Abstract
A breathing mask has a mask body, a mounting bracket and a universal connecting tube. The mask body has a first universal socket bracket having a first spherical recess. The mounting bracket is mounted on the mask body and has a second universal socket bracket having a second spherical recess. The universal connecting tube is mounted universally pivotally in the mask body and has a ball joint mounted universally rotatably in the first and second spherical recesses. The universally rotating ball joint allows a breathing tube connected to the universal connecting tube to pivot to any orientations and prevents the breathing tube from over bending.
