[0042] The adjustment component includes a connecting column 29, one end of which is fixedly connected to one end of a knob 10, and the connecting column 29 is driven to rotate by rotating the knob 10 to achieve angle adjustment. A limiting groove 11 is provided inside the connecting column 29, and the limiting groove 11 is used to cooperate with a limiting block 25 to prevent the connecting column 29 from axial displacement during rotation, thereby maintaining the smoothness of the adjustment process. A connecting column 18 is slidably connected inside the connecting column 29, and the connecting column 18 can slide inside the connecting column 29 during adjustment, thereby facilitating transmission adjustment. A worm 5 is fixedly connected to one end of the connecting column 18, and the worm 5 is meshed with a worm wheel 6.

A locking groove 20 is provided inside the connecting sleeve 14. The locking groove 20 is used for the engagement of the card block 17 to ensure the reliability of the connection. The connecting sleeve 14 is internally slidably connected with a limiting plate 3 21. The sliding design of the limiting plate 3 21 facilitates the in and out adjustment of the card block 17. The limiting plate 3 21 is internally fixedly connected with a support column 22. The support column 22 provides additional support strength for the whole structure to ensure the stability of the structure during the adjustment process. One end of the support column 22 is fixedly connected to a top block 23, and the top block 23 realizes the unlocking operation by pushing the card block 17. The outer wall of the support column 22 is sleeved with a second spring 24, and the second spring 24 plays a reset role to ensure that the top block 23 automatically returns to its initial position after the unlocking operation. One end of the second spring 24 is fixedly connected to one side of the limit plate three 21, and the other end of the second spring 24 is fixedly connected to one side of the top block 23.

A telescopic rod 3 18 is arranged inside the connecting pin 13. The telescopic rod 3 18 helps the card block 17 to be connected through its telescopic adjustment function. The positioning and resetting operation of the block 17 ensures that the structure always maintains appropriate tension during the adjustment process. The outer wall of the telescopic rod 3 18 is provided with a first spring 19. The first spring 19 provides the resetting force of the telescopic rod 3 18 to ensure that the block 17 can be quickly reset when adjusting or removing the lens 4. The telescopic rod 3 18 and one end of the first spring 19 are fixedly connected to the bottom of the limit plate 2 15 to ensure the stability of the entire structure. The other ends of the telescopic rod 3 18 and the first spring 19 are fixedly connected to the inside of the connecting pin 13. The design of fixing both ends improves the stability and operational flexibility of the overall structure, and further ensures the simplicity and stability of the replacement of the lens 4.

Subsequently, the user can separate the old lens 4 from the connecting pin 13 through the connecting sleeve 14 and remove it. Next, just insert the new lens 4 into the outer wall of the connecting pin 13 through the connecting sleeve 14 to ensure that the new lens 4 is accurately in place. At this time, the block 17 in the connecting pin 13 will automatically embed into the locking groove 20 to ensure that the lens 4 is firmly and does not fall off. The block 17 is accurately limited inside the connecting pin 13 by the support rod 16 and the limiting plate 15, and is further supported by the tension of the first spring 19 to ensure that the block 17 is firmly embedded in the locking groove 20 and is not easy to slide out. After the operation is completed, release the support column 22, and under the tension of the second spring 24, the top block 23 will quickly reset, and the entire structure will return to its initial state. In this way, not only is the operation simple, but the lens 4 can also be replaced quickly, which greatly improves the convenience of use and the efficiency of operation.
