The tightness adjusting unit comprises a shell 6 for enabling the movable ends of the two head belts 5 to pass through in an overlapped mode, an adjusting gear 7 which is positioned in the shell 6 and is correspondingly meshed with the movable ends of the two head belts 5, and an adjusting knob 8 with a rotating shaft 81 penetrating into the shell and the rotating shaft 81 and the adjusting gear 7 being fixed coaxially; the headband 5 comprises an elastic section 51 forming a fixed end of the headband 5 and a plastic section 52 forming a movable end of the headband 5; the two plastic sections 52 are respectively provided with a long groove 53 for the adjusting gear 7 to pass through and extend along the extending direction of the plastic sections 52; the two long grooves 53 are correspondingly meshed with the adjusting gear 7, and the two head belts 5 move in opposite directions under the tooth meshing transmission of the adjusting gear 7. The plastic section 52 facilitates the provision of a rack structure cooperating with the adjusting gear 7. The two long grooves 53 are respectively provided with a rack structure on the opposite side walls to perform tooth meshing transmission with the adjusting gear 7, and when the adjusting gear 7 rotates, the two long grooves 53 are driven to move along the opposite directions, so that the tightness adjustment of the headband 5 is realized.

And a pin shaft 9 coaxially penetrating through the adjusting gear 7 and the rotating shaft 81 is arranged in the shell 6.

The pressure display component 4 is movably embedded in the main body of the adjusting knob 8 and is fixed with the pin shaft 9; the adjusting knob 8 is provided with a transparent window 82 for watching the pressure display assembly 4; the pin 9 is provided with an axial through hole 91 for passing the electrical conductor 41 of the pressure display assembly 4.
