Open end wrench capable of fast driving

An open wrench capable of fast driving a workpiece, with the workpiece including an outer periphery having first, second, third, fourth, fifth, and sixth sides respectively having first, second, third, fourth, fifth, and sixth faces in a first rotating direction and respectively having first, second, third, fourth, fifth, and sixth force-receiving faces in a second rotating direction, with the open end wrench comprising, in combination:

• a body including a handle and a jaw portion formed on an end of the handle, with spaced first and second jaws formed on an end of the jaw portion opposite to the handle, with the first and second jaws and the jaw portion integrally formed as a single and inseparable component of a same material, with the jaw portion further including a throat intermediate the first and second jaws, with the first jaw including a front end and a rear end, with the rear end of the first jaw connected to the throat, with the second jaw including a front end and a rear end, with the rear end of the second jaw connected to the throat, with the throat and the first and second jaws together defining a wrenching space, with the wrenching space adapted to receive the workpiece, with the first jaw including a force-applying face facing the wrenching space, with the jaw portion further including an arcuate sliding groove facing the wrenching space, with the sliding groove including spaced, first and second support walls and an arcuate sliding wall extending between the first and second support walls, with a guide fixed in the sliding groove, with the guide including two ends fixed in the first and second support walls;
• a slide slideably received in the sliding groove, with the slide including a first side having an arcuate sliding face slideable along the sliding wall of the sliding groove, with the slide capable of driving the workpiece or sliding along the outer periphery of the workpiece, with the slide movable between an extended position and a retracted position, with the slide further including a second side opposite to the first side of the slide, with the second side of the slide located outside of the sliding groove and including a first wrenching face located on a front end of the slide, with the slide further including a top face and a bottom face, with the top face slideably abutting the first support wall, with the bottom face slideably abutting the second support wall, with the top and bottom faces symmetrically supported by the first and second support walls, with the slide further including an arcuate guiding slot extending from the top face through the bottom face, with the guide received in the guiding slot, preventing the slide from disengaging from the sliding groove, with the guiding slot including an abutting end and a pressing end, with the front end of the slide including two wings respectively extending away from the top and bottom faces, with each of the two wings including inner and outer faces, with the inner faces of the two wings adapted to drive the workpiece;
• and
• an elastic element mounted in the guiding slot and having two ends respectively abutting the guide and the pressing end of the guiding slot, with the elastic element urging the abutting end of the guiding slot to contact with the guide, biasing the slide to the extended position,
• wherein when the open end wrench drives the workpiece to rotate in a first direction, the slide is in the extended position, the outer face of each of the two wings is partially in contact with the second jaw, force imparted from the workpiece to the two wings is transmitted to the second jaw, the slide stably abuts the workpiece.
