Abstract

Disclosed is a special-purpose valve core removal tool, including a tool body and a hexagon wrench with a tapered extractor. The tool body is detachably connected to the hexagon wrench and includes square opening portions, hexagon portions, and a clamping portion. Multiple square opening portions and hexagon portions of different specifications are arranged axially along the tool body. An internal hexagon through hole is formed in the middle section of the tool body. The internal hexagon through hole radially penetrates through the tool body. The clamping portion is radially arranged in the tool body and transversely moves along the internal hexagon through hole. The hexagon wrench is extendable to the internal hexagon through hole to be clamped with the clamping portion. Through the above structure, the problem that in a disassembling and assembling process, it is needed to replace tool heads with different sizes many times is solved.
