[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model. Embodiment

[0021] Please refer to Figures 1-4 , the present utility model provides the following technical solutions: A fundus camera fixing and adjusting device includes a base 1, a box body 2 and a fundus camera body 3. The fundus camera body 3 belongs to an existing mature medical device, and its model is: SZX1-DM6C. Therefore, the specific working principle will not be elaborated too much. The fundus camera body 3 is assembled inside the box body 2, the box body 2 is arranged on the top end of the base 1, the bottom end of the box body 2 is connected with a docking block 7, the top end of the base 1 is provided with an adjusting rod 4, the top end of the adjusting rod 4 is connected with a support plate 5, the top end of the support plate 5 is connected with a mounting block 6, a fixing pin 13 is assembled inside the mounting block 6, a spring 8 is sleeved on the surface of the fixing pin 13, a bidirectional threaded rod 9 is also assembled inside the mounting block 6, one end of the bidirectional threaded rod 9 is connected with a bearing 10, and a threaded sleeve 11 is threadedly connected to the surface of the bidirectional threaded rod 9.

[0022] Preferably in the embodiment: One end of the spring 8 is connected to the side wall of the fixed pin 13, and the other end of the spring 8 is connected to the opening on the inner wall of the mounting block 6. An elastic telescopic connection is formed between the fixed pin 13 and the mounting block 6 through the spring 8.

[0023] Preferably in the embodiment: The opposite threads on the surface of the bidirectional threaded rod 9 are symmetrical, and a rotational connection is formed between the bidirectional threaded rod 9 and the mounting block 6 through the bearing 10.

[0024] Preferably in the embodiment: The side wall of the threaded sleeve 11 close to the fixed pin 13 is connected to the fixed pin 13, and a threaded movement is formed between the fixed pin 13 and the bidirectional threaded rod 9 through the threaded sleeve 11.

[0025] Preferably in the embodiment: A docking hole is provided at the bottom end of the docking block 7, and a fixed connection is formed between the docking block 7 and the mounting block 6 through the fixed pin 13.

[0026] Preferably in the embodiment: A suction cup 12 is installed at the bottom end of the base 1, and the suction cup 12 is installed at the bottom end of the base 1 through screws.

[0027] In the embodiment, when the ophthalmoscope body 3 is connected to the base 1 for use, at this time, the base 1 is fixed to the ground by using the suction cup 12. Then, the box body 2 is taken out and the docking block 7 at the bottom end is brought close to the mounting block 6. Subsequently, the opening at the bottom end of the docking block 7 is inserted along the outer side wall of the mounting block 6. Then, the bidirectional threaded rod 9 is rotated in the forward direction, so that the bidirectional threaded rod 9 rotates inside the mounting block 6 along the inside of the bearing 10. Then, the threaded sleeves 11 move away from each other along the opposite threads on the surface of the bidirectional threaded rod 9, and the movement of the threaded sleeves 11 will drive the fixed pin 13 to move outwards from the inside of the mounting block 6. At the same time, the movement of the fixed pin 13 will squeeze the spring 8, and thus the spring 8 will be compressed and deformed. At this time, when the fixed pin 13 moves outwards from the inside of the mounting block 6, it will be stuck in the openings at the left and right ends of the docking block 7, thereby fixing the position of the docking block 7. At the same time, the fixed position of the docking block 7 will also fix the position of the box body 2, thereby completing the connection between the ophthalmoscope body 3 and the base 1. When it is necessary to adjust the position of the ophthalmoscope body 3, the height position of the ophthalmoscope body 3 can be adjusted through the adjusting rod 4, and then the patient's eyeball can be brought close to the ophthalmoscope body 3 for examination.

[0028] In another embodiment, if the ophthalmoscope body 3 and the base 1 are disassembled for use, at this time, the bidirectional threaded rod 9 is rotated reversely, so that the bidirectional threaded rod 9 rotates inside the mounting block 6 along the inside of the bearing 10. Then, the threaded sleeves 11 move closer to each other along the opposite threads on the surface of the bidirectional threaded rod 9. The movement of the threaded sleeves 11 will drive the fixing pins 13 to move inward from the outside of the mounting block 6. Thus, the fixing pins 13 are removed from the openings at the left and right ends of the docking block 7, and the connection between the fixing pins 13 and the docking block 7 is released. Subsequently, the box body 2 can be taken off from the top of the base 1. Then, the medical staff holds the box body 2 and brings the ophthalmoscope body 3 close to the eyes of the patient who is inconvenient to move for examination. When the fixing pins 13 move closer to each other, the extrusion force received by the spring 8 will decrease, and then the spring 8 will reset. The use of the spring 8 improves the stability of the movement of the fixing pins 13 and prevents movement deviation, which is inconvenient for back-and-forth movement inside the mounting block 6.

[0029] In summary, by using the fixing pins 13, it is convenient to disassemble and assemble the docking block 7 and the mounting block 6, so that the ophthalmoscope body 3 can be applicable to patients in different states. At the same time, when the medical staff holds and disassembles the ophthalmoscope body 3 for use, the situation that the stability of the medical staff holding the ophthalmoscope body 3 is reduced due to the weight of the base 1 is also reduced. Subsequently, the use of the suction cup 12 also improves the connection stability between the base 1 and the ground when the base 1 and the ophthalmoscope body 3 are used together, and improves the examination efficiency of the ophthalmoscope body 3 for the patient's eyes.

[0030] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
