[0002] With the continuous development of automatic intelligence informatization, the automation of cooking equipment has gradually become a hot topic of concern. Some stir-frying robot machines have emerged on the market. For existing stir-frying robots, the service life of the chemical coating on the pot liner does not exceed 700 times. Therefore, after a certain period of use, the pot liner needs to be re-sprayed with a chemical coating. Especially for commercial stir-frying robots, if 100 dishes are made in a day, the pot liner needs to be disassembled for maintenance in a week. Generally, the pot liner is fixed to the rotating pot shaft by means of screws, threaded pressing covers, etc., and needs to be removed manually, which is time-consuming and laborious. The installation process also requires manual participation, and the manual disassembly and installation also increase the customer's usage cost and training cost. Summary of the Invention
