[0028] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 , a fixing bracket for mouse eye drug testing, including a fixed plate 1. The fixed plate 1 is provided with a binding mechanism for fixing the limbs of the mouse and a fixing mechanism for fixing the head of the mouse. Four sliding grooves 11 are opened on the fixed plate 1. A connecting slide bar 2 is slidably connected inside each sliding groove 11. The binding mechanism includes a connecting seat 3 rotating on the sliding groove 11. A binding strap 7 is installed on one side surface of each connecting seat 3. By controlling the sliding of the connecting slide bar 2 inside the sliding groove 11, the positions between the connecting seats 3 are adjusted, and the binding mechanism can be adjusted according to the mouse body type. The limbs of the mouse are fixed on one side surface of the connecting seat 3 through the binding strap 7. The bottom of the connecting slide bar 2 is fixedly connected with a connecting plate 21. The connecting plate 21 is connected to the bottom of the fixed plate 1 through a fixing bolt. Multiple groups of screw holes adapted to the fixing bolt are opened at the bottom of the fixed plate 1. By removing the fixing bolt on the connecting plate 21, the connecting slide bar 2 can freely slide inside the sliding groove 11, and then the position of the connecting seat 3 is fixed through the action of the fixing bolt and the screw holes. A binding strap is arranged in the middle part of the fixed plate 1 to bind and fix the body of the mouse.

[0029] Please refer to again Figure 1 , Figure 2 and Figure 5, a rotating cylinder 31 is rotatably connected inside the connecting seat 3. One end of the binding strap 7 is fixedly connected to one side surface of the connecting seat 3, and the other end of the binding strap 7 extends into the connecting seat 3 and is fixedly connected to the rotating cylinder 31. By rotating the rotating cylinder 31, one end of the binding strap 7 is wound up, so that the binding strap 7 fixes the limb of the mouse. A cross-shaped slide bar 32 is slidably connected inside the rotating cylinder 31, and an inner top wall of the connecting seat 3 is fixedly connected with a socket 33. A cross-shaped slot 34 adapted to the cross-shaped slide bar 32 is opened at the bottom of the socket 33. After binding, one end of the cross-shaped slide bar 32 is inserted into the inside of the cross-shaped slot 34 to limit the rotation of the rotating cylinder 31, thereby completing the fixation of one end of the binding strap 7. By pulling one end of the cross-shaped slide bar 32 out of the inside of the cross-shaped slot 34, the rotating cylinder 31 can rotate freely.

[0030] Please refer to again Figure 1 , Figure 3 and Figure 4 , the fixing mechanism includes a movable seat 4 installed on the fixing plate 1. The top of the movable seat 4 is hinged with a movable pressing rod 5 through a pin shaft. One end of the movable pressing rod 5 is hinged with an arc-shaped pressing plate 6 through a pin shaft. By pulling the other end of the movable pressing rod 5 to rise, one end of the movable pressing rod 5 descends, so that the head of the mouse is fixed by the arc-shaped pressing plate 6, preventing the head of the mouse from shaking and affecting the experimenter from administering medicine to the eyes of the mouse. A through groove 51 is opened at the other end of the movable pressing rod 5. One side surface of the movable seat 4 is fixedly connected with a mounting plate 41. An adjusting bolt 42 is threadedly connected to the mounting plate 41. The adjusting bolt 42 is arranged inside the through groove 51. A fixing bead 43 is fixedly connected to the adjusting bolt 42. The fixing bead 43 is arranged directly below the through groove 51. The diameter value of the fixing bead 43 is greater than the width value of the through groove 51. By rotating the adjusting bolt 42, the fixing bead 43 is driven to rise, and the fixing bead 43 pushes one end of the movable pressing rod 5 to turn upwards.

[0031] Please refer to again Figure 1 , Figure 3 and Figure 4 , a chute 12 is opened at the top of the fixing plate 1. An adjusting screw 13 is rotatably connected inside the chute 12. The bottom of the movable seat 4 is slidably connected inside the chute 12. The bottom of the movable seat 4 is threadedly connected to the adjusting screw 13. By rotating the adjusting screw 13, the movable seat 4 can be quickly adjusted on the top of the fixing plate 1, so that the fixing mechanism quickly approaches the head of the mouse.

[0032] Please refer to again Figure 1 and Figure 6, four support columns 8 are installed at the bottom of the fixing plate 1, and the four support columns 8 are distributed at the four corners of the bottom of the fixing plate 1. The bottom of the fixing plate 1 is supported by the plurality of support columns 8 provided. The support column 8 is a telescopic rod with a positioning mechanism. The telescopic end of the support column 8 is hinged to the bottom of the fixing plate 1 through a pin shaft. By adjusting the length values of the two groups of support columns 8, the overall inclination direction of the fixing plate 1 is adjusted to facilitate various examinations and experiments on the eyes of mice.

[0033] Working principle: Place the mouse on the top of the fixing plate 1. The four limbs of the mouse respectively extend into the interiors of the four binding straps 7. By rotating the rotating cylinder 31, the binding straps 7 are wound up so that the binding straps 7 bind the limbs of the mouse to the side of the connecting seat 3. Then, one end of the cross slide bar 32 is inserted into the interior of the cross slot 34 to limit the rotation of the rotating cylinder 31. Then, by rotating the adjusting screw 13, the movable seat 4 is moved closer to the head of the mouse. By rotating the adjusting bolt 42, the fixing bead 43 is driven to rise. The fixing bead 43 pushes one end of the movable pressure bar 5 to flip upward, so that the other end of the movable pressure bar 5 flips downward. The head of the mouse is fixed by the arc-shaped pressing plate 6 to prevent the head of the mouse from shaking and affecting the experimenter to administer medicine to the eyes of the mouse. By removing the fixing bolt at the bottom of the connecting plate 21, the connecting slide bar 2 slides in the sliding slot 11 to adjust the distance value between the connecting seats 3, and the positions of the connecting seats 3 can be adjusted according to the body size of the mouse.
