Abstract
The spring box contains a base piece, a front plate, a back plate, a rotational piece, and a torsion spring. The base piece and the front and back plates have aligned through holes. A radial gap is configured on the rim of the base piece. The rotational piece has a curved sliding element along a section of the circumference. The sliding element has a groove, a weight block configured at one end of the sliding element, and a notch at the other end. The rotation piece is placed in the through hole of the base piece. The two ends of the torsion spring are embedded in the gap and the notch. The rotational and base pieces are sandwiched between the front and back plates. Then, by the weight of the weight block and the resilience of the torsion spring, a door handle is restored to its default position after being turned.
