摘要： A tubular body member has an interior hexagon socket end arranged to freely receive the hexagon end base of a spark plug. An elongated groove is provided in the hexagon socket end which receives a leaf spring secured at one of its ends and arranged to engage a portion of the hexagon base of a spark plug for releasably holding the spark plug in the wrench. The tubular body member also has a body portion of reduced diameter relative to the hexagon socket end, such reduced diameter portion allowing the wrench to be worked in tight places. The interior of the reduced diameter tubular body member is of sufficient size to receive a spark plug insulator portion with clearance therearound, and this reduced portion and the socket end of the wrench are dimensioned and arranged whereby an interior juncture therebetween is adjacent the locking collar of a spark plug which is mounted in the wrench, whereby lateral movement of the wrench relative to a spark plug can only produce forces against the spark plug against the locking collar. The tubular body member has a square opening at its end opposite from the hexagon socket end arranged for engagement by a ratchet drive mechanism. The leaf spring is secured in the groove by upset metal portions of the groove.
