Abstract

A tool device includes a handle and a driving shank having one end engaged into the handle and rotatably attached and coupled to the handle with a pivot shaft for allowing the driving shank to be rotated relative to the handle from a straight position in line with the handle to a position perpendicular to the handle to form a T-shaped driving tool device. The driving shank includes a number of depressions and the handle includes a spring biased detent member for engaging with either of the depressions of the driving shank and for anchoring the driving shank to the handle at selected angular positions. An actuating member is slidably received in the handle for actuating the detent member to engage with the driving shank.

Claims

1. A tool device comprising:

a handle and including a chamber formed therein and including a passage formed therein and communicating with said chamber of said handle, and

a driving shank including a first end engaged into said handle and rotatably attached and coupled to said handle with a pivot shaft for allowing said driving shank to be rotated relative to said handle,

said driving shank being rotated relative to said handle from a straight position in line with said handle to a position perpendicular to said handle to form a T-shaped driving tool device, said driving shank being received in said passage of said handle when said driving shank is in line with said handle, and

said handle including a spring member engaged between said first end of said driving shank and said handle for biasing said driving shank against said handle and for positioning said driving shank to said handle.

2. The tool device as claimed in claim 1, wherein said driving shank includes a plurality of depressions formed therein, and said handle includes a spring biased detent member for engaging with either of said depressions of said driving shank and for anchoring said driving shank to said handle at selected angular positions.

3. The tool device as claimed in claim 2, wherein said depressions of said driving shank are formed in an outer peripheral portion of said first end of said driving shank.

4. The tool device as claimed in claim 2, wherein said handle includes a channel formed therein for receiving said first end of said driving shank and includes a conduit formed therein for receiving said spring biased detent member.

5. The tool device as claimed in claim 1, wherein said handle includes an orifice formed therein for receiving said pivot shaft.

6. The tool device as claimed in claim 1, wherein said handle includes at least one catch extended into said passage of said handle for engaging with said driving shank and for anchoring said driving shank to said handle.

7. The tool device as claimed in claim 1, wherein said handle includes a plurality of cavities in an end portion thereof for receiving spare tool members therein, and a cover attached onto said handle for enclosing said cavities of said handle and for stably retaining said spare tool members in said cavities of said handle.

8. A tool device comprising:

a handle and including a chamber formed therein and including a passage formed therein and communicating with said chamber of said handle, and

a driving shank including a first end engaged into said handle and rotatably attached and coupled to said handle with a pivot shaft for allowing said driving shank to be rotated relative to said handle,

said driving shank being rotated relative to said handle from a straight position in line with said handle to a position perpendicular to said handle to form a T-shaped driving tool device, said driving shank being received in said passage of said handle when said driving shank is in line with said handle,

said driving shank including a plurality of depressions formed therein, and said handle including a spring biased detent member for engaging with either of said depressions of said driving shank and for anchoring said driving shank to said handle at selected angular positions, said handle including a channel formed therein for receiving said first end of said driving shank and including a conduit formed therein for receiving said spring biased detent member, and

said handle including a pathway formed therein and communicating with said conduit of said handle, an actuating member slidably received in said pathway of said handle and engaged with said spring biased detent member for biasing said spring biased detent member to engage with either of said depressions of said driving shank.

9. The tool device as claimed in claim 8, wherein said actuating member includes a recess formed in an outer peripheral portion thereof for receiving said spring biased detent member therein, said recess of said actuating member includes a deeper middle portion for receiving said spring biased detent member and for allowing said detent member to be disengaged from said first end of said driving shank and for allowing said driving shank to be rotated relative to said handle.

10. The tool device as claimed in claim 9, wherein said recess of said actuating member includes a shallower actuating portion for engaging with said spring biased detent member and for forcing said spring biased detent member to engage with either of said depressions of said driving shank.

11. The tool device as claimed in claim 9, wherein said actuating member includes a bore formed therein and communicating with said recess of said actuating member for forming a slot between said bore and said recess of said actuating member.

12. The tool device as claimed in claim 11, wherein said handle includes a spring member received in said pathway of said handle for biasing said handle to engage with said detent member.

13. The tool device as claimed in claim 12, wherein said spring member includes a biasing segment extendible into said recess of said actuating member through said slot of said actuating member for engaging with said detent member and for forcing said detent member to engage with either of said depressions of said driving shank.

14. A tool device comprising:

a handle and including a chamber formed therein and including a passage formed therein and communicating with said chamber of said handle, and

a driving shank including a first end engaged into said handle and rotatable attached and coupled to said handle with a pivot shaft for allowing said driving shank to be rotated relative to said handle,

said driving shank being rotated relative to said handle from a straight position in line with said handle to a position perpendicular to said handle to form a T-shaped driving tool device, said driving shank being received in said passage of said handle when said driving shank is in line with said handle, and

said handle including an orifice formed therein for receiving said pivot shaft, and said handle including an enclosing cap attached thereto to enclose said orifice of said handle and to shield said pivot shaft.

15. A tool device comprising:

a handle and including a chamber formed therein and including a passage formed therein and communicating with said chamber of said handle, and

a driving shank including a first end engaged into said handle and rotatably attached and coupled to said handle with a pivot shaft for allowing said driving shank to be rotated relative to said handle,

said driving shank being rotated relative to said handle from a straight position in line with said handle to a position perpendicular to said handle to form a T-shaped driving tool device, said driving shank being received in said passage of said handle when said driving shank is in line with said handle, and

said handle including at least one latch flap extended from said first end of said handle for partially enclosing said passage of said handle and for retaining said driving shank in said passage of said handle and for allowing said driving shank to be engaged into or out of said passage of said handle.
