Obviously, the embodiments described are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0048] It should be understood that all directional indications in the embodiments of the present application (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture.

For example, the terms "first," "second," and so on are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, the term "first" or "second" may explicitly or implicitly include at least one of the features.

[0051] It should be further understood that the term "and / or" used in this specification and the appended claims refers to and includes any and all possible combinations of one or more of the associated listed items.

[0052] Smart wearable products are finding increasingly widespread application, such as AR glasses. As wearable devices integrating high-tech optical and electronic components, ensuring the proper fit of the temples against the user's face during production and quality testing is crucial for both visual experience and device sealing. Consequently, the temples of AR glasses are designed to be flexible. During testing, these temples must be manually stretched to prevent interference with the testing system. This is not only inefficient but also makes it difficult to ensure consistent and accurate testing.

[0053] Therefore, an embodiment of the present application proposes an auxiliary opening device that can automatically open the temples of the AR glasses to ensure the stability and repeatability of the test, and ensure that during the test, the temples of the AR glasses will not interfere with the test system.

[0054] See also Figures 1 to 3 The embodiment of the present application proposes an auxiliary opening device 100, which includes a fixing mechanism 10, a supporting mechanism 20 and a first adjusting mechanism 30. The fixing mechanism 10 is used to place the AR glasses 200 to be tested. The AR glasses 200 include a frame and two temples 210 arranged opposite to each other. The supporting mechanism 20 includes a first supporting arm 21 and a second supporting arm 22; the first adjusting mechanism 30 is connected to the supporting mechanism 20, and the first adjusting mechanism 30 is used to drive the first supporting arm 21 and the second supporting arm 22 to move between an initial position and a preset end position; the first supporting arm 21 and the second supporting arm 22 respectively abut against the two temples 210 of the AR glasses 200 to change the position of the two temples 210 relative to the frame. Specifically, when the first supporting arm 21 and the second supporting arm 22 move to the preset end position, they respectively abut against the opposite sides of the two temples 210 of the AR glasses 200 to open the two temples 210.

[0055] The auxiliary expansion device 100 proposed in the embodiment of the present application can be used to firmly place the AR glasses 200 to be tested through the setting of the fixing mechanism 10 to avoid the position deviation of the AR glasses 200. The setting of the first adjustment mechanism 30 can drive the support mechanism 20 to automatically expand the temples 210 of the AR glasses 200 or automatically reset them to the initial position, ensuring that during the test, the temples 210 of the AR glasses 200 will not interfere with the test system, while reducing manual operation and improving test efficiency. The movement position and movement distance of the first support arm 21 and the second support arm 22 can be adjusted to a fixed position by the first adjustment mechanism 30, ensuring that the expanded position of the temples 210 is the same during each test, thereby ensuring the stability, repeatability and flexibility of the test, and ensuring the consistency and accuracy of the test.

[0056] For example, when the AR glasses 200 are placed on the fixing mechanism 10, the initial positions of the first support arm 21 and the second support arm 22 can be between the two temples 210 of the AR glasses 200 but not in contact with the two temples 210, or can be in a position where they just contact the two temples 210 but do not apply any force to the two temples 210. At this time, the temples 210 are in a naturally open state and are not stretched. The preset end positions of the first support arm 21 and the second support arm 22 can be adjusted accordingly according to AR glasses 200 of different sizes or shapes. When the first support arm 21 and the second support arm 22 are at the preset end positions, forces are applied to the two temples 210 in opposite directions, so that the two temples 210 can be stretched due to their certain elasticity to avoid interference with the test system.

[0057] In some usage scenarios, the auxiliary expansion device 100 can be placed under the test system to fix the AR glasses 200 and automatically expand the temples 210 of the AR glasses 200 during testing. When the test is completed, the support mechanism 20 can be driven to return to the initial position, so that the temples 210 are restored to their original state.

