[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0025] Example 1

[0026] Reference Figure 1 , a blood supply and anti-loosening device for mice, which is used in the field of biomedical equipment, includes: a shell 1, a fixing frame and a fixing assembly. The shell 1 serves as a protective shell for the entire device, and is used to accommodate and fix other components. The fixing frame is arranged inside the shell 1, and is used to fix the mice to ensure that they do not move or escape during the blood supply process. The fixing frame specifically includes a mesh frame 2 and two fixing plates 3 respectively arranged on both sides of the mesh frame 2. The design of the mesh frame 2 allows blood supply operation while ensuring the breathing and comfort of the mice.

[0027] Example 2

[0028] refer to Figure 2, based on the improvement of Example 1: the fixing assembly is used to fix the housing 1 and the fixing plate 3 to ensure the stability of the entire device. The fixing assembly is arranged inside the fixing plate 3, and includes multiple sliding cavities 9 opened inside the fixing plate 3. An insertion rod 10 is slidingly arranged inside the sliding cavity 9. Multiple rows of sockets 11 are opened on both sides of the housing 1, and each row of sockets 11 is provided with multiple cavities. When the housing 1 needs to be fixed, the insertion rod 10 is slid through the multiple sockets 11 in the same row on the same side to achieve a firm connection between the housing 1 and the fixing plate 3.

[0029] Furthermore, one end of the insertion rod 10 is fixedly mounted to the side plate 8, and a compression spring 12 is sleeved around the outer wall of the insertion rod 10. The ends of the compression spring 12 are respectively fixed to one inner wall of the sliding cavity 9 and one side of the side plate 8. The provision of the compression spring 12 enables the insertion rod 10 to automatically return to the interior of the sliding cavity 9 when no external force is applied, facilitating subsequent disassembly and reuse.

[0030] In order to more conveniently control the extension and retraction of the insertion rod 10, the fixing assembly also includes an L-shaped slide 6. An L-shaped slide 4 is provided on one side of the fixing plate 3, and the L-shaped slide 6 is slidably arranged inside the L-shaped slide 4. The L-shaped slide 4 is connected to a plurality of slide cavities 9 on the same side, so that the L-shaped slide 6 can push or pull the insertion rod 10 during the sliding process. An inclined surface 7 is provided on the inner wall of one side of the L-shaped slide 6, and the inclined surface 7 cooperates with a plurality of side panels 8 on the same side. When the L-shaped slide 6 slides inside the L-shaped slide 4, the inclined surface 7 will push or pull the side panel 8, thereby driving the insertion rod 10 to extend or retract.

[0031] To maintain the stability of the L-shaped slide 6, a limit rod 17 is fixedly mounted inside the L-shaped chute 4. The L-shaped slide 6 slides over the outer wall of the limit rod 17. Furthermore, a tension spring 5 is mounted on the outer wall of the limit rod 17. The ends of the tension spring 5 are respectively fixed to the top inner wall of the L-shaped chute 4 and the top of the L-shaped slide 6. The tension spring 5 ensures that the L-shaped slide 6 automatically returns to its initial position when no external force is applied.

[0032] Reference Figure 3-4 In addition, the fixing assembly also includes a fixing rod 16. A transverse sliding groove 13 is provided on one side of the L-shaped slide 6, and a slider 14 is slidably provided inside the transverse sliding groove 13. One end of the slider 14 is fixed to the fixing rod 16, and the other end of the slider 14 extends to the outside of the transverse sliding groove 13. A fixing groove 15 is provided on the inner wall of one side of the L-shaped slide 4. When the L-shaped slide 6 slides to the appropriate position, the fixing rod 16 is slid through the inside of the fixing groove 15 to fix the L-shaped slide 6. This design allows the L-shaped slide 6 to remain stable and motionless when needed, further improving the stability of the entire device.

[0033] When the jack is in the upright position, the jack 1 is moved to the left and right positions, and the jack 1 is moved to the right and left positions, and the jack 1 is moved to the right and left positions, and the jack 1 is moved to the left and right positions, and the jack 1 is moved to the right and left positions, and the jack 1 is moved to the right and left positions, and the jack 1 is moved to the right and left positions, and the jack 1 is moved to the right and left positions, and the jack 1 is moved to the right and left positions, and the jack 1 is moved to the right and left positions, and the jack 1 is moved to the right and left positions, and the jack 1 is moved to the right and left positions,

[0034] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
