Various microscopes are used in experiments to observe biological sections, biological cells, bacteria, and living tissue culture, liquid sedimentation, etc. It can be seen that microscopic observation is widely used in cytology, parasitology, oncology, immunology, genetic engineering, industrial microbiology, botany, etc. However, microscopic observation still has some small difficulties.
[0003] Before observing the sample with a microscope in the experiment, a slide and a cover glass are used to make a sample. During sample making, the thumb is often pressed downward to press the slide to disperse the sample, so that the sample can be observed more obviously and clearly. However, the sample cannot be observed under the microscope due to crushing and deviation caused by uneven force control, inaccurate angle control, and other human factors during sample pressing. In addition, the excess sample squeezed out of the slide makes the surface of the slide slippery, which is easy to lose or shift, resulting in experimental failure, re-experiment, and affecting the experimental progress and efficiency. The existing sample pressing device cannot control and record the appropriate pressing force and can only press one sample at a time, which is low in efficiency. SUMMARY
