The lifting frame 32 is a U-shaped plate structure with a downward opening, and is fixedly connected with the inner wall of the top end of the separation box 30 through a telescopic rod. The lifting frame 32 is provided with internal threads that mate with the second threaded section 4703. When the driving motor 31 is operated, the driving shaft 47 is driven to rotate, and the lifting frame 32 can be lifted along the driving shaft 47. When the telescopic rod extends to the limit position, the lifting frame 32 is separated from the second thread section 4703 and enters the smooth section 4702, and due to the limit of the telescopic rod, when the driving motor 31 continues to rotate, the lifting frame 32 can not lift any more.

The side walls of the hollow plate 34 are in sliding contact with the inner wall of the lifting frame 32. The hollow plate 34 is provided with internal threads that mate with the first threaded segments 4701. When the telescopic rod is shortened to the limit position, the hollow plate 34 is disengaged from the first threaded section 4701 and enters the smooth section 4702, and at this time, the hollow plate 34 is not lifted at all times under the condition that the connecting spring 49 provides a pulling force to the hollow plate 34 toward the top of the separation box 30.
