After aligning the front-brain wearable part 11 with the adjusting tube 3 and wearing it on the user's head, the adjusting belt 8 bypasses the user's head and makes the inner teeth 801 engage with the spur gear 301. After the bottom of the adjusting belt 8 is received inside the locking member 6, the adjusting belt 8 is toggled to make the spur gear 301 rotate, thereby completing the adjustment of the rear-brain wearable part 12 and the front-brain wearable part 11 and completing the wearing.

An outer card slot 4011 is provided on the outer wall of the connecting rod 401, and a block 4012 is welded to the end of the connecting rod 401. The opening height between the locking rods 4 is greater than the anti-slip strip on the outside of the adjusting belt 8. After pulling the locking rod 4 outwards, the adjusting belt 8 can rotate. After the adjustment is completed, the connecting rod 401 is pushed back to its original position through the reset snap ring 7 to fix the adjusting belt 8 and make the adjusting tube 3 unable to rotate, realizing stable wearing.
