[0003] The slewing bearing in the prior art mainly includes a bearing outer ring, a bearing inner ring and a rolling element. When in use, the rolling element is installed between the bearing outer ring and the bearing inner ring, and then cooperates with other components such as a worm to perform transmission driving.

[0004] However, in actual use, the outer ring and the inner ring of the bearing are installed with external parts through multiple mounting holes on their inner walls and bolts. Due to the large number of mounting holes, individual bolts need to be removed one by one during installation and disassembly, which is very inconvenient. Moreover, during installation and disassembly, multiple bolts are easily lost if placed randomly, which increases the cost of using parts. Utility Model Content
