Abstract
The utility model discloses a thin-type spring sheet structure assembly. The assembly comprises a welding plane, a U-shape folding portion which is formed through upwardly bending one end of the welding plane, an adsorption plane which is formed through extending the U-shape folding portion and a contact portion which is formed through upwardly extending the adsorption plane. A width of the contact portion is less than a width of the adsorption plane. One end of the adsorption plane, which is close to the contact portion, forms two symmetrical steps. Each step possesses a first step surface which is close to the contact portion and a second step surface which is adjacent to the first step surface. One side of the second step surface, which is far away from the U-shape folding portion, is extended and provided with a carrying portion.