[0058] See also Figures 1 to 6 In some embodiments, the first adjustment mechanism 30 includes a first adjustment member 31, a second adjustment member 32, a guide member 33 and a drive assembly 34, the first adjustment member 31 is connected to the first support arm 21; the second adjustment member 32 is connected to the second support arm 22; the guide member 33 extends along a first direction, and the first adjustment member 31 and the second adjustment member 32 are movably connected to the guide member 33, and the first direction is the relative movement direction of the first support arm 21 and the second support arm 22; the drive assembly 34 is connected to the first adjustment member 31 and the second adjustment member 32, and an initial position and a preset end position are provided along the guide member 33. There can be multiple preset end positions, which can be adjusted accordingly according to the model and size of the AR glasses; the drive assembly 34 is used to drive the first adjustment member 31 and the second adjustment member 32 to move relative to each other along the guide member 33, so as to drive the first support arm 21 and the second support arm 22 to move between the initial position and the preset end position. Therefore, the setting of the guide member 33 can guide the movement of the first adjusting member 31 and the second adjusting member 32 to avoid deviation of the movement trajectory. The setting of the driving component 34 can automatically drive the first adjusting member 31 and the second adjusting member 32 to move relative to each other, thereby driving the first support arm 21 and the second support arm 22 to automatically open the temples 210 of the AR glasses 200 to ensure the stability and repeatability of the test.

[0059] Exemplarily, the guide member 33 can be a slide rail, and the first adjustment member 31 and the second adjustment member 32 can be sliders slidably connected to the slide rail, thereby guiding the movement trajectory of the first support arm 21 and the second support arm 22, thereby improving the accuracy and stability of the relative movement of the first support arm 21 and the second support arm 22.

[0060] like Figure 3As shown, in some embodiments, the drive assembly 34 includes a screw rod 341, a first nut seat 342, a second nut seat 343 and a driving member 344, the screw rod 341 includes a forward thread segment 3411 and a reverse thread segment 3412 connected to each other, specifically, the forward thread segment 3411 and the reverse thread segment 3412 are both provided with external threads, and the spiral direction of the external thread of the forward thread segment 3411 is opposite to that of the external thread of the reverse thread segment 3412; the first nut seat 342 is connected to the forward thread segment 3411 and the first adjusting member 344. The screw rod 341 is connected to the second nut seat 343 and the second adjusting member 32. The driving member 344 is connected to the screw rod 341, and the driving member 344 is used to drive the screw rod 341 to rotate, so as to drive the first nut seat 342 and the second nut seat 343 to move in opposite directions on the screw rod 341, so as to drive the first adjusting member 31 and the second adjusting member 32 to move toward or away from each other along the guide member 33, thereby driving the first support arm 21 and the second support arm 22 to move between the initial position and the preset end position. Therefore, by providing external threads with opposite spiral directions on the two parts of the screw rod 341, the screw rod 341 can produce opposite movement effects when rotating, thereby driving the first adjusting member 31 and the second adjusting member 32 to move toward or away from each other along the guide member 33, thereby driving the first support arm 21 and the second support arm 22 to move relatively away from or relatively close to each other, so as to achieve movement between the initial position and the preset end position.

[0061] For example, the driving member 344 may be a motor or other power source capable of driving the screw rod 341 to rotate.

[0062] like Figure 2 As shown, in some embodiments, the first adjustment mechanism 30 further includes a first limit member 35, which is provided in the direction of the motion trajectory of the first adjustment member 31. The first limit member 35 is used to abut the first adjustment member 31 when the first adjustment member 31 moves in a direction away from the second adjustment member 32 to a first limit position. Specifically, when the first adjustment member 31 moves in a direction away from the second adjustment member 32, that is, moves in a direction of spreading the temple 210, the provision of the first limit member 35 can limit the limit position of the first adjustment member 31, so that the first adjustment member 31 can properly spread the temple 210 to avoid interference between the temple 210 and the test system while not over-spreading the temple 210, thereby avoiding damage to the temple 210. The first limit position can be adjusted according to different models or sizes of AR glasses.

[0063] Furthermore, in some embodiments, the first adjustment mechanism 30 further includes a second limit member 36, which is provided in the direction of the movement trajectory of the second adjustment member 32. The second limit member 36 is used to abut the second adjustment member 32 when the second adjustment member 32 moves in a direction away from the first adjustment member 31 to a second extreme position. Specifically, when the second adjustment member 32 moves in a direction away from the first adjustment member 31, that is, moves in a direction of spreading the temples 210, the provision of the second limit member 36 can limit the extreme position of the second adjustment member 32, so that the second adjustment member 32 can properly spread the temples 210 to avoid interference between the temples 210 and the test system while not over-spreading the temples 210, thereby avoiding damage to the temples 210. The second extreme position can be adjusted according to different models or sizes of AR glasses.

