In the process of pulling the rubber belt 10, the spring spring 9 undergoes elastic deformation, and the upper headband 3 is set on the back of the victim's head. The lower headband 3 fits the victim's lower jaw. The headband 3 is tightly pressed against the victim's head and lower jaw by the elastic restoring force of the spring spring 9. Compared with the traditional elastic band, the spring spring 9 can provide a greater elastic restoring force, thereby tightly fixing the earphone 2 on the victim's head. After that, the rescuer toggles the movable bar on the movable opening 11, pushes the movable bar 12 to slide on the movable opening 11 toward the side of the rotating rod 7, and the movable bar 12 is disengaged from the one side snap-in 13 and moved to the other snap-in 13 for snap-in fixation. The snap-in assembly 23 is a spring and a clamping block in the prior art. The movable bar 12 moves to drive the elastic telescopic rod 14 and the arc plate 15 to move in the mounting plate 4. After the elastic telescopic rod 14 moves, the arc plate 15 is pressed on the rotating rod 7, so that the snap-in teeth 16 on the arc plate 15 fit with the snap-in teeth 16 on the rotating rod 7, so that the rotating rod 7 cannot rotate, thereby limiting the position of the headband 3, so that the headband 3 will not easily move forward and backward, causing slippage, further improving the wearing stability of the headset 2, and the display 1 plays the virtual reality picture after wearing, and the headset 2 plays the hypnotic sound to hypnotize the disaster victims; The movable bar 12 moves to drive the latch teeth 16 on the arc plate 15 to fit with the latch teeth 16 on the rotating rod 7. In the process of completing the limit of the rotating rod 7, the connecting rod 19 drives the plate 18 to move in the pad 17. The plate 18 moves to push the sound insulation cotton in the pad 17 closer to the ear of the disaster relief worker. Since the plate 18 is set as an arc surface and is made of rubber, the plate 18 is further bent and fits the ear by the force of the ear, thereby further improving the wearing stability of the earphone 2 during the rescue process. When the rescuer pulls or pushes the vertical block 212 to vertically lift on the sleeve 211, the hinged rod 213 hinged to the vertical block 212 can be used to push or pull the adjustment block 20 to move horizontally on the display 1. The horizontal movement of the adjustment block 20 drives the horizontal plate 6, the connecting plate 5 and the earphone 2 to move horizontally, and the distance between the earphones 2 can be quickly adjusted. After the disaster relief personnel put on the earphones 2, they can directly push or pull the display 1 to make the connecting plate 5 slide on the horizontal plate 6, and the distance between the earphones 2 and the display 1 can be quickly adjusted according to the needs of the disaster relief personnel in different situations to adapt to different head shapes. The rubber strip 22 can provide damping for the sliding of the connecting plate 5 and the vertical block 212 to avoid easy sliding. After the earphone 2 is fixed, the rescuers hold the disaster victims and move them to quickly evacuate the dangerous area. When the disaster victims move and evacuate quickly, the earphone 2 worn stably can effectively reduce the risk of the earphone 2 shaking or slipping during movement, and can provide a more stable wearing effect.
