Abstract
A high strength wrench includes a wrench body, a quick detachable unit, and a first sleeve unit. The wrench body includes a fitting hole extending in an axial direction. The quick detachable unit includes a quick detachable member partially inserted into the fitting hole and a quick detachable assembly disposed on the quick detachable member. The first sleeve unit includes a first sleeve body disposed in the fitting hole and a first accommodation hole formed through the first sleeve body. When the quick detachable member is surrounded by the first sleeve unit, torque caused by turning the sleeve and added to the quick detachable member can be evenly distributed by the inner surface of the first sleeve unit to prevent the quick detachable member from being easily broken and reinforce the strength of bearing the torque.
