Compound Tool Patents (Class 294/23)
  • Patent number: 11318601
    Abstract: When the push handle is manipulated, the manipulation lever is pulled by the wire so that the tong portions are parted. When manipulation of the push handle is released, the tong portions are pressed against each other so that the item may be easily fixed between the tong portions. When the manipulation of the push handle is released, the tong portions are rotated and automatically clamp the item located therebetween so that it is unnecessary to continuously manipulate the push handle to fix the item between the tong portions and it is possible to reduce an amount of grip used as well as reducing a manipulation time of the push handle and to prevent fatigability accumulating in hands or damage to hands due to the reduction in manipulation time of the push handle.
