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 |
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 |
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 |

20090302084 | ADHESIVE TAPE CUTTER - An adhesive tape cutter includes a pair of fastening portions at the right and left sides such that both sides of an adhesive tape roll are enclosed by the fastening portions. The top of the fastening portions is fitted with an inclined resilient tongue and formed with a tape-guiding slot. A slide slot is formed in the side wall of the fastening portions in which a slider of a slide cap fits in such a way that a proper sliding action is achieved. Moreover, a plurality of resilient supports are integrally formed in a tape-receiving cavity defined by both of the fastening portions such that an adhesive tape roll may be constantly pushed by the resilient supports for creating a certain clamping relationship between the adhesive tape roll and the fastening portions. | 12-10-2009 |
20110048647 | Tape cutter blade with truncated trapezoidal sharpened teeh - A tape cutter blade has truncated trapezoidal sharpened teeth and a substantially triangular gap is formed between any two adjacent teeth. The sharpened teeth are capable of leaving uniform teeth on the severed end of a cut out portion of an adhesive tape after application of the tape. This has the benefits of being visually attractive, easy of applying the adhesive side of the tape onto an object to be sealed, and capable of cutting out adhesive tapes formed of foam or fiber. | 03-03-2011 |
20110114689 | Parallelepiped tape cutter - A parallelepiped tape cutter includes a cover comprising a top, two sides, a bottom flange, a blade at an open end of one side, a latching element on the other side, a concave member on an inner surface of the latching element, and a limit member on an inner surface of the other side adjacent to one end of the concave member; a support comprising a recessed rail on either side of a raised bottom, a bent first wall, a bent second wall separate from the first wall, a latch projecting out of one end of the second wall toward the first wall, the latch having a laterally protruded latching end proximate to one end of the first wall, a slit at the other end of the first wall, and an opening defined between the second wall and the slit; and a tape roll in the support. | 05-19-2011 |
