    • The present disclosure relates to a hand-held tool that may be held in the palm of a hand, the hand-held tool being of adequate length and size to allow users to comfortably transfer the tool from a palm grip to a pen grip to maintain the use of the fingers and the thumb when the hand tool is stored in the palm. One or several storage housings are attached offset from a drive shaft housing for improved torque transfer from a hand to the tool head, integral storage of work pieces, optimized use of palm torque during use, and better overall grasping. The hand tool is also equipped with a retractable or nonretractable torque drive shaft designed to allow the fingers and thumb of a user to be rotated freely when the tool is in palm grip and capable of transmitting torque through the housing when an axial pressure force is placed along the drive shaft to engage the tool head with the housing. The drive shaft can also be reversed to create a prolongation shaft or placed in another opening of the housing. In yet another embodiment, a flexible shaft or a telescopic shaft can be used as a drive shaft to reach remote or offset locations. In another embodiment, a biasing element can be used as a grip to activate the drive shaft. In another embodiment, the drive shaft can be dissociated from the housing and used independently. In another embodiment, the drive shaft can be forced into a torque drive mode by locking the drive shaft into the housing or a holster while the hand tool is used. Finally a coupler is used to alternate between a freewheeling position and a coupled position.
    • 本公开涉及一种可以保持在手掌中的手持工具,手持工具具有足够的长度和尺寸,以允许使用者舒适地将工具从手掌握持转移到笔夹以保持 当手工工具储存在手掌中时,使用手指和拇指。 一个或多个存储壳体从驱动轴壳体偏移安装,用于改善从手到工具头的扭矩传递,工件的整体存储,在使用期间优化的手掌扭矩的使用以及更好的整体抓握。 手动工具还配备有可伸缩或不可收缩的扭矩驱动轴,其设计成使得当工具处于掌握时使用者的手指和拇指能够自由旋转,并且当轴向压力被放置时能够通过壳体传递扭矩 沿着驱动轴将工具头与壳体接合。 驱动轴也可以反向以产生延长轴或放置在壳体的另一个开口中。 在另一个实施例中,柔性轴或伸缩轴可以用作驱动轴以到达远程或偏移位置。 在另一个实施例中,偏置元件可以用作把手以激活驱动轴。 在另一个实施例中,驱动轴可以与外壳分离并独立使用。 在另一个实施例中,通过在使用手动工具的同时将驱动轴锁定到外壳或皮套中,驱动轴可以被迫进入转矩驱动模式。 最后,耦合器用于在续流位置和耦合位置之间交替。
