Oblique openings are formed on one side of each of the two fixing blocks, and openings penetrating to the inside of the cage box are formed on the other side of each of the two fixing blocks.

[0009] Preferably, both of the openings are correspondingly opposite to the air outlet, and the inclined surfaces of the oblique openings are correspondingly attached to the bottom of the cover plate.

[0010] Preferably, the limiting and adjusting member includes a sliding block. The sliding block is slidably connected inside a sliding groove. A guiding groove penetrating to the inner side of the fixed frame is formed in the upper part near the front side inside the sliding groove. A plurality of limiting tooth grooves are equidistantly formed on the inner bottom surface of the guiding groove. The inner walls on one side of the plurality of limiting tooth grooves are all vertical, and the inner sides on the other side all extend obliquely upward in an arc shape. A protrusion is arranged on the inner top surface of the guiding groove near the open part of the fixed frame, and a protrusion is arranged on the inner bottom surface of the guiding groove near the other edge of the fixed frame.

[0011] Preferably, a fixing column is fixed near one edge of the front side of the sliding block. An installation opening is formed in the front side of the fixing column. A spring clip is clamped inside the installation opening. A double-headed connecting rod is rotatably connected to the middle part of the front side of the sliding block.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. During actual use, first connect one of the diversion pipes on the air supply support to the intake ends of the air purifier and the sterilizer, and then connect the other diversion pipe to the outlet ends of the air purifier and the sterilizer, so that the gas enters the interior of the breeding device through the diversion pipe, and then flows out from the interior of the breeding device and circulates in turn, thereby achieving the function of purifying and sterilizing the air. When installing the breeding device, the breeding device needs to be snapped onto the reset device, and then the breeding device is transported into the interior of the fixed frame through the limit adjustment member. When being transported into the interior of the fixed frame, the air outlet on the air supply support is docked through the breeding device, thus completing the conduction of the air flow;

[0017] 2. When the reset device works, first snap the limit block at the bottom of the cage box into the interior of the limit groove, and then make the bottom of the cage box fit with the top of the bent support plate, so as to support and slide the cage box. During the sliding, under the guidance of the guide rod and the docking block, the cage box can be transported into the interior of the fixed frame, and at the same time, the spring is compressed, so that when disassembling later, after unlocking the limit adjustment member, the cage box can be pushed outwards under the elastic force of the spring, which is convenient for people to replace;

[0018] 3. When the limit adjustment member works, during the process of the reset device transporting the cage box, the sliding block slides in the sliding groove, so that the limit wheel can be driven to slide successively in the limit tooth groove. The limit wheel is limited by the vertical surface on one side of the limit tooth groove, and when the limit wheel slides in multiple limit tooth grooves, it will drive the double-headed connecting rod to swing, so that one end of the spring card reciprocates in the arc-shaped notch. When the cage box is transported to one inner wall of the fixed frame, under the guidance of the inclined opening on the fixed block, the cover plate inside the air outlet is jacked upwards, so that the air outlet corresponds to the opening, and thus the air inside the diversion pipe can be introduced into the interior of the cage box from the opening. When unlocking the limit adjustment member, only need to press the cage box towards the inner side of the fixed frame again, so that the limit wheel slides to the protrusion near one edge at the bottom surface of the guide groove. Under the action of the protrusion, the limit wheel is jacked upwards, so as to drive the double-headed connecting rod to rotate, and thus one end of the spring card is snapped into the positioning groove, thereby fixing the double-headed connecting rod. Then, under the action of the reset device, the sliding block is pushed to the other side of the fixed frame. At this time, the limit wheel contacts the protrusion on the top surface of the guide groove, and under the action of the protrusion, the limit wheel is pressed downwards, so that one end of the spring card slides out of the positioning groove.
