[0002] In the field of precision instrument repair, especially in the watch repair industry, due to the tiny size and complex structure of watch parts, repair personnel need to use high-precision magnifying glasses to assist in operations such as inspection and assembly. Head-mounted magnifying glasses, because they free up the hands and provide a flexible viewing angle, have become one of the commonly used tools for watch repairers.

[0003] Existing head-mounted watch repair magnifying glasses have several problems in practical use. On the one hand, their lenses lack effective protective structures, allowing dust and debris to easily enter the lens barrel when not in use. The lens surface is also easily scratched or contaminated with dust, leading to decreased lens clarity and affecting the accuracy of subsequent repair work. On the other hand, the illumination lamps of such magnifying glasses are usually fixedly installed. When the lamp is damaged, repair personnel need to disassemble multiple parts with tools to replace it, which is a cumbersome and time-consuming process. This can cause repair work to be interrupted due to lamp failure, greatly reducing the efficiency and reliability of the magnifying glass. To address these technical problems, this application proposes a head-mounted watch repair magnifying glass. Summary of the Invention

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Referring to Figures 1-3, one embodiment of this utility model is provided: a head-mounted watch repair magnifying glass, including a frame 1, a lens barrel 2 fixedly connected to the bottom side of the frame 1, a fixing ring 3 fixedly connected to the rear end of the lens barrel 2, a collar 4 provided on the outer wall of the lens barrel 2, a lens cap 6 connected to the front side of the lens barrel 2 via a torsion spring, a limiting plate 7 fixedly connected to the outer wall of the lens cap 6, a groove 5 opened on the inner wall of the collar 4, the limiting plate 7 being disposed inside the groove 5, and the end of the spring 8 facing the fixing ring 3... The outer wall is connected, and the other end of the spring 8 is connected to the outer wall of the collar 4 for opening the lens cap 6. The outer wall of the fixing ring 3 is fixedly connected to the mounting block 9, and the slide rod 14 is slidably connected to the inner wall of the mounting block 9. One end of the slide rod 14 is fixedly connected to the top block 15. The outer wall of the fixing block 10 is fixedly connected to the top block 13. The outer wall of the slide rod 14 is provided with the spring 16. The outer wall of the fixing block 10 is provided with the illumination lamp 11. The inner wall of the lens barrel 2 is provided with the lens 12, and the outer wall of the lens barrel 2 is provided with the spring 8.

[0024] Specifically, when using the magnifying glass, first, by moving the limiting plate 7, the lens cap 6 is opened from the front of the lens barrel 2. Next, the collar 4 is moved, and the spring 8 on the outer wall of the lens barrel 2 engages the slot 5 on the front of the collar 4 with the limiting plate 7, thus securing the two opened lens caps 6. When the magnifying glass is not in use, to protect the lens 12 inside the lens barrel 2, the collar 4 is moved backward to disengage the slot 5 from the limiting plate 7. Then, with the help of the torsion spring, the lens cap 6 is reattached to the front of the lens barrel 2 to prevent damage to the lens 12 from foreign objects and to prevent dust from settling on the lens 12 surface, affecting future use. If the illumination lamp 11 malfunctions during use, the sliding rod 14 can be pulled to disengage the top block 15 from the top block 13, allowing the fixing block 10 to be removed from the inner wall of the mounting block 9. Then, the new fixing block 10 and illumination lamp 11 are assembled, and the top block 13 is inserted into the inner wall of the mounting block 9. As the top block 13 is inserted, its curved surface contacts the curved surface of the top block 15, compressing the spring 16 on the outer wall of the slide rod 14. When the top block 13 is inserted further, the compressed spring 16 will reset and lock the top block 15 onto the outer wall of the top block 13, thus completing the installation of the fixing block 10 and the lighting lamp 11.

[0025] Referring to Figures 1-3, top block 13 is set on the outer wall of top block 2 15, and a circular limiting plate is fixedly connected to the other end of the slide rod 14. One end of spring 2 16 facing top block 2 15 is connected to the outer wall of top block 2 15, and the other end of spring 2 16 is connected to the inner wall of mounting block 9. The rear silicone pad of the frame 1.

[0026] Specifically, the top block 13 is set on the outer wall of the top block 2 15 to achieve the engagement between the top block 13 and the top block 2 15, thereby enabling the installation of the lighting lamp 11. The spring 2 16 controls the sliding of the top block 2 15 on the inner wall of the mounting block 9 through its compression and reset. The silicone pad can increase the fit with the head, reduce pressure and prevent slippage, and ensure stable use.

[0027] Working principle: In use, the lens cap 6 is opened from the front of the lens barrel 2 by moving the limiting plate 7. Then, the collar 4 is moved, and the spring 8 on the outer wall of the lens barrel 2 locks the groove 5 on the front of the collar 4 into the outer wall of the limiting plate 7, thus fixing the two opened lens caps 6 together. When the magnifying glass is not in use, to protect the lens 12 inside the lens barrel 2, simply move the collar 4 backward to disengage the groove 5 from the limiting plate 7. Then, the torsion spring closes the lens cap 6 on the front of the lens barrel 2, thus protecting the lens 12 inside the lens barrel 2 from damage by foreign objects and preventing dust from settling on the outer wall of the lens 12. To ensure the next use, if the lighting lamp 11 is damaged, the top block 15 and the top block 13 can be separated by pulling the slide rod 14, and the fixing block 10 can be pulled out from the inner wall of the mounting block 9. Then, the new fixing block 10 and the lighting lamp 11 can be directly inserted into the inner wall of the mounting block 9. Through the contact between the curved surface of the top block 13 and the curved surface of the top block 15, the spring 16 on the outer wall of the slide rod 14 is compressed. When the top block 13 is inserted deeper, the compressed spring 16 will reset and lock the top block 15 onto the outer wall of the top block 13, thereby completing the installation of the fixing block 10 and the lighting lamp 11.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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 make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
