[0002] The rotating rod fatigue apparatus can be used for fatigue experiments, skeletal muscle relaxation experiments, central nervous system inhibition experiments, and other experiments that require the use of exercise to detect the effects of drugs, such as the impact of toxicity on exercise capacity, the impact of the lack of a certain substance in the body on exercise capacity, the impact of cardiovascular and cerebrovascular drugs on exercise capacity, etc. The basic principles and basic functions of this instrument can be developed and utilized in multiple directions.

[0003] Based on the above, the inventors found that during the test of the existing rotating rod fatigue instrument, small animals would produce excrement, which would contaminate the fatigue instrument. Moreover, the rotating rod, baffle and other components of the fatigue instrument were fixed in position and not easy to disassemble, which made subsequent cleaning more troublesome. Therefore, in view of this, the inventors studied and improved the existing structure and provided a rotating rod fatigue instrument for animal experiments that is easy to disassemble, in order to achieve a more practical purpose.

[0016] 3. Beneficial effects

[0017] Compared with the prior art, the advantages of the present invention are:

The clamping plates cooperate with the support frame to clamp and fix the clamping blocks. Compared with the existing technology, the clamping assembly is set up to quickly clamp the partitions, which facilitates the adjustment of the experimental spacing to adapt to different experimental conditions.