[0064] See also Figure 5 In some embodiments, the first limiting member 35 may include a first fixing seat 351, a first fixing portion 352 and a first blocking portion 353, and the second limiting member 36 may include a second fixing seat 361, a second fixing portion 362 and a second blocking portion 363. The first fixing seat 351 and the second fixing seat 361 may be respectively arranged on both sides of the guide member 33 along the first direction. The first adjusting member 31 is arranged on a side of the guide member 33 close to the first fixing seat 351, and the second adjusting member 32 is arranged on a side of the guide member 33 close to the second fixing seat 361. The first fixing portion 352 is installed on the first fixed seat 351, and the first blocking portion 353 is connected to one end of the first fixed portion 352 toward the first adjusting member 31, and is used to abut the first adjusting member 31 when the first adjusting member 31 moves in the direction away from the second adjusting member 32 to the first extreme position. The second fixed portion 362 is installed on the second fixed seat 361, and the second blocking portion 363 is connected to one end of the second fixed portion 362 toward the second adjusting member 32, and is used to abut the second adjusting member 32 when the second adjusting member 32 moves in the direction away from the first adjusting member 31 to the second extreme position.

[0065] In some embodiments, the first blocking portion 353 can be made entirely of elastic material, or the portion in contact with the first adjusting member 31 can be made of elastic material, so that it can elastically abut the first adjusting member 31, limiting the extreme position of the first adjusting member 31 while avoiding rigid collision with the first adjusting member 31.

[0066] In some embodiments, the second blocking portion 363 can be made entirely of elastic material, or the portion in contact with the second adjusting member 32 can be made of elastic material, so that it can elastically abut the second adjusting member 32, limiting the extreme position of the second adjusting member 32 while avoiding rigid collision with the second adjusting member 32.

[0067] See also Figure 3In some embodiments, the auxiliary expansion device 100 further includes a second adjustment mechanism 40, and the second adjustment mechanism 40 includes a third adjustment member 41 and a fourth adjustment member 42. The third adjustment member 41 is provided at the connection between the first adjustment member 31 and the first support arm 21, and the fourth adjustment member 42 is provided at the connection between the second adjustment member 32 and the second support arm 22; the third adjustment member 41 has a first locking state and a first unlocking state. In the first locking state, the third adjustment member 41 is used to lock the first support arm 21 to the first adjustment member 31, so that the posture of the first support arm 21 is fixed. In the first unlocking state, the third adjustment member 41 is used to lock the first support arm 21 to the first adjustment member 31, so that the posture of the first support arm 21 is fixed. The joint 41 is used to release the lock of the first support arm 21 so that the user can adjust the posture of the first support arm 21 so that the first support arm 21 is adapted to the AR glasses 200; the fourth adjustment member 42 has a second locking state and a second unlocking state. In the second locking state, the fourth adjustment member 42 is used to lock the second support arm 22 to the second adjustment member 32 so that the posture of the second support arm 22 is fixed. In the second unlocking state, the fourth adjustment member 42 is used to release the lock of the second support arm 22 so that the user can adjust the posture of the second support arm 22 so that the second support arm 22 is adapted to the AR glasses 200. Among them, the fixed posture of the first support arm 21 and the second support arm 22 refers to the fixed position and angle of the first support arm 21 and the second support arm 22, so that the temples 210 can be stably spread open to ensure the consistency and accuracy of the test.

[0068] Therefore, through the setting of the third adjustment member 41 and the fourth adjustment member 42, the first support arm 21 and the second support arm 22 can be conveniently locked or unlocked. When the AR glasses 200 of different sizes or shapes are replaced for testing, the first support arm 21 and the second support arm 22 can be unlocked and adjusted according to the corresponding AR glasses 200. When the first support arm 21 and the second support arm 22 are adjusted to a suitable posture, so that the initial angle of the first support arm 21 and the second support arm 22 adapts to the corresponding AR glasses 200, ensuring that the temple 210 does not interfere with the test system during optical testing, and then the first support arm 21 and the second support arm 22 are locked, so that when the first support arm 21 and the second support arm 22 reach the preset end position, they can fit the position of the temple 210 of the corresponding AR glasses 200, thereby facilitating the expansion of the temple 210. It is flexible in operation and has a wide range of applications.

