Abstract
A socket structure includes a main body provided with a mounting element. The mounting element includes six drive portions and six receiving portions. Each of the six drive portions includes a first face and a second face. The first face and the second face have an intersection provided with a first intersecting line. The first face and the second face intersect at a straight line. Each of the six receiving portions is an arcuate concave face. In a two-dimensional view, the mounting element has an axis provided with a first center, a first circle, a first hexagon, a first vertical line, six first angled corners, and a first distance, and the first center constructs a second circle, a second hexagon, six second angled corners, a second distance, and a first angle.
