step two: after the sliding roller (9) falls to the bottommost end of the lower chute channel (25), the bottom intervals of the two groups of supporting legs (3) on the same side are supported by the positioning rod (7) to be fixed, so that the supporting legs (3) cannot rotate, the positions of the supporting legs (3) are fixed, and then the bed body (2) is pushed to move the portable carrying sickbed;

step three: when the portable carrying sickbed is transported to other sickbeds or operating tables, the handle (15) is pulled to enable the handle (15) to rotate around the control shaft (22), the control shaft (22) rotates to drive the supporting rod (23) to rotate, the supporting rod (23) rotates around the control shaft (22) to drive the supporting wheel (21) at the far end to lift up, one end of the conveying plate (1) is jacked up, meanwhile, the control rod (14) is clamped into the limit hook (16) on the lower surface of the bed body (2), the control rod (14) is prevented from being reset by the horizontal end of the bottom end of the limit hook (16), then the handle (15) at the other end is pulled, the supporting rod (23) at the side also drives the supporting wheel (21) to lift up, and all the two ends of the conveying plate (1) are jacked up;

step four: pushing the transport plate (1) to enable the lower surface of the transport plate (1) to move above the supporting wheels (21), integrally sliding the transport plate (1) onto other sickbeds or operating tables, enabling one end of the transport plate (1) to be in contact with the sickbeds by the sliding wheels (4) at one end of the transport plate (1) when contacting with other sickbeds, enabling one end of the transport plate (1) to move on the sickbeds, and completing integral transfer of the transport plate (1) without moving patients;

step five: when the supporting leg (3) is folded after the carrying is finished, the sliding roller (9) is contracted inwards by rotating the recycling screw (26) to separate from the range where the reverse blocking block (11) is located, then the supporting leg (3) is folded, the lower chute channel (25) extrudes the sliding roller (9) in the folding process of the supporting leg (3), and the sliding roller (9) is forced to move upwards, so that the supporting leg (3) is folded.
