[0024] As can be seen from the above description, the beneficial effect of the present invention is that the upper and lower frames 12 are quickly connected by the first and second engaging portions 111, 121, and the engaging block 13. Compared to conventional connection processes involving drilling and screwing, the mortise and tenon structure of the first and second engaging portions 111, 121, and the engaging block 13 can reduce the need for detailed processing of the frame 1, especially for frames 1 made of materials such as carbon crystal, which are strong and difficult to drill.

[0025] Furthermore, the first joint portion 111 of the upper lens frame 11 is provided at a position where it is connected to the lower lens frame 12 , and the second joint portion 121 of the lower lens frame 12 is provided at a position where it is connected to the upper lens frame 11 .

[0026] As can be seen from the above description, the design of the first joint portion 111 and the second joint portion 121 at the docking position of the upper frame 11 and the lower frame 12 can reduce the size design of the snap block 13, and the snap structure is arranged more compactly.

[0027] Furthermore, it also includes a lens 2, and the upper frame 11 and the lower frame 12 are respectively provided with a first mounting groove 112 and a second mounting groove 122, and the outer edge of the lens 2 is clamped in the first mounting groove 112 and the second mounting groove 122; the first joining portion 111 is provided in the first mounting groove 112, and the second joining portion 121 is provided in the second mounting groove 122.

[0028] As can be seen from the above description, by designing the first joint portion 111 and the second joint portion 121 in the first installation groove 112 and the second installation groove 122 respectively, the uneven appearance of the frame 1 can be avoided and the first joint portion 111 and the second joint portion 121 can be hidden.

[0030] From the above description, it can be seen that the mortise and tenon connection of the upper frame 11 and the lower frame 12 is realized by the engagement of the two ends of the snap block 13 with the first engagement groove 113 and the second engagement groove 123; at the same time, since the outer edge of the lens 2 will be engaged in the first installation groove 112 and the second installation groove 122 when assembled, the mortise and tenon connection structure of the snap block 13 and the first engagement part 111 and the second engagement part 121 can be further reinforced by the engagement of the lens 2.

[0031] Furthermore, the locking block 13 has a third mounting groove 132 on one side away from the first engaging portion 111 and the second engaging portion 121 , which is connected to the first mounting groove 112 and the second mounting groove 122 ; the outer edge of the lens 2 is locked in the first mounting groove 112 , the second mounting groove 122 and the third mounting groove 132 .

[0032] As can be seen from the above description, the third mounting groove 132 on the snap block 13 can be designed to cooperate with the first mounting groove 112 and the second mounting groove 122 to serve as a snap-fit ​​mounting position for the outer edge of the lens 2 .

[0033] Furthermore, a first docking protrusion 114 is provided on one end of the upper mirror frame 11 and the lower mirror frame 12 , and a first docking groove 124 is provided on the lower mirror frame 12 corresponding to the first docking protrusion 114 ; the first docking protrusion 114 is engaged with the first docking groove 124 .

[0035] Furthermore, it also includes temples 3 and connectors 4 , wherein the temples 3 are connected to the connectors 4 , and the connectors 4 are snap-fitted to the frame 1 .

[0036] As can be seen from the above description, by snapping the connector 4 into the frame 1 , the temple 3 can be quickly assembled on the frame 1 .

[0037] Furthermore, a snap-fitting groove 115 is concavely formed on the upper frame 11 , and one end of the connector 4 that is snap-fitted to the frame 1 is U-shaped, and one end of the U-shaped connector 4 is buckled into the snap-fitting groove 115 .

[0038] As can be seen from the above description, the connection between the connector 4 and the frame 1 is achieved by the snap connection between the snap connection groove 115 on the upper frame 11 and the U-shaped end of the connector 4 .

[0039] Furthermore, a first mounting groove 112 for clamping the lens 2 is provided on the inner edge of the upper frame 11, and the clamping groove 115 is formed by a concave portion of the first mounting groove 112.
