Tool connector having multiple seating positions

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.

2. The tool connector of claim 1 , wherein the locking assembly is biased to the locked position.

3. The tool connector of claim 2 , wherein the locking assembly comprises a coil spring configured to bias the locking assembly to the locked position.

4. The tool connector of claim 1 , wherein the shuttle is biased to the extended position.

5. The tool connector of claim 4 , wherein the locking assembly comprises a coil spring configured to bias the shuttle to the extended position.

6. The tool connector of claim 1 , wherein the stop comprises an annular lip in the axial bore.

7. The tool connector of claim 6 , wherein the leading end of the shuttle comprises a circumferential groove configured to interface with the annular lip.

8. The tool connector of claim 7 , wherein the circumferential groove is further configured to prevent interference with the locking mechanism when the locking mechanism is in the locked position and the shuttle is in the extended position.

9. The tool connector of claim 1 , wherein the magnet extends from the leading end of the shuttle such that, when the shuttle is located at the extended position, the magnet extends axially beyond the tool locking mechanism in the axial bore.

10. The tool connector of claim 1 , wherein the second work tool comprises a circumferential groove.

11. The tool connector of claim 10 , wherein, when the second work tool is located at the second seating position and the locking assembly is moved to the locked position, the tool locking mechanism engages the circumferential groove of the longer work tool.

12. The tool connector of claim 1 , wherein the first work tool has a length of about one inch.

13. The tool connector of claim 1 , wherein the second work tool has a length of about two inches.

14. The tool connector of claim 1 , wherein the axial bore has a cross section that has a polygonal shape, and wherein an attachment end of the first work tool has a corresponding polygonal shape.

15. The tool connector of claim 14 , wherein each of the polygonal shape and the corresponding polygonal shape is hexagonal.
