  • Patent number: 8869658
    Abstract: In a multi-function tool structure, a body and a work rod are pivotally connected together and can form a folded and retracted state. Moreover, an elastically movable press button is disposed on the body and can link up a positioning pin movably inserted into the work rod. Thus, pressing the press button can release a lock between the work rod and the positioning pin so that the work rod is swingable, while releasing the press button can lock the positioning pin and the work rod together again. Thus, the work rod and the body can be folded and retracted to facilitate the storage and carrying. After the work rod is developed, it can form multiple included angles with respect to the body so that the requirements of different operation angles can be satisfied.

  • Patent number: 7509894
    Abstract: A power tool comprises a handle, a head pivotally coupling to the handle, an operating member disposed on the head, a positioning element installed in the head and biased with an elastic element for fixing the head in a desired position relative to the handle. The operating member has a pressing portion and a receiving portion. While the operating member is in a first position, the pressing portion of the operating member abuts against the positioning element to press the positioning element to engage to the handle so that the head is fixed in position relative to the handle; while the operating member is in a second position, the elastic element is released to push the positioning element toward the receiving portion of the operating member so that the positioning element disengages from the handle and the head can pivot relative to the handle freely.

  • Patent number: 7401538
    Abstract: This invention relates to an F figure wrench that comprises a holding rod, a moving part, a turning rod and a driving part. At one end of the holding rod, a concavity is made and two lugs are implemented; the concavity is made as a guide hole to accommodate the moving part, the lug holes of the two lugs are used as pivot holes for the driving part to be pivot-connected with the holding rod. Furthermore, a penetration is made on the holding rod and the moving part concentrically, and intersects through the concavity for installation of the turning rod. A cam eccentric to the turning rod axis is implemented on the turning rod; when the turning rod is turned, the moving part is pushed by the eccentric cam and moving along the guide hole in the holding rod.

  • Patent number: 7347127
    Abstract: A screwdriver handle includes a first handle part and a second handle part. An axle is formed on an end face of the first handle part and includes two receptacles each receiving a positioning member. The second handle part includes an end face pivotally connected to the end face of the first handle part and having a groove for receiving the axle. A positioning hole extends from a wall defining the groove through an outer periphery of the second handle part. One of the positioning members is biased into a retaining section of the positioning hole to position the second handle part. A control member is mounted in the positioning hole and movable to urge the positioning member in the receptacle aligned with the positioning hole into the receptacle, allowing the screwdriver handle to be switchable between an in-line state and an angled state.

  • Publication number: 20080066587
    Abstract: An improved wrench for loosening and tightening objects having flexibility in two different planes of movement. The flexible drive wrench consists of an adjustable handle capable of rotating to achieve different angles along with a flexible shaft comprising of numerous steel links. The handle rotates around the flexible links when the release is engaged and locks when the release is disengaged. In addition, the steel links allow for flexibility along another plane of movement. Numerous links are connected together to form a flexible wrench by inserting a stud with a rounded end into the slotted cavity of the next link with a mushroom head steel pin connecting them. To the last link of the flexible wrench is connected a link with an open-end wrench head, closed-end wrench head, ratcheting head, or other fastening tool head for the removal of fasteners such as bolts, nuts, and other fasteners.

  • Patent number: 7318366
    Abstract: A ratcheting tool including a handle formed with an integral yoke at a first end and a tool head coupled to the yoke at a pivot. The tool head has a toothed hub facing rearwardly of the pivot and into the yoke. A locking spool is rotatably carried in the yoke adjacent the toothed hub. The locking spool has a first face, a second face, and a first tooth extending along both the first face and the second face and engaging the toothed hub. The locking spool is rotatable between a first position in which the first face is adjacent the toothed hub, thereby locking the tool head in a selected angular position with respect to the handle, and a second position in which the second face is adjacent the toothed hub such that the tool head is pivotable about the pivot.

  • Publication number: 20070289413
    Abstract: A swiveling driver includes a handle portion and a head portion operatively coupled to the handle portion for selectively pivoting relative thereto. The head portion includes an implement and defines at least one detent. A yolk extends from the handle portion and includes a protrusion for selective engagement with the detent. The yolk is movable between a locked configuration in which the protrusion is received in a detent and a released configuration in which the protrusion is not received in a detent. The head portion may be moved freely when the yolk is at the released configuration for setting the angle of the head portion relative to the handle or be fixed at the locked configuration. When the head portion is fixed, the implement may be operated with either a driver bit or in a ratcheting motion.
