The folding mechanism 3 is located inside the C-shaped beam 1 and includes a rotating rod 302 and a movable plate 303. Two sets of rotating rods 302 are rotatably mounted on the bottom and top inner sides of the C-shaped beam 1. The outer walls of the two sets of rotating rods 302 are respectively fixedly connected to the inside of a movable plate 303, and the two sets of movable plates 303 are respectively fixedly connected to the outer walls of a set of lens frames 2. The adjustment mechanism 4 is located outside the C-shaped beam 1 and includes main temples 401 and temple sleeves 403. A set of main temples 401 is hinged to the outer walls of the two sets of lens frames 2, and temple sleeves 403 are slidably mounted on the outer walls of the main temples 401. A set of nose pads 7 are fixedly mounted on the rear side of the lens frames 2.

[0023] Secondly, the folding mechanism 3 also includes positioning holes 301 and locking blocks 304. Two sets of positioning holes 301 are provided on the front side of the C-shaped crossbeam 1, and a set of locking blocks 304 are fixedly installed on the front side of the two sets of movable plates 303 respectively. The locking blocks 304 are locked to the inner wall of the positioning holes 301, which improves the structure of the eyeglass frame, so that the temples can still be folded between the outer frame of the lens 2 after being folded, reducing the space occupied by the eyeglass frame after folding, making it easier for users to carry and store, and improving the usability and practicality of the device.

[0024] Furthermore, the adjustment mechanism 4 also includes limiting holes 402, hollow blocks 404, separators 405, connecting rods 406, and springs 407. Multiple sets of limiting holes 402 are provided on one side of the main temple 401. A hollow block 404 is fixedly installed on one side of the temple sleeve 403.

The mounting blocks 5 are then inserted into the temple sleeve rod 403 to complete the installation of the silicone ear hook 6. By pulling the pull ring outward, the insertion rod 406 is pulled, causing the separator 405 to move within the hollow block 404, compressing the spring 407. To retract the lens, move the insertion rod 406 out of the limiting hole 402, allowing the temple sleeve rod 403 to slide freely on the main temple 401. Adjust the position of the silicone ear hook 6 according to the user's needs, then release the insertion rod 406. Under the elastic action of the spring 407, the separator 405 is reset, which in turn causes the insertion rod 406 to re-insert into the limiting hole 402, limiting the temple sleeve rod 403. When not in use, completely retract the temple sleeve rod 403, and then fold the lens frame 2 for easy storage.
