[0035] Please refer to Figures 2-4 In order to fix the limbs of the experimental mouse, one of the fixing assemblies 3 comprises at least two fixing structures, the fixing structure comprises a mounting plate 301, a mounting seat 302, a connecting shaft 303, a clamping plate 304 and a connecting piece, the mounting plate 301 is attached to the placing plate 1, the mounting seat 302 is rotatably connected to the mounting plate 301, the connecting shaft 303 is arranged in the mounting seat 302, the clamping plate 304 is rotatably connected to the outer side of the connecting shaft 303, and the side of the clamping plate 304 away from the connecting shaft 303 is connected to the mounting plate 301 through the connecting piece.

[0036] In actual use, the two joint parts of the limbs of the experimental mouse are respectively placed on the two fixing structures and attached to the mounting plate 301 of the fixing structure, the clamping plate 304 is attached to the outer side of the joint by rotating the clamping plate 304, and the side of the clamping plate 304 is connected to the mounting plate 301 through the connecting piece, so as to fix the two joint parts of the limbs of the experimental mouse.

[0037] In actual setting, the position of the clamping plate 304 can be flexibly adjusted by rotating the clamping plate 304 rotatably connected to the mounting seat 302, so that the clamping plate 304 can be closely attached to the joints of different sizes and positions of the experimental mouse, and the fixing accuracy and stability are improved, the design of the clamping plate 304 structure allows the joint parts of the limbs of the experimental mouse to be firmly clamped, and the use of the connecting piece further enhances the reliability of the fixing, so as to ensure that the limbs of the experimental mouse do not move randomly during the experiment.

[0038] Further, in order to ensure the stability of the clamping plate 304 in fixing the limbs of the experimental mouse, the clamping plate 304 is an elastic steel sheet, and at least two protrusions 305 are arranged on the lower surface of the clamping plate 304 along the extension direction of the clamping plate 304.

[0039] In actual settings, the elastic steel sheet has good elasticity and recovery, can closely fit the contour of the limbs of the experimental mouse, and at the same time, can provide sufficient clamping force, so as to ensure that the limbs will not be loosened or displaced due to external force or movement in the experiment, the design of the convex strips 305 increases the contact area and friction between the clamping plate 304 and the limbs of the experimental mouse, further enhances the stability of the fixation, and the convex strips 305 can also play a role in preventing slipping to prevent the experimental mouse from slipping when struggling.

[0040] Further, in order to adapt to the inner side of the limbs of the mouse, the upper end cross section of the middle four clamping plates 304 in the embodiment is arc-shaped, the middle four clamping plates 304 are respectively fitted to the inner side of the limbs of the mouse, and the arc-shaped parts of the middle four clamping plates 304 are curved towards the body position of the mouse, so as to better adapt to the shape of the inner side of the limbs of the mouse and improve the stability of the fixed limbs of the mouse.

[0041] In detail, in order to ensure the stable connection of the clamping plate 304 and the mounting plate 301 and facilitate the separation of the two, the connecting piece in the embodiment includes a vertical plate 306 vertically mounted on the upper surface of the mounting plate 301 and a connecting buckle 307 assembled on the side of the vertical plate 306 close to the clamping plate 304; corresponding to the connecting buckle 307, an arc-shaped block 308 is arranged on the right side of the clamping plate 304 close to the vertical plate 306.

[0042] It should be noted that the connecting buckle 307 is in the shape of a U-shaped, and part of the arc-shaped block 308 extends into the inside of the connecting buckle 307.

[0043] In actual use, when the clamping plate 304 is fitted to the limbs of the experimental mouse, one end of the clamping plate 304 is continuously pressed down, and the other end of the clamping plate 304 close to the vertical plate 306 is rotated towards the vertical plate 306, so that the arc-shaped block 308 moves below the connecting buckle 307; when the clamping plate 304 is released, the end of the clamping plate 304 away from the connecting shaft 303 will automatically rebound, thereby pushing the arc-shaped block 308 into the inside of the connecting buckle 307, and at the same time, the position of the clamping plate 304 is fixed.

[0044] Further, in order to be suitable for the limbs of experimental mice of different sizes, four groups of sliding grooves 309 are formed on the upper surface of the placement plate 1 in the embodiment, and the number of sliding grooves 309 in each group is two; a sliding block 310 is slidably connected in the sliding groove 309, the sliding block 310 is fixedly connected with the mounting plate 301, so that the mounting plate 301 can move left and right along the extension direction of the sliding groove 309, and a fastener 311 is threadedly connected in the mounting plate 301, and the bottom end of the fastener 311 abuts against the upper surface of the placement plate 1.

[0045] In actual use, the clamping plate 304 is moved to the optimal fixed position by moving the mounting plate 301, and in the process of moving, the sliding block 310 moves along the opening direction of the sliding groove 309, and the fastener 311 is tightened to make the bottom end of the fastener 311 abut against the upper surface of the placement plate 1, thereby completing the fixation of the mounting plate 301.

[0046] In actual setting, the sliding of the sliding block 310 in the sliding groove 309 enables the mounting plate 301 to move left and right along the extension direction of the sliding groove 309, thereby adjusting the position of the clamping plate 304 to accurately align and fix the limbs of experimental mice of different sizes. When the mounting plate 301 is moved to the desired position, the fastener 311 is tightened to make the bottom end thereof abut against the upper surface of the placement plate 1, thereby effectively fixing the mounting plate 301 and ensuring that the clamping plate 304 does not move or loosen during the experiment, improving the stability of the fixation.

[0047] Please refer to Figure 5 , in order to prevent the head of the experimental mouse from twisting during the dissection, a head limiting assembly 4 is arranged on the back side of the placement plate 1 corresponding to the arc-shaped groove 2;

[0048] The head limiting assembly 4 comprises limiting plates 401 arranged on the upper surface of the placement plate 1 and respectively located on the left and right sides of the arc-shaped groove, and a protective cover 402 slidably connected inside the two limiting plates 401. The left and right sides of the protective cover 402 are respectively formed with an extension edge 403 extending backward.

[0049] Corresponding to the extension edge 403, at least one fastening bolt 404 is threadedly connected to the top of the limiting plate 401, and the bottom end of the fastening bolt 404 abuts against the extension edge 403.

[0050] In actual use, the position of the protective cover 402 is adjusted according to the size of the experimental mouse, that is, the protective cover 402 is moved inside the limiting plate 401 to adjust the position of the protective cover 402 on the placement plate 1 to adapt to experimental mice of different sizes. Moreover, the position of the protective cover 402 is stably fixed by abutting the extension edge 403 against the limiting plate 401 by the fastening bolt 404, which prevents the protective cover 402 from moving or shaking during the dissection, and this stable fixation helps to further prevent the head of the experimental mouse from twisting and ensures the smooth progress of the dissection.

[0051] In actual setting, the operation of adjusting the position of the protective cover 402 is simple and easy to operate, that is, the protective cover 402 is moved inside the limiting plate 401 and fixed by the fastening bolt 404, so that the experimenter can quickly adjust the head limiting assembly 4 to adapt to experimental mice of different sizes, improving the experimental efficiency.

[0052] In addition, in order to ensure that the experimental mouse can normally breathe the air in the environment during the process of limiting, the protective cover 402 in the embodiment is protruded upwards away from the side of the placement plate 1 to form a protruding part, and a plurality of exhaust holes are arranged on the inner wall of the protruding part.

[0053] Although the embodiments of the present application have been shown and described, it should be understood by those ordinary skilled in the art that various changes, modifications, replacements and variations can be made to the embodiments without departing from the principles and spirits of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
