1. A flat wiredrawing mattress, comprising
a top piece,
a bottom piece,
a side piece enclosed between a peripheral edge of the top piece and a peripheral edge of the bottom piece,
a hermetic air chamber formed between the top piece, the bottom piece and the side piece, and
a wiredrawing structure between the top piece and the bottom piece, wherein
the side piece comprises a tension connecting piece group configured to form a flattened surrounding surface of the mattress,
the tension connecting piece group comprises a first tension connecting piece, a second tension connecting piece, a third tension connecting piece and a fourth tension connecting piece,
the first tension connecting piece is on an upper side of the side piece,
both sides of the first tension connecting piece are connected with the side piece,
the fourth tension connecting piece is on a lower side of the side piece,
both sides of the fourth tension connecting piece are connected with the side piece,
two sides of the second tension connecting piece are respectively connected with the first tension connecting piece and the side piece,
two sides of the third tension connecting piece are respectively connected with the fourth tension connecting piece and the side piece,
a first inflatable space is between the first tension connecting piece and the side piece,
a second inflatable space is between the fourth tension connecting piece and the side piece,
the second tension connecting piece is connected to the third tension connecting piece and is welded to a middle of the side piece,
a third inflatable space is between the second tension connecting piece and the first tension connecting piece and the side piece,
a first air cell having a triangular cross section is defined by the second tension connecting piece, the first tension connecting piece, and the side piece,
a fourth inflatable space is between the third tension connecting piece and the fourth tension connecting piece and the side piece,
a second air cell having a triangular cross section is defined by the third tension connecting piece, the fourth tension connecting piece, and the side piece,
the side piece comprises a first air hole, a second air hole, a third air hole and a fourth air hole that respectively connect the air chamber with the first inflatable space, the second inflatable space, the third inflatable space and the fourth inflatable space, and
the wiredrawing structure is composed of wiredrawing threads of consistent length between the top piece and the bottom piece with an evenly distributed density that ensures balanced forces on the top piece and the bottom piece and results in the top piece and the bottom piece being flat.
