A handle structure includes a handgrip body and at least one rotating body. The rotating body is pivotally connected to the handgrip body, the rotating body is used to pivotally connect a first object, and when rotating, the rotating body drives the handgrip body to move toward the first object for reducing the height of the handle structure. Therefore, the handle structure can make a handgrip body moved out toward a direction distant from the first object when used, and can make the handgrip body moved in toward a direction of the first object when not in use for reducing the height of the handgrip body so as to operate and use easily and prevent collision.
