  • Publication number: 20070222241
    Abstract: The present invention involves a multi-function hand-held tool having a handle portion, an extension portion, and an attachment portion. The handle portion includes a spring-loaded trigger. The extension portion includes an elongated flexible shaft enclosing a control rod that is attached to a triangular block. The attachment portion includes a fixed attachment member and a rotatable attachment member, each preferably having two protrusions located on one end for securely receiving various removable attachments, such as spark plug boot removal members, cutting members, and plier members. The elongated flexible shaft allows the positioning of the handle portion away from the attachment portion and potential harmful objects to help minimize injury to the user when exerting a force on the handle portion.

  • Patent number: 7243419
    Abstract: The present invention involves a spark plug boot removal tool having a handle portion, an extension portion, and a grasping portion. The handle portion includes a spring-loaded trigger. The grasping portion includes a fixed grasping member and a rotatable grasping member. The extension portion includes an elongated flexible shaft enclosing a control rod that is attached to a triangular block. When the grasping portion is positioned over a spark plug boot, the trigger is compressed, causing the control rod to pull the block, causing the rotatable grasping member to join with the fixed grasping member to clamp around the spark plug boot. Both grasping members have an angular bend that allows the user to position the elongated flexible shaft outside of the engine compartment when exerting a force on the handle portion to remove the spark plug boot, thus minimizing the risk of injury.
