Move within the itinerary. After blocking gear plate 76 bites, if crown block lifts and slides hanger and continues to slide, the gear of steel quality blocks gear plate 76 will rub against the rubber rack block 311 below and play a certain blocking effect. When the inertial energy is too large and the blocking force cannot stop the sliding, the gear plate will force the rack to move downward, and it can only move out of engagement.
