[0016] The beneficial effects of the present invention are mainly manifested in the following aspects: 1. In the present invention, a flip transmission rod, a reduction transmission assembly, a first coupling, a second coupling, a driving motor assembly, and an upper limit switch and a lower limit switch for flipping the optical mirror are arranged in the optical mirror frame.

In addition, by setting the flip angle range of the optical mirror through the electronic control system, it can ensure that the optical mirror stays accurately at the target position, so that the optical mirror has redundant protection, thereby improving the safety and stability of beam path switching and reducing operational risks.

[0019] Fourth, the present invention adopts an input transmission member with a specific structure, which can achieve self-locking without an additional locking mechanism. Even under power failure or external force, the optical mirror can still be kept in the target position to ensure stability in use.

The support base is fixed on the optical mirror frame and is driven by a stepper motor. It is organically combined with an input transmission member of a specific structure to achieve automatic light beam path switching. Compared with the prior art, it improves adjustment accuracy and reduces human errors.

[0021] VI. In the present invention, a rotating handle is provided on the stepping motor, and the rotating handle is connected to the motor shaft of the stepping motor. By providing the rotating handle, manual adjustment is allowed during power-off or debugging stages, avoiding the inability to switch due to electrical faults and improving flexibility and emergency response capabilities.

The double lead worm 16 and the double lead worm gear 17 are connected by gear meshing transmission.

[0067] One end of the double - lead worm 16 penetrates through the first rolling bearing 13 and contacts the first worm end cover 15. The other end of the double - lead worm 16 sequentially penetrates through the second rolling bearing 14, the adjusting shim 18, and the second worm end cover 19.

[0068] The drive motor assembly 7 includes a support base 20 and a stepper motor 21 mounted on the support base 20. The support base 20 is fixed to the optical mirror frame 2.

[0069] A rotating handle 22 is provided on the stepper motor 21. The rotating handle 22 is connected to the motor shaft of the stepper motor 21.

[0070] The optical mirror frame 2 is provided with a first installation cavity 23 and a second installation cavity 24. The second installation cavity 24 is larger than the first installation cavity 23.

[0071] The drive motor assembly 7, the first coupling 5, the speed - reducing transmission assembly 4, and the second coupling 6 are all installed in the first installation cavity 23.

[0072] The flipping transmission rod 3 is installed in the second installation cavity 24. Two flexible support blocks 25 for supporting the upper part of the optical mirror 1 are arranged in the second installation cavity 24. The two flexible support blocks 25 are arranged in a "one" shape.

[0073] This embodiment is the best implementation mode. The flipping transmission rod 3 is installed in the second installation cavity 24. Two flexible support blocks 25 for supporting the upper part of the optical mirror 1 are arranged in the second installation cavity 24. The two flexible support blocks 25 are arranged in a "one" shape, which can provide elastic support when the optical mirror 1 moves to the cut - out state. While ensuring the precise positioning of the optical mirror 1, it can avoid structural deformation caused by vibration or external force, and ensure the long - term reliable operation of the optical system.

[0074] The working principle of the present invention is as follows: During the flipping adjustment process, the drive motor assembly 7 generates a rotational motion, which is transmitted to the input end of the speed - reducing transmission assembly 4 through the first coupling 5. After the speed - reducing transmission assembly 4 reduces the speed and increases the torque, the rotational motion is transmitted from the output end to the flipping transmission rod 3 through the second coupling 6, thereby driving the optical mirror 1 to perform a flipping motion. The flipping motion of the optical mirror 1 is mechanically and software - limited by the upper limit switch 8 and the lower limit switch 9. When the optical mirror 1 moves to the cut - out state, the upper part of the optical mirror 1 contacts the flexible support block 25.

[0075] The input transmission part 11 of the speed reduction transmission assembly 4 adopts a double-lead worm and worm gear structure. The left and right gears of the double-lead worm 16 have different leads, and the double-lead worm gear 17 is consistent with the double-lead worm 16, with left and right different tooth surfaces machined. By assembling adjustment shims 18 of different specifications, the double-lead worm 16 is axially moved, so that the tooth thickness of the meshing part of the double-lead worm 16 and the double-lead worm gear 17 continuously changes, thereby adjusting the gear backlash of the speed reduction transmission assembly 4 to achieve high-precision repeated positioning and backlash-free self-locking.
