As shown in FIGS. 1-3 , a multifunctional experimental mouse gripper includes a movable cage 10 , a bracket 20 and a control rod 30 .

The movable cage 10 comprises two first connecting rods 11 arranged side by side in the transverse direction and two second connecting rods 12 arranged side by side in the longitudinal direction between the two first connecting rods 11, the first connecting rods 11 and the second connecting rods The rods 12 have the same size, the first connecting rod 11 and the second connecting rod 12 are parallel, and the two first connecting rods 11 and the two second connecting rods 12 are distributed in a parallelogram. Both ends of the first connecting rod 11 are respectively connected to the two second connecting rods 12 through two third connecting rods 13, that is, the same ends of the two first connecting rods 11 and the two second connecting rods 12 pass through Four third connecting rods 13 are connected together, and the four third connecting rods 13 are also distributed in a parallelogram, and the two ends of the third connecting rods 13 are respectively hinged with the first connecting rod 11 and the second connecting rod 12 . Between the first connecting rod 11 and the second connecting rod 12, a first block 14 is arranged along the length direction, and between the four third connecting rods 13 at one end of the first connecting rod 11, a first block is arranged. Two block nets 15, preferably the first block net 14 and the second block net 15 are made of steel wire ropes, to avoid the possibility of being bitten off by experimental rats. The four third connecting rods 13 at the other end of the first connecting rod 11 encircle an entrance 100 for the experimental rat to enter the activity cage 10 .

The bracket 20 is roughly in the shape of a door, and the two first connecting rods 11 are slidably connected to the bracket 20 through the sliding rods 16 respectively. Preferably, each first connecting rod 11 is slidably connected to the bracket 20 through three sliding rods 16, Inevitably, the three sliding rods 16 are parallel to each other, and preferably the three sliding rods 16 are evenly distributed along the length direction of the first connecting rod 11 .

The control rod 30 is slidably connected to the bracket 20, and one end thereof is fixedly connected to the middle part of the second connecting rod 12, and the other end is a free end that can be pressed and pulled, that is, the control rod 30 in FIG. 1 The lower end is fixedly connected with the middle part of the second connecting rod 12, and the upper end passes through the bracket 20 and is located above the bracket 20.

Working principle: the experimenter holds the support 20 with his hand, keeps the control rod 30 in a suitable position on the support 20, so that the entrance 100 at one end of the movable cage 10 is larger (at this time, the entrance 100 is roughly rectangular), and then The experimenter drives the experimental rat into the activity cage 10 through the entrance 100, then the experimenter presses the control lever 30, and the control lever 30 pushes the second connecting rod 12 connected therewith to move downward, so that the activity cage 10 becomes approximately become flat shape, and now the experimental rat is restrained by the first block 14 arranged on four sides of the movable cage 10, keeping the position of the control rod 30 unchanged, the experimental rat can be kept in a restrained state, and then the tester can start from Various experimental operations are carried out on experimental mice at the mesh of the first block 14 . Since the size of the inner space of the activity cage 10 can be adjusted through the control rod 30 , the tightness of the experimental rats being restrained can be avoided by properly adjusting the position of the control rod 30 .

The experimental mouse gripper provided by the present invention can complete the gripping of the experimental mouse without directly grasping the experimental mouse by hand, thereby avoiding the occurrence of the experimenter being bitten by the experimental mouse, and the experimental mouse is caught It can also be fixed or secured quickly and conveniently, so as to facilitate subsequent various experimental operations on experimental mice.

As a further improvement of the above scheme, the control rod 30 is covered with a spring 40, the two ends of the spring 40 are respectively connected with the bracket 20 and the control rod 30, and the middle part of the control rod 30 is provided with a spring 40 for connecting with the control rod 30. The boss 31 connected with the spring 40, the spring 40 is a compression spring or a tension spring. Under the natural (initial) state, due to the effect of the spring 40, the entrance 100 of the movable cage 10 becomes a flat shape that can restrain the experimental mice, and then the experimenter presses down or pulls the control rod 30 upwards to make the entrance of the movable cage 10 100 becomes roughly rectangular, and when the experimenter drives the experimental mouse into the movable cage 10, the experimenter releases the control rod 30, and then under the action of the elastic potential energy of the spring 40, the movable cage 10 becomes flat again, Thereby the experimental mouse is restrained, and after the experimental mouse is restrained like this, the experimenter does not need to keep the position of the control rod 30 unchanged, but the position of the control rod 30 is kept constant by the spring 40, thereby facilitating the operation of the experimenter.

As a further improvement of the above solution, one end of the spring 40 is connected to the control rod 30 , and the other end is connected to the bracket 20 through an adjustment mechanism 50 . The base plate 51, and the guide rod 52 and the screw rod 53 that are arranged side by side and pass through the base plate 51 are preferably basically slidably connected with the control rod 30, and the guide rod 52 is fixed on the support 20 and connected to the base plate. 51 is slidably connected, and the screw 53 is rotatably disposed on the bracket 20 and one end thereof is threadedly connected with the base plate 51 . Through the adjustment of the adjustment mechanism 50, the position of the lower end of the control rod 30 changes in the initial state, so that the flatness of the movable cage 10 in the initial state can be adjusted, and then the degree of tightness of the experimental rat after being restrained can be adjusted.

As a further improvement of the above scheme, the first screen 14 includes a plurality of movable ropes 141 arranged in parallel along the length direction of the first connecting rod 11, and the two ends of the movable ropes 141 are connected to the movable ropes 141 through a slider 142 respectively. The first connecting rod 11 and the second connecting rod 12 are slidably connected, each of the first connecting rod 11 and the second connecting rod 12 has a chute along the length direction, and the two sliding blocks 142 are respectively mounted on the two chute slots. slide inside. By moving the position of the activity rope 141 to change the distance between adjacent activity ropes 141, the body area of the experimental rat exposed between the adjacent activity ropes 141 can be different, so as to adapt to different experimental requirements. Of course, the first screen 14 in this embodiment may only include a plurality of parallel movable ropes 141 , or may also include a plurality of parallel fixed ropes intersecting with the movable ropes 141 . The second blocking net 15 then is made of the net rope that criss-crossing arranges.

As a further improvement of the above scheme, the end of the slide bar 16 far away from the first connecting rod 11 is provided with a stopper 17 for preventing the slide bar 16 from separating from the bracket 20, no matter how the control lever 30 is operated, the slide bar 16 is always Keep slidingly connected with the bracket 20, thereby avoiding the trouble caused when the slide bar 16 slides off from the bracket 20. Preferably, the stopper 17 is detachably connected to the sliding rod 16, such as threaded.
