The size of the guide rail slot fixing hole and the spacing in the slot of the standard protective helmet body 13 are fixed standards. The guide groove connector 4 can slide smoothly into the guide groove of the tactical rail 11. After the guide groove connector 4 slides into the guide groove of the tactical rail 11, it is necessary to use both hands to press the quick release paddle head 9 on the quick release paddle 5 to slide back and forth, adjust it to a suitable position, release the quick release paddle head 9 and shake it slightly back and forth. When you hear a sound, it is confirmed that the fixed hole embedding module 8 has been embedded in the fixed hole of the tactical rail 11, which proves that the guide groove connector 4 has been installed. When disassembling, you only need to press both sides outward with both hands at the same time, the quick release paddle head 9, so that the fixed hole embedding module 8 is separated from the fixed hole, and then push it evenly in the direction of the protective helmet body 13 to easily remove the mask quick release system. Therefore, bolts can be installed inside the anti-dismantling screw hole 18 as needed, so that the fixed hole embedding module 8 can be resisted by the bolts installed inside the anti-dismantling screw hole 18, thereby preventing the control function of the quick-release paddle head 9, and the fixed hole embedding module 8 is always embedded in the fixed hole of the tactical rail 11, so that the control function of the quick-release paddle head 9 is invalid. This is a preset mechanism to prevent the mask from being quickly removed by external force, which provides users who need to prohibit quick removal with an operation option, and the pin head part of the mask bracket indexing pin component 7 is correspondingly ejected into the indexing pin groove 17 at different heights of the mask bracket 3, so that the mask bracket 3 can rotate with the screw penetration threaded connection with the guide rail groove connector 4 as the center of the circle, thereby realizing the function of the mask 10 hovering at a specified angle (position).
