  • Patent number: 7461575
    Abstract: 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.

  • Patent number: 7330355
    Abstract: A fixed pillar with heat loss is a fixed pillar for losing heat. The fixed pillar with heat loss includes a metal body, a screw thread and a plurality of grooves. The metal body is a hollow body. The plurality of grooves is respectively set on two sides of the metal body and communicating with each other. The screw thread is set on one end of the metal body to fix a circuit or other electric devices. Air flows into one side of the metal body and then passes through the inner part of the metal body and last flow out from another side of the metal body. Accordingly, the metal body exchanges heat with the air to lose the thermal energy quickly.
