The invention discloses a bus telescopic handrail based on an air compression buckle. The handrail comprises a fixed seat. A fixed cavity is formed in the bottom of the fixed seat; and the bottom of the inner wall of the fixed cavity is fixedly connected with a first supporting plate and a second supporting plate with respect to a central symmetry position. One side of the first supporting plate and one side of the second supporting plate are both connected with winding shafts in a penetrating and rotating mode through rotating bearings. The parts, located on the inner sides of the first supporting plate and the second supporting plate, of the winding shafts are fixedly connected with telescopic belts. And a clockwork spring is fixedly connected to the end, away from each winding shaft, ofeach telescopic belt, a supporting shaft is fixedly connected to the center of one side of the clockwork spring, and the end, away from the clockwork spring, of the supporting shaft is fixedly connected with the first supporting plate. The handrail relates to the technical field of bus accessories. According to the bus telescopic handrail based on the air compression buckle, vibration of the handrail can be reduced, the height of the handrail can be adjusted at will, and the bus telescopic handrail is suitable for people with different heights and safer and more reliable to use.
