摘要：Disclosed is a spanner which is generally used as a typical tool for tightening orreleasing a bolt. The spanner is capable of tightening or releasing a bolt continually inone direction by the effect of a toggle bar () pivotally mounted on a jaw of two jaws () ofthe spanner head in a state that the toggle bar is urged to pivot toward one direction. A
protrusion () is formed on a distal end of the other jaw of the spanner head for grippingan angular portion of the bolt head so that it is possible to prevent the spanner headbeing readily disengaged from the bold head.
