In a preferred embodiment, the movable member 220 is provided with an opening, and the top of the gear 2210 protrudes through the opening.

In this embodiment, the gear 2210 protrudes from the movable member 220, so that a user can conveniently touch the edge of the gear 2210 and toggle the edge of the gear 2210 to change the length of the temple 20.

In a preferred embodiment, the fixing member 210 is provided with a limiting device 50, and the limiting device 50 is used for limiting the movement position of the gear 2210.

The limiting device 50 prevents the gear 2210 from sliding out of the rack 2110, thereby avoiding complete separation of the stationary member 210 and the movable member 220. In general, protrusions may be provided at both ends of the rack 2110 to restrict the rack 2110 from being always located in the rack 2110. Of course, the limiting device 50 may not be fixedly disposed on the rack 2110.

In a more preferred embodiment, referring to fig. 2, the limiting device 50 includes a limiting block 510 and a limiting groove 520, wherein the limiting block 510 and the limiting groove 520 are respectively disposed near two ends of the rack 2110, and the limiting block 510 and the limiting groove 520 are respectively disposed on front and rear sides of the gear 2210 and are respectively used for limiting the movement position of the gear 2210.

In general, the limiting block 510 or the limiting groove 520 may be disposed on both the front and rear sides of the gear 2210 to perform a limiting function.

In the embodiment of the present utility model, an interface (not shown) for connecting a power line is provided on the movable member 220.

The main purpose of the power cord 60 is to power the control chip of the AR glasses, however, the power cord 60 may also provide power to the audio module 40.

If the user wears the AR glasses of the above embodiment and perceives that the visual relief is not proper, the user can touch the gear 2210 with both left and right hands at the same time and then toggle the gear 2210 to move the movable member 220 and the fixed member 210 relatively. That is, the position where the temple 20 is hung at the ear is changed, and the user finally achieves the effect of adjusting the visual relief.

In this embodiment, the sliding gear 2210 and the rack 2110 are matched to adjust the length of the glasses leg 20, so that different visual reliefs can be adjusted, and the AR glasses can meet the wearing requirements of different types of people, and good images can be obtained.
