[0070] The function set for the shift plate 2 can be infrared light, laser, LED light or light of different intensities, or other functions.

[0071] The second technical solution of the present invention is as follows Figure 10 、 11 A fine-tuning mechanism shown in FIG. 1 includes a fine-tuning nail 8, a fine-tuning limit cylinder 9 and a fine-tuning pin 10, as shown in FIG. Figure 12 As shown, the fine-tuning pin 8 includes a fine-tuning side 801 and a pushing side 802, and also includes a positioning boss 803.

[0072] like Figure 13 、 14As shown, the fine-tuning limit cylinder 9 includes an upper cylinder 901 and a lower cylinder 902. The inner diameter of the upper cylinder 901 is smaller than the outer diameter of the positioning boss 803. A plurality of fine-tuning grooves 903 corresponding to the second limit spring 804 are uniformly arranged axially on the inner side of the fine-tuning limit cylinder 9. A positioning through hole 904 corresponding to the positioning chamfer 1001 is opened at the bottom of the fine-tuning limit cylinder 9.

[0073] It also includes a cover 11 arranged on the outside of the fine-tuning side 801, such as Figure 16 As shown, the cover body 11 is cylindrical, and the top is a cover through hole 1101.

The functions of the shift plate 2, the conductive sheet 4, the toggle position 301 and the limit groove 104 correspond to each other, and the assembly is completed; finally, the external thread of the switch base 1 is threadedly connected to the body 12 and glued, and the installation of the toggle switch mechanism is completed. When working, you only need to twist the knob switch 3, and the knob switch 3 will drive the conductive sheet 4 to move. The conductive sheet 4 slides on the shift plate 2, and twist the knob switch 3 to the corresponding label, so that the conductive sheet 4 is connected to the circuit of the corresponding shift plate 2. When switching, you only need to twist the knob switch 3 again to connect the conductive sheet 4 to the circuit of the corresponding shift plate 2.

[0080] Regarding the second technical solution, a fine-tuning mechanism is first assembled, and the fine-tuning pin 8 is threadedly connected to the fine-tuning pin 10 inside the fine-tuning pin 8; secondly, the fine-tuning pin 10 is placed inside the positioning through-hole 904, and the positioning boss 803 falls on the upper end of the fine-tuning limit cylinder 9; thirdly, the cover body 11 is installed, and the cover body 11 is sleeved with the fine-tuning pin 8.

When the position of the light source is offset, the fine-tuning pin 8 is adjusted, and the positioning pin 806 is fine-tuned in the fine-tuning slot 903. The fine-tuning pin 8 moves, driving the fine-tuning pin 10 to move slightly forward and backward. The end of the fine-tuning pin 10 contacts the light source, and the position of the light source is fine-tuned by adjusting the fine-tuning pin 8.

[0081] In summary, in order to solve the problems mentioned in the prior art that when multiple functions need to be switched with each other, the switching process is cumbersome, the required structure is complex, the stability cannot be guaranteed, the adjustment of the light source emission angle has low precision and cannot achieve fine-tuning, the present invention provides a toggle switch mechanism and a fine-tuning mechanism.
