[0018] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will now be described with reference to the accompanying drawings.

[0019] As shown in Figures 1 to 8, the present invention provides an assembled binocular surgical magnifier comprising a substantially π-shaped fixed frame 1. The fixed frame 1 includes a bridge 2 for mounting optical lenses and extensions 14 extending outward from both ends of the bridge 2. The fixed frame 1 further includes two fixing rings 3 located at the other ends of the extensions 14 for mounting magnifying lens tubes 6. The fixing rings 3 are connected to the bridge 2 via the extensions 14 and extend to a position close to the wearer's interpupillary distance. As shown in Figure 4, the central axis of the fixing rings 3 and the longitudinal axis of the bridge 2 form different inward angles, i.e., visual axis angles, depending on the interpupillary distance and working distance. This is advantageous for achieving the effect of superimposing and fusing binocular images within a set working distance for users with the same interpupillary distance, depending on the user's interpupillary distance, such as a typical working distance of 300 mm, 400 mm, 450 mm, 500 mm, 550 mm, or 600 mm. The bridge 2 may be made of a material such as metal or resin, and has a nose rest 4. The bridge 2 has several fixing holes, which are used to fix temples, optical lenses 5, etc. with screws or snap fasteners.

[0020] The collapsible binocular surgical magnifier further includes a magnifying lens tube 6 detachably connected to the fixing ring 3. In this embodiment, the front end face of the magnifying lens tube 6 is a magnifying lens 7, and the rear end of the housing is preferably provided on the outside with a second thread 8 that matches the first thread provided on the fixing ring 3, thereby allowing the magnifying lens tube 6 to be detachably attached to the fixing frame 1 by screwing. Here, the first and second threads 8 may be female and male threads, respectively, or the first and second threads 8 may be male and female threads, respectively. The magnifying lens tube 6 can be connected to the fixing frame 1 by engagement or the like. The housing at the rear end of the magnifying lens tube 6 has an attachment portion 9. The attachment portion 9 forms a groove-like portion that can accommodate the magnifying lens tube 6 by partially extending the housing toward the rear end.

[0021] The corrective lens ring 10 is detachably attached to the mounting portion 9 at the rear end of the magnifying lens tube 6. The corrective lens ring 10 is used to mount a myopia lens 12 or a reading glasses lens 11, and the corresponding corrective lens ring 10 is arranged with corresponding specifications based on the myopia lens 12 or reading glasses lens 11. A seal ring groove is provided on the corrective lens ring 10, and the seal ring forms a seal between the corrective lens ring 13 and the mounting portion 9 of the magnifying lens tube 6. The corrective lens ring 10 is detachably attached to the mounting portion 9 at the rear end of the magnifying lens tube 6 by pressing the seal ring 13. Here, there may be at least two seal ring grooves, a myopia lens seal ring groove 23 corresponding to the corrective lens ring of the myopia lens and a reading glasses seal ring groove 24 corresponding to the corrective lens ring of the reading glasses lens. Because the myopic lens is thin, the myopic lens seal ring groove 23 is located closer to the outside, while the reading glasses lens is thicker, so the reading glasses seal ring groove 24 is located closer to the inside. In this way, the two seal ring grooves secure the corrective mirror ring. The myopic lens 12 or reading glasses lens 11 can be easily fixed to the corrective lens ring 10 by extrusion or UV adhesive according to the shape of the corrective lens ring 10 or the lens template. When replacement is required, the corrective lens ring 10 can be replaced or the lens can be removed. Therefore, the cooperation of the first screw thread 8 and the second screw thread 8 allows for the assembly and switching of lens barrels with the same working distance and different magnifications according to the wearer's actual needs. The corrective lens ring 10 also has a hole 25 that facilitates rotation to adjust the axial position of the lens.

[0022] 4 and 5, the structure after assembly of the fixed frame 1 and magnifying lens tube 6 is completed has a pitch indicated by D2 which is the interpupillary distance, and the pitch direction indicated by D1 which is the working distance focusing angle of the magnifying lens tube 6. Furthermore, the fixed ring 3 is inclined toward the wearer's body relative to the extension 14, and an obtuse angle a is formed between the outer surface of the fixed ring 3 and the extension 14, which allows the wearer to perform surgery or other procedures in a relatively comfortable position, preventing excessive head bending and neck fatigue.

[0023] The assembled binocular surgical magnifier may further include a wearing mechanism that is a framed structure or a frameless structure having temples. If the wearing mechanism is a frameless structure, the temples 15 are fixed by screws or snaps in pre-mounted fixing holes on the optical lens 5. If the wearing mechanism is a framed structure, the eyeglass frame 16 extends on both sides from the fixed frame 1, or the eyeglass frame 16 can be understood to be a part of the fixed frame 1, and the temples 17 are disposed on the eyeglass frame 16.

[0024] The wearing mechanism may be a head mount device including a head mount portion 22, a damping movable bracket 18, and a clamp 19. The head mount portion 22 is a wearable portion made of rubber and has a rigid support portion where its edge is placed over the head, and the damping movable bracket 18 is attached to the support portion. The damping movable bracket 18 is fixed to the head mount portion 22 and has three or more movable points, making it easy to adjust the overall position of the fixed frame 1. The clamp 19 is located at the end of the damping movable bracket 18 and can be attached to a fixing hole in the bridge 2 by screws or snap-fastening, allowing the fixed frame 1 to be detachably fixed by the clamp 19. A headlamp 20 is fixed to the damping movable holder 18 or the holder 1 and is located between the two optical lenses 5. The headlamp 20 can be fixed to the knob 21 of the clamp 19 via a headlamp clamp.

[0025] The above is a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention. In other words, all modifications and variations that fall within the scope of the present invention should be included within the scope of the present invention. [Explanation of symbols]
