[0002] Animal experiment refers to scientific research conducted in the laboratory using animals in order to gain new knowledge about biology, medicine, etc. or to solve specific problems. Animal experiments must be conducted by or under the guidance of trained personnel with research degrees or professional technical capabilities.

[0003] Animal experiments as scientific experimental subjects have greatly promoted the development of life sciences. Their quality will directly affect the results of scientific research and the quality of drug production. Among them, the tissues and organs of laboratory mice are similar to those of humans. They are the best experimental subjects to replace humans and are currently the most widely used experimental subjects. Every year, tens of millions to hundreds of millions of experimental animals are used worldwide, of which 85%-90% are rodents.

[0004] During the experiment on laboratory mice, the mice are usually fixed on a simple operating platform with ropes. Since the mice are small and have thin limbs, they are easy to fall off when fixed with ropes, and it is not easy to operate. In addition, during the operation, the operating platform is parallel to the experimental table, and the angle of the operating platform cannot be changed. The experimenters cannot observe the mice in detail, and standing for a long time will also make the experimenters tired. Utility Model Content

[0008] As a preferred embodiment, a further technical solution of the utility model is:

[0009] The connecting seat and the screw are connected to each other, and there is an opening on the front of the universal joint to allow the screw to pass through, thereby pushing the ball head fixing block inside the universal joint to move; the base is connected to the universal joint through a threaded connection, and the universal joint ball head screw drives the platform fixing device to rotate within a certain angle. By rotating the side screw, the ball head fixing block moves upward to fix the ball head angle.

[0010] The adjusting structure is an adjusting base, and the anti-skid structure is an anti-skid pad, which is connected to the bottom of the base and has anti-skid patterns.

[0011] The rope collector is internally provided with a spring, a rope storage wheel and a rope.

[0012] The rope fixer is distributed on the platform track and can move along the track. The bottom is fixed by screws, and the top is provided with an opening. The screw passes through the opening from the top and is perpendicular to the opening.
