[0090] Working principle:

[0091] First, the dual-axis motor 420 is started, and the output shaft of the dual-axis motor 420 drives the screw 430 to rotate. Under the action of the thread, the screw 430 drives the screw sleeve B440 to move along the axial direction of the screw 430, and the screw sleeve B440 drives the corresponding temple 120 to slide in the through groove, and the folding curtain 450 is deformed by the force, and the temple 120 drives the corresponding distance adjustment mechanism A300 and the earphone 200 to move synchronously, so that the position of the two temples 120 can be adjusted according to the distance between the two ears of the student;

[0092] Secondly, the student wears the VR all-in-one head display 100 on the head. At this time, the earphone 200 is squeezed by the head, so that the earphone 200 drives the clamping piece 340 and the inner tube 322 to slide toward the inner cavity of the outer tube 321, and the inner tube 322 drives the slider B3221 to slide in the inner cavity of the slide groove B3212, and the spring A323 is forced to shrink. The elastic force of the spring A323 is used to make the earphone 200 fit tightly to the student's ear to avoid sound leakage, which helps to improve the sound quality of the earphone 200; if the earphone 200 is not aligned with the ear, the earphone 200 is moved, so that the earphone 200 drives the distance adjustment mechanism A300 to rotate with the damping shaft on the temple 120 as the center until the earphone 200 rotates to the ear; if the earphone 200 is not aligned with the ear yet, the pressing block 331 can be pressed downward with force, and the pressing block 331 drives the tooth block 332 to The tooth block 332 drives the protrusion 337 to slide on the inner wall of the support shell 313. The tooth block 332 also drives the gear 334 and the rotating rod 333 to rotate. The gear 334 drives the tooth plate 335 to move, so that two of the tooth plates 335 drive the remaining tooth plate 335 to move synchronously in the direction of the pressing block 331. The spring B336 is forced to shrink until the tooth plate 335 is separated from the rack 312, and the rack 312 can be unlocked. At this time, the support shell 313 can be pushed, so that the support shell 313 drives the sleeve shell 311 to slide on the surface of the rack 312. The sleeve shell 311 drives the slide groove A3111, the support shell 313, the positioning member 330, the telescopic member B320, the clamping member 340 and the earphone 200 to move synchronously along the length direction of the rack 312, and the slider A3121 slides in the inner cavity of the slide groove A3111 until the earphone 200 is aligned with the ear (such as Figure 8 As shown), the pressing block 331 can be released, and the tooth plate 335 is reset and meshed with the corresponding position of the rack 312 by the elastic restoring force of the spring B336, so that the position of the earphone 200 can be adjusted according to the distance between the student's own ear and glasses;

[0093] Finally, an auxiliary tool matched with the screw head 344 is inserted into the inner cavity of the outer tube 321 through the through hole 3211 and aligned with the screw head 344, and the auxiliary tool is rotated. The auxiliary tool drives the screw head 344 and the stud 343 to rotate synchronously. Under the action of the thread, the stud 343 drives the screw sleeve A345 to move along the axial direction of the stud 343, and the screw sleeve A345 gradually approaches the screw head 344. The screw sleeve A345 drives one end of the connecting rod 346 to move, and the other end of the connecting rod 346 drives the block 347 to move on the support The surface of the frame 348 slides, causing the block 347 to gradually move toward the center of the slot 342, and then causing the multiple blocks 347 to gradually move closer together until they reach the maximum limit, thereby unlocking the pin 341. At this time, the earphone 200 can be taken out, causing the earphone 200 to drive the pin 341 and the slot 342 to gradually move away from the inner tube 322, until the pin 341 is separated from the inner cavity of the inner tube 322, thereby completing the disassembly operation of the earphone 200 to achieve the inspection or replacement of the earphone 200.
