Tool connector having multiple seating positions

摘要

A tool connector generally includes a tool receiving portion configured for reciprocating between first and second work tool seating positions, wherein the tool receiving portion is normally biased to the first work tool seating position, and actuatable to the second work tool seating position. The tool connector further includes a magnetic mechanism in the tool receiving portion for providing magnetic force to engage a work tool in either of the first and second work tool seating positions, and a locking mechanism for lockingly engaging a work tool in the second work tool seating position.

1. A tool connector capable of releasably holding each of a first work tool at a first seating position and a second work tool at a second seating position, the tool connector comprising:
a shaft having an axial bore with a tool receiving end; a locking assembly coupled to the shaft and comprising a tool locking mechanism, wherein the tool locking mechanism protrudes into the axial bore when the locking assembly is in a locked position, and wherein the tool locking mechanism is retractable from the axial bore when the locking mechanism is in an unlocked position; a shuttle disposed within the axial bore such that a leading end of the shuttle is the closest end of the shuttle to the tool receiving end, wherein the shuttle is capable of being reciprocated from an extended position to a retracted position, wherein, when the shuttle is at the extended position, the tool locking mechanism is located between the shuttle and the tool receiving end; a stop located within the axial bore and configured to prevent the shuttle from extending further than the extended position toward the tool locking mechanism, wherein the stop is configured to engage the leading end of the shuttle; and a magnet extending from the leading end of the shuttle; wherein the tool connector is capable of receiving the first work tool from the tool receiving end to the first seating position while the locking assembly is in the locked position, wherein, when the first work tool is at the first seating position, the first work tool is prevented from being further inserted into the axial bore by interference with the tool locking mechanism, the shuttle is located at the extended position, and an end of the first work tool is magnetically coupled to the magnet, and wherein, when the first work tool is located in the first seating position, a majority of an attachment end of the first work tool is located in the axial bore; and wherein the tool connector is capable of receiving the second work tool from the tool receiving end to the second seating position while the locking assembly is in the unlocked position, and wherein, when the second work tool is at the second seating position, the shuttle is located at the retracted position, and the locking assembly can be moved to the locked position such that the second work tool is engaged by the tool locking mechanism.
