WRENCH WITH SLIDBALE OPERATION MEMBERS FORMING MULITPLE CLAMPING OPTIONS

摘要

A wrench includes a body having two openings. The body has a chamber in which two operation members are movably located. Each operation member has a first jaw and a second jaw respectively formed on two ends thereof. The first jaws each have a first face protruding out from the first opening. The second jaws each have a second face protruding out from the second opening. Two resilient members are located in the chamber and bias the two operation members to let the two first jaws and the two second jaws are opened wide. The first and second jaws each have slots which are engaged with the lips on each of the openings. The first jaws protruding from the opening form an open wrench, and the second jaws protruding from the other opening form another open wrench.
