[0001] The utility model relates to the field of experimental mouse fixation, and particularly relates to an experimental mouse fixator. Background Art

[0002] Chinese patent document CN 212346801 U discloses one which includes a barrel cover. The relative distance between two hoop rings is adjusted by a connecting column to adapt to the length of the experimental mouse. The front and rear hoop rings respectively bind the armpit and groin parts of the experimental mouse, so that the experimental mouse is suspended on a suspension plate, ensuring that the abdomen of the experimental mouse faces downwards. The two barrel covers are closed, and the narrow space of the barrel cover 3 limits the limbs of the experimental mouse. When the experimental mouse is in the narrow space, due to the instinct of the animal, the experimental mouse will be in a calm state.

[0003] However, the device has the following problems. The relative distance between the two hoop rings can only be adjusted by a lock nut, with low adjustment efficiency and inconvenience. At the same time, when the barrel cover is closed to form a closed space for the experimental mouse, if it is closed too tightly, it is easy to squeeze the experimental mouse, and if it is closed too wide, the experimental mouse will move around, which is not conducive to the operation of the staff. Summary of the Utility Model

[0004] The purpose of the utility model is to provide an experimental mouse fixator to solve the technical problem of inconvenient operation of the adjustment fixing device mentioned above.

[0005] To solve the above technical problem, the utility model provides an experimental mouse fixator, which includes a workbench and a lead screw device. The lead screw device is arranged on the side of the workbench. Two bidirectional support devices are arranged on the lead screw device. The support device includes a support frame and a support rod. The function of the support frame is to support an elastic band. The support frame is connected to the support rod through a cross bar, and the cross bar is movably connected to the support rod. First through hole and a second through hole are longitudinally arranged at intervals on the workbench. A first rough surface is arranged on the back of the workbench on the side of the first through hole. A third through hole is arranged on one side of the workbench away from the lead screw device, and a second rough surface is arranged on the side of the third through hole. The elastic band is provided with corresponding hook surfaces corresponding to the first rough surface and the second rough surface.

[0006] Further, the front end of the lead screw device is connected to a dial, and anti-slip lines are arranged at the upper and lower ends of the dial.

[0007] Further, two sliders are arranged on the lead screw device, and the support rod is connected to the lead screw device through the sliders.

[0008] Further, a sponge pad is arranged on the workbench between the first through hole and the second through hole.

[0009] Further, a hinge is provided at the connection between the support rod and the cross bar, and the cross bar and the support rod are movably connected through the hinge.

[0010] Further, a connecting rod is provided between the two cross bars. A first L-shaped plate is provided at the upper end of the connecting rod, and a second L-shaped plate is provided at the lower end of the connecting rod.

[0011] Further, a partition is provided between the lead screw device and the workbench.

[0012] Further, a cylinder cover is provided at the rear end of the sponge pad on the workbench.

[0013] The beneficial effects of the present utility model are as follows: Compared with the prior art, for an experimental mouse fixator, elastic bands corresponding to experimental mice of different body types are selected. One end of the elastic band is fixed by fitting the hook surface with the first hair surface on the back of the first through hole. Then, the other end of the elastic band passes through the first through hole from bottom to top, turns downwards through the second through hole, and then passes through the third through hole. After the staff lifts the elastic band, the lead screw device is rotated to adjust the two support devices to approach each other until the support frames on the support devices lift the elastic band. Then, the experimental mouse is placed into the elastic band. The lead screw device is rotated in the reverse direction to adjust the two support devices to move away from each other. After the elastic band fixes the experimental mouse, the hook surface on the elastic band is fixed by fitting it with the second hair surface, which is convenient for the staff to operate. Fixing the experimental mouse reduces the stress response of the experimental mouse and is suitable for fixing experimental mice of different body types. BRIEF DESCRIPTION OF THE DRAWINGS
