[0049] The coil spring 202c-2 is designed in multiple, by the setting of the coil spring 202c-2, the coil spring 202c-2 can be tightened and stored energy when the ratchet wheel 202c-1 rotates in one direction, and the stored energy can be released to automatically reverse and reset the ratchet wheel 202c-1 in subsequent operation.

[0050] The adjusting piece 202 further comprises a positioning rod 202d movably connected to the surface of the bearing frame 202a, the surface of the positioning rod 202d is fixedly connected with a pawl 202d-1 matched with the ratchet wheel 202c-1, and the surface of the positioning rod 202d is sleeved with a torsion spring 202d-2.

[0051] Through the arrangement of the pawl 202d-1 and the ratchet wheel 202c-1, only the single direction rotation of the ratchet wheel 202c-1 is allowed in the clamping state of the pawl 202d-1, and the reverse rotation is not allowed.

[0052] One end of the torsion spring 202d-2 is fixedly connected to the surface of the bearing frame 202a, and the other end of the torsion spring 202d-2 is fixedly connected to the surface of the pawl 202d-1.

[0053] Through the arrangement of the torsion spring 202d-2, the torsion force can be provided for the pawl 202d-1, and the pawl 202d-1 is prevented from being randomly rotated to be separated from the ratchet wheel 202c-1 without external force.

[0054] One end of the pawl 202d-1 extends to the outside of the bearing frame 202a, so that the pawl 202d-1 can be conveniently rotated to be separated from the ratchet wheel 202c-1, and the through slot 202a-2 provides space for the rotation of the pawl 202d-1.

[0055] The number of the ratchet wheels 202c-1 is two, and when the upper ratchet wheel 202c-1 rotates in the single direction counterclockwise, the lower ratchet wheel 202c-1 must rotate in the single direction clockwise. Through this design, when the driving friction pulley 202b contacts with the upper driven friction pulley 202c-3 and continues to rotate upward, the upper ratchet wheel 202c-1 cooperates with the pawl 202d-1 to complete the reverse locking, and in the same way, when the driving friction pulley 202b contacts with the lower driven friction pulley 202c-3 and continues to rotate downward, the lower ratchet wheel 202c-1 cooperates with the corresponding pawl 202d-1 to also complete the reverse locking.

[0060] When it is necessary to adjust the contact pressure of the arc plate 201a with the human body, the wearer can drive the driving friction pulley 202b to move upwards in the guide groove 202a-1 and contact the corresponding driven friction pulley 202c-3. At this time, the driving friction pulley 202b is continuously driven to rotate upwards, and under the cooperation of friction, the driven friction pulley 202c-3 will rotate, the coil spring 202c-2 will be tightened and stored, and the movable rod 202c will be rotated to further wind the nylon rope 201c-1 on the movable rod 202c, so as to pull the displacement block 201c into the fixed sleeve 201b, the second spring 201b-1 is compressed, the action stroke of the first spring 201a-1 is increased, and the supporting force of the arc plate 201a on the human head is reduced, thereby reducing the contact force of the arc plate 201a on the human head, achieving the purpose of adjusting the pre-tightening strength.

[0061] When it is necessary to adjust the length of the binding rope 203, the driving friction pulley 202b is driven to move downwards and contact the corresponding driven friction pulley 202c-3, and then the driving friction pulley 202b is continuously driven to rotate downwards, so that the corresponding movable rod 202c is rotated to further wind the binding rope 203, the coil spring 202c-2 is tightened and stored, and the secondary binding stroke of the binding rope 203 is adjusted to ensure the stability of wearing and be suitable for different people's use requirements.

[0062] When it is necessary to release the nylon rope 201c-1 and the binding rope 203 after adjustment, or when the hearing aid body 100 needs to be removed after wearing, the wearer only needs to contact the pawl 202d-1 with two fingers and pinch the two pawls 202d-1 inward, so that the pawl 202d-1 rotates around the positioning rod 202d, the torsional spring 202d-2 is tightened, one end of the pawl 202d-1 is separated from the ratchet wheel 202c-1, and under the reset force of the coil spring 202c-2, the two movable rods 202c are simultaneously rotated and reset to release the nylon rope 201c-1 and the binding rope 203. In actual operation, the corresponding pawl 202d-1 can also be driven to rotate, and then the nylon rope 201c-1 or the binding rope 203 can be selectively released alone, which is more in line with the actual use requirements.

[0063] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present application and are not limiting. Although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present application can be modified or replaced equivalently without departing from the spirit and scope of the technical solutions of the present application, and they should be covered in the scope of the claims of the present application.
