The card cover 22 is in a four-leaf clover shape like the main frame 21 and includes frames corresponding to the four lens frames 211. A flat rotating shaft 42 penetrating the card cover 22 is provided at a side away from the rotating shaft sleeve 214 of the rotating gear 41. The card cover 22 is provided with an avoidance hole 227 for avoiding the rotating shaft 42. A rotating cap 43 is detachably provided on the rotating shaft 42. Thus, the rotating gear 41 can be driven to rotate by rotating the rotating cap 43.

[0027] It should be noted that, in this embodiment, Fig.15As shown, a clamping strip 421 is respectively provided on the side walls of the rotating shaft 42, and a fixing sleeve 431 adapted to the rotating shaft 42 is provided on the side of the rotating cap 43 opposite to the rotating shaft 42, and two clamping grooves 432 are correspondingly provided on the inner wall of the fixing sleeve 431 for clamping the clamping strip 421 respectively.

In this way, when the rotating cap 43 is rotated, the rotating shaft 42 can be driven to rotate, and then the rotating gear 41 can be driven to rotate. Here, the rotating cap 43 can be rotated clockwise or counterclockwise, and correspondingly, the rotating gear 41 can be rotated clockwise or counterclockwise.

[0028] In this embodiment, Figure 6 and Fig.14 As shown, the first fixed collar 212 located on one side is provided with a first connecting rod 215 extending to the bottom of the rotating gear 41 and meshingly connected with the rotating gear 41 at the bottom of the side close to the rotating gear 41, and the first fixed collar 212 located on the other side is provided with a second connecting rod 216 extending to the top of the rotating gear 41 and meshingly connected with the rotating gear 41 at the top of the side close to the rotating gear 41.

[0029] In this embodiment, when the rotating cap 43 is rotated clockwise, the rotating shaft 42 can be driven to rotate clockwise, thereby driving the rotating gear 41 to rotate clockwise. When the rotating gear 41 rotates clockwise, on the one hand, the first connecting rod 215 and the second connecting rod 216 are respectively and simultaneously moved outwardly in the horizontal direction. At this time, the first connecting rod 215 and the second connecting rod 216 are respectively and simultaneously moved in the horizontal direction away from the rotating gear 41, thereby driving the two first fixing rings 212 to respectively and simultaneously move outwardly in the two lens frames 211 in the horizontal direction, thereby expanding the two The distance between the first fixed ring 212 is increased, thereby increasing the distance between the two positive lenses 30. On the other hand, the third connecting rod 217 and the fourth connecting rod 218 are respectively moved outwardly in the vertical direction at the same time.

At this time, the first connecting rod 215 and the second connecting rod 216 are respectively moved inwardly in the horizontal direction toward the rotating gear 41 at the same time, thereby driving the two first fixed rings 212 to move inwardly in the horizontal direction in the two lens frames 211, thereby reducing the distance between the two first fixed rings 212, thereby reducing the pupil distance between the two positive lenses 30. On the other hand, the third connecting rod 217 and the fourth connecting rod 218 are respectively moved inwardly in the vertical direction at the same time. At this time, the third connecting rod 217 and the fourth connecting rod 218 are respectively moved inwardly in the vertical direction at the same time. 3 are respectively moved inwards along the vertical direction in the two lens frames 211, so as to reduce the distance between the two second fixing rings 213, and then reduce the distance between the two negative lenses 31. By setting the adjusting button 40, the effect of simultaneously adjusting the distance between the two positive lenses 30 and the distance between the two negative lenses 31 is achieved. In this way, the adjustment can be made according to the different pupil distances of users of different age groups. Although the pupil distances of users of different age groups are different, by setting the adjusting button 40, the distance between the two first fixing rings 212 and the distance between the two second fixing rings 213 can be adjusted at the same time, and then the distance between the two positive lenses 30 and the distance between the two negative lenses 31 can be adjusted at the same time. Then, corresponding adjustments can be made according to the different pupil distances of users of different age groups to meet the needs of users of different age groups, and effectively solve the problem that the existing flip mirror cannot be adjusted according to the different pupil distances of users of different age groups. ;
