The fixing frame 502 is fixed on the receiving cover 2 of the breathing mask. When the wearer connects the receiving cover 2 to the wearer's mouth and/or nose, the forehead support frame 501 will contact the wearer's forehead. Due to the different protruding heights of the foreheads of different wearers, the set angle between the forehead support frame 501 and the receiving cover 2 may not be suitable for all wearers. Or swing the forehead support frame 501 away from the wearer's forehead so that it is suitable for different wearers. Specifically, when the required angle between the forehead support frame 501 and the receiving cover 2 is greater than the set angle (that is, the wearer's forehead is more protruding), the forehead will promote the forehead support frame 501 to expand the set angle; When the desired angle between the forehead support frame 501 and the receiving cover 2 is smaller than the set angle (ie the wearer's forehead is lower), the headband will actuate the forehead support frame 501 to reduce the set angle. It can be seen from this that the frame 5 of the present invention can realize the automatic adjustment of the forehead support frame 501 without manual auxiliary adjustment. Wherein, when the forehead support frame 501 swings relative to the fixed frame 502 , the connecting piece 503 is equivalent to a hinge to allow the forehead support frame 501 and the fixed frame 502 to swing relative to each other.
