Abstract
A tool for engaging a spark plug is provided. The tool includes a socket with an interior sidewall that forms at least a portion of a socket chamber. An insert may be positioned within the socket chamber. The insert has at least a rigid first component and a compliant second component configured to nest within the rigid first component.
Claims17
A socket for engaging a spark plug, the socket comprising:
- a tool engaging portion;
- and
- a workpiece engaging body coupled to the tool engaging portion, the workpiece engaging body having a sidewall that defines a socket chamber;
- and
- an insert positioned within the socket chamber, the insert having a first component comprising a first material and a second component comprising a second material;
- wherein the first component has an exterior surface that is coupled to the sidewall of the workpiece engaging body such that the insert is maintained within the socket chamber;
- wherein the second component is positioned within the first component;
- wherein the second component defines an opening that is surrounded by the first component and the second component;
- wherein the second material is more compliant than the first material and is positioned to engage an outer surface of the spark plug;
- and
- wherein, when a spark plug is inserted into the socket chamber, the spark plug is received within the opening;
- and
- wherein the second component defines a cylindrical structure comprising an exterior surface that engages the first component.
