[0060] In another embodiment, if Figure 6 and Figure 7 As shown, the side of the adapter 5 adjacent to the first positioning surface 51 is an arc structure, and the length and width of the second positioning surface 131 are correspondingly larger than the length and width of the first positioning surface 51. Specifically, it is ensured that the adapter 5 can be completely placed in the hook axis position 17 formed by the second hook portion 13 and the first hook portion 10. The outer contour of the adapter 5 is composed of a cylindrical structure cutting a side surface to form the first positioning surface 51, and then the corresponding connecting shaft 7, slotted position 6 and limit plug 8 are set. Furthermore, the structure is simple and compact, easy to install, with few exposed parts and high firmness.

[0065] In another embodiment, a pair of glasses includes a glasses frame having a frame 18 and lenses mounted on the frame 18, wherein the glasses frame is the glasses frame described above.

[0066] The solution of the utility model adopts a screw-free elastic hook 9 eyeglass leg 12 structure, which is specifically combined with the lever principle: Figure 5 As shown, the elastic hook 9 passes the hook top 11 through the hook top opening 16 of the eyeglass leg 12 at a vertical angle of 90°, and then the elastic hook 9 rotates 90° clockwise (i.e., the dotted arrow) and passes through the insertion opening 4 of the eyeglass leg 12, so that the elastic hook 9 and the eyeglass leg 12 are at the same horizontal angle of 180°. At this time, the temple positioning column 15 between the insertion opening 4 and the hook top opening 16 can play a positioning role to clamp the hook top 11 and prevent it from moving forward and backward. When the elastic hook 9 and the eyeglass leg 12 are combined at 180°, the hook top 11 supports the eyeglass leg 12 to form one of the pressure points of the lever principle. At this time, the elastic hook 9 and the eyeglass leg 12 are combined into a combination. Figure 6 and Fig. 9 As shown, the adapter 5 is engaged with the insert edge 3 of the pile head 1 through the slot 6 and is inserted into the pile head 1 to form another assembly. Figure 5 and Figure 7As shown, the elastic hook 9 is pressed clockwise and the temple 12 is pressed counterclockwise in their respective directions at the same time, and the combination of the elastic hook 9 and the temple can make the hook axis position 17 open a certain opening. At this time, the combination of the pile head 1 and the adapter 5 is pushed into the hook axis position 17 through the opening of the hook axis position 17, and the first hook portion 10 is hooked on the connecting shaft 7, so that the combination of the pile head 1 and the adapter 5 is installed on the combination of the elastic hook 9 and the temple 12. The second hook portion 13 wraps around the limiting insert 8, which serves as another pressure point of the lever principle for positioning and forming the opening and closing of the temple 12. The first hook portion 10 on the elastic hook 9 is hooked into the connecting shaft 7 of the adapter 5 and the limiting avoidance opening 2 on the pile head 1 at the same time. At this time, the first hook 10 and the second hook 13 form an upper and lower bite to hook the pile head 1 and / or the adapter 5, and the pile head positioning column 4 between the limit avoidance opening 2 and the limit insertion opening 31 will be hooked because the second hook 13 passes through the limit avoidance opening 2, so as to form a whole set of structures with the combination of the first hook 10 and the second hook 13 hooking the pile head 1 and the adapter 5. This structural design is ingenious and concise, saves production costs, changes the traditional glasses legs 12 that need welding, hinges, and screws, and at the same time enables the temples to have a certain external elastic force, making the glasses more comfortable to wear.
