Having Pivoted Handle Section Patents (Class 81/177.7)
  • Patent number: 11052516
    Abstract: A folding flex ratchet having a handle that is joined to a ratchet head by an offset hinge that allows the handle to be selectively folded between an extended position for applying greater torque and a folded position in which the ratchet operates in spaces where access is minimal, somewhat like a palm ratchet. The ratchet head may include a generally L-shaped neck that provides an offset handle connection point that is offset in two directions from the ratchet head, both rearwardly and longitudinally. The handle, ratchet head and offset hinge are configured so that, when in the folded position, the handle is approximately centered over the ratchet head and the handle extends substantially parallel to the ratchet head.

  • 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: 8375829
    Abstract: A wrench includes a handle, a yoke, a shaft, a head, a mandrel, a first transmitting unit and a second transmitting unit. The shaft includes a first section securely connected to the handle and a second section rotationally inserted in the yoke. The head is pivotally connected to the yoke. The mandrel is inserted through the head. The first transmitting unit can be used to transmit a small torque to the mandrel from the handle spun relative to the yoke. The second transmitting unit can be used together with the first transmitting unit to transmit a large torque to the mandrel from the handle pivoted together with the yoke.

  • Patent number: 8347763
    Abstract: A wrench with a quick rotatable driving head includes a handle, a driving head and a quick-disengaging unit. The quick-disengaging unit is composed of a fixing member secured with the driving head, an operating member inserted through the handle and fitted around the fixing member, and a restraining element transversely provided between the fixing member and the operating member and the handle. The handle and the driving head can be separated by the quick-disengaging unit so that the driving head, with the quick-disengaging unit acting as a pivot, can quickly screw or unscrew a thread locking member, and the operating member can be restrictedly positioned on the fixing member by the restraining element, able to prevent the handle and the driving head from separating.
