[0022] The present invention will now be further described in detail in conjunction with the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0023] Reference Figure 1 , Figure 2 and Figure 3 As shown, the utility model provides a technical solution: an anti-howling hearing aid, comprising a hearing aid body 1, a conductive wire 2 is installed on the left side of the hearing aid body 1, an earplug 3 is installed at the bottom of the conductive wire 2, a first U-shaped block 4 is fixedly connected to the bottom of the hearing aid body 1, a take-up roller 17 is rotatably connected to the internal rotating shaft of the first U-shaped block 4, a connecting wire 5 is installed on the surface of the take-up roller 17, a connecting block 6 is fixedly connected to the bottom of the connecting wire 5, a notch 7 is provided at the bottom of the connecting block 6, two moving blocks 8 are slidably connected inside the notch 7, a clamping plate 9 is fixedly connected to the bottom of the moving block 8, a thrust spring 10 is fixedly connected to one side of the clamping plate 9, and one side of the thrust spring 10 is fixedly connected to the inside of the notch 7. A staff member pushes the two moving blocks 8 to slide inside the notch 7, so that the moving blocks 8 drive the clamping plate 9 to move, and at the same time, the two clamping plates 9 are approached to each other by the force of the thrust spring 10, so that the clamping plate 9 can be clamped with clothing, thereby preventing the hearing aid body 1 from falling off during use.

[0024] Reference Figure 3 As shown, in the present embodiment: the front end and the rear end of the inner cavity of the slot 7 are provided with limiting slots 11, the front end and the rear end of the moving block 8 are fixedly connected to the limiting block 12, and the moving range of the moving block 8 is limited by the coordinated use of the limiting slots 11 and the limiting block 12, so as to prevent the moving block 8 from escaping from the inside of the slot 7, thereby improving the stability of the clamping plate 9 during use.

[0025] Reference Figure 2 As shown, in this embodiment: the inner wall of the clamping plate 9 is fixedly connected with a magnet 13. By arranging the magnet 13 on the inner wall of the clamping plate 9, the magnet 13 can make the clamping plate 9 tighter when clamping.

[0026] Reference Figure 1 and Figure 4 As shown, in this embodiment: the front end of the connecting block 6 is fixedly connected to the internal shaft of the second U-shaped block 14, which is rotatably connected to the clamping plate 15. When the staff has finished clamping, the clamping plate 15 is moved downward so that the bottom of the clamping plate 15 can limit the two clamping plates 9, making it more stable when the staff is in use.

[0027] Reference Figure 4As shown, in this embodiment: the bottom of the clamping plate 15 is fixedly connected with a return spring 16, and the bottom of the return spring 16 is fixedly connected to the inside of the second U-shaped block 14. By setting the return spring 16, the return spring 16 will drive the clamping plate 15 to move downward quickly through its own force, so that the staff can fix the clamping plate 9 more stably and quickly.

[0028] Reference Figure 5 and Figure 6 As shown, in the present embodiment: a rotating hole 18 is provided at the front end of the first U-shaped block 4, a round rod 19 is rotatably connected inside the rotating hole 18, a rear end of the round rod 19 is fixedly connected to one end of the take-up roller 17, a telescopic groove 21 is provided at the front end of the round rod 19, a telescopic rod 22 is fixedly connected to the rear end of the inner cavity of the telescopic groove 21, a turning handle 20 is installed at the front end of the telescopic rod 22, and the staff can drive the round rod 19 and the take-up roller 17 to rotate by turning the turning handle 20, so that the staff can store the connecting line 5 conveniently, thereby avoiding the situation where the connecting line 5 is too long and cluttered, and improving the convenience of using the connecting line 5.

[0029] Reference Figure 5 and Figure 6 As shown, in the present embodiment: the rear end of the turning handle 20 is fixedly connected with a connecting spring 23, the rear end of the connecting spring 23 is fixedly connected with the inside of the telescopic slot 21, the front end of the first U-shaped block 4 is provided with a slot 24, and the rear end of the turning handle 20 is fixedly connected with a clamping block 25. When the staff does not use the take-up roller 17, the position of the take-up roller 17 is limited by inserting the clamping block 25 into the slot 24 starting from the front end of the first U-shaped block 4. At the same time, the elastic force of the connecting spring 23 makes the clamping block 25 more stable when it is clamped into the slot 24.

[0030] The working principle of the utility model is as follows: the staff pushes the two moving blocks 8 to slide inside the slot 7, so that the moving blocks 8 will drive the clamping plates 9 to move, and at the same time, the two clamping plates 9 will approach each other through the force of the thrust spring 10, so that the clamping plates 9 can be clamped with the clothes, thereby preventing the hearing aid body 1 from falling off during use. The moving range of the moving block 8 is limited by the coordinated use of the limiting groove 11 and the limiting block 12, so as to prevent the moving block 8 from escaping from the slot 7, thereby improving the stability of the clamping plates 9 during use. By arranging a magnet 13 on the inner wall of the clamping plate 9, the magnet 13 can make the clamping plate 9 tighter during clamping. When the staff has finished clamping, the clamping plate 15 is moved downward so that the bottom of the clamping plate 15 can clamp the two clamping plates 9. The return spring 16 is set so that the clamping plate 15 can move downward quickly, making it more stable and quick for the staff to fix the clamping plate 9. The staff can turn the handle 20 to drive the round rod 19 and the take-up roller 17 to rotate, which is convenient for the staff to store the connecting line 5, thereby avoiding the situation where the connecting line 5 is too long and cluttered, and improving the convenience of using the connecting line 5. When the staff does not use the take-up roller 17, the position of the take-up roller 17 is limited by inserting the block 25 into the slot 24 starting from the front end of the first U-shaped block 4. At the same time, the elastic force of the connecting spring 23 makes the block 25 more stable when it is inserted into the slot 24.

[0031] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