[0069] Further, such as Figure 3As shown, in some embodiments, the first support arm 21 includes a first movable portion 211, a first connecting portion 212 and a first abutting portion 213, the first abutting portion 213 is used to abut one of the temples 210 of the AR glasses 200 at a preset end position, the first connecting portion 212 is connected to the first movable portion 211 and the first abutting portion 213, the first movable portion 211 is connected to the first adjusting member 31, in the first locking state, the third adjusting member 41 is used to enable the first movable portion 211 to lock the first adjusting member 31, and in the first unlocking state, the third adjusting member 41 is used to release the lock of the first movable portion 211, so that the first movable portion 211 can translate and / or rotate relative to the first adjusting member 31, so that the user can adjust the posture of the first support arm 21, so that the first support arm 21 is adapted to the AR glasses 200; the second support arm 22 includes a second movable part 221, a second connecting part 222 and a second abutting part 223, the second abutting part 223 is used to abut the other temple 210 of the AR glasses 200 at the preset end position, the second connecting part 222 is connected to the second movable part 221 and the second abutting part 223, the second movable part 221 is connected to the second adjusting member 32, in the second locking state, the fourth adjusting member 42 is used to make the second movable part 221 lock the second adjusting member 32, in the second unlocking state, the fourth adjusting member 42 is used to release the lock of the second movable part 221, so that the second movable part 221 can be translated and / or rotated relative to the second adjusting member 32, so that the user can adjust the posture of the second support arm 22 according to different models of AR glasses 200, so that the second support arm 22 can adapt to the AR glasses 200 and achieve precise adjustment.

[0070] Thus, the translation of the first movable portion 211 drives the overall translation of the first connecting portion 212 and the first abutting portion 213, thereby adjusting the position of the first support arm 21 in the first direction, that is, the left-right direction. The rotation of the first movable portion 211 drives the first abutting portion 213 to swing up and down, thereby adjusting the height of the first support arm 21. This allows the first expandable portion to adjust its posture to suit AR glasses 200 of different sizes or shapes, thereby fitting the corresponding temple 210 of the AR glasses 200. The translation of the second movable portion 221 drives the overall translation of the second connecting portion 222 and the second abutting portion 223, thereby adjusting the position of the second support arm 22 in the first direction, that is, the left-right direction. The rotation of the second movable portion 221 drives the second abutting portion 223 to swing up and down, thereby adjusting the height of the second support arm 22. This allows the second expandable portion to adjust its posture to suit AR glasses 200 of different sizes or shapes, thereby fitting the corresponding temple 210 of the AR glasses 200.

[0071] In some embodiments, the first movable portion 211 , the first connecting portion 212 and the first abutting portion 213 may be integrally formed or separately connected, and the second movable portion 221 , the second connecting portion 222 and the second abutting portion 223 may be integrally formed or separately connected.

[0072] In some embodiments, the ends of the first abutting portion 213 and the second abutting portion 223 that contact the temple 210 can be covered with flexible pads, so that they can elastically abut the temple 210, avoiding damage to the temple 210 while stretching the temple 210.

[0073] See also Figure 3 and Figure 6 When the cam 311 is in the unlocked position, the third adjusting member 41 is used to lock the first limiting portion 311 and the second limiting portion 312 so that the first movable portion 211 is firmly fixed in the first limiting groove 313, thereby locking the first movable portion 211 to the first adjusting member 31. When the cam 311 is in the unlocked position, the third adjusting member 41 is used to release the lock between the first limiting portion 311 and the second limiting portion 312, thereby releasing the lock of the first movable portion 211, so that the first movable portion 211 can move relative to the first limiting groove 313 and When the second locking state is reached, the fourth adjusting member 42 is used to lock the third limiting portion 321 and the fourth limiting portion 322 so that the second movable portion 221 is firmly set in the second limiting groove 323, thereby locking the second movable portion 221 to the second adjusting member 32. When the second unlocking state is reached, the fourth adjusting member 42 is used to release the lock between the third limiting portion 321 and the fourth limiting portion 322, thereby releasing the lock of the second movable portion 221, so that the second movable portion 221 can translate and / or rotate relative to the second limiting groove 323.

[0074] Therefore, by setting the first limiting portion 311 and the second limiting portion 312, a certain gap can be provided for the first movable portion 211 to move in the first limiting groove 313 when the third adjusting member 41 is in the unlocked state, so that the first movable portion 211 can be translated and rotated. When adjusted to a suitable posture, the first limiting portion 311 and the second limiting portion 312 are locked by the third adjusting member 41, thereby clamping the first movable portion 211 in the first limiting groove 313, so that the posture of the first support arm 21 is fixed. By setting the third limiting portion 321 and the fourth limiting portion 322, a certain gap can be provided for the second movable portion 221 to move in the second limiting groove 323 when the fourth adjusting member 42 is in the unlocked state, so that the second movable portion 221 can be translated and rotated. When adjusted to a suitable posture, the third limiting portion 321 and the fourth limiting portion 322 are locked by the fourth adjusting member 42, thereby clamping the second movable portion 221 in the second limiting groove 323, so that the posture of the second support arm 22 is fixed.

