Abstract
A drive extension wrench is disclosed that includes a first end having a first connecting structure and a second end having a second connecting structure. A shaft defining a longitudinal rotational axis connects the first and second ends. Rotation of the first connecting structure along a first rotational axis is transferred through the shaft to cause rotation of the second connecting structure along a second rotational axis. In some embodiments, the wrench includes a housing that is separable at a coupling area to expose a portion of the shaft, allowing the shaft to be driven directly or to function as a modular attachment.
Claims20
A drive extension wrench, comprising:
- a first end comprising a first connecting structure and defining a first rotational axis;
- a second end comprising a second connecting structure and defining a second rotational axis;
- and
- a shaft defining a third rotational axis and being connected to the first connecting structure and the second connecting structure, wherein a third rotation of the shaft along the third rotational axis causes a first rotation along the first rotational axis and a second rotation along the second rotational axis.
An apparatus, comprising:
- a first rotating means defined at a first end of the apparatus and comprising a first connecting structure;
- a second rotating means defined at a second end of the apparatus and comprising a second connecting structure;
- and
- a third rotating means connecting to the first rotating means and the second rotating means, wherein rotation of the first connecting structure is transferred to the second connecting structure via the third rotating means.
A drive extension wrench, comprising:
- a first end comprising a first connecting structure and defining a first rotational axis;
- and
- a shaft defining a second rotational axis and being operably connected to the first connecting structure at a first end, wherein the shaft comprises a second connecting structure at a second end, and wherein a first rotation of the second connecting structure along the second rotational axis causes a second rotation of the first connecting structure along the first rotational axis.
