Claims
- 1. In a holder for a tool element which has a tool receptacle extending from one end thereof and an interior end within said holder for the removable reception of a tool within said receptacle, the improvement which comprises an elongated blind slot extending axially along the length of said holder with a depth to about the centerline of said holder and an arcuate bottom, and intersecting said receptacle adjacent its interior end, to expose the received end of said tool, whereby an element can be inserted into said slot into contact with said received end of said tool and moved axially along said holder for forced ejection of said tool from said receptacle.
- 2. The holder of claim 1 wherein said holder member has a cross bore which intersects said receptacle, with a ball seated in said cross bore and wherein said tool has an annular groove about its shank which provides a recess for said ball.
- 3. The holder of claim 1 wherein said receptacle has at least one flatted interior wall, and the shank of said tool has a mating cross section.
- 4. The holder of claim 1 in combination with a wrench having a rotationally driven member having a distal socket and a central through bore with said holder slidably received in said through bore and rotationally restrained therein.
- 5. The holder of claim 4 including a spring retainer carried on said wrench and engaged with said holder to rotationally restrain said holder.
- 6. The combination of a rotational wrenching tool which comprises a rotationally driven member that distally supports a socket and has a central through bore, an elongated tool holder slidably received in said through bore and having a tool receptacle extending from one end thereof with the interior end of said tool receptacle terminating within said holder, a tool with its shank end removably received within said tool receptacle, and an elongated blind slot extending axially along the length of said holder with a depth to about the centerline of said holder and an arcuate bottom, and intersecting said tool receptacle adjacent its interior end, to expose the received end of said tool, whereby an ejection element can be inserted into said slot into contact with said received end of said tool and moved axially therein for forced ejection of said tool from said receptacle.
- 7. The combination of claim 1 including detent means to secure said tool element within said tool receptacle which comprises a cross bore in said holder intersecting said tool receptacle adjacent its interior end, with a detent ball seated in said cross bore.
- 8. The combination of claim 7 wherein said tool element has an annular groove about its shank end which, when aligned with said cross bore provides a recess for said ball, whereby said ball serves as a detent to retain said tool element within said tool receptacle.
- 9. The combination of claim 7 wherein said tool receptacle has at least one flatted interior wall, and the shank of said tool has a mating cross section.
- 10. The combination of claim 9 wherein said holder is slidably received in said through bore and rotationally restrained therein.
- 11. The combination of claim 10 including a spring retainer carried on said wrench and engaged with said holder to rotationally restrain said holder.
- 12. The combination of claim 11 wherein said rotationally driven member has external gear teeth for driving engagement with gear means internally mounted in said wrench.
- 13. The combination of claim 12 including power means carried in said wrench to drive said rotationally driven member.
- 14. The combination of claim 7 wherein said tool element is a key having a work end with wrenching flats to be received in a socket of a fastener element.
- 15. The combination of claim 14 wherein said fastener element is a bolt having a socket in its threaded end to receive said key.