[0075] In some embodiments, the third adjusting member 41 and the fourth adjusting member 42 can use fixing screws, and one or more third adjusting members 41 and the fourth adjusting member 42 can be provided. Screw holes compatible with the fixing screws can be opened on the first adjusting member 31 and the second adjusting member 32. The screw hole of the first adjusting member 31 passes through the first limiting portion 311 and the second limiting portion 312, and the screw hole of the second adjusting member 32 passes through the third limiting portion 321 and the fourth limiting portion 322, so that the third adjusting member 41 can be switched between the first unlocked state and the first locked state by turning the knob of the third adjusting member 41. Similarly, the fourth adjusting member 42 can be switched between the second unlocked state and the second locked state by turning the knob of the fourth adjusting member 42.

[0076] See also Figure 3 In some embodiments, the first movable portion 211 and the second movable portion 221 extend along a first direction, the first connecting portion 212 and the second connecting portion 222 extend along a second direction, and the first abutting portion 213 and the second abutting portion 223 extend along a third direction. The second direction is the height direction of the auxiliary opening device 100, and the third direction is the arrangement direction of the fixing mechanism 10 and the first adjustment mechanism 30. The first, second, and third directions are arranged perpendicularly to each other. For example, the first direction can be left-right, the second direction can be up-down, and the third direction can be front-back. When the AR glasses 200 are placed on the fixing mechanism 10, the two temples 210 face upward. The first connecting portion 212 and the second connecting portion 222 can partially raise the height of the first support arm 21 and the second support arm 22 to match the height of the temples 210. The first abutting portion 213 and the second abutting portion 223 can be arranged to intersect or be perpendicular to the temples 210 to facilitate opening the temples 210.

[0077] In some embodiments, the first movable portion 211, the first connecting portion 212, the first abutting portion 213, the second movable portion 221, the second connecting portion 222 and the second abutting portion 223 can be constructed as a rod-shaped structure, so that it is convenient to spread the temple 210 while facilitating the adjustment of the posture to adapt to the temple 210 and reducing the volume.

[0078] See also Figure 1 、 Figure 2 and Figure 4 In some embodiments, the auxiliary expansion device 100 further includes a base 50, a first positioning assembly 60 and a second positioning assembly 70, and the fixing mechanism 10 and the first adjustment mechanism 30 are both installed on the base 50; the first positioning assembly 60 includes a first trigger member 61 and a first detection member 62, one of the first trigger member 61 and the first detection member 62 is provided on the first adjustment member 31, and the other of the first trigger member 61 and the first detection member 62 is provided on the base 50, and the first trigger member 61 is used to contact the first detection member 62 when the first support arm 21 moves to a preset end position or an initial position, so as to trigger the generation of a signal and emit it; the second positioning assembly 70 includes a second trigger member 71 and a second detection member 72, one of the second trigger member 71 and the second detection member 72 is provided on the second adjustment member 32, and the other of the second trigger member 71 and the second detection member 72 is provided on the base 50, and the second trigger member 71 is used to contact the second detection member 72 when the second support arm 22 moves to a preset end position or an initial position, so as to trigger the generation of a signal and emit it. Therefore, by disposing the first positioning assembly 60 and the second positioning assembly 70 , accurate feedback signals can be generated when the first support arm 21 and the second support arm 22 move to the preset end position or initial position, thereby improving control accuracy.

[0079] For example, it can be configured that when the first support arm 21 reaches a preset end position, the first trigger member 61 contacts the first detection member 62, and when the second support arm 22 reaches the initial position, the second trigger member 71 contacts the second detection member 72. Alternatively, it can be configured that when the second support arm 22 reaches a preset end position, the second trigger member 71 contacts the second detection member 72, and when the first support arm 21 reaches the initial position, the first trigger member 61 contacts the first detection member 62. This allows the support mechanism 20 to provide signal feedback when it reaches both the preset end position and the initial position.

