[0007] The second easy tear line hole is formed in the middle of the bottom of the tear gap, and the second easy tear line hole penetrates to the bottom of the nose pad and the face pad, and the second easy tear line hole is used to realize the separation operation of the nose pad and the face pad, so as to realize the independent use of the nose pad or the face pad.

[0008] As a further scheme of the utility model: the nose pad, the face pad is by surface layer, polyurethane pressure relief layer, viscose layer, release paper is composed, the surface layer, polyurethane pressure relief layer, viscose layer, release paper is sequentially adhered and is distributed from top to bottom.

[0009] As a further scheme of the utility model: the tear gap, tear piece, first easy tear line hole are integrally formed by punching operation from surface layer.

[0010] As a further scheme of the utility model: the second easy tear line hole is formed on the upper surface of polyurethane pressure relief layer and sequentially penetrates viscose layer, release paper.

[0011] As a further scheme of the utility model: the two groups of first easy tear line holes of the two arc-shaped edges of tear piece are staggered distribution along arc track, and the second easy tear line hole is distributed in the middle region of tear piece.

[0012] Compared with the prior art, the utility model has the beneficial effects that:

[0013] By setting the detachable nose pad and face pad structure, the pressure relief pad has two use methods: one is overall use, and one is that the nose pad and face pad are detached and used alone, so that the use of the pressure relief pad is more flexible, and the use demand of different personnel can be better adapted.
