The placement mechanism 4 includes a mounting plate 401. The mounting plate 401 is arranged on the inner wall of the sterilization chamber 3. The outer wall of the mounting plate 401 is fixedly connected to a placement frame 402. One end of the placement frame 402 is provided with a connection Plate 403, the outer wall of the connecting plate 403 is provided with a connecting groove 404, the interior of the connecting plate 403 is symmetrically and slidingly connected with a fixed block 405, the fixed block 405 extends to the inner cavity of the connecting groove 404, a first spring 406 is connected between the fixed block 405 and the connecting plate 403, the outer wall of the connecting plate 403 is rotatably connected to a rotating ring 407, the outer wall of the fixed block 405 is fixedly connected to a round rod 408, the outer wall of the rotating ring 407 is provided with an oblique groove 409, and the placement frame 402 is rotated by the rotating mechanism 5.

[0029] The placement mechanism 4 also includes a support plate 410, which is symmetrically fixedly connected to the two sides of the inner wall of the placement frame 402. A mounting rod 411 is provided above the two support plates 410, and the mounting rod 411 is fixedly connected to the mounting plate 401. The top of the support plate 410 is slidably connected to the tray 418, and the outer wall of the mounting rod 411 is provided with a slide groove 412. The inner wall of the slide groove 412 is symmetrically slidably connected with a slider 413. The bottom end of the slider 413 is rotatably connected to the connecting rod 414, and the bottom end of the connecting rod 414 is rotatably connected to the pressing mesh plate 415. The inside of the mounting rod 411 is rotatably connected to a threaded rod 416 that passes through the slider 413, and one end of the threaded rod 416 is fixedly connected to a rotating block 417. The inner wall of the connecting groove 404 is provided with a groove 419 for the rotating block 417 to slide into.

[0030] In this embodiment, there are three sets of support plates 410, mounting rods 411, pressing screens 415, and trays 418. When placing the equipment, the equipment is placed layer by layer into each tray 418, and then the tray 418 is placed into the placement frame 402 at the top of the support plate 410. After the placement is completed, the rotating block 417 is rotated, and the rotating block 417 rotates and drives the threaded rod 416 to rotate. The threaded rod 416 rotates and drives the two sliders 413 to move in opposite directions in the slide groove 412. The displacement of the slider 413 drives the pressing screen 415 to move through the connecting rod 414, and the pressing screen 415 moves into the tray 418. Press the instrument tightly into the tray 418, then insert the placement frame 402 into the connecting groove 404, insert the rotating block 417 into the groove 419, and the fixing block 405 is displaced by the elastic force of the first spring 406 and engages with one end of the placement frame 402, so that the connecting plate 403 and the placement frame 402 are fixed.
