[0020] like Figure 2 and 3 As shown, a driving cavity 7 is arranged on the rear side wall of the cabinet 1, and a driving motor 8 is arranged under the inner top wall of the driving cavity 7. The output end of the driving motor 8 is connected with a threaded rod 9, and the bottom end of the threaded rod 9 is rotatably arranged on the inner bottom wall of the driving cavity 7. A threaded collar 10 is threadedly sleeved on the threaded rod 9, and the side end of the threaded collar 10 moves through the side walls of the driving bin and the working bin 3 to be connected to the operating table 5. The driving motor 8 drives the threaded rod 9 to rotate, and the threaded collar 10 converts the rotary motion of the threaded rod 9 into a linear reciprocating motion, and the threaded collar 10 drives the operating table 5 to slide in the slide groove 4, so that the lifting and lowering movement of the operating table 5 adjusts the volume of the working bin 3 that needs to be ventilated.
