[0032] The present invention will be further described below in conjunction with the embodiments.

[0033] The following examples are used to illustrate the present invention, but they cannot be used to limit the scope of protection of the present invention. The conditions in the examples can be further adjusted according to specific conditions. Simple improvements to the method of the present invention under the premise of the concept of the present invention belong to the scope of protection claimed in the present invention.

[0034] like Figure 1 and 2As shown, the present invention provides a simple, practical and multifunctional mouse fixing device, which includes a supporting base plate 1 and two fixing mechanisms 2 installed on the base plate 1 for fixing the head and hip of the mouse; the cross section of the base plate 1 is door frame-shaped, and the fixing mechanism 2 is capable of moving laterally on the base plate 1; the positioning mechanism 2 includes a supporting plate 21 with a door frame-shaped cross section, a connecting plate 22, a threaded rod 23 and a dovetail fixing clamp 24.

[0035] In order to enable the two support plates 21 to be moved to positions corresponding to the mouse head and hips as required, Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown, the support plate 21 is slidably mounted on the upper surface of the base plate 1, two guide grooves A11 corresponding to the two ends of the support plate 21 are symmetrically opened on the upper surface of the base plate 1, a fixing bolt A3 is arranged on the bottom surface of the base plate 1, a bolt hole A212 matching the fixing bolt A3 is arranged at each end of the support plate 21, and a plurality of equally spaced through holes 12 for the fixing bolt A3 to pass through are opened inside the guide groove A11. When in use, the fixing bolt A3 fixed on the support plate 21 is loosened, and then the support plate 21 is moved so that the two support plates 21 are respectively located at the head and hip positions of the mouse, and then the fixing bolt A3 is passed through the through hole 12 at the current position, so that the fixing bolt A3 is screwed into the screw hole A212, thereby fixing the support plate 21 on the base plate 1.

[0036] In order to facilitate operation, the bottom plate 1 and the support plate 21 are both made of transparent materials. During operation, the experimenter can intuitively observe the positions of the components, making the operation more convenient.

[0037] In order to facilitate the adjustment of the height of the dovetail fixing clip 24, the dovetail fixing clip 24 can effectively fix the head and hip of the mouse. Figure 1 and Figure 2 As shown, the connecting plate 22 is installed on the inner side of the supporting plate 21 so that the connecting plate 22 can slide up and down on the supporting plate 21; a threaded rod 23 is provided at the middle position of the upper surface of the supporting plate 21 and passes through the supporting plate 21 in the longitudinal direction, and a screw hole matching the threaded rod 23 is provided at the middle position of the upper surface of the supporting plate 21, and a dovetail fixing clip 24 is installed at the middle position of the lower surface of the supporting plate 21. When fixing the mouse, the threaded rod 23 is rotated so that the threaded rod 23 drives the connecting plate 22 to move up and down, thereby driving the dovetail fixing clip 24 to move up and down, so that the dovetail fixing clip 24 can contact the mouse, thereby fixing the mouse.

[0038] Among them, Figure 1 and Figure 5As shown, a guide groove B211 is provided on the inner side wall of the support plate 21, and guide blocks 223 adapted to the guide groove B211 are provided at both ends of the connecting plate 22. When the connecting plate 22 is moved, the connecting plate 22 slides up and down in the guide groove B211 through the guide blocks 223, so that the connecting plate 22 keeps moving up and down stably.

[0039] Among them, Figure 1 , Figure 2 and Figure 4 As shown, a bearing 221 composed of an outer ring, an inner ring and balls is fixedly installed at the middle position of the upper surface of the connecting plate 22. The outer ring of the bearing 221 is fixed to the upper surface of the connecting plate 22, and the inner ring can rotate in the outer ring under the action of the balls. The threaded rod 23 passes through the inner ring of the bearing 221 fixedly installed on the support plate 21. When adjusting the position of the connecting plate 22, the threaded rod 23 is rotated, and the threaded rod 23 is rotated on the connecting plate 22 under the action of the bearing 221, and the connecting plate 22 can be driven to move according to the up and down movement of the threaded rod 23.

[0040] To facilitate the experiment, the mice were effectively fixed, e.g. Figure 1 and Figure 4 As shown, the dovetail fixing clamp 24 comprises a support seat 241 fixedly mounted at the middle position of the lower surface of the support plate 21 and two dovetail clips 242 mounted on the inner side of the support seat 241 through a rotating shaft 243 and in opposite directions. The two ends of the rotating shaft 243 are fixed on the support seat 241, and the two dovetail clips 243 are hinged on the rotating shaft 243. A spring 244 is mounted on the outer wall of the rotating shaft 243, and the two ends of the spring 244 are respectively fixedly connected to the two dovetail clips 242; two sliders 222 capable of moving laterally along the lower surface of the support plate 21 are symmetrically mounted on the lower surface of the connecting plate 22, and the dovetail clips 242 are connected to the sliders 222 through a connecting rod 25, and the two ends of the connecting rod 25 are respectively hinged to the sliders 222 and the dovetail clips 242. When fixing a mouse, place the mouse inside the two dovetail clips 242, then move the two sliders 222 so that the dovetail ends of the dovetail clips 242 are clamped on the mouse's legs, clamp the two dovetail clips 242 on the mouse's body, and then fix the sliders 222 to fix the mouse.

[0041] Among them, Figure 4 and Figure 5As shown, the lower surface of the connecting plate 22 is provided with a limiting slot 224, the slider 222 is located in the limiting slot 224, the slider 222 is provided with a fixing bolt B2221 which longitudinally penetrates the lower surface of 222, and the inside of the limiting slot 224 is provided with a plurality of bolt holes B which are evenly distributed and matched with the fixing bolt B2221. After the dovetail clip 242 fixes the mouse, the fixing bolt B2221 is screwed into the screw hole B to fix the slider 222, thereby effectively preventing the mouse from escaping.

[0042] In addition, in order to effectively fix the mice and prevent their legs from interfering with the experimenters, Figure 1 and Figure 3 As shown, the mouse fixing device also includes a lead plug 4 in the shape of a plum blossom pile for fixing the limbs of the mouse, and the upper surface of the bottom plate 1 is provided with a plurality of plug holes 13 adapted to the lead plug 4, and the plurality of plug holes 13 are evenly distributed on both sides of the guide groove A11. After the mouse body is fixed, the four limbs of the mouse are fixed to the bottom plate 1 by using two lead plugs 4 respectively, so that the cap ends of the lead plugs 4 clamp the limbs of the mouse on the bottom plate 1, thereby effectively fixing the mouse and preventing the limbs of the mouse from moving around during work to affect the experiment.

[0043] When in use, first place the mouse on the base plate 1 below the dovetail fixing clip 24, then loosen the fixing bolt A3, and then push the support plate 21 so that the two support plates 21 are located correspondingly at the head and hip of the mouse. After the position of the support plate 21 is determined, fix the support plate 21 to the base plate 1 by the fixing bolt A3, and then rotate the threaded rod 23 so that the threaded rod 23 moves downward with the connecting plate 22. When the dovetail clip 242 contacts the mouse, then loosen the fixing bolt B2221 so that the slider 222 can slide on the connecting plate 22, keep rotating the threaded rod 23, and drive the connecting plate 22 to move downward. The dovetail end of the dovetail clip 242 is manually clamped on the mouse's leg, and then tighten the fixing bolt B2221. The slider 222 is fixed to the connecting plate 22 by the fixing bolt B2221, and then the mouse's limbs are fixed to the base plate 1 using the lead 4 to complete the fixation of the mouse.
