When the user moves quickly, the magnetic adsorption force restricts the insert blocks 21 from sliding upward, preventing them from falling out of the insert grooves 11, and the inner walls of the insert grooves 11 restrict the insert blocks 21 from moving horizontally, thereby improving the horizontal connection strength of the sunglass lenses 2 to the frame 1 and preventing the sunglass lenses 2 from easily falling out of the frame 1 when the user moves, improving the user experience.

[0022] Furthermore, the first insertion groove 12 opens toward the inside of the end piece 13 of the frame 1, thereby hiding the magnet 31 and preventing the magnet 31 from being exposed and damaging the neatness of the surface of the eyeglasses. The second insertion groove 22 is opened on one side of the insertion block 21 corresponding to the first insertion groove 12. When the insertion block 21 is inserted into the insertion groove 11, the magnet 31 and the magnetically attractive part 32 are attracted to each other in the horizontal direction, further improving the restraining force of the magnetic attraction when the insertion block 21 moves upward and comes out of the insertion groove 11.

[0023] Specifically, the inside of the end piece 13 refers to the side of the end piece 13 that faces the user's face when wearing the glasses.

[0024] Furthermore, a connecting beam 4 is provided at the upper end of the sunglass lens 2 along its length, two insert blocks 21 are provided at both ends of the connecting beam 4, a positioning mechanism is provided on the connecting beam 4, the connecting beam 4 is hinged to the upper end of the sunglass lens 2 by the positioning mechanism, and the sunglass lens 2 rotates around the connecting beam 4 and is stopped by the positioning mechanism.

[0026] Further, the positioning mechanism includes a stopper block 5, an adapter sleeve 6, a positioning block 7, and an elastic element 8, the stopper block 5, the adapter sleeve 6, and the positioning block 7 are arranged on the connecting beam 4 in this order along the length direction of the connecting beam 4, the stopper block 5 and the positioning block 7 are both fixedly connected to the connecting beam 4, the adapter sleeve 6 is rotatably connected to the connecting beam 4 and can slide along the connecting beam 4, the upper end of the sunglass lens 2 is fixedly connected to the adapter sleeve 6, the adapter sleeve 6 and the positioning block 7 are both provided with meshing teeth 61 along the circumferential direction at adjacent ends, the elastic element 8 is arranged between the adapter sleeve 6 and the stopper block 5, one end of the elastic element 8 is connected to the stopper block 5, and the other end of the elastic element 8 is connected to the adapter sleeve 6, the elastic element 8 drives the adapter sleeve 6 to slide and abut against the positioning block 7, thereby meshing the respective meshing teeth 61. When the user rotates the sunglass lenses 2, the adapter sleeve 6 also rotates, causing the interlocking teeth 61 at the end of the adapter sleeve 6 to slide along the slope of the interlocking teeth 61 at the end of the positioning block 7. Due to the interaction of each interlocking tooth 61, the adapter sleeve 6 slides a certain distance toward the stopper block 5. At this time, the elastic part 8 is pressed against the end of the adapter sleeve 6, deformed, and stores energy. When the user stops rotating the sunglass lenses 2, the elastic part 8 releases the energy and restores, causing the adapter sleeve 6 to move and slide back to its original state, causing each interlocking tooth 61 to interlock again, thereby restricting the rotation of the adapter sleeve 6. After the sunglass lenses 2 have rotated, they are stopped and fixed.

[0027] Furthermore, the connecting beam 4 consists of a mounting shaft 41 and two connecting arms 42 fixedly connected to both ends of the mounting shaft 41, the diameter of the mounting shaft 41 is smaller than the diameter of the connecting arms 42, the stopper block 5, adapter sleeve 6 and positioning block 7 are provided on the mounting shaft 41 in this order along the length of the mounting shaft 41, the stopper block 5 and positioning block 7 are both fixedly connected to the mounting shaft 41, the adapter sleeve 6 is rotatably connected to the mounting shaft 41 and can slide along the mounting shaft 41, and the two insert blocks 21 are respectively provided on the two connecting arms 42.

[0029] Furthermore, an accommodating chamber 62 is provided within the adapter sleeve 6, opening axially toward the stopper block 5. One end of the spring is placed within the accommodating chamber 62 and abuts against the bottom wall of the accommodating chamber 62, thereby allowing the inner wall of the accommodating chamber 62 to support the spring, improving the accuracy and stability of the spring installation.

[0030] The positioning mechanism further includes an integrally molded T-shaped piece 9, which is made of metal and consists of a long piece 91 and a protrusion 92 protruding from one side of the center of the long piece 91, the long pieces 91 being arranged in the same direction on the outside of the adapter sleeve 6 and the protrusion 92 being fixedly connected to the side wall of the adapter sleeve 6 by welding, and both ends of the long piece 91 being arranged on the same side with vertical insertion shafts 93, and two insertion holes 23 for inserting the insertion shafts 93 are correspondingly arranged at the upper end of the sunglass lens 2. A set screw 25 is inserted into each insertion hole 23. To install, simply insert the insertion shafts 93 into the corresponding insertion holes 23 of the sunglass lens 2, and the sunglass lens 2 and the T-shaped piece 9 are connected via the two insertion shafts 93, thereby fixing the sunglass lens 2 to the adapter sleeve 6.

[0031] Furthermore, a notch 24 is opened at the upper end of the sunglass lens 2 for engaging the long piece 91, and when the insertion shaft 93 is inserted into the corresponding insertion hole 23, the long piece 91 engages in the notch 24, making the long piece 91 flush with the upper end of the sunglass lens 2, improving the neatness of the appearance and improving the connection strength of the long piece 91 to the upper end of the sunglass lens 2.

[0032] Furthermore, both the connecting beam 4 and the sunglass lenses 2 are made of metal or plastic material, which reduces the weight of both and reduces the load on the bridge of the nose when the user is wearing the sunglass lenses 2.
