[0059] The cabinet 200 has an operation opening 210 and a positioning groove 310 surrounding the operation opening 210;

[0060] The glass 300 is clamped in the positioning groove 310 by the fixing clamping plate 320 on the cabinet 200;

[0062] A plurality of elastic partition membranes 500 are respectively located in the cabinet 200;

[0063] The expansion and contraction structures 600 are respectively disposed in the cabinet 200 and are used to expand or contract the elastic partition membrane 500 in the cabinet 200. The expansion and contraction structures 600 are the first adjustment structure 610, the second adjustment structure 620 or the third adjustment structure 630;

[0064] When the elastic partition membrane 500 is stretched, the elastic partition membrane 500 divides the cabinet 200 into a plurality of independent operating spaces, and when the elastic partition membrane 500 is contracted, the internal space of the cabinet 200 is integrated.

[0065] This embodiment is implemented as follows:

[0066] When the present application is in use, the elastic partition membrane 500 in the operating room of the cabinet 200 can be unfolded through the first adjustment structure 610, the second adjustment structure 620 or the third adjustment structure 630 in the expansion and contraction structure 600, so that the elastic partition membrane 500 separates the operating room of the cabinet 200, facilitates the separation operation, and avoids mutual contamination.

[0067] See also Figure 2 , 3 , 4, 5, the first adjustment structure 610 includes

[0068] Two first moving grooves 612 are respectively disposed at corresponding positions of the upper end wall and the lower end wall in the operating room of the cabinet 200;

At this time, the first magnet 635 is separated from the second movable plate 634, and then the second movable plate 634 moves along the second movable groove 631 to the third hidden groove 633, thereby unfolding the third elastic strip 637 and the elastic partition membrane 500 to achieve the separation of the operating room of the cabinet 200.
