The limited shock-absorbing pad 2 is only arranged at the right end of the fixing seat 1, and there is no such pad at the left end.

[0040] Working principle: When the relevant personnel need to lift the carbon fiber board 15, the locking button 4 is first moved inward and the connecting spring 3 is squeezed when the locking button 4 moves, thereby releasing the locking limit between the locking button 4 and the card slot B17, and then the front end of the carbon fiber board 15 is manually held and the carbon fiber board 15 is flipped upward, so that the card slot A16 corresponds to the locking button 4. At this time, due to the elasticity of the connecting spring 3, the locking button 4 is reset, and then the outer wall of the locking button 4 is engaged with the card slot A16. At this time, the carbon fiber board 15 is in the purpose of flipping open, and at this time, due to the reset engagement of the locking button 4, the carbon fiber board 15 can be fixed to prevent the carbon fiber board 15 from rotating.

[0041] When the carbon fiber plate 15 and the face mask on the helmet body 14 need to be disassembled, the anti-slip screw 7 is first rotated to release the limit of the anti-slip screw 7 on the fixing seat 1, and then the anti-slip screw 7 is moved to the right end, thereby allowing the shoulder screw 6 to rotate to release the limit of the shoulder screw 6 on the rotating pressure plate 5. After releasing the limit, the rotating pressure plate 5 is rotated to Figure 7 state, and then the two sets of round holes on the carbon fiber plate 15 can be separated from the left and right rotating shafts on the fixing seat 1 and the helmet body 14, and then the carbon fiber plate 15 and its mask can be removed, and then the corresponding rotating shaft shock-absorbing ring 9 and the limiting shock-absorbing pad 2 can be disassembled and replaced. The installation operation is the opposite of the above operation.
