In order to ensure smooth adjustment of the adjusting rack, a limit chute 314 is provided on the support portion 311 , and the limit chute 314 is used to limit the moving direction of the first adjusting rack 8 and the second adjusting rack 9 .

The adjusting rack includes a first adjusting rack 8 and a second adjusting rack 9, and the first adjusting rack 8 and the second adjusting rack 9 are relatively movable. The first adjustment rack 8 and the second adjustment rack 9 have teeth.

The first adjusting rack 8 and the second adjusting rack 9 are part of the headband, or the first adjusting rack 8 and the second adjusting rack 9 are respectively connected with the headband. The first adjustment rack 8 and the second adjustment rack 9 are located at least partially within the housing.

The clamping structure includes a first clamping structure 4 and a second clamping structure 5, and the first clamping structure 4 and the second clamping structure 5 are located in the casing. The first clamping structure 4 and the second clamping structure 5 are rotatably connected, the first clamping structure 4 is in a state of being engaged with or disengaged from the first adjusting rack 8 , and the second clamping structure 5 is engaged with the second adjusting rack 9 . Engaged or disengaged state. When the clamping structure and the adjusting rack are in an engaged state, the headband is fixed and cannot be adjusted, and when the clamping structure and the adjusting rack are in a separated state, the headband can be adjusted.

The structures of the first clamping structure 4 and the second clamping structure 5 are similar, and the first clamping structure 4 is taken as an example for description:

The first clamping structure 4 includes a connecting arm 41 and a clamping arm 42 arranged at a certain angle. The connecting arm 41 is provided with a shaft hole 411 , and the shaft hole 411 is used for connecting with the rotating shaft 11 on the button 1 . There are two connecting arms 41 , the two sides of the button 1 are respectively provided with the rotating shafts 11 , and the two connecting arms 41 are respectively assembled with the rotating shafts 11 located on both sides of the button 1 . The end of the clamping arm 42 is provided with a hook portion 421 which is matched with the rack.

The reset member 6 is used to connect the first clamping structure 5 and the second clamping structure 6, so that the first clamping structure 5 and the first adjusting rack 8 are in an engaged state, so that the second clamping structure 6 and the The second adjusting rack 9 is in the meshing state.

The reset member 6 is a reset spring, and the reset member 6 is connected to the clamping arm 42 of the clamping structure. Wherein, the reset member 6 and the rotating shaft 11 of the button 1 are in a vertical state, so as to ensure the best reset effect and improve the service life of the reset member 6 . Of course, the reset member 6 can also be realized by other elastic members.

Button 1, the button 1 is used to press the first clamping structure 4 and the second clamping structure 5, so that the first clamping structure 4 and the first adjusting rack 8 are in a separated state, so that the second clamping structure 5 and the second clamping structure 5 are separated from each other. The adjusting rack 9 is in a disengaged state. A button hole 21 is opened on the headband rear shell 2 , and the button 1 is located in the button hole 21 .
