[0002] Animal experiments refer to scientific research conducted in laboratories using animals in order to gain new knowledge about biology, medicine, etc. or to solve specific problems. For example, if the clinical response of a drug needs to be obtained, the drug is usually injected into mice and then observed.

[0003] However, in the prior art, in order to obtain accurate clinical responses, physiologically healthy mice are usually injected. However, the bodies and nerves of such mice are usually relatively active. Direct injection of mice may cause the mice to resist. If the experimenters are not protected by protective devices, the mice are very likely to bite the experimenters' hands. Therefore, a new type of protective device for animal experimenters is needed. Utility Model Content

[0028] The fixing mechanism 3 includes a rotating plate 301, and two driving blocks 302 are fixedly installed at the bottom of the rotating plate 301, and a rotating drum 303 is movably inserted between the opposite sides of the two driving blocks 302, and two motors 304 are fixedly inserted on one side of the outer wall of the two driving blocks 302, and the output ends of the two motors 304 are respectively fixedly connected to one end of the outer wall of the two rotating drums 303, and the outer walls of the two rotating drums 303 are wrapped with a strap 305.

[0029] The effect achieved by the entire embodiment 1 is that food is placed in the feeding frame 5. When it is necessary to inject medicine into the mouse, the mouse is placed into the device body 1 through the operating slot 4. The mouse will be lured by the food to eat the food near the feeding frame 5. During the eating process, the body is inside the restraint belt 305. At this time, the motor 304 is quickly started to tighten the two restraint belts 305, thereby tightening and fixing the mouse. At this time, the experimenter can wear protective gloves, take out the syringe, insert it into the operating slot 4 to inject the mouse with medicine. If it is found that the angle is too bad during injection, the rotating plate 301 can be rotated to adjust the angle of the mouse, thereby injecting the mouse.

[0030] Embodiment 2, as Figure 1-Figure 8 As shown, two fixed shafts 306 are fixedly inserted into the inner surface wall of the rotating plate 301, and the outer surfaces of the two fixed shafts 306 are movably sleeved with guide rollers 307. Slots 7 are provided on both sides of the outer wall of the device body 1, and obstacles 8 are movably inserted into the inner surface walls of the two slots 7. One side of the outer wall of the two obstacles 8 is fixedly installed with a mounting plate 9, and one side of the outer wall of the two mounting plates 9 is fixedly installed with a handle 10. A fixed groove 11 is provided on the top of the device body 1, and a block 12 is movably inserted into the inner surface wall of the fixed groove 11. An electric telescopic rod 13 is fixedly installed on the top of the device body 1, and the electric telescopic rod 13 is fixedly installed on the top of the device body 1. The output end of the retracted rod 13 is fixedly connected to one side of the outer wall of the block 12, the outer wall of the block 12 is provided with a rope 14, and the rope 14 is in contact with the strap 305, the back surface of the device body 1 is provided with a baffle 15 through a hinge, the back surface of the device body 1 is fixedly provided with two first hook blocks 16, the inner surface walls of the two first hook blocks 16 are movably inserted with a first baffle 17, the outer surface wall of the device body 1 is movably provided with two closing plates 18 through a hinge, the front surfaces of the two closing plates 18 are fixedly provided with second hook blocks 19, the inner surface walls of the two second hook blocks 19 are movably inserted with second baffle bars 20.

[0031] The effect achieved by the entire embodiment 2 is that, by setting the obstacle 8, the space inside the device body 1 except the fixing mechanism 3 is conveniently blocked, so that when the mouse goes to the spreading frame 5, the mouse body can be just inside the rotating plate 301, which is convenient for the strap to tighten the mouse. Then, a rope 14 is set, so that when the device is not in use, the strap 305 is in an expanded state through the rope 14, so that when the mouse enters the rotating plate 301, the mouse can be inside the strap 305, which is convenient for tightening. Finally, a first baffle 17 and a second baffle 20 are set to fix the fixed baffle 15 and the closing plate 18 to prevent the mouse from escaping through the operating slot 4 and the discharge port 6.

[0032] The working principle of the whole device is as follows: first, put the food into the spreading frame 5 through the discharge port 6, take out the second baffle 20 from the second hook block 19, and open the closing plate 18, and then put the mouse into the device body 1 through the operating slot 4. The mouse will be lured by the food in the device body 1, and under the guidance of the obstacle 8, lie on the strap 305 of the rotating plate 301 to eat the food. At this time, the two motors 304 and the electric telescopic rod 13 can be started. The motor 304 will tighten the strap 305 during the guidance of the guide roller 307, and then the movement of the block 12 will directly restrain the mouse on the rotating plate 301 without the support of the rope 14 and the tension of the motor 304. At this time, the experimenter can hold the handle 10 to pull the two obstacles. Pull out the obstacle 8 to free up the space inside the device body 1, put on protective gloves and hold the syringe, and inject the mouse through the operating slot 4. If you find that the angle is very uncomfortable during injection, you can also rotate the rotating plate 301 to adjust the angle for injection. After the injection is completed, rotate the rotating plate 301 to the initial angle, and then put the obstacle 8 back to the initial position. Then you can close the closing plate 18 and fix it with the second baffle 20, then take the first baffle 17 out of the first hook block 16, then open the baffle 15, and put the cage containing mice on the discharge port 6. At this time, start the motor 304 to loosen the strap 305. The mouse will rush forward without the fixation of the strap 305 and enter the cage well containing mice through the discharge port 6 for recovery.
