If the user feels that the headband is too loose or too tight to wear after wearing the head-mounted device, the button 1 can be pressed to adjust. The clamping structure and the adjusting rack are in a separated state by pressing the key 1, as shown in fig. 4, so that the adjusting rack is in a free moving state, at the moment, the adjusting rack can adjust the tightness of the headband according to the size of the head of a user, the key is released after the adjustment is finished, and the clamping structure and the adjusting rack are in an engaged state under the action of the reset piece, so that the headband is in a fixed state.
Specifically, if the headband is sensed to be too loose, the user wants to tighten the headband, presses the key 1 to move the mounting plate 12 of the key 1 in the limiting groove 315 of the headband front shell 3, the key 1 approaches the headband front shell 3, the reset piece 8 is compressed, meanwhile, the two rotating shafts 11 on the key 1 drive the connecting arms of the clamping structures to approach the headband front shell 3 together, and the two clamping structures are blocked by the first shaft 312 and the second shaft 313 respectively, so that the hook 421 of the clamping structure is separated from the tooth of the adjusting rack. At this time, the two adjusting racks can be adjusted to move towards the middle, after the user feels the tightness is proper, the key 1 is loosened, and under the action of the elastic force of the reset piece 6, the hook-shaped part 421 of the clamping structure is clamped into the tooth-shaped part of the adjusting racks again, so that the tightness of the headband is fixed.
