[0044] In modern dining culture, the design and function of the dining table turntable have undergone significant evolution. Early dining table turntables mainly relied on a non-powered mode, i.e., diners needed to manually rotate the turntable to facilitate eating. Although this design is simple, frequent manual rotation can cause inconvenience when multiple people dine together. With the advancement of technology, electric turntables have emerged, which drive the rotation of the rotating seat through the built-in motor-driven rotating gear ring, greatly improving the dining experience of diners. This electric rotating dining table has been widely used in various restaurants and families due to its convenience and practicality. For high-end restaurants, electric rotating dining tables have almost become the standard configuration for hosting guests.

[0045] However, according to the applicant's research, in high-frequency use scenarios such as restaurants, electric turntables may be damaged due to heavy object accumulation, frequent rotation, or sudden eccentric force exerted by guests. These factors can cause damage to the internal structure of the electric turntable, such as damage or even breakage of the rotating wheel or gear ring structure, which can cause problems such as tilting or unsmooth rotation of the dining table surface. These problems not only affect the dining experience, but also increase the operating costs of the restaurant. When repairing damaged electric turntables, professional personnel are usually required for disassembly and inspection, and the entire internal structure needs to be replaced when the internal structure is damaged, which not only consumes time and effort, but also has high costs.
