Tool connector having multiple seating positions
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 a plurality of work tools, 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; and
a stop located within the axial bore between the leading end of the shuttle and the locking assembly, the stop configured to prevent the shuttle from extending further than the extended position toward the tool locking mechanism, wherein the stop protrudes into the axial bore to engage the leading end of the shuttle;
wherein the tool connector is configured to hold a work tool of the plurality of work tools at one of a first seating position or a second seating position, wherein the shuttle is located at the extended position when the work tool is held at the first seating position and at the retracted position when the work tool is held at the second seating position.
2. The tool connector of claim 1 , further comprising:
a magnet extending from the leading end of the shuttle, wherein the magnet is configured to be magnetically coupled to an end of the work tool.
3. The tool connector of claim 2 , wherein the tool connector is capable of receiving the work tool from the tool receiving end to the first seating position while the locking assembly is in the locked position, wherein, when the work tool is at the first seating position, the work tool is prevented from being further inserted into the axial bore by interference with the tool locking mechanism and the end of the work tool is magnetically coupled to the magnet.
4. The tool connector of claim 3 , wherein, when the work tool is located in the first seating position, a majority of an attachment end of the work tool is located in the axial bore.
5. The tool connector of claim 4 , wherein the work tool has a length of about one inch.
6. The tool connector of claim 1 , wherein the tool connector is capable of receiving the 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 work tool is at the second seating position, the locking assembly can be moved to the locked position such that the work tool is engaged by the tool locking mechanism.
7. The tool connector of claim 6 , wherein the work tool comprises a circumferential groove.
8. The tool connector of claim 7 , wherein, when the 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 work tool.
9. The tool connector of claim 6 , wherein the work tool has a length of about two inches.
10. The tool connector of claim 1 , wherein the locking assembly is biased to the locked position.
11. The tool connector of claim 10 , wherein the locking assembly comprises a coil spring configured to bias the locking assembly to the locked position.
12. The tool connector of claim 1 , wherein the shuttle is biased to the extended position.
13. The tool connector of claim 12 , wherein the locking assembly comprises a coil spring configured to bias the shuttle to the extended position.
14. The tool connector of claim 1 , wherein the stop comprises an annular lip in the axial bore.
15. The tool connector of claim 14 , wherein the leading end of the shuttle comprises a circumferential groove configured to interface with the annular lip.
16. The tool connector of claim 15 , 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.
17. The tool connector of claim 1 , wherein a 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.
18. 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 work tool has a corresponding polygonal shape.
19. The tool connector of claim 17 , wherein each of the polygonal shape and the corresponding polygonal shape is hexagonal.
