The lifting frame 3 is connected to the side of the filling pipe 2 away from the supporting frame 1. The motor 4 is connected to the lifting frame 3. The lifting frame 3 can move up and down.

[0022] When the liquid needs to be filled into the container, first of all, the container is moved to the placing opening 12, so that the container opening is directly below the guide opening 11, then the filling pipe 2 is connected with the conveying pipe conveying the liquid to be filled at one end away from the guide opening 11, the lifting frame 3 is started, so that the lifting frame 3 moves downward, the lifting frame 3 drives the filling pipe 2 to move downward, so that the filling pipe 2 extends into the container along the guide opening 11, then the conveying pipe is opened, so that the liquid to be filled enters the container through the filling pipe 2, at this time, since one end of the filling pipe 2 extends into the container, when the liquid is filled, even if the liquid spills, it will only spill into the container, and will not spill onto other structures, avoiding the waste of resources, and preventing the leakage of dangerous liquids such as acid liquid during filling. And through the guide opening 11, the filling pipe 2 can move along a fixed track when moving, so that the filling pipe 2 can accurately extend into the container, ensuring the accuracy during filling.

[0023] The connecting frame 5 comprises a connecting structure 51 and a connecting cylinder 52. The connecting structure 51 is connected with the motor 4.
