[0024] Specifically, the structure in which the temple 2 is hinged on the pile head 11 and the gear 3 is fixedly connected to the temple 2 is as follows: the pile head 11 is fixedly connected to a hinge block 12, a hinge groove 21 matching the hinge block 12 is provided on the inner side surface of the end of the temple 2, a prismatic connecting pile 31 is formed on the upper end surface of the gear 3, a connecting hole 22 matching the connecting pile 31 is provided on the bottom wall of the hinge groove 21, a nut hole 32 is provided on the lower end surface of the gear 3, a connecting nut 5 matching the nut hole 32 is provided in the nut hole 32, a first bolt hole 23 is provided on the top wall of the hinge groove 21, a second bolt hole 121 is provided on the hinge block 12, a third bolt hole 33 is provided on the connecting pile 31, and the connecting The pile 31 is inserted into the connecting hole 22 so that the third bolt hole 33 is aligned with the first bolt hole 23, and the hinge block 12 is inserted into the hinge groove 21 so that the second bolt hole 121 is aligned with the first bolt hole 23. The connecting bolt 6 provided in the first bolt hole 23 passes through the second bolt hole 121 and the third bolt hole 33 in sequence and is screwed onto the connecting nut 5. The connecting bolt 6 cooperates with the connecting nut 5 to hinge the temple 2 on the hinge block 12 while tightening the gear 3 to keep the connecting pile 31 in the connecting hole 22. The cooperation between the connecting pile 31 and the connecting hole 22 enables the gear 3 to rotate with the swing of the temple 2. The above structure facilitates the disassembly and assembly of the gear 3, and facilitates the assembly of the glasses while facilitating the maintenance of the gear 3.

[0025] In the above embodiment, when the two temples 2 are opened and the glasses are worn, the temples 2 drive the gear 3 to rotate, and the gear 3 drives the support rod 4 to slide backward in the first sliding hole 111 by cooperating with the transmission tooth 41, so that the front end of the support rod 4 is retracted in the first sliding hole 111 and does not protrude from the end face of the frame 1, so that the overall appearance of the glasses is the same as that of ordinary glasses, ensuring the beauty of the overall appearance of the glasses without affecting the normal wearing of the glasses, and when the two temples 2 are closed, the temples 2 drive the gear 3 to rotate, and the gear 3 drives the support rod 4 to slide forward in the first sliding hole 111 by cooperating with the transmission tooth 41, so that the front end of the support rod 4 protrudes out of the first sliding hole 111. 11 protrudes from the front end surface of the frame 1. At this time, when the wearer places the front end surface of the frame 1 on the table with the front end surface facing downward, the front end of the support rod 4 is against the table surface to lift the frame 1, so that a certain gap is formed between the front end surface of the frame 1 and the table surface, and a certain gap is formed between the lens arranged in the frame 1 and the table surface, so that direct contact between the lens and the table surface in this case is avoided, thereby preventing the lens from being scratched.

When the temple 2 is opened and the support rod 4 is driven by the gear 3 to slide backward in the first sliding hole 111 and the temple 2 is fully opened, the limiting block 42 abuts against the limiting step 112, limiting the sliding of the support rod 4 in the first sliding hole 111, thereby ensuring the stability of the support rod 4 when sliding in the first sliding hole 111, and after the limiting block 42 abuts against the limiting step 112, the first sliding hole 111 will be covered, so that the appearance of the front end face of the frame 1 remains intact, thereby ensuring the overall aesthetics of the glasses.

[0027] Preferably, a limiting ridge 43 is formed on the upper end surface and the lower end surface along the sliding direction of the support rod 4, and a limiting groove 113 matching the limiting ridge 43 is formed on the top wall and the bottom wall of the first sliding hole 111, and the limiting ridge 43 is maintained in the limiting groove 113. When the support rod 4 slides in the first sliding hole 111, the limiting ridge 43 slides in the limiting groove 113. The limiting ridge 43 cooperates with the limiting groove 113 to limit the sliding of the support rod 4 in the first sliding hole 111, so that the support rod 4 can only slide in the first sliding hole 111 along the front and rear directions, thereby ensuring the stability of the support rod 4 when sliding, and ensuring that the transmission tooth 41 on the support rod 4 can stably mesh with the gear 3 to achieve transmission.

[0028] Preferably, the front end of the limit block 42 is arc-shaped, which improves the aesthetics of the limit block 42 and ensures the overall aesthetics of the glasses, while enabling the limit block 42 to rest more stably on the table surface to prevent the lenses from being scratched.

[0029] Furthermore, the pile head 11 is provided with a second sliding hole 114 which is connected to the first sliding hole 111 and whose port faces the transmission tooth 41. A limiting push rod 7 with an arc-shaped end is passed through the second sliding hole 114. A limiting spring 8 acting on the limiting push rod 7 is arranged in the pile head 11. Under the action of the limiting spring 8, the limiting push rod 7 extends out of the second sliding hole 114 and is inserted into the teeth of the transmission tooth 41.

[0030] Specifically, the structure in which the limit spring 8 acts on the limit push rod 7 is as follows: a spring hole 115 is provided in the pile head 11, which is connected to the second sliding hole 114 and has a larger aperture than the second sliding hole 114; the spring hole 115 passes through the pile head 11 to the side away from the second sliding hole 114; a limit portion 71 is formed at the end of the limit push rod 7, which matches the spring hole 115 and is disposed in the spring hole 115; the limit spring 8 is disposed in the spring hole 115; a limit bolt 9 is screwed on the end of the spring hole 115, which is tightly against the limit spring 8 and makes the limit spring 8 tightly against the limit portion 71; through the above structure, the transfer operation of the limit spring 8 and the limit push rod 7 is facilitated, and the maintenance of the limit spring 8 and the limit push rod 7 is facilitated.

[0031] In the above preferred embodiment, when the support rod 4 slides in the first sliding hole 111, the limit push rod 7 is pushed back and forth so that the end of the limit push rod 7 is stuck between the teeth of the transmission tooth 41 at different positions, and damping is applied to the sliding of the support rod 4 in the first sliding hole 111. When the glasses are fully opened or closed, the damping applied by the limit push rod 7 to the sliding of the support rod 4 makes the support rod 4 more stably maintained in the position retracted into the first sliding hole 111 or extended out of the first sliding hole 111, so that the support rod 4 plays a more stable supporting role when supporting and lifting the frame 1, ensuring the realization of the function of preventing the lens from being scratched, and when the support rod 4 is stably maintained at a certain position by the action of the limit push rod 7, the support rod 4 also makes the cooperation between the transmission tooth 41 and the gear 3 so that the temple 2 can be more stably maintained in the open or closed state, thereby facilitating the wearing and use of the glasses.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
