Will the utility model patent drawings still be protected if they are optimized after they are authorized?

Also protected.

According to the provisions of the Patent Law, the patentee enjoys exclusive rights over its patent and can exclude others from manufacturing, using, selling, and importing its patented products without permission. The drawings of a utility model patent are one of the important materials when applying for a patent, and are used to clearly display the structure, shape, size and other information of the invention. Once a patent is granted, the patentee has the right to manufacture, use, sell, and import the patented product.
