The main frame 11 and the two side frames 12 are integrally formed, so that the manufacturing cost is reduced.

In this embodiment, the main frame 11 and the inner peripheral wall enclosed by the two side frames 12 have a chute 14, the limiting groove 13 is opened in the chute 14, the lens 2 is slidably disposed in the chute 14, the lens 2 is guided by the chute 14, and the lens 2 can be rapidly mounted on the frame 1.

As shown in fig. 3, preferably, the limiting groove 13 is opened on the side wall of the sliding groove 14, the protrusion 21 is disposed on the outer circumferential surface of the lens 2, and the protrusion 21 is engaged with the limiting groove 13 in the radial direction of the lens 2. When lens 2 was packed into frame 1, protruding 21 supported the lateral wall that presses spout 14, side frame 12 elastic deformation, the interval increase between two side frames 12, and protruding 21 joint is when spacing recess 13, and two side frames 12 reconversion are pressed from both sides tightly lens 2, and protruding 21 is injectd in spacing recess 13, and lens 2 can't become flexible easily.

As shown in fig. 1 and 2, in the present embodiment, two protrusions 21 are provided, two side frames 12 are each provided with a limiting groove 13, and the two protrusions 21 correspond to the two limiting grooves 13 one to one. Two protruding 21 and lens 2 integrated into one piece reduce manufacturing cost, and two protruding 21 are injectd respectively in two spacing recess 13, guarantee that the mounted position of lens 2 is accurate.

As shown in fig. 4 and 5, in the present embodiment, the sliding groove 14 on the inner wall of the main frame 11 is configured in an arc shape, and one end of the lens 2 near the main frame 11 is configured in an arc shape. When one end of the lens 2 close to the main frame 11 abuts against the side wall of the chute 14 of the main frame 11, the lens 2 is stably installed in the frame 1. When turning over lens 2 180 degrees, the position of the relative glasses person of wearing of surface and internal surface of lens 2 exchanges, and the unable adaptation of one end on the main frame 11 inside spout 14 of lens 2 near main frame 11, the unable frame 1 of packing into of lens 2 guarantee the accuracy of lens 2 installation direction.
