The invention discloses a synchronous gradually-changing pressing rope clamping friction energy absorber for an inclined shaft sliding-down protection device. The synchronous gradually-changing pressing rope clamping friction energy absorber comprises a main steel wire rope, a lower clamping plate, an upper clamping plate, a floating pressing unit, a plurality of gradually-changing pressing devices, a rope-driven rotating device and a machine shell. The rope-driven rotating device comprises a gear shaft only capable of rotating, a rope storage disc wheel fixed to the top end of the gear shaft, and a thin steel wire rope fixedly connected to the rope storage disc wheel and stored around the rope storage disc wheel, and the other end of the thin steel wire rope is fixedly connected with the main steel wire rope; the gradually-changing pressing device comprises a double-thread shaft and a large gear which is coaxially connected to the double-thread shaft in series and meshed with the gear shaft, and the large gear is coaxially matched with a guide section of the double-thread shaft in a sliding mode and transmits torque. When the sports car is braked, the main steel wire rope is pulled and drives the thin steel wire rope to move so as to drive the gear shaft to rotate, then all the large gears are synchronously driven to enable all the double-thread shafts to rotate and axially move, and then the overall pressing plate is synchronously driven to slowly and downwards press the spring. Therefore, the friction braking force of the main steel wire rope is slowly increased.
