发明名称 Spark plug wrench for confined spaces
摘要 A spark plug installation and removal wrench comprising a short socket with a handle pivotally attached to the socket, forming a compact assembly that can access spark plugs in tight spaces. The socket may be rotated on the pivot axis to slip over the spark plug and down to engage and drive the spark plug. Lateral force on the handle may then rotate the socket to install or remove the spark plug. In one embodiment, the handle pivot axis may run through a clearance space for the spark plug, and the handle may have a U shape to avoid interference with the spark plug. An embodiment is disclosed wherein the handle may be attached with roll pins, rivets, screws or other pivot attachment hardware.
