Tips: What is a extension rod?
The extension rod is one of the indispensable tools in the spark plug socket set. In auto repair work, maintenance personnel can choose extension rods of different lengths, such as 75mm, 125mm, 150mm or 250mm. Its function is to install between the socket and the matching ratchet wrench. It is used to disassemble and replace the spark plug that is installed in deep position. Because the spark plug cannot be touched with socket and the ratchet wrench directly.
In addition, when disassembling the bolts and nuts on a flat surface, the tools will stick close to the operation surface, hindering the normal disassembly, and even causing safety accidents. The extension rod can lift the tool to a certain height from the flat surface, which is convenient for operation.
It is forbidden to use the extension rod as a punch, because the strike of the hammer will seriously deform the square tenon and square hole at both ends of the extension rod.
