Model of the Pumping Unit: Exact casting and inventiveness. Assembly is always a form of industrial reproduction. The term "kowtow machine" refers to a type of oil extraction apparatus and equipment called a pumping unit that uses pressure to draw oil from a well.

Metal: Made of metal, precision casting using a CNC method, color-oxidized aluminum alloy, and actual machine craftsmanship on par with collection crafts.

Mechanical: The mechanical structure is presented in a classical manner, and the straightforward transmission mechanism is obvious at a glance, showcasing the elegance of the careful reasoning and robust machinery.

Design prototypes based on historically significant items and inventions that clearly demonstrate the machine's practical worth in use while laying out its fundamental principles of operation.

Classic: In the history of industrial science and technology, representative and nodal classic creations have served as models for product design. A scale model and extensive restoration are used for excellent works.

Technology: 219 pieces are all meticulously polished using specialized abrasive tools, interpreting human wisdom and longing in the age of big business.

Assembly: The parts must be put together piece by piece. The entire procedure is engaging and filled with experience, and it is comparable to expert assembly line workmanship.
