[0002] When replacing the bucket teeth of a hydraulic rock drill, the installation components of the bucket teeth are contaminated during long-term use, and rust and blockage occur, which is not conducive to replacement.

[0003] The main reason is that in the existing technology, the bucket teeth of the hydraulic rock drill are easily damaged during frequent use, so the bucket teeth need to be made detachable. When the bucket teeth are damaged, the bucket teeth and the bucket can be separated from each other and the bucket teeth can be replaced separately. However, in the process of disassembling and replacing the bucket teeth, it is found that the connection between the bucket teeth and the bucket is mostly fixed and positioned by bolts. However, during long-term use, mixtures such as soil and debris will be blocked at the installation of the bolts, and easily cause corrosion to the installation, resulting in the bolts being blocked and corroded and unable to be twisted, affecting the disassembly and assembly of the bucket teeth.