[0080] Of course, in other examples, it is also possible to configure that when the first support arm 21 and the second support arm 22 reach the preset end position, the first trigger member 61 contacts the first detection member 62 simultaneously with the second trigger member 71 contacts the second detection member 72. Alternatively, it is also possible to configure that when the first support arm 21 and the second support arm 22 reach the initial position, the first trigger member 61 contacts the first detection member 62 simultaneously with the second trigger member 71 contacts the second detection member 72.

[0081] In some embodiments, the first positioning assembly 60 and the second positioning assembly 70 can use a photoelectric sensor or other position detection sensor, the first trigger 61 can be installed on the first adjustment member 31, and the first detection member 62 can be installed at a corresponding position on the base 50. When the first support arm 21 moves to a preset end position or an initial position, the first trigger 61 blocks the light to trigger the generation and issuance of a signal, the second trigger 71 can be installed on the second adjustment member 32, and the second detection member 72 can be installed at a corresponding position on the base 50. When the second support arm 22 moves to a preset end position or an initial position, the second trigger 71 blocks the light to trigger the generation and issuance of a signal. Of course, in other embodiments, the positions of the first trigger 61 and the second adjustment member 32 can also be interchanged, and the positions of the second trigger 71 and the second adjustment member 32 can also be interchanged.

[0082] In some embodiments, the first detection member 62 and the second detection member 72 are detachably connected to the base 50, such as being installed on the base 50 in a detachable manner using screws, snaps, etc. Multiple mounting positions can be set on the base 50, such as multiple screw holes, etc. The first detection member 62 and the second detection member 72 can be installed at any mounting position, so that the positions of the first detection member 62 and the second detection member 72 can be adjusted according to different preset end positions corresponding to AR glasses 200 of different models or sizes.

[0083] See also Figure 1 and Figure 2 In some embodiments, the fixing mechanism 10 includes a support base 11 and a fixing member 12. The support base 11 is used to support the AR glasses 200; the fixing member 12 is used to fix the AR glasses 200 to the support base 11. Thus, the fixing member 12 and the support base 11 can be arranged to stably place the AR glasses 200. The support base 11 is fixed to the base 50 and can be provided with a slot adapted to the AR glasses 200 to facilitate the stable placement of the AR glasses 200.

[0084] In some embodiments, the fixing member 12 can be a clamping plate, one end of which is rotated by a hinge, and the other end of the supporting plate can be detachably connected to the support seat 11 by means of a snap or magnet. The hinge setting facilitates the opening and clamping of the clamping plate, thereby facilitating the clamping and fixing of the AR glasses 200 on the support seat 11.

[0085] In some embodiments, the auxiliary opening device 100 further includes a control mechanism 80, which is electrically connected to the first adjustment mechanism 30. The control mechanism 80 is configured to control the driving of the first adjustment mechanism 30 to drive the first support arm 21 and the second support arm 22 to move between an initial position and a predetermined end position. Thus, the control mechanism 80 can control the first adjustment mechanism 30 to automatically adjust the movement positions of the first support arm 21 and the second support arm 22, thereby facilitating automatic opening and resetting of the temple 210, achieving precise control, preventing interference between the temple 210 and the testing system, and reducing manual operation, thereby improving testing efficiency.

[0086] Among them, the first detection member 62 and the second detection member 72 are communicatively connected to the control mechanism 80, so that the in-position signal can be fed back to the control mechanism 80, which helps the control mechanism 80 to control the driving member 344 to stop driving after the first support arm 21 and the second support arm 22 reach the preset end position, so that the first support arm 21 and the second support arm 22 can stably support the temple 210.

[0087] In actual application, the AR glasses 200 can be placed on the fixing mechanism 10 first, and the first support arm 21 and the second support arm 22 can be connected to the two temples 210 of the AR glasses 200 respectively. Then, the postures of the first support arm 21 and the second support arm 22 can be adjusted by the second adjustment mechanism 40 to adjust the initial angles of the first support arm 21 and the second support arm 22 to adapt to the size of the AR glasses 200 and ensure that the temples 210 do not interfere with the test system during the optical test. Then, the control mechanism 80 issues a command to control the first adjustment component to drive the first support arm 21 and the second support arm 22 to move to the preset end position to spread the two temples 210. After the optical test is completed, the control mechanism 80 issues a command again to control the first adjustment component to drive the first support arm 21 and the second support arm 22 to return to the initial position, so that the temples 210 are reset.
