Driving tool having adjustable holding device

Abstract

A driving tool includes a driving stem having two or more outer peripheral grooves, a holding device having a tubular member slidably engaged onto the driving stem, a detent slidably received in the tubular member, and an actuating device having a control ferrule slidably engaged onto the tubular member and having an actuator for selectively actuating the detent to engage with either of the peripheral grooves of the driving stem and for adjustably attaching the tubular member to the driving stem at any selected position and for allowing the user to hold the driving tool at suitable or selected position when the driving stem is driven or rotated relative to the tubular member.

Claims

1. A driving tool comprising: a driving stem including a first peripheral groove and at least one second peripheral groove formed in an outer peripheral portion thereof, and including a driving shank provided on one end thereof,a holding device including a tubular member having a bore formed therein for slidably receiving said driving stem and for allowing said tubular member to be moved along said driving stem, said tubular member including an orifice formed therein and communicating with said bore of said tubular member,a detent slidably received in said orifice of said tubular member, andan actuating device including a control ferrule slidably engaged onto said tubular member and having an actuator provided on said actuating device for engaging with said detent and for selectively actuating said detent to engage with either of said first peripheral groove or said at least one second peripheral groove of said driving stem and for adjustably attaching said tubular member of said holding device onto said driving stem at a selected position.

2. The driving tool as claimed in claim 1, wherein said control ferrule includes an inner peripheral depression formed therein for selectively receiving said detent and for allowing said detent to be selectively disengaged from said first and said at least one second peripheral grooves of said driving stem and for allowing said tubular member to be moved or adjusted along said driving stem.

3. The driving tool as claimed in claim 1, wherein said control ferrule includes a spring member received therein for engaging with said tubular member and for biasing said actuator of said control ferrule to engage with said detent.

4. The driving tool as claimed in claim 3, wherein said tubular member includes a retaining ring attached thereto and engaged with said spring member for retaining said spring member between said tubular member and said control ferrule.

5. The driving tool as claimed in claim 1, wherein said control ferrule includes a soft outer covering provided on an outer peripheral portion thereof for being comfortably held by a user.

6. The driving tool as claimed in claim 1, wherein said tubular member includes an outer peripheral recess formed in an outer peripheral portion thereof for forming a diameter-reduced neck portion and for slidably engaging with said control ferrule.

7. The driving tool as claimed in claim 1, wherein said tubular member includes a compartment formed therein and communicating with said bore thereof for receiving at least one gasket, said at least one gasket is engaged between said driving stem and said tubular member.

8. The driving tool as claimed in claim 1, wherein said driving stem includes a second detent slidably engaged in said driving shank, and an actuating rod slidably engaged in said driving shank and engageable with said second detent for selectively actuating said second detent to partially move out of said driving shank.

9. The driving tool as claimed in claim 8, wherein said actuating rod includes a depression formed therein for selectively receiving said second detent and for allowing said second detent to be selectively engaged into said driving shank.

10. The driving tool as claimed in claim 9, wherein said driving stem includes a spring member received therein for engaging with said actuating rod and for biasing said actuating rod to engage with said second detent.

11. The driving tool as claimed in claim 10, wherein said driving stem includes a barrel slidably engaged onto said driving stem and a bar extended into said driving stem and engaged with said barrel and engaged with said actuating rod for selectively moving said actuating rod relative to said driving stem and against said spring member and for allowing said second detent to be selectively received in said depression of said actuating rod.

12. The driving tool as claimed in claim 1, wherein said driving stem includes at least one magnetic attracting member detachably attached thereto.

13. The driving tool as claimed in claim 12, wherein said driving stem includes an opened lower portion having an inner thread formed therein, and said at least one magnetic attracting member includes an outer thread formed thereon for engaging with said inner thread of said driving shank and for coupling said at least one magnetic attracting member to said driving stem.

14. The driving tool as claimed in claim 1, wherein said driving stem includes a handle selectively attached to said driving stem for rotating said driving stem relative to said tubular member of said holding device.

15. The driving tool as claimed in claim 14, wherein said handle includes a stud, and a third detent slidably engaged in said stud, and an actuating rod slidably engaged in said stud and engageable with said third detent for selectively actuating said third detent to partially move out of said stud.

16. The driving tool as claimed in claim 15, wherein said actuating rod includes a depression formed therein for selectively receiving said third detent and for allowing said third detent to be selectively engaged into said stud.

17. The driving tool as claimed in claim 16, wherein said handle includes a spring member received in said stud for engaging with said actuating rod and for biasing said actuating rod to engage with said third detent.

18. The driving tool as claimed in claim 17, wherein said handle includes a barrel slidably engaged onto said stud and a bar extended into said stud and engaged with said barrel and engaged with said actuating rod for selectively moving said actuating rod relative to said driving stem and against said spring member and for allowing said third detent to be selectively received in said depression of said actuating rod.

19. The driving tool as claimed in claim 15, wherein said driving stem includes an engaging cavity formed therein for receiving said stud of said handle, and at least one opening formed in said driving stem and communicating with said engaging cavity of said driving stem for detachably coupling said stud of said handle to said driving stem.
