Abstract
A hinge structure includes a shaft, a first locking member, a second locking member, a third locking member and an elastic element. The first locking member, the second locking member and the third locking member are all disposed on the shaft, wherein the first locking member, the second locking member and the third locking member rotate with the shaft as an axis. The elastic element is sleeved on the shaft, wherein a first side edge of the elastic element leans against the second locking member, and a second side edge of the elastic element leans against the third locking member to provide an elastic force between the second locking member and the third locking member, thereby maintaining or restoring a pivoting angle of the second locking member and the third locking member with respect to the axis.
