[0002] Oil drill bits are used for rock. They are designed to drill holes underground and bring rock samples and underground oil reservoirs to the surface. Oil drill bits usually consist of cutting structures, grooves, and lubrication and cooling systems to ensure a high-efficiency drilling process. In addition, the design of the drill bit also takes into account the adaptability of the drilling pipe and the characteristics of the underground rock to ensure safe and effective drilling operations.

[0003] A cleaning device is required during the maintenance of oil drill bits. Since oil drill bits vary in size, it is not convenient to adjust the cleaning spacing of the cleaning brush during use, and the drill bit may not be fully and efficiently cleaned, thus affecting the cleaning effect and work efficiency. At the same time, due to the influence of the cleaning brush spacing, some areas of the drill bit may not be fully cleaned, resulting in residual dirt or impurities on the surface of the drill bit, affecting its service life and performance. In addition, the need to frequently replace the cleaning brush or take other methods to try to adapt to drill bits of different sizes will increase the workload of the operator, as well as the time and labor costs required for the entire cleaning process.
