A first rotating shaft 1341 and a second rotating shaft 1342 mounted on the adjustment frame 1340 are disposed within the sliding hole 13111. The first rotating shaft 1341 slides within the sliding hole 13111 in response to the adjustment frame 1340 rotating about the rotation axis of the second rotating shaft 1342. The second rotating shaft 1342 slides within the sliding hole 13111 in response to the adjustment frame 1340 rotating about the rotation axis of the first rotating shaft 1341. In some embodiments, the outer diameter of the main body 1343 of the adjustment frame 1340 is smaller than the inner diameter of the support portion 1311 of the fixed frame 1310. The main body 1343 is disposed within the support portion 1311, and the first rotating shaft 1341 and the second rotating shaft 1342 are disposed within the sliding hole 13111, thereby achieving a sliding connection between the adjustment frame 1340 and the fixed frame 1310.

[0078] In some embodiments, when the first adjustment ring 1320 and the second adjustment ring 1330 rotate relative to the fixing frame 1310, the first adjustment ring 1320 and the second adjustment ring 1330 are rotated in the fifth direction (eg Figure 5 Y1 direction) or the sixth direction (such as Figure 5The first adjusting ring 1320 slides in the Y2 direction (in the middle Y2 direction), thereby driving the adjusting frame 1340 to slide in the fifth direction or the sixth direction, where the fifth direction is opposite to the sixth direction, thereby adjusting the position of the adjusting frame 1340. Specifically, the first adjusting ring 1320 rotates relative to the fixing frame 1310 within a range that does not abut the first boss 1321 and the second boss 1322, and the second adjusting ring 1330 rotates relative to the fixing frame 1310 in the same direction as the first adjusting ring 1320 within a range that does not abut the third boss 1331 and the fourth boss 1332.

Figure 5 When the first adjustment ring 1320 and the second adjustment ring 1330 rotate together relative to the fixing frame 1310 toward the fixing frame 1310, and the first adjustment ring 1320 does not abut the first boss 1321 and the second boss 1322 and the second adjustment ring 1330 does not abut the third boss 1331 and the fourth boss 1332, the first adjustment ring 1320 and the second adjustment ring 1330 drive the adjustment frame 1340 to slide relative to the fixing frame 1310 toward the fixing frame 1310, that is, toward Figure 5 The adjustment frame 1340 then drives the optical engine 131 to adjust the position in the fifth or sixth direction, which can be used to adjust the images viewed by the user's left and right eyes respectively, so that the binocular vision is integrated, and the product qualification rate is also improved.

[0080] The optical machine 131 can be driven by the adjustment frame 1340, and can adjust the angle in any of the first and second directions as needed, or the angle in any of the third and fourth directions as needed, or the position in any of the fifth and sixth directions as needed, thereby adjusting the angle and position. This can be used to adjust the images viewed by the user's left and right eyes respectively, so that the binocular vision is integrated, and at the same time, the product qualification rate will be improved.

[0081] The first boss 1321 and the second boss 1322 are symmetrically arranged about the first axis A1, so that the first adjustment ring 1320 can rotate in a larger range, thereby increasing the angle or position adjustment range of the adjustment frame 1340 and further increasing the angle or position adjustment range of the optical engine 131.

[0082] The third boss 1331 and the fourth boss 1332 are symmetrically arranged about the second axis A2, so that the second adjustment ring 1330 can rotate in a larger range, thereby increasing the angle or position adjustment range of the adjustment frame 1340 and further increasing the angle or position adjustment range of the optical engine 131.
