheel 14, driving the adjustment block 9 to slide back and forth in the inner cavity of the correction block 3, thereby driving the corresponding side of the correction lens 6 to move back and forth through the connecting head 12 and the connecting seat 13, and adjusting the deflection direction and deflection angle of the correction lens 6. At the same time, the second screw 15 is rotated by rotating the second rotating wheel 16. Since the second screw 15 is against the outside of the correction ring 5 and is not fixed to the correction ring 5, the vertical and lateral positions of the correction lens 6 are adjusted by adjusting the screw-in depth of the three second screws 15 distributed in a triangular shape, and the deflection angle of the correction lens 6 is adjusted by cooperating with the first screw 8 to correct the optical path of the light outlet 2 of the laser body 1.
