Suppose model_1 is read from file.

model_2 = model_1.copy()

if i modify model_2（fix variables or add constraints）, will model_1 still keep the original form?

  Yes, it should keep the original form.

  You may also add/remove constraints/fixations from a single model, which may be easier in some cases. See this other answer for more information.
