The hook 1 in this embodiment is designed with the stress detection unit 13 composed of the rotating arm 131 and the trigger 132 to detect the stress state of the hook 1, so as to provide a signal for the operator to determine whether the hook is stressed, and ensure the safety of the operator. In this embodiment, the specific shape of the hook body 11 is not limited, and the movable engaging member 12 is not limited, as shown in fig. 1, which is an embodiment of the present invention. In this embodiment, the hook body 11, the movable engaging member 12 and the first rotating shaft 14 form a closed loop structure for hooking an object. As shown in fig. 3, when the hook 1 is hung, the hook 1 receives an upward supporting force F of the hung object due to the downward gravity of the worker, and the curved portion 113 of the hook body 11 is located at the uppermost portion of the entire structure of the hook 1, the rotating arm 131 at one side of the bending part 113 is rotated clockwise around the second rotating shaft 15 by the supporting force, and since the triggering member 132 at the outer side of the first connecting part 111 of the hook body 11 is fixed to the rotating arm 131 as one body, therefore, the trigger 132 rotates clockwise around the second rotating shaft 15, and the trigger 132 contacts the outer side of the first connecting member 111 to generate a force signal, when the hook 1 is not hung, the above-mentioned vertical upward supporting force F is not generated, the rotation arm 131 is not rotated, the triggering member 132 is not in contact with the outside of the first connecting member 111, and a force signal is not generated.
