The implementation principle of the embodiment is as follows:

when the infusion bottle or bag on the hook 26 needs to be replaced, the push plate 74 is kicked, and the push plate 74 pushes the air release tube 63 to slide along the release ring 62 toward the elevator tube 2. Since the gas discharging pipe 63 is opened with the discharging hole 64, pushing the gas discharging pipe 63 enables the internal cavity of the elevator tube 2 to communicate with the outside through the discharging hole 64 of the gas discharging pipe 63, so as to discharge the air in the elevator tube 2. After the high-pressure air in the lifting pipe 2 is released, the air pressure in the lifting pipe 2 falls, and the lifting rod 22 also falls along with the air pressure, so that a nurse can conveniently replace the infusion bottle or the infusion bag. In the process, the connection ring 71 pulls the return spring 73 to be stretched and deformed, and after the push plate 74 is released, the pulling force of the return spring 73 and the air in the elevator tube 2 can push the stopper 65 to slide toward the release ring 62, and finally the elevator tube 2 is sealed through the matching of the sealing washer 66 and the sealing groove 67.
