A cabinet door 2 is rotatably connected to the outer wall of the steam sterilizer main body 1. The sterilization chamber 3 is arranged inside the steam sterilizer main body 1. The cabinet door 2 is used for opening and closing the sterilization chamber 3. Instruments are placed into the sterilization chamber 3 through a placement mechanism 4. The placement mechanism 4 includes a mounting plate 401. The mounting plate 401 is arranged on the inner wall of the sterilization chamber 3. A placement frame 402 is fixedly connected to the outer wall of the mounting plate 401. One end of the placement frame 402 is provided with a connecting plate 403. A connecting groove 404 is formed on the outer wall of the connecting plate 403. Two fixing blocks 405 are symmetrically and slidably connected inside the connecting plate 403. The fixing blocks 405 extend into the inner cavity of the connecting groove 404. A first spring 406 is connected between the fixing blocks 405 and the connecting plate 403. A rotating ring 407 is rotatably connected to the outer wall of the connecting plate 403. A round rod 408 is fixedly connected to the outer wall of the fixing block 405. An inclined groove 409 is formed on the outer wall of the rotating ring 407. The placement frame 402 is rotated through a rotating mechanism 5.

[0020] The placement mechanism 4 further includes a support plate 410. The support plate 410 is symmetrically and fixedly connected to both sides of the inner wall of the placement frame 402. Above the two support plates 410, there is a mounting rod 411. The mounting rod 411 is fixedly connected to the mounting plate 401. A tray 418 is slidably connected to the top end of the support plate 410. A sliding groove 412 is formed on the outer wall of the mounting rod 411. Two sliders 413 are symmetrically and slidably connected to the inner wall of the sliding groove 412. The bottom end of the slider 413 is rotatably connected to a connecting rod 414. The bottom end of the connecting rod 414 is rotatably connected to a pressing mesh plate 415. A threaded rod 416 passing through the slider 413 is rotatably connected inside the mounting rod 411. One end of the threaded rod 416 is fixedly connected to a rotating block 417. A groove 419 for the rotating block 417 to slide into is formed on the inner wall of the connecting groove 404.

[0021] In this embodiment: The number of the support plates 410, the mounting rods 411, the downward pressing mesh plates 415, and the trays 418 are correspondingly set to three groups. When placing the appliances, the appliances are placed layer by layer into each tray 418, and then the tray 418 is placed on the top of the support plate 410 in the placement frame 402. After completion, rotate the rotating block 417. The rotation of the rotating block 417 drives the threaded rod 416 to rotate. The rotation of the threaded rod 416 drives the two sliders 413 to displace in the chute 412 in the opposite direction. The displacement of the slider 413 drives the downward pressing mesh plate 415 to displace through the connecting rod 414. The downward pressing mesh plate 415 displaces into the tray 418 to press the appliance tightly in the tray 418. Then, insert the placement frame 402 into the connection groove 404, insert the rotating block 417 into the groove 419, and the fixed block 405 displaces under the elastic force of the first spring 406 and engages with one end of the placement frame 402, so as to fix between the connecting plate 403 and the placement frame 402. At this time, the mounting plate 401, the placement frame 402, and the connecting plate 403 can be placed into the sterilization chamber 3 together, and the appliance enters the sterilization chamber 3 along with the placement frame 402, facilitating the subsequent sterilization operation.

[0022] When removing the connecting plate 403, rotate the rotating ring 407. The rotation of the rotating ring 407 drives the round rod 408 to slide in the inclined groove 409. The displacement of the round rod 408 drives the fixed block 405 to displace, squeezing the first spring 406. The fixed block 405 displaces out of the connection groove 404, thus canceling the fixation of the connecting plate 403. At this time, the connecting plate 403 can be separated from the placement frame 402. Then, the appliance in the placement frame 402 can be taken out. Rotate the rotating block 417 to drive the downward pressing mesh plate 415 to reset, and then take out the tray 418 from the placement frame 402. At this time, the appliance can be taken out from the tray 418.
