The clamping blocks are matched with the through holes, so that the left lens and the right lens are firmly clamped and equally fixed at the nose bridge. The front part of the upper end of the accessory 20 is provided with a roller groove 23, a butterfly clamp 30 is rotatably arranged on the roller groove 23 through a roller 31, the butterfly clamp can be clamped on optical glasses worn daily, and the 3D lens clamping component disclosed by the utility model can be turned over at different angles through the matching of the roller and the roller groove.

As a further improvement, the fitting 20 is in an inverted trapezoid shape, the bottom of the inverted trapezoid shape of the fitting 20 is recessed upwards to form an arc shape, and the bottom of the recessed arc-shaped fitting is similar to the bridge of the nose and presents an arc shape, so that the whole mirror clamping assembly is more attractive in appearance and stronger in stereoscopic impression.

As a further improvement, a protrusion 111 protruding to the right is provided at the upper end of the right side of the left lens 11, and a protrusion 121 protruding to the left is provided at the upper end of the left side of the right lens 12 to form a middle beam 13 of the lens 10. The bottom of the bottom 211 of the T-shaped groove is in a crescent arc shape and is matched with the radian of the lower end of the middle beam 13, so that the lens is clamped better, and the lens 10 is prevented from shaking or falling off. Through cutting out the lens about having "nearly" font special shape, the amalgamation back, from taking the centre sill, simple structure compares traditional addding the centre sill and connects the lens or erects the attached mirror of lens through the picture frame, the cost is reduced.

In combination with the 3D imaging technology principle, the 3D lens needs to be a two-piece lens with different left and right polarized lights, so as to further improve, the left lens 11 is set as a horizontal polarized light lens, and the right lens 12 is set as a vertical polarized light lens.

The whole lens that presents shallow curved surface shape, as further improvement, T type tank bottom 211 is shallow curved surface spill, with well roof beam 13 cooperation is more firm, thereby prevents that lens 10 from rocking or causing to have the space between lens and the accessory and influence the normal use of pressing from both sides the mirror.

As a further improvement, the butterfly clip 30 includes a front clip portion 32 and a rear clip portion 33, the front clip portion 32 includes a left front leg and a right front leg and a front cross bar 322 connecting the two front legs 321, the front clip portion 32 and the rear clip portion 33 have the same structure, the front clip portion 32 and the rear clip portion 33 are pivoted together, a return spring 34 is disposed at the pivot, and a roller 31 is disposed on the front cross bar 322 of the front clip portion 32.

As a further improvement, the cross section of the roller 31 is in a rhombus shape, and a plurality of convex strips 311 are arranged on the surface of the rhombus-shaped roller 31 in an annular array. Correspondingly, the cross section of the roller groove 23 is in a rhombus shape, and a strip-shaped clamping pit 231 matched with the convex strip 311 is arranged inside the rhombus-shaped roller groove 23. When using this 3D clip mirror subassembly, when seeing the shadow clearance or other needs lift 3D clip mirror subassemblies temporarily, can adjust the height that the lens was lifted as required to through the cooperation of the sand grip that is provided with and the draw-in pit, with the better fixed height of keeping in adjusting of lens.

Example II,

On the basis of the first embodiment, the pivot structure is further improved as follows: the middle part of a front cross bar 322 of the front clamping part 32 extends backwards to form two parallel pivot seats 323, a rhombic roller 31 is arranged above the two parallel pivot seats 323, a connecting rod 324 is arranged below the two parallel pivot seats 323, and triangular clamping grooves 325 are arranged on the two parallel pivot seats 323. The rear bar 332 of the rear clip portion 33 snaps into the triangular snap slot 325. Thus, compared with a common circular slot, the triangular slot 325 can clamp the rear clamping portion 33 more tightly and firmly, and is not easy to fall out. In addition, the two ends of the front bar 322 of the front clip part 32 are protruded backwards to form reinforcing blocks 326, which can reinforce the clip legs and prevent the clip legs from being broken easily.

In a further improvement, the front clamping leg 321 of the front clamping part 32 of the butterfly clamp 30 is in a flat column shape, and a rubber sleeve is sleeved on the front clamping leg. The rear clamping legs 331 of the rear clamping part 33 of the butterfly clamp 30 are provided with flat rear rubber foot sleeves 333, and the flat clamping legs can increase the stress area, so that the butterfly clamp 30 is more tightly clamped on the optical glasses and is not easy to shake.
