It is also a matter of safety.

摘要

The invention relates to a heavy patient hanging on one end of a safety hook to hang Burroughs (1). The safety hook includes a base (5) connected or embedded in the hanging barbell (1).A state (2) hook load state is displayed by a rotating base (5) to allow the hook to move in a state (2) horizontally at Mel An open closed position and state free end hook between the S hook (2) involves the state base (5) at a point of epsilon Mu PI lambda Kappa (15).The state linkage (2) is formed, and thus forced into a closed position, exerting downward force and a n. A is applied to this batch when opening position. Resource constraints remain in state (2) the hook is open and closed unless an important force of the hook is applied in the state.
