Abstract
Claims
1. A multi-strand spring structure, comprising: A single wire is formed by three cables spirally wound together. The wire has a first part, two second parts, two third parts, two fourth parts, a first end, and a second end. The wire is arranged in the following order from the first end to the second end: the first part, one of the second parts, one of the third parts, the two fourth parts, another third part, and another second part. The wire is further divided into a plurality of first loops, a plurality of second loops, a plurality of third loops, and a plurality of fourth loops corresponding to the first part, each of the second parts, each of the third parts, and the fourth part. The diameter lengths are arranged in the following order from shortest to longest: each of the first loops, each of the second loops, each of the third loops, and each of the fourth loops.
2. The multi-strand spring structure as described in claim 1, wherein, There is a first gap between the connected first part and the second part, a second gap between the connected second part and the third part, a third gap between the connected third part and the fourth part, and a fourth gap between each fourth part. The length of each fourth gap is greater than the third gap, the length of the third gap is greater than the second gap, and the length of the second gap is greater than the first gap.
