[0025] In the specific implementation process, as Figures 1 - 6 shown, a spectacle frame adjustment device for a trial frame includes two spectacle frames 1. Insertion mechanisms are fixedly arranged on one side of each of the two spectacle frames 1. An interpupillary distance adjustment device is arranged between the two spectacle frames 1. The bottom of the interpupillary distance adjustment device is fixedly connected with a fixed frame 2. Two nose pads 29 are slidably arranged in the fixed frame 2. A movable assembly for adjusting the distance between the two nose pads 29 is arranged in the fixed frame 2. On the opposite sides of the two spectacle frames 1, two fixing plates 3 are respectively fixedly connected. On one side of each of the two fixing plates 3, an earpiece adjustment mechanism is detachably connected;

[0026] The interpupillary distance adjusting device includes a mounting frame 4, a driving member, a first threaded rod 5 and two movable frames 6. The two movable frames 6 are arranged oppositely, and the sides of the two movable frames 6 away from each other are respectively fixedly connected to the side walls of the two spectacle frames 1. The outer side walls of the two movable frames 6 are matched with the inner side wall of the mounting frame 4. Chutes 7 are opened on the upper sides of the two movable frames 6, and the chutes 7 are matched with the blocks 8 opened on the upper side of the inner wall of the mounting frame 4. Two threads with opposite directions are respectively opened on the first threaded rod 5. The first threaded rod 5 is respectively threadedly connected to one side of the two movable frames 6. The driving member for driving the first threaded rod 5 to rotate is arranged in the mounting frame 4. The driving member includes a first bevel gear 9, a second bevel gear 10, a first rotating rod 11 and a first knob 12. The first bevel gear 9 is fixedly connected to the first threaded rod 5. The second bevel gear 10 is meshed with the first bevel gear 9. The upper end of the second bevel gear 10 is fixedly provided with a first rotating rod 11. The upper end of the first rotating rod 11 movably penetrates through the mounting frame 4 and is fixedly connected to the bottom of the first knob 12. If it is necessary to adjust the distance between the two spectacle frames 1 to meet the user's interpupillary distance, the first knob 12 can be rotated. The rotation of the first knob 12 drives the first rotating rod 11 to rotate. The first rotating rod 11 drives the second bevel gear 10 to rotate. Since the second bevel gear 10 is meshed with the first bevel gear 9, the first bevel gear 9 will rotate accordingly, and then drive the first threaded rod 5 to rotate. The two threads with opposite directions on the first threaded rod 5 will simultaneously drive the two movable frames 6 to move towards or away from each other, thereby changing the distance between the two spectacle frames 1;

[0027] The movable assembly includes a second threaded rod 13, a third bevel gear 14, a fourth bevel gear 15, a second knob 16 and two connecting rods 17. The two ends of the second threaded rod 13 are respectively rotatably connected to the inner walls on both sides of the mounting cavity opened in the fixed frame 2. Two threads with opposite directions are respectively opened on the second threaded rod 13. The two connecting rods 17 are arranged oppositely and are both threadedly connected to the second threaded rod 13. The outer side walls of one ends of the two connecting rods 17 are matched with the inner wall of the fixed frame 2. Nasal pads 29 are fixedly connected to one ends of the two connecting rods 17. The third bevel gear 14 is fixedly connected to the threaded rod. The fourth bevel gear 15 is meshed with the third bevel gear 14. The bottom end of the fourth bevel gear 15 is fixedly connected to a second rotating rod 18. The bottom end of the second rotating rod 18 movably penetrates through the fixed frame 2 and is fixedly connected to the upper end of the second knob 16. When it is necessary to adjust the distance between the nasal pads 29, only the second knob 16 needs to be rotated, and the second threaded rod 13 is driven to rotate through the second rotating rod 18, the fourth bevel gear 15 and the third bevel gear 14. Since the two threads on the second threaded rod 13 have opposite directions, the two connecting rods 17 will drive the nasal pad seats to move relative to each other, thereby changing the distance between the nasal pads 29;

[0028] The inserting sheet mechanism includes an inserting sheet frame 19, and a plurality of slots 20 for inserting lenses are formed in the inserting sheet frame 19;

[0029] The earplug adjusting mechanism includes a connecting block 21, a fixing rod 22 and a movable rod 23. A first mounting hole is formed on one side of the connecting block 21. The first mounting hole matches the second mounting hole formed on the fixing plate 3. A bolt 24 is inserted into the first mounting hole and the second mounting hole. When the earplug adjusting mechanism is damaged, only need to loosen the bolt 24, and then the connecting block 21 can be removed from the fixing plate 3 to realize the disassembly of the earplug adjusting mechanism, which is convenient for replacement or maintenance. One end of the fixing rod 22 is fixedly connected to one side of the connecting block 21. A through groove is formed on one side of the fixing rod 22. The inner side wall of the through groove matches the outer side wall of the movable rod 23. First through holes 27 are formed on the upper and lower inner walls of the fixing rod 22. A plurality of second through holes 28 are equidistantly formed on the side wall of the movable rod 23. One end of the movable rod 23 is in a hook shape. A magnet 25 is fixedly connected to the bottom of the first through hole 27. A magnetic rod 26 is inserted into the first through hole 27 and one of the second through holes 28. The magnet 25 and the magnetic rod 26 are magnetically attracted to each other. According to needs, the magnetic rod 26 can be pulled out from the current first through hole 27 and second through hole 28, and then inserted into the second through holes 28 at different positions on the movable rod 23. Since the magnet 25 is fixed to the bottom of the first through hole 27, and the magnet 25 and the magnetic rod 26 are magnetically attracted to each other, the magnetic rod 26 can be stably held at the selected position, thereby fixing the movable rod 23 to quickly adjust the length of the earplug.

[0030] The above are only the embodiments of the present invention, and thus do not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present invention.
