the laboratory mouse can run on the roller 208, so that the roller 208 is driven to rotate in the observation box 1 through the shaft rod 210, the shaft rod 210 is connected with the pull rope 205, the shaft rod 210 is wound on the pull rope 205, the other end of the pull rope 205 is fixedly connected with the grid plate 202, so that the grid plate 202 is pulled to move upwards along the central axis direction of the sliding groove 203 of the partition plate 201, the grid plate 202 is stretched to a certain height, at the moment, the laboratory mouse can enter the diet cabin 4 from the rest cabin 3 through a gap between the partition plates 201, and meanwhile, the roller 208 drives the generator 212 to rotate through the matching of the shaft rod 210 and the gear box 211, so that electric energy is generated to supply the operation of the illuminating lamp 7 and the camera 8;

secondly, a laboratory mouse can step on one end of the pedal 502, at the moment, the pedal 502 rotates along the positioning pin 503 and pulls the pull rod 504, the pedal 502 is indirectly connected with the adjusting rack 510 through the matching of the pull rod 504 and the connecting rod 505, so that the adjusting rack 510 is pulled to move downwards, the adjusting rack 510 is meshed with the half-tooth gear 509, the half-tooth gear 509 is pulled to drive the shielding plate 507 to rotate through the connecting shaft rod 508, a certain angle is formed between the shielding plate 507 and the fixing plate 506, materials flow out from the storage bin 515, the adjusting rack 510 is pushed to return to the initial state under the action of the return spring 511, and the materials can be continuously obtained through stepping on the pedal 502;

then, the material is not enough in the storage bin 515, the material can be guided into the storage bin 515 through the feeding port 514, at the moment, the push plate 513 is adjusted to be in a vertical state through the matching of the limiting spring and the positioning pin, and the feeding port 514 is closed

Finally, if the laboratory mouse returns to the rest compartment 3, it turns on the roller 208 on the other side of the partition 201 and winds the pulling rope 205 through the shaft 210 of the roller 208 and pulls the grid plate 202 up into the rest compartment 3.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be able to cover the technical scope of the present invention and the equivalent alternatives or modifications according to the technical solution and the inventive concept of the present invention within the technical scope of the present invention.
