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.
