1. A hinge structure, comprising:
a base having an axial hole, wherein an inner wall of the axial hole has a plurality of positioning concave portions;
at least one torque element disposed in the axial hole and comprising a torque providing portion and a plurality of positioning convex portions, wherein the torque providing portion surrounds a central axis of the axial hole to form a through hole, the torque providing portion has a fracture adjacent to the through hole, and the positioning convex portions are connected to the torque providing portion and configured to respectively correspond to the positioning concave portions, wherein the torque providing portion and the positioning convex portions are located on a same virtual plane, and the virtual plane is perpendicular to the central axis, a first virtual straight line on the virtual plane passes through the fracture and the central axis, at least some of the positioning convex portions are not located on the first virtual straight line, at least one of the positioning convex portions is located on the first virtual straight line, a distance between the at least some of the positioning convex portions and the fracture is smaller than a distance between the at least one of the positioning convex portions and the fracture, and a second virtual straight line on the virtual plane is perpendicular to the first virtual straight line and passes through the central axis, wherein a distance between the at least some of the positioning convex portions and the second virtual straight line is smaller than a distance between the at least some of the positioning convex portions and the at least one of the positioning convex portions; and a rotation shaft passing through the through hole, and wherein
the fracture is located on one side with respect to the second virtual straight line, and the positioning convex portions are located on another side with respect to the second virtual straight line.
