The retarders and the gripper blocks are hingedly connected to one of the holders. A plurality of grippers are provided on the holders and the retarders. The hydraulic cylinder is fixed to one of the holders. The press part is fixed to the hydraulic cylinder. The crank seat is fixed to the hydraulic cylinder. The crank lever is slidably located in the crank seat. The hydraulic cylinder is actuated by the crank lever to allow the press part presses the gripper blocks and the grippers on one of the retarders such that the rope is crossly clamped in S shape to retard the descending speed.
