external force of the fixture block 514 loses the clamping with the clamping groove 511, the threaded rod 51 resets under the action of the torsion spring 517, the user presses the middle part of the clamping rod 3 to force the clamping rod 3 to deform and drive the threaded rod 51 and the connecting block 52 to move towards two sides along the guide groove 533 through the guide block 532, at the moment, the air bag 521 extends towards two sides along with the moving connecting block 52, the baffle 529 is vertical to the air guide groove 524 under the action of the spring hinge 5292 in an initial state, when the air bag 521 extends towards two sides, the air pressure inside the air bag 521 is too small, the air can extrude the baffle 529 into the air bag 521 through the air guide groove 524, so that the air bag 521 between the two groups of connecting blocks 52 is inflated, the distance between the two groups of connecting blocks 52 is increased, the clamping rod 3 is forced to further clamp the human ear to improve the clamping effect, the baffle 529 divides the air guide groove 524, the inner diameter of the upper half section of the air guide groove 524 is smaller than that of the lower half section, a rubber pad 5291 is arranged on one side of the baffle, which is close to the air guide groove 524 with the smaller inner diameter, when a user feels that the clamping force is too large, the connecting rod 5283 is pressed, the reset block 5281 in the reset groove 5282 drives the magnet 5286 to move downwards, the magnet 5286 moving in the reset groove 5282 adsorbs the fixture block 514 to force the fixture block to lose the clamping effect on the clamping groove 511, the threaded rod 51 is rotated and reset under the matching of the torsion spring 517 and the rotating rod 516, so that the clamping rod 3 is forced to rotate by taking the connecting groove 41 as a midpoint, the clamping force of the clamping rod 3 is reduced, meanwhile, under the matching of the plastic rod 7 and the connecting rod 5283, the plastic rod 7 resists the baffle 529 and turns over by taking the spring hinge 5292 as a midpoint, at the moment, gas in the air bag 521 overflows, the distance between the two groups of the connecting blocks 52 is reduced, and the reset block 5281 reciprocates in the reset groove 5282 under the action of the reset spring 5285, therefore, a user can finely adjust the clamping force of the clamping rod 3 by pressing the connecting rod 5283, and further improve the wearing comfort of the user, the continuous operation of the reset assembly 528 is ensured by the through hole 5284 formed in the upper end of the reset block 5281, the user can press the clamping rod 3 to be close to the position of the Bluetooth headset main body 1 to drive the adjusting rod 21 to stretch and retract in the adjusting block 22, meanwhile, the position of the adjusting rod 21 is fixed in the adjusting block 22 under the matching of the pressing block 24, the pressing groove 26, the pressing spring 23 and the tooth groove 25, under the matching of the Bluetooth headset main body 1 with the adjusting rod 22 and the adjusting block 21, the angle of the Bluetooth headset main body 1 deflects, so that the clamping effect of the headset is further improved, the adjusting ring 67 is twisted by the user, and under the matching of the limiting block 65 and the limiting groove 66, the adjusting ring 67 drives the sound insulation pad 61 to rotate around the Bluetooth headset main body 1, the fan-shaped gives sound insulation and fills up a 61 and gives sound insulation and fill up two 62 coincidence each other, thereby make outside air through give sound insulation fill up a 61 and give sound insulation fill up two 62 coincidence back void inflow human ear wearing department that produces, and then increase the mobility of air, rotatory adjusting ring 67, make and adjusting ring 67 fixed connection give sound insulation fill up a 61 and give sound insulation and fill up two 62 dislocation with giving sound insulation, slider 63 and spout 64 mutually support down and under the centre gripping of holding rod 3 this moment, give sound insulation and fill up two 62 movements along spout 64, give sound insulation and fill up the inboard of a 61 and give sound insulation and fill up two 62 outside contact and paste each other tightly under the centre gripping of holding rod 3 this moment, form a relative sealed state, thereby the syllable-dividing effect of earphone has been improved, further user's use experience has been improved.
