[0002] Sometimes in reality, bomb disposal operations are required. When bomb disposal personnel are moving, removing, and destroying explosives, they need to wear special high-protection helmets, and the helmets have locking mechanisms to lock the masks.

[0003] However, the existing locking mechanism for the visor of the explosive disposal helmet has the following disadvantages:

[0004] (1) The existing locking mechanism of the visor of the explosive ordnance disposal helmet has a weak quick locking function. When in use, the wearing speed needs to be increased, and the locking process of the traditional device is relatively complicated, which affects the normal progress of explosive ordnance disposal;

[0005] (2) The existing locking mechanism of the visor of the bomb disposal helmet has a weak demisting function. When in use, due to the high water vapor content in the air, water droplets are easily generated on the surface of the mask, which will affect visibility and cause blurred vision.
