A through hole 3 is provided in the center of the cap 2, through which the mouse's tail can pass. A fixing mechanism 4 is provided at the top of the restraint sleeve body 1. The bottom of the fixing mechanism 4 is located inside the restraint sleeve body 1, and a clamp is provided at the bottom of the fixing mechanism 4 to fix the mouse. The clamp at the bottom of the fixing mechanism 4 can be adjusted by screwing on the top of the fixing mechanism 4. A support plate 5 is provided at the bottom of the restraint sleeve body 1. A strong light 6 is provided at the top left end of the support plate 5. The top of the support plate 5 is fixedly connected to the support plate 5. The strong light 6 is located on the left side of the restraint sleeve body 1. The bottom of the support plate 5 is provided with a sliding rod 7. The top of the sliding rod 7 is fixedly connected to the bottom of the support plate 5. A cylinder 8 is provided below the sliding rod 7. The sliding rod 7 can slide up and down inside the cylinder 8. A screw 9 is screwed on the side of the cylinder 8. By screwing the screw 9 inward, the screw 9 can be made to abut against the side of the sliding rod 7, thereby fixing the sliding rod 7 and preventing it from moving up and down. A base 10 is provided at the bottom of the cylinder 8. The top of the base 10 is fixedly connected to the bottom of the cylinder 8. An auxiliary component is provided on the support plate 5. The auxiliary component is used to assist the needle tip in piercing the blood vessel, avoid blind injection by feel, and improve the injection success rate. The auxiliary component includes a fixing block 11 and a magnifying glass 18. When using it, first place the mouse into the restraint sleeve body 1, then fix the mouse by screwing the top of the fixing mechanism 4, then pass the mouse's tail through the through hole 3 on the cover 2, then screw the cover 2 onto the left end of the restraint sleeve body 1, place the mouse's tail above the strong light lamp 6, and the veins on the mouse's tail can be clearly seen through the light transmission. When the height needs to be adjusted, the screw 9 can be unscrewed, and then the height of the slide bar 7 can be adjusted up and down. After adjustment, screw 9 can be screwed inward to tighten it.

[0025] like Figure 1 and Figure 2 As shown, the front of the high-intensity light 6 is provided with a fixing block 11, the bottom of the fixing block 11 is fixedly connected to the top of the support plate 5, the interior of the fixing block 11 is provided with a cavity 12, and the front of the fixing block 11 is provided with an opening. Figure 2 As shown, a damping ring 13 is provided inside the cavity 12. The outer side of the damping ring 13 is fixedly connected to the inner side wall of the cavity 12. A damping disk 14 is provided inside the damping ring 13. The damping disk 14 can rotate inside the damping ring 13, but it will be subject to frictional resistance when rotating inside the damping ring 13. A certain force is required for the damping disk 14 to rotate inside the damping ring 13. A connecting rod 15 is provided on the front side of the damping disk 14. The connecting rod 15 is fixedly connected to the front side of the damping disk 14. The connecting rod 15 can pass through the opening on the front side of the fixing block 11. Figure 1 and Figure 2As shown, an adjustment disc 16 is located on the outer end of the connecting rod 15, which is fixedly connected to the outer end of the connecting rod 15. A long rod 17 is located on the top of the adjustment disc 16, and the bottom of the long rod 17 is fixedly connected to the top of the adjustment disc 16. A magnifying glass 18 is located on the side of the top of the long rod 17, which is positioned above the strong light lamp 6. The weight of the magnifying glass 18 and the long rod 17 prevents the damping disc 14 from rotating within the damping ring 13. Therefore, the angle of the magnifying glass 18 is fixed under normal conditions. When the angle needs to be adjusted, the adjustment disc 16 can be manually rotated to overcome the frictional resistance between the damping disc 14 and the damping ring 13, allowing the angle of the magnifying glass 18 to be adjusted by rotating the adjustment disc 16. This design allows the magnifying glass 18 to assist the needle tip in piercing the blood vessel, avoiding blind injection by feel and improving the success rate of injection.

[0026] like Figure 1 and Figure 3 As shown, the base 10 has multiple connecting blocks 19 on both its front and back sides. These connecting blocks 19 are fixedly connected to the base 10, and the bottom surface of each connecting block 19 is recessed inward to form a groove 20. Figure 3 As shown, the top surface of the connecting block 19 is provided with a threaded hole 21, the bottom of the threaded hole 21 is connected to the top of the groove 20, a cylinder 22 is provided inside the threaded hole 21, and the side of the cylinder 22 is provided with an external thread 23. The cylinder 22 is screwed into the threaded hole 21 through the external thread 23. Figure 3 As shown, the top of the cylinder 22 is provided with a screw cap 24, which is located above the connecting block 19. The bottom of the screw cap 24 is fixedly connected to the top of the cylinder 22. By rotating the screw cap 24, the cylinder 22 can be moved up and down within the connecting block 19. The bottom end of the cylinder 22 is provided with a hollow cavity 25, and the bottom surface of the cylinder 22 is provided with an opening. Figure 3 As shown, a limiting plate 26 is provided inside the hollow cavity 25. The limiting plate 26 can only rotate within the hollow cavity 25. A fixing rod 27 is provided at the bottom of the limiting plate 26. The top end of the fixing rod 27 is fixedly connected to the bottom end of the limiting plate 26. The bottom end of the fixing rod 27 passes through the opening on the bottom surface of the cylinder 22. A suction cup 28 is provided at the bottom end of the fixing rod 27. The top end of the suction cup 28 is fixedly connected to the bottom end of the fixing rod 27. In use, by twisting the screw cap 24 downwards, the cylinder 22 moves the suction cup 28 downwards, eventually causing the suction cup 28 to be pressed and adhered to the plane for fixation. By sequentially adhering the suction cups 28 in the four connecting blocks 19 to the plane, the base 10 can be fixed to the plane and cannot move. When it is necessary to move the base 10, simply rotate the screw cap 24 upwards, and the suction cup 28 will detach from the plane. This setting can firmly fix the base 10 to the plane, avoiding displacement of the base 10 during injection and preventing injection failure, thus enhancing stability.
