[0002] In recent years, the safety issues of biological laboratories have received attention. Biological experiments refer to the process of observing the structure and life activities of organisms under specific environmental conditions. Waste from microbiological laboratories is mostly infectious waste, and waste is divided into liquid waste and solid waste. Commonly used sterilization methods are high pressure and incineration. An autoclave is a high-pressure container that uses a pressure higher than normal pressure to raise the boiling point of water to a high temperature of more than 100°C to sterilize liquids or instruments.

[0003] For example, the "A High-Pressure Sterilizer" with publication number CN218979857U includes a sterilization box, an exhaust assembly and a sterilization cylinder. A heating element is installed at the bottom of the sterilization box, and a limiting element for limiting the sterilization cylinder in the sterilization box is installed in the sterilization box. A plurality of through holes are opened on the side wall of the sterilization cylinder, and the plurality of through holes are arranged along the circumference of the sterilization cylinder. A gap is left between the outer wall of the sterilization cylinder and the sterilization box; a connecting rod and a plurality of trays are installed in the sterilization cylinder, and the connecting rod is detachably connected to the tray, and the plurality of trays are arranged at intervals along the axial direction of the connecting rod, and a plurality of trays are arranged in multiple layers in the sterilization cylinder. When sterilizing, the objects to be sterilized are first placed on the plurality of trays in turn, so as to reduce contact and crowding between the objects to be sterilized, and the plurality of objects to be sterilized are arranged in multiple layers so as not to cause stacking; the sterilization effect of the objects to be sterilized is improved.

[0004] Although the above-mentioned sterilizer fixture has certain advantages in improving the sterilization effect, it still has certain disadvantages:
