Operating the adjusting knob 407 to rotate can drive the first connecting rod 408 to rotate, and when the first connecting rod 408 rotates, it drives the second connecting rod 409 to move and makes the second guide column 406 slide along the straight slot 403 first under the push of the second connecting rod 409, so that the inner cabinet door 300 moves away from the inner cabinet body 200 in the horizontal direction under the drive of the movable bracket 402. When the first guide column 405 abuts the end of the straight slot 403 and the adjusting knob 407 continues to rotate, the second guide column 406 enters the circular arc slot 404 under the push of the second connecting rod 409 and moves within the circular arc slot 404. At this time, the movable bracket 402 rotates around the axis of the first guide column 405 and drives the inner cabinet door 300 to rotate, thereby opening the inner cabinet body 200.

[0033] Specifically, the adjusting knob 407 includes a connected head 410 and a rod 411. The rod 411 extends into the interior space of the inner cabinet 200 and the first connecting rod 408 is fixedly connected to the rod 411. The head 410 is located at the bottom of the inner cabinet 200 and between the inner cabinet 200 and the outer cabinet 100. The head 410 of the adjusting knob 407 is arranged outside the inner cabinet 200 and between the inner cabinet 200 and the outer cabinet 100. When the inner cabinet 200 needs to be opened, the operator can insert his hand into the area between the bottom of the inner cabinet 200 and the inner wall of the outer cabinet 100 to operate the head 410 to rotate the adjusting knob 407. This facilitates the operation of the adjusting knob 407 to control the movement of the inner cabinet door 300 while preventing the adjusting knob 407 from being exposed, thereby preventing other people from opening the inner cabinet 200 at will.
