<p>An adjustable wrench with a system of dual-block and dual-slip-lock is disclosed. This system made possible the non-release, instant adjustment of opening and closing, reliable grip on workpiece and high efficiency. It is composed of: active orifice, main body, lock-block, small wrench-button and flat-tip screw. This adjustable wrench's active orifice and main body are coordinated by convex-slot track. The max. dia. from plane S to plane U of convex-block C and max. dia. from place J to place L of lock-block F exceeded the width of slide-slot N. Whereas the more force that active orifice received, the more pressure on two (2) sides of slide-slot N by dual extrusion that came from convex-block C and lock-block F to realize non-release.</p> |
