Bicycle crank extractor is a tool specifically designed for disassembling bicycle cranks. It mainly consists of a silver part and a black part. The silver part is used to remove the fixing nut of the crankshaft, while the black part is used to "push" the crankshaft out of the central axis, thus completing the disassembly work.

The working principle of the crank extractor is based on the lever principle. By using the silver part of the fixing nut, the crank fixing nut can be easily disassembled with the force of the lever. The black part serves as the top rod, which pushes the crankshaft out of the central axis through force transmission, achieving rapid disassembly of the crankshaft. This design not only improves work efficiency, but also reduces labor intensity
