[0026] Specifically, when the operator clicks the system return to origin command, the output end of the servo motor 3 drives the connecting shaft 4 to rotate, and this rotation process will be transmitted to the spur bevel gear 1 5, and then drive the spur bevel gear 2 6 meshing with it to rotate, so that the focusing lens 7 can be rotated. When the origin sensing piece 9 touches the origin sensor 8, the return to origin is completed, which means the end of the automatic zoom process. Next, by pressing the sliding column 12, it slides inside the fixed plate 11. This sliding process will drive the semi-circular ball 16 to slide inside the fixed block 10. The semi-circular ball 16 will squeeze the buckle plate 15 inside the fixed block 10 to make it slide. This process will further squeeze The spring 14 is pressed. When the semicircular ball 16 completely passes through the snap plate 15, the spring 14 will rebound, driving the snap plate 15 to slide. At this time, the sliding column 12 is pulled, and the semicircular ball 16 will slide into the interior of the hollow semicircle 13. This process will cause the snap plate 15 to shrink, so that the protective cover 26 can be pulled. At this time, the protective cover 26 no longer blocks the shooting of the focusing lens 7. On the contrary, when the protective cover 26 is needed to protect the focusing lens 7, it is only necessary to keep the hollow semicircle 13 in this state. At this time, the semicircular ball 16 will slide out from the inside of the hollow semicircle 13, and then be directly inserted into the inside of the fixed block 10. In this way, the protection of the focusing lens 7 is completed.

[0027] Reference Figure 1 and Figure 5 The support assembly includes a support plate 17, the support plate 17 is fixedly connected to the side wall of the body 1, the side wall of the body 1 is fixedly connected to a support block 18, the side wall of the support plate 17 is rotatably connected to a rotating rod 19, the side wall of the support plate 17 is rotatably connected to a rotating rod 20, the side wall of the rotating rod 19 is rotatably connected to a connecting block 21, and the rotating rod 20 is rotatably connected to the side wall of the connecting block 21;

[0028] Specifically, the rotation of the rotating rod 19 and the rotating rod 20 on the side wall of the support plate 17, and the linkage effect of the connecting block 21, greatly enhance the portability and mobility of the focusing lens 7, which not only simplifies the carrying process, but also enables the body 1 to easily adapt to the working environment that requires frequent movement or installation, which greatly improves the work efficiency and ease of use. In addition, through the support plate 17, the stability of the focusing lens 7 during the movement and installation process is ensured, avoiding the risk of equipment damage or performance degradation due to frequent movement.

[0030] Specifically, pulling the handle 25 will drive the movable plate 24 to rotate, and the rotation of the movable plate 24 realizes the rotation of the connecting plate 23 and the connecting block 21. In this process, the rotation of the connecting plate 23 and the connecting block 21 plays a key role. At the same time, this also ensures the stability of the body 1, and avoids damage to the equipment due to looseness of the connection parts during movement. The rotation of the connecting block 21 also drives the stretching of the spring 22. The spring 22 plays a buffering and protective role, avoiding damage to the equipment due to impact during movement.

[0031] Working principle: when it is necessary to automatically zoom the focusing lens 7, the operator first clicks the system return to origin command, and then the output end of the servo motor 3 drives the connecting shaft 4 to rotate, and the rotation of the connecting shaft 4 will drive the spur bevel gear 1 5 to rotate, and the rotation of the spur bevel gear 1 5 will drive the spur bevel gear 2 6 meshing with it to rotate, and the rotation of the spur bevel gear 2 6 will drive the focusing lens 7 to rotate, and the origin sensing sheet 9 touches the origin sensor 8 before returning to the origin. When it is necessary to open the protective cover 26, by pressing the sliding column 12 to slide inside the fixed plate 11, the sliding column 12 will drive the semi-circular ball 16 to slide inside the fixed block 10, and the semi-circular ball 16 will squeeze the snap plate 15 to slide inside the fixed block 10. The sliding of the snap plate 15 will squeeze the spring 14, and then when the semi-circular ball 16 completely passes through the snap plate 15, the spring 14 will rebound and drive the snap plate 15 to slide, and then pull the sliding column 12, which will cause the semi-circular ball 16 to slide into the hollow semicircle 13, and then The buckle plate 15 squeezes the spring 14 to shrink, and the protective cover 26 can be pulled at this time, and the protective cover 26 will no longer block the shooting of the focusing lens 7. When the protective cover 26 is needed to protect the focusing lens 7, the hollow semicircle 13 is kept in this state, and the semicircular ball 16 will slide out from the inside of the hollow semicircle 13, and then directly inserted into the inside of the fixed block 10 to complete the protection of the focusing lens 7. When the staff needs to carry and move the machine body 1, first, by pulling the handle 25, the handle 25 will drive the movable plate 24 to rotate, and the rotation of the movable plate 24 will drive the connecting plate 23 and the connecting block 21 to rotate, and the rotation of the connecting block 21 will stretch the spring 22 and drive the rotating rod 19 to rotate on the side wall of the support plate 17. At the same time, the connecting block 21 will also drive the rotating rod 20 to rotate on the side wall of the support plate 17, so that it is convenient to carry and move the focusing lens 7, and it is more convenient to carry the machine body 1 to a working place that needs to be frequently moved or installed.
