    "1. A fixing device, which is adapted to be fixed on a structure, comprising: a connecting member having a base, a first bar, a second bar, and a third bar, wherein the first bar and the second bar are respectively engaged with two sides of the base, and the third bar is engaged with the base; a first fixing plate having a first body and two first sleeves, wherein the first body is adapted to be fixed on the structure; the first sleeves are connected to the first body, and respectively fit around the first bar and the second bar on two sides of the third bar, so that the first fixing plate is pivotable relative to the connecting member; a second fixing plate having a second body and two second sleeves, wherein the second body is adapted to be fixed on the structure; the second sleeves are connected to the second body, and respectively fit around the first bar and the second bar on two sides of the third bar, so that the second fixing plate is pivotable relative to the connecting member; and a hanging ring, which is engaged with the third bar in a rotatable manner.",
    "2. The fixing device of claim 1, wherein, on the first bar, one of the second sleeves is located between one of the first sleeves and the third bar; on the second bar, the other one of the first sleeves is located between the other one of the second sleeves and the third bar.",
    "3. The fixing device of claim 1, wherein the first bar and the second bar are located in an axial direction.",
    "4. The fixing device of claim 1, wherein the third bar is located between the first bar and the second bar.",
    "5. The fixing device of claim 1, wherein the first body and the second body respectively have a plurality of perforations; each of the perforations is adapted to be passed through by a fastener to fix the first body and the second body on the structure.",
    "6. The fixing device of claim 1, wherein the third bar has an axial neck, and the hanging ring has a perforation; a wall of the perforation surrounds the axial neck.",
    "7. The fixing device of claim 1, wherein the base, the first bar, the second bar, and the third bar of the connecting member are integrally made.",
    "8. The fixing device of claim 1, wherein one side of the first body extends to form two ribs; the ribs are bent by stamping to become the first sleeves.",

  "description_excerpt": "1. Technical Field\n\nThe present invention relates generally to a safety fixing device, and more particularly to a fixing device which is suitable for high-altitude operations.\n\n2. Description of Related Art\n\nAccording to the regulations regarding occupational safety and health (OSH) and equipment standards for safety and health in the construction industry, if there is a risk of falling during operations, the employer should take appropriate measures to prevent accidents and to ensure the safety of workers. Safety belts are commonly used in high-altitude operations to “stop” the falling. Therefore, the fixing strength of a safety belt is critical for determining whether the safety belt could provide its effectiveness. A common way to fix a safety belt is by providing a fixing device on the roof of the construction site, and an end of the safety belt is connected to the fixing device, while another end thereof is connected to the worker, whereby to protect the worker from falling accidents.\n\nDuring a high-altitude operation, the design of a safety fixing device would also affect the efficiency and convenience of a worker. For instance, a conventional fixing device usually includes a ring used for connecting a safety belt, and the ring is not rotatable. Therefore, while the worker is moving around, the safety belt might wind around the fixing device, which seriously affects the movements of the worker, and confines his moving range.\n\nIn light of this, the conventional fixing devices still have room for improvements.",
