A part of the connecting wire A500 is arranged inside the ear hook block 300. By pulling the connecting wire A500, it can be pulled out from the inside of the ear hook block 300 to adjust the distance between the earphone 100 and the ear hook block 300, so as to adapt to the use of different users and improve the comfort of use. 00, the connecting wire A500 and the ear hook block 300 constitute the main body of the ear hook foldable hearing aid, which is the prior art. The connecting wire A500 can be folded to save space when not in use. The ear hook block 300 can be hung behind the ear to make it more stable when worn. It will not be repeated here; the inclined groove 208 and the guide groove 212 are each provided with three groups, and the clamping block 202 is also provided with three groups. The sliding rods 211 at the rear ends of the three groups of clamping blocks 202 are respectively in contact with the corresponding inner walls of the inclined groove 208 and the guide groove 212; Figure 4 As shown, when the dial block 209 is turned counterclockwise, the turntable 207 is driven to rotate counterclockwise synchronously, squeezing the sliding rod 211 at the rear end of the clamp block 202, which can drive the three groups of clamp blocks 202 to move toward the middle or outside at the same time; when not affected by external forces, the three groups of clamp blocks 202 remain in contact with the outer wall of the connecting line A500, and the clamp block 202 is made of rubber material, which can increase the friction between the connecting line A500 and the connecting line A500, thereby fixing the position of the connecting line A500; when the clamp block 202 moves toward the outside, it breaks away from the connecting line A500, and the fixing of the connecting line A500 can be released, and the connecting line A500 can be pulled out or moved into the inner wall of the ear hook block 300 to adjust its length on the outside, and then the distance between the ear hook block 300 and the earphone 100 is adjusted to adapt to different users.

[0034] The connecting wire A500 is fixedly connected to the outer wall of the earphone 100, and the connecting wire A500 is arranged in the inner wall of the ear hook block 300. The turntable 207 is rotatably connected to the inner wall of the connecting block 201; the connecting block 201 is fixedly connected to the outer wall of the ear hook block 300, the fixing block 203 is fixedly connected to the top outer wall of the connecting block 201, and the pull rod 205 passes through the front outer wall of the fixing block 203; one end of the spring A204 is fixedly connected to the outer wall of the wedge block 206, and the other end of the spring A204 is fixedly connected to the outer wall of the wedge block 206. It is fixedly connected to the inner wall of the fixed block 203; the shift block 209 passes through the outer wall of one side of the connecting block 201, and the shift block 209 is fixedly connected to the top outer wall of the turntable 207; the sliding rod 211 passes through the inner walls of the inclined groove 208 and the guide groove 212, the sliding rod 211 is fixedly connected to the rear end outer wall of the clamping block 202, and the clamping block 202 is slidably connected to the inner wall of the connecting block 201; the outer wall of the wedge block 206 is slidably connected to the inner wall of the fixed block 203, and the wedge block 206 is clamped in the groove 210.

[0035] When not affected by external forces, the wedge block 206 is kept popping outward and engaging with the groove 210 due to the elastic force of the spring A204 itself, and the straight surface of the wedge block 206 contacts the right inner wall of the groove 210, so that the shift block 209 cannot rotate counterclockwise. At this time, the shift block 209 contacts the top inner wall of the connecting block 201 and cannot rotate clockwise. When the pull rod 205 is pulled, the wedge block 206 moves toward the inner wall of the fixed block 203, and the spring A204 is forced to contract. When the wedge block 206 is When the slider 206 moves to the inner wall of the groove 210 and loses contact with it, the limit of the shifting block 209 is released, and the shifting block 209 can be rotated counterclockwise. At this time, the turntable 207 rotates counterclockwise synchronously, and the inclined groove 208 squeezes the outer wall of the sliding rod 211. The sliding rod 211 is guided by the guide groove 212 and moves along the inner wall of the guide groove 212. The three groups of sliding rods 211 drive the corresponding clamping blocks 202 to move outward at the same time, and lose contact with the connecting line A500, so that the connecting line A500 can be released. 00, pull the connecting wire A500 out of or insert it into the ear hook block 300, and adjust the length according to the needs of the user; after the adjustment is completed, the dial block 209 can be toggled clockwise to drive the turntable 207 to rotate clockwise, and when the inclined groove 208 squeezes the outer wall of the sliding rod 211, the three groups of clamping blocks 202 move toward the middle at the same time and contact with the outer wall of the connecting wire A500, so that the connecting wire A500 can be clamped and fixed, and the length between the ear hook block 300 and the earphone 100 is fixed; when the dial block is toggled, the length between the ear hook block 300 and the earphone 100 is fixed. During the process of adjusting the shift block 209, the outer wall of the shift block 209 generates a squeezing force on the arc surface of the wedge block 206, so that the wedge block 206 moves inward along the inner wall of the fixed block 203, and the spring A204 contracts under the force. When the shift block 209 is shifted to the position where the groove 210 corresponds to the position of the wedge block 206, the wedge block 206 is ejected due to the elastic force of the spring A204 and is engaged with the groove 210, so that the shift block 209 can be limited and the position of the three groups of clamping blocks 202 can be fixed at the same time, thereby completing the adjustment of the length of the connecting line A500.

[0039] Both ends of the connecting wire B403 are made of hard plastic material, so that they can be inserted into the mounting block 401 for connection; since the earphones 100 and the ear hook blocks 300 are worn on the user's ears on both sides respectively, the two sets of ear hook blocks 300 can be connected through the connecting wire B403, so that they can be hung on the user's neck when not in use temporarily, and can be directly picked up and worn when needed. There is no need to put the earphones 100 and the ear hook blocks 300 into the hearing aid box, and there is no need to take them out and wear them when in use, which is more convenient; when the user only needs to wear one set of earphones 100 and ear hook blocks 300, the connecting wire B403 can be removed from the ear hook blocks 300, so that only one set of earphones 100 can be worn, which is more flexible.

[0040] When the connecting wire B403 is installed on the ear hook block 300, the two ends of the connecting wire B403 can be inserted into the mounting block 401 at the rear end of the two sets of ear hook blocks 300. At this time, the arc surface of the clamping block 405 is squeezed by the outer wall of the mounting block 401 and moves inward along the inner wall of the front end of the connecting wire B403. The spring B404 is forced to shrink. When the two ends of the connecting wire B403 are inserted to the position corresponding to the clamping block 405 and the clamping slot 402, the clamping block 405 pops out to both sides under the elastic force of the spring B404 itself and is clamped with the clamping slot 402. The connecting wire B403 is fixed so that the two ends of the connecting wire B403 are connected and fixed to the mounting blocks 401 on the two groups of ear hook blocks 300; when the connecting wire B403 needs to be removed, the two groups of card blocks 405 can be pressed at the same time to make the card blocks 405 disengage from the inner wall of the card slot 402, so as to release the limit of the connecting wire B403, and take the connecting wire B403 out of the mounting block 401, so that the two groups of ear hook blocks 300 are detached from the connecting wire B403, so that it can be used separately, which is more flexible and convenient to use.
