Abstract
Various embodiments of a driving tool providing electrical with an insulated shaft are provided. In various embodiments, the shaft includes shanks that are separated, such as by a joint, to reduce the electrical connectivity between the shanks and thus between ends of the shaft. In various embodiments, the shaft is covered by one or more coatings of electrically resistant material.
Claims20
A driving tool comprising:
- a handle;
- and
- a shaft removably coupled to the handle, the shaft extending along a first longitudinal axis and including a first shank, a second shank, a joint, a first operative end extending from the first shank, and a second operative end extending from the second shank, the joint separating the first shank and the second shank, wherein at least a portion of the first shank is inserted in the handle when the second operative end is furthest from the handle and at least a portion of the second shank is inserted in the handle when the first operative end is furthest from the handle, wherein the joint is formed from an electrically insulating material and the joint is positioned between the first shank and the second shank to provide electrical insulation between the first shank and the second shank.
A driving tool comprising:
- a handle;
- and
- a shaft removably coupled to the handle, the shaft extending along a first longitudinal axis and comprising a first shank coupled to a second shank such that torque applied to a first end of the shaft is transmitted to a second end of the shaft opposite the first end with respect to the first longitudinal axis, wherein the first shank is formed from a first piece of metal material, and the second shank is formed from a second piece of metal material distinct and separate from the first piece of metal material, wherein the first shank is spaced apart from the second shank along the first longitudinal axis such that the first shank does not touch the second shank.
A driving tool comprising:
- a handle;
- and
- a shaft removably coupled to the handle, the shaft extending along a first longitudinal axis and including a first shank, a second shank, a joint, a first operative end extending from the first shank, a second operative end extending from the second shank, and a first coating circumferentially surrounding the first shank and a second coating circumferentially surrounding the second shank, wherein the first coating and second coating are formed from an electrically insulating material, the joint separating the first shank and the second shank, wherein at least a portion of the first shank is inserted in the handle when the second operative end is furthest from the handle and positioned to be used, and at least a portion of the second shank is inserted in the handle when the first operative end is furthest from the handle and positioned to be used.
