Single-strand spring structure

Abstract

This novel single-strand spring structure includes: a wire body, which is helically wound, having a first end and a second end. The first end and the second end are connected by a plurality of spring coils, each spring coil being further divided into a plurality of first coils, a plurality of second coils, and a plurality of third coils. The diameters of the aforementioned coils, from shortest to longest, are sequentially designated as first coils, second coils, and third coils. Each spring coil gradually expands from the first end and the second end toward each other, sequentially designated as first coils, second coils, and third coils. By designing the wire body to be narrow at the top and bottom and wide in the middle, the problem of the spring coils being squeezed to the sides during compression, affecting the surrounding wire body, and thus preventing them from tangling together can be effectively avoided.

Claims
