Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of experimental instruments, and particularly relates to a mouse grasping device. Background Art
[0002] Mice evolved from the house mouse. They are widely distributed around the world. After long-term artificial breeding and selection, they have become the most widely used and most studied mammalian experimental animals. When injecting drugs or giving injections to mice, it is necessary to grasp and fix the mice. However, during the experiment, grasping the mice sometimes causes them to bite the experimenter. Grasping directly by hand easily frightens the mice and causes them to bite the experimenters.
[0003] The patent with the application number 202122770861.6 discloses a flexible mouse grasping device, including a grip. A trigger is provided on the grip. There are finger depressions on the trigger. A fixing hole is provided at the end of the trigger. A transmission rope is installed on the fixing hole. An extension rod is installed at the end of the grip. The extension rod is a hollow tube. A connector is installed on the extension rod. A capture cover is installed on the connector. The inside of the capture cover is a hollow structure. A rotating shaft is provided at the connection between the connector and the capture cover. A gear is sleeved on the rotating shaft. The gear meshes with a rack. One end of the rack is connected to the transmission rope, and the other end is connected to a return spring. The return spring is fixed on the inner wall of the connector.
[0004] Although the mouse can be captured through the capture cover, when conducting experiments on the mouse, it is still necessary to open the capture cover and then capture and fix the mouse inside for the experiment. Therefore, during actual use, the experimenter still needs to directly capture with hands. And after the capture cover is opened, the mouse is prone to escape. If drug injection is only carried out through the grooves on the capture cover, the mouse is prone to struggle, resulting in injection failure, thus leading to poor practicability of the grasping device. Summary of the Utility Model
[0005] The technical problem to be solved by the utility model is to provide a mouse grasping device to solve the problems that the existing device still requires the experimenter to directly capture with hands, and after the capture cover is opened, the mouse is prone to escape. If drug injection is only carried out through the grooves on the capture cover, the mouse is prone to struggle, resulting in injection failure, thus leading to poor practicability of the grasping device.
[0006] To solve the above technical problems, the utility model provides the following technical solutions:
[0007] A mouse grabbing device comprises a mounting frame and a telescopic assembly fixed on the top of the mounting frame, wherein two arc-shaped grabbing frames that move toward each other are symmetrically mounted on the bottom end of the mounting frame through a driving assembly, elastic frames are detachably fixed to the inner walls of the two arc-shaped grabbing frames, and operating grooves penetrating the elastic frames are provided at both ends of the side walls of the two arc-shaped grabbing frames, a neck positioning protrusion is provided on the inner wall of one end of the funnel-shaped elastic frame, and an anti-slip protrusion is provided on the other end of the elastic frame, wherein a rubber pad is fixedly mounted on the inner wall of the arc-shaped structure of the elastic frame.
[0008] Optionally, the telescopic assembly includes a telescopic rod fixed to the top of the mounting frame and a gripping rod threadedly sleeved on the telescopic rod, and an anti-slip sleeve is embedded in the outer wall of the gripping rod.
[0009] Optionally, a movable plate is fixed to the top of the two arc-shaped grabbing frames, and the two movable plates are embedded in the mounting frame.
[0010] Optionally, the driving assembly includes a screw rod embedded in the mounting frame and a servo motor fixed to a side wall of the mounting frame, and a shaft of the servo motor is fixedly connected to the screw rod.
[0011] Optionally, both ends of the screw rod are rotatably inserted into the mounting frame via bearings, and the two ends of the screw rod with opposite thread directions are respectively threadedly connected to the two movable plates.
[0012] Optionally, a button is installed at the top of the grip, and the button is electrically connected to the servo motor.
[0013] Optionally, the outer walls of the two arc-shaped grabbing frames are both provided with protrusions, and the outer wall of the elastic frame is provided with screw holes.
[0014] Optionally, a bolt is installed on the side wall of the protrusion, and the bolt passes through the arc-shaped grabbing frame and is threadedly inserted into a screw hole.
[0015] Compared with the prior art, the utility model has at least the following beneficial effects:
[0016] In the above scheme, two symmetrical arc-shaped grasping frames are provided, and an elastic frame is detachably installed in the arc-shaped grasping frame. When grasping, the neck positioning protrusion at one end of the inner wall of the elastic frame fixes the mouse's neck, so that the mouse's head is exposed, and the anti-slip protrusion at the other end of the inner wall of the elastic frame positions the mouse's tail to prevent the mouse from escaping from the elastic frame. At the same time, the rubber pad arranged on the inner wall of the elastic frame has a certain elasticity, which avoids the situation that the mouse is injured during grasping. The exposed mouse head and the multiple operating grooves on the arc-shaped grasping frame facilitate experiments on the captured mice. The mice are fixed while being grasped, which avoids the situation that the mice are grasped and fixed for the second time in the experiment, thereby improving the practicality of the grasping device.
[0017] By providing a telescopic rod fixed to the mounting bracket and a grip rod threadedly sleeved on the telescopic rod, the telescopic rod is moved within it by rotating the grip rod, and the position of the grip rod is adjusted during the movement, facilitating the adjustment of the length of the grasping device and being applicable to grasping mice at different positions.
[0018] By rotatably arranging a screw rod in the mounting bracket, after the button on the grip rod starts the motor, the screw rod rotates. During the rotation of the screw rod, two moving plates move towards each other, and during the movement, two arc-shaped grasping frames are driven to grasp the mouse, facilitating the remote control of the arc-shaped grasping frames to grasp, fix, and release the mouse. At the same time, after removing the elastic frame through bolts, an elastic frame with a different inner diameter can be replaced, thereby being applicable to grasping mice of different sizes. By providing an operation slot on the arc-shaped grasping frame, after the mouse is fixed by the arc-shaped grasping frame, operations such as drug injection and injection on the mouse's body are facilitated through the operation slot.
