ABSTRACT:
A spring hinge is provided which includes a first member, a second member, a spring, a spring seat, a tensile adjustment seat, a tensile adjustment pin, a shaft, and two holding heads. The holding heads each include a hollow hat and a spring member fixed inside the hollow hat, the central portion of the spring member being inwardly concave and having a set of slots radially extending to form a set of claws and an opening whose diameter is slightly smaller than the diameter of the shaft. Thus, the shaft penetrating through the opening is pressed and secured by the claws so as to prevent any withdrawal of the shaft from the opening.
