手动工具
摘要：
一种工具大致由手柄、与该手柄枢接的器具、第一磁性元件和第二磁性元件构成，其中第一磁性元件安装在器具上，其具有与相对于枢接的轴线沿圆周设置的路线相交的选定极性的磁场，而第二磁性元件安装在手柄上，其磁场的极性与所述与圆周路线相交的选定极性的磁场相同或相反，基于手柄与器具之间的角度关系，磁场将具有如下效果：第一相互作用，其不产生用于相对于手柄角向推压器具的原动力，第二相互作用，其产生用于相对于手柄角向推压器具的排斥原动力，以及第三相互作用，其产生用于相对于手柄角向推压器具的吸引原动力。
摘要（英）：

A tool generally consisting of a handle, an implement pivotally connected to the handle, a first magnetic element mounted on the implement having a magnetic field of a selected polarity intersecting a path disposed circumferentially relative to the axis of the pivotal connection and a second magnetic element mounted on the handle having a magnetic field of a polarity of one of the same or the opposite of the selected polarity intersecting the circumferential path whereby dependent upon the angular relationship of the handle and the implement, the magnetic fields will have the effect of one of a first interaction, producing no motive force for angularly biasing the implement relative to the handle, a second interaction producing a repellant motive force for angularly biasing the implement relative to the handle and a third reaction producing an attractive motive force for angularly biasing the implement relative to the handle.
