With the above overall configuration, when the user is normally walking at a high altitude, the lifeline 40 can be linked to the rotating drum 30, and the rotor 50 can be rotated around the central axis 80, so that the lifeline 40 can be normally stretched, but when the user falls, The instantaneous stretching of the free end of the lifeline 40 is used to apply an instantaneous centrifugal force to the two biasing members, so that the two centrifugal blocks 61 can overcome the return spring 62 and the outward bias of the through hole 53 and the pivot portion 611 as a fulcrum. When the crank 612 abuts against the blocking arm 55 and the latching portion 613 abuts against the closed end of the beak-shaped brake block 18, the centrifugal block 61 is locked between the brake block 18 of the outer casing 10 and the arm 55 of the rotor 50. The lifeline 40 is locked by making the rotor 50 unrotatable, thereby achieving a safe fall arrest function.

Therefore, in the quality inspection of the present invention, when the free end of the lifeline 40 is instantaneously stretched, it can judge the quality by locking the lifeline 40. If an abnormal condition occurs, it can be removed without disassembling the outer casing 10. The centrifugal block 61 of the biasing member is directly detected on the outside of the casing 10 through the window 17, so as to quickly determine the problem and find a solution as soon as possible, thereby improving and controlling the quality, thereby improving the existing defense. The pendant is inconvenient in the quality inspection.
