发明名称 Wrench with two pivotable sections
摘要 A wrench includes a handle with a first driving portion extending from one side of a first end of the handle and a pivotable section has one end thereof pivotably connected to a second end of the handle. A second driving portion extends from one side of the other end of the pivotable section. The first and second driving portions are able to engage with an object and the first driving portion can output a larger torque to loose or tight the object, and the second driving portion is used to output a smaller torque. The pivotable section is rotatable about a pivot for connecting the pivot section to the handle so that the user may hold the handle and rotate the pivot section continuously to remove the object from the hole where the object is engaged therewith.
