In addition, the sticking fixation method is relatively cumbersome and inconvenient to operate.

[0004] Therefore, a mouse experiment fixation device is needed that can stably and conveniently fix the mouse body and tail to avoid damaging the mouse. Utility Model Content

[0025] Reference Figure 1 、 Figure 2 and Figure 5As shown, specifically, the restraint assembly 4 includes a restraint bucket 41, a positioning sleeve 42, a threaded tube 43, an extrusion nut 44, an inclined connecting plate 45 and an extrusion plate 46. The restraint bucket 41 is fixed to the middle of the adjustment frame 3. The restraint bucket 41 is bucket-shaped and can support and limit mice of different sizes. The bottom of the restraint bucket 41 is connected with a positioning sleeve 42. The positioning sleeve 42 has a certain size to allow the tail of a larger mouse to pass through. The outer side of the positioning sleeve 42 is sleeved with a threaded tube 43. The upper end of the threaded tube 43 is fixed to the outer wall of the lower end of the restraint bucket 41. The outer side of the upper end of the threaded tube 43 is threadedly connected to the extrusion nut 44. The outer wall of the lower end of the threaded tube 43 is fixedly connected to the inclined connecting plate 45; the bottom of the extrusion nut 44 is fixed with a top ring 441, the pushing ring 441 is located above the inclined connecting plate 45, and can be moved by screwing the squeezing nut 44 to squeeze the inclined connecting plate 45; a squeezing plate 46 is fixed to the bottom of the inclined connecting plate 45, and four of the inclined connecting plate 45 and the squeezing plate 46 are provided; when fixing a mouse, this solution can place the mouse into the inner side of the restraint bucket 41 so that the mouse's tail passes through the positioning sleeve 42 at the bottom of the restraint bucket 41, and then the squeezing nut 44 is screwed to push the inclined connecting plate 45 toward the positioning sleeve 42, so that multiple squeezing plates 46 can move inward to achieve a tight fixation of the mouse's tail, which can better fix the mouse's tail and facilitate experimental infusion operations. At the same time, it can be used for mice of different sizes and is highly practical.

[0026] Reference Figure 1 、 Figure 2 and Figure 4 As shown, specifically, the limiting bucket 5 is inserted into the inner side of the upper end of the restraining bucket 41; the outer wall of the limiting bucket 5 is fixed with a friction ring 51, which can increase the friction between the limiting bucket 5 and the restraining bucket 41, making the insertion more stable, and the top of the limiting bucket 5 is fixed with an operating ring 52 for hand-held operation by the experimenter; in this scheme, the mouse is placed in the inner side of the restraining bucket 41 through the setting of the limiting bucket 5 to limit and fix the mouse's tail, and then the limiting bucket 5 can be inserted and sleeved on the outside of the mouse's head, and the mouse's body can be fixed by squeezing, and the fixing operation is convenient and stable.

Then, the experimenter can rotate the squeezing nut 44 on the threaded tube 43 outside the positioning sleeve 42 to move the squeezing nut and push the inclined connecting plate 45 below, thereby driving the squeezing plates 46 around to squeeze inward, thereby squeezing and fixing the mouse's tail. Then, the experimenter inserts the limiting bucket 5 into the inner side of the upper end of the restraint bucket 41, and the limiting bucket 5 is sleeved on the outside of the mouse's head. At the same time, the mouse's body is fixed by squeezing, which is stable and easy to operate.
