| 20110277600 | Super High-Torque Open End Wrench Capable of Fast Driving - An open end wrench includes a jaw portion having first and second jaws. The first jaw includes a sliding groove slideably receiving a slide. When the jaw portion is not engaged with a workpiece, the slide is in a free position. When the jaw portion receives the workpiece but does not drive the workpiece, a buffering space is formed between an abutting end of the guiding slot and a guide fixed in the sliding groove. When the jaw portion drives the workpiece and deforms elastically, the body rotates relative to the workpiece, but the slide does not rotate together with the body due to the buffering space such that the end of the slide remains in surface contact with a face of the workpiece. Also, a buffering angle can be formed between a wrenching face on the slide and the face of the workpiece when the jaw portion receives the workpiece but does not drive the workpiece. | 11-17-2011 |
| 20110277599 | Open End Wrench Capable of Fast Driving - An open end wrench includes first and second jaws. The first jaw includes an arcuate sliding groove having an arcuate sliding wall. A slide is received in the sliding groove and includes an arcuate sliding face slideable along the sliding wall. An arcuate guiding slot is formed in the slide. A guide is fixed in the sliding groove and received in the guiding slot. The guiding slot includes an abutting end and a pressing end. The abutting end is in contact with the guide when the slide is in an initial position. A spring seat is mounted in the pressing end of the guiding slot. The spring seat includes a face pressing against the pressing end. An elastic element has two ends respectively abutting the guide and the other face of the spring seat for biasing the slide to the initial position. | 11-17-2011 |
| 20110308360 | Open End Wrench Capable of Fast Driving - An open end wrench includes first and second jaws. The first jaw includes an arcuate sliding groove having two support walls and an arcuate sliding wall between the support walls. A slide is slideably received in the sliding groove and includes an arcuate sliding face slideable along the sliding wall. Two wings respectively extend from top and bottom faces of the slide. Top and bottom extension faces extend from a wrenching face of the slide and are located on inner faces of the wings. A spacing is formed between an outer face of each wing and one of the support walls to avoid friction, allowing smooth movement of the slide between an extended position and a retracted position. | 12-22-2011 |
| 20120060655 | RATCHETABLE OPEN-ENDED WRENCH - The present invention discloses a ratchetable open-ended wrench comprising wrench body and retractable jaw member. The wrench body comprises head with two opposite jaws and a receiving hole. The inner surface of the receiving hole has a sunken slot with an inner circular arc surface. The retractable jaw member is slidably mounted in the sunken slot and has two opposite sides, and one side is directing to the receiving hole and has a second engaging portion. The retractable jaw member and the head are against with an elastic member. The retractable jaw member is able to move from a first position to a second position in the sunken slot, and is able to limit a workpiece to rotate in the receiving hole when at the first position and to allow the workpiece to rotate in the receiving hole when at the second position. | 03-15-2012 |
| 20110197720 | Open End Wrench Capable of Fast Driving - An open end wrench includes first and second jaws formed on a jaw portion. The first jaw includes an arcuate sliding groove having an arcuate sliding wall. A slide is received in the sliding groove and includes an arcuate sliding face slideable along the sliding wall. An arcuate guiding slot is formed in the slide. The sliding face, sliding wall and guiding slot are free of holes, grooves, and recesses. A guide is fixed in the sliding groove and received in the guiding slot. The guiding slot includes an abutting end and a pressing end. The abutting end is in contact with the guide when the slide is in an initial position not engaged with a workpiece. An elastic device has two ends respectively abutting the guide and the pressing end of the guiding slot for biasing the slide to the initial position. | 08-18-2011 |
| 20120272796 | Open End Wrench Capable of Fast Driving - An open end wrench includes first and second jaws. The first jaw includes an arcuate sliding groove having two support walls and an arcuate sliding wall between the support walls. A slide is slideably received in the sliding groove and includes an arcuate sliding face slideable along the sliding wall. Two wings respectively extend from top and bottom faces of the slide. Top and bottom extension faces extend from a wrenching face of the slide and are located on inner faces of the wings. When the open end wrench drives a workpiece to rotate, an outer face of each wing is partially in contact with the second jaw. Force imparted from the workpiece to the wings is transmitted to the second jaw. | 11-01-2012 |
