[0029] Embodiment 2:

[0030] Different from embodiment 1, in addition to comprising the structural features of the preceding embodiments, in the specific embodiments of the utility model, as shown in Figure 1 , Figure 2 and Figure 3 , the rotating shaft connecting piece comprises a rotating groove 2 opened at one end of the flexible connecting piece, a through hole 3 penetrating the groove wall of the rotating groove 2 upward and downward, a screw 4 and a fixed cylinder 5 with a threaded hole, one side of the glasses frame 1 extends into the rotating groove 2 and the end part is provided with a circular hole penetrating upward and downward, and the glasses frame 1 is rotationally limited in the rotating groove 2 by cooperation of the screw 4 and the fixed cylinder 5.

[0031] The flexible connecting piece in the application is cylindrical at both ends and connected in the middle, and a plurality of triangular prism-shaped protrusions are further arranged in the middle, and the difference from the prior art is that the shape of the cylindrical at both ends is to increase the size of both ends to improve the overall stress strength, and the glasses frame 1 is the upper part of the side wall extending into the rotating groove 2, and the glasses frame 1 and the flexible connecting piece usually only need to rotate about 90 degrees, so the rotating groove 2 can be clearly seen from Figure 2 , which is opened at the end of the cylindrical flexible connecting piece, when the glasses leg is in the open state, the glasses frame 1 is located at the right side of the rotating groove 2 of the flexible connecting piece in Figure 2 , and when the glasses leg is turned to the front of the glasses frame 1, the glasses frame 1 is rotated to the front of the rotating groove 2, as shown in Figure 3 , the screw 4 and the fixed cylinder 5 with a threaded hole structure, when installing, first extend one side of the glasses frame 1 into the rotating groove 2, put the fixed cylinder 5 into the upper through hole 3 first, then pass the screw 4 from below to above into the lower through hole 3, and screw into the threaded hole of the fixed cylinder 5, at this time, the relative installation between the flexible connecting piece and the glasses frame 1 is completed, and the flexible connecting piece can be rotated after installation.

[0032] In the specific embodiments of the utility model, the end of the fixed cylinder 5 is connected with a first special-shaped block 6, a first special-shaped groove 7 for clamping the first special-shaped block 6 is arranged on the flexible connecting piece, and the groove bottom of the first special-shaped groove 7 is communicated with the through hole 3.

[0033] In this embodiment, the first irregular block 6 connected to the end of the fixed cylinder 5 is used to cooperate with the first irregular groove 7 on the flexible connector. With the cooperation of the two, the fixed cylinder 5 will not rotate when inserted into the through hole 3, which further improves the stability of the structure.

[0034] In a specific embodiment of this utility model, the first irregular block 6 is shaped like a central cylinder, and six semi-cylinders with semi-circular cross-sections are arranged equidistantly along the circumference on the central cylinder, so that the irregular block 6 is shaped like a plum blossom.

[0035] To further prevent the rotation of the fixed cylinder 5 and screw 4 when the flexible connector and the eyeglass frame 1 rotate, thereby affecting the installation stability, the shape of the first irregular block 6 is set to be plum blossom-like. After the first irregular block 6 is inserted into the first irregular groove 7, the fixed cylinder 5 will not rotate.

[0036] Example 3:

[0037] The difference from Embodiment 2 is that, in addition to including the structural features of the aforementioned embodiments, in this specific embodiment of the utility model, such as... Figures 1-6 As shown, the insertion fastener includes an eyeglass temple insertion hole 11 at the end of the eyeglass temple, an insertion groove 12 formed at one end of the flexible connector for the eyeglass temple end to be inserted, a first hole 13 and a second hole 14 penetrating the groove wall of the insertion groove 12 from left to right, an insertion block 15, and a fixing pin 16. When the eyeglass temple end is inserted into the insertion groove 12, the insertion block 15 passes through the first hole 13 and is inserted into the eyeglass temple insertion hole 11. The insertion block 15 is provided with a horizontally penetrating circular hole 17, and one end of the fixing pin 16 passes through the second hole 14 and is inserted into the circular hole 17.

[0038] The temple and the flexible connector are installed by a plug-in fastener, mainly to improve connection stability and avoid relative rotation. During installation, the end of the temple is inserted into the insertion slot 12. Then, the plug-in block 15 is inserted into the temple insertion hole 11 after passing through the first hole 13. Finally, one end of the fixing pin 16 is inserted into the circular hole 17 of the plug-in block 15 after passing through the second hole 14. Since the flexible connector is made of flexible material, if a simple plug-in fastener structure is used directly, the fastening effect will be far inferior to the technical solution disclosed in this application.

[0039] In a specific embodiment of this utility model, the plug-in block 15 is in the shape of a triangular prism, and the first hole 13 is configured as a triangular prism-shaped hole adapted to the plug-in block 15.

[0040] The triangular prism-shaped plug 15 is inserted into the first hole 13, and then into the eyeglass temple insertion hole 11 of the eyeglass temple. The triangular structure prevents the plug 15 from rotating relative to the flexible connector, thereby limiting the eyeglass temple.

[0041] In a specific embodiment of this utility model, the end of the plug block 15 away from the temple hole 11 is connected to a second irregular block 18, and a second irregular groove 19 is provided at one end of the first hole 13 and on the flexible connector. The shape of the second irregular block 18 is adapted to the shape of the second irregular groove 19.

[0042] Based on the triangular prism-shaped insertion block 15, this embodiment further connects a second irregularly shaped block 18 to the end of the insertion block 15 away from the temple insertion hole 11, and a second irregularly shaped groove 19 is provided at one end of the first hole 13 and on the flexible connector, such as... Figure 1 As shown, after installation, the plug block 15 is inserted into the first hole 13 and the temple hole 11. Then, one end of the fixing pin 16 passes through the second hole 14 from the other side and is inserted into the circular hole 17, and presses against the second irregular block 18. In this way, the fixing pin 16, together with the plug block 15 and the second irregular block 18, plays a limiting role, while improving the overall installation stability.

[0043] In a specific embodiment of this utility model, the second irregular block 18 is shaped like a central cylinder, and six semi-cylinders with semi-circular cross-sections are arranged equidistantly along the circumference on the central cylinder, so that the second irregular block 18 is shaped like a plum blossom.

[0044] To further improve the rotational limiting strength of the second irregular block 18, its shape is set to be plum blossom-like, and the shape of the second irregular groove 19 is adapted to the shape of the second irregular block 18.

[0045] like Figure 5 As shown, in this embodiment, the fixing pin 16 is T-shaped as a whole. In order to improve the stability of the fixing pin 16 when inserted into the second hole 14 and the circular hole 17 and to prevent it from retracting outward, a multi-segment frustum structure is provided in the cylindrical part of its T-shape. The multi-segment frustum structure is distributed sequentially from bottom to top, and the smaller side of the frustum structure is at the bottom. During installation, it is convenient for the lower end of the fixing pin 16 to be inserted into the second hole 14 and the circular hole 17 sequentially. However, when pulling the fixing pin 16 outward, a greater force needs to be applied.

[0046] It should be noted that, in the present document, the terms "comprises", "comprising", or any other variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but can also include other elements not expressly listed or inherent to such process, method, article, or apparatus.
