s2, putting feet on the stepping pad (18), fastening the feet by a tying belt (19), climbing a telegraph pole, extruding the friction pad (21) by the telegraph pole, driving the adjusting block (20) to rotate around the adjusting shaft (23), driving the adjusting gear (25) to rotate by the adjusting block (20), and enabling the adjusting blocks (20) on the left side and the right side of the adjusting shaft (23) to rotate at the same angle;

s3, when descending, the fastening motor (33) stops rotating, the fastening spring (39) drives the sliding rod (38) to reset due to extrusion, so that the fastening block (31) can rotate freely, the friction plate (16) loosens and rotates reversely outwards, and the gravity of people cannot be supported by the pedals;

s4: the transmission block (60) pushes hydraulic oil to enable the hydraulic oil (41) to rotate, the transmission block (45) is driven to shift (49), the tire (56) is enabled to be in contact with the telegraph pole, the pedal is used for changing sliding connection with the telegraph pole into sliding connection, and meanwhile, a sliding safety belt tied by a person drives the person to slide downwards to quickly reach the ground.
