| 发明名称 | Apparatus for rapid installation of threaded fasteners | ||
| 摘要 | An apparatus for rapid installation of threaded fasteners is provided. The apparatus includes a drive portion configured for being received by a rotary tool, a bit holder extending from the drive portion and configured for receiving a tool bit, the bit holder defining an elongate portion, and a sleeve configured for translatable movement along the elongate portion. The sleeve has a first extended position in which an end of the sleeve extends substantially beyond the tool bit and a retraction position in which the sleeve does not enclose the tool bit. A spring biases the sleeve into the extended position. Pressing of an end of the sleeve against a working surface imparts translation of the sleeve in a direction from the extended position towards the retracted position. | ||

| 主权项 | 1. An apparatus for rapid installation of threaded fasteners, comprising: a drive portion configured for being received by a rotary tool; a bit holder extending from the drive portion and configured for receiving a tool bit, the bit holder defining an elongate portion; a sleeve configured for translatable movement along the elongate portion, a locking assembly carried by the sleeve and configured for locking the sleeve relative to the elongate portion; a cylinder extending outwardly around the sleeve that is rotatable relative to the elongate portion; wherein the sleeve has an extended position in which an end of the sleeve extends substantially beyond the tool bit and a retracted position in which the sleeve does not enclose the tool bit and the sleeve is locked relative to the elongate portion by the locking assembly, wherein a spring biases the sleeve into the extended position, wherein the sleeve is placed in the locked position by rotation of the cylinder into engagement with the locking assembly, wherein pressing of an end of the sleeve against a working surface imparts translation of the sleeve in a direction from the extended position towards the retracted position, wherein the sleeve is rotatable 360 degrees relative to the drive portion. | ||
