| 20100122610 | Adjustable Wrench That Clamp a Workpiece Exactly and Tightly - A wrench includes a handle, and a driving unit pivotally mounted on the handle. The handle has an end portion provided with a support surface. The driving unit includes a first jaw having a first end pivotally mounted on the end portion of the handle, and a second jaw having a first end pivotally connected with a second end of the first jaw and a second end that is movable to abut the support surface of the handle and the first end of the first jaw. Thus, the second end of the second jaw abuts the support surface of the handle tightly and closely so that the force applied by a user is transmitted to the wrench directly so as to drive the wrench to operate the workpiece in an energy-saving manner. | 05-20-2010 |
| 20100282028 | Adjustable wrench - An adjustable wrench is provided for selectively producing a fixing movement or a pivotal turning movement by pressing or releasing a stop module to pivot the pivotal jaw, so that the adjustable wrench can change the width of its opening quickly, and such adjustable wrench provides an excellent operation and also reduces the operating time greatly. | 11-11-2010 |
| 20130160613 | DRIVING TOOL - A driving tool ( | 06-27-2013 |
| 20130247724 | RATCHET WRENCH APPLICABLE TO MULTI-SIZE WORKPIECES - A ratchet wrench applicable to multi-size workpieces comprises: a wrench with a handle and a head wherein the head has a hollow handle hole in which there are two neighboring surfaces along its inner edge, a first support surface and a second support surface, and an accommodating space embedded into the handle; a support portion with a ratchet part and a resilient member wherein the ratchet part allows one end to be pivoted in the accommodating space and is provided with an arc-convex portion, which is within the hollow handle hole for a first working space developed inside, and the resilient member always exerts a resilient resistance on the ratchet part. As such, the ratchet wrench depends on a simple mechanism and is applicable to continuous screw operation of various screw fastening elements for excellent convenience and swiftness. | 09-26-2013 |
| 20140053691 | Nut and Fitting Strike Adapter and Method of Utilizing the Same - An adapter encircles and locks around nut members of pipe unions or nuts made up on fasteners, or cylindrical members, and engages the nut member or cylindrical member in locking contact. The adapter has strike surfaces which allow the nut member or cylindrical member to be tightened or loosened by a hammering means, such as a hammer, mallet or sledge hammer. Thus, in the case of a pipe union, the device temporarily converts a nut union to a hammer union. The apparatus is configured to facilitate attachment of the device in tight situations, such as attaching the device to the nut member of a pipe union, or to a fitting, within a piping manifold having closely spaced parallel pipelines. | 02-27-2014 |
| 20140076112 | ADJUSTABLE WRENCH - The present invention relates to an adjustable wrench. The adjustable wrench comprises a handle part, a curved jaw part, a linkage part, an adjusting element and a restoring element. The handle part comprises a toothed portion. The curved jaw part is pivotally connected to the handle part. When the adjusting element is pushed by an external force, the adjusting element further moves the linkage part simultaneously, and the linkage part pulls the curved jaw part to rotate so as to adjust a size of an opening between the curved jaw part and the toothed portion. Accordingly, the present invention has advantages and effects of fast and simple adjustment for use and a lever arm thereof being adjustable for labor saving, etc. | 03-20-2014 |
| 20140144294 | Adjustable Open End Ratcheting Flare Wrench - The invention comprises a ratchet style flare nut wrench which incorporates an assembly to provide a torqueing function and ratchet effect. The assembly includes a wrench body capable of providing torque delivery through three rotating cylindrical cams which contact the nut. The cylindrical cams then rotate when reversing the direction of the wrench assembly so that a cutout portion of the cylindrical cams allows the nut points to pass by. Two cylinder cams are mounted on movable guide blocks which adjust the wrench for different size nuts. | 05-29-2014 |
| 20150101457 | ADJUSTABLE WRENCH - An adjustable wrench is provided. The adjustable wrench includes a main body extended and formed with a fixed jaw having a first clamping face. An arc-shaped sliding space is formed between the main body and the fixed jaw. A gear member is rotatably disposed in the main body. A part of the gear member is revealed for allowing the teeth to partially reach to within the sliding space. An end of the movable jaw is pivotally connected to a free end of the fixed jaw. A guiding rib of the movable jaw has a toothed row to mesh with the gear member. The movable jaw has a second clamping face, and a clamping space is formed between the first and second clamping faces. When the gear member is driven by a tool to rotate, the clamping space can be quickly adjusted. | 04-16-2015 |
| 20150114185 | Open-End Ratcheting Wrench - The present invention may be used for rotating a polygonal object. A first wrench member may have a handle with two ends with a fixed jaw attached at a first end and with a cavity formed in the fixed jaw and first end. A second wrench member may be a movable jaw with a curved jaw attached to a ratcheting element. The ratcheting element may be slidably positioned in the cavity to position the curved jaw opposite the fixed jaw. The second wrench member may be constrained by the cavity and a cavity insert member to slide in said cavity about the center of an arc. The cavity insert member is positioned between a rearward wall of the cavity and the ratcheting element and retains the ratcheting element within the cavity. | 04-30-2015 |

| 20150059535 | Locking V Hinge Tool Device - The locking V hinge tool of this invention comprises three or more pieces. The first two pieces are fundamentally identical and reversed, comprised of three main sections in optional order of, a jaw end, a common axle, and a arc-like cam, assembled together and rotate through the common axle, allowing the jaw ends to open and close. A third pin holding piece holds a pin that rides in and moves, the criss-crossing arc-like slots in the other pieces, at or near an angle aimed at the corners of a diamond like opening where the two arc-like slots intersect. Any external force exerted on the jaw ends, attempt to force the pin in the arc-like slots to rise to an upright position but are blocked by the walls. | 03-05-2015 |
