Abstract

A multi-angle tool handle includes a handle device including a compartment longitudinally formed therein, and a through-hole formed thereon and in communication with the compartment. An embedding portion is defined in the compartment. A interconnecting element is disposed in the compartment and includes a pivoting end formed on an end thereof and having an embedding portion. A locking device is installed in the through-hole and includes an embedded end defined on an end thereof. A connecting device is pivotally coupled to another end of the interconnecting element. The locking device is moveable between a first position and a second position so that the connecting device can be operated to pivot relative to the handle device or not.

Claims

1. A multi-angle tool handle comprising:

a handle device including a compartment longitudinally formed therein and open to a side thereof, a through-hole formed on the handle device and in communication with the compartment and an embedding portion defined in the compartment;

an interconnecting element disposed in the compartment and including a pivoting end formed on an end thereof, with the pivoting end having an embedding portion, with the interconnecting element having another end opposite to the end;

a locking device installed in the through-hole and including an embedded end defined on an end thereof with the interconnecting element pivotably coupled to the handle device about a first pivot axis defined by the locking device;

wherein when the locking device is in a first position, the embedded end of the locking device engages with both the embedding portion of the handle device and the embedding portion of the interconnecting element;

wherein when the locking device is in a second position, the embedded end of the locking device engages with the embedding portion of the handle device and disengages from the embedding portion of the interconnecting element; and

a connecting device pivotally coupled to the end of the interconnecting element about a second pivot axis spaced from and parallel to the first pivot axis;

wherein the locking device further includes a receiving hole defined in the embedded end and an elastic element disposed between the receiving hole and the embedding portion of the handle device.

2. The multi-angle tool handle as claimed in claim 1, wherein the other end of the interconnecting element includes two connecting ends, with a spacing defined between the two connecting ends for receiving a pivoting end of the connecting device.

3. The multi-angle tool handle as claimed in claim 2, with each connecting end having a second hole, with the pivoting end of the connecting device having a pivoting hole corresponding to said second holes, with a pin coupling said pivoting hole to said second holes and defining the second pivot axis.

4. The multi-angle tool handle as claimed in claim 1, wherein the locking device further includes an annular groove formed thereon and a fastener disposed in the annular groove.

5. The multi-angle tool handle as claimed in claim 1, wherein the handle device further includes a socket formed on another end thereof and a cap coupled to the socket and adapted for storage of various kinds of bits.

6. The multi-angle tool handle as claimed in claim 1 further comprising a cavity formed on the connecting device, a pawl and a spring disposed in the cavity, and a sheath mounted on the connecting device and abutting with the pawl.

7. The multi-angle tool handle as claimed in claim 6, with the sheath forming a grove therein, with a C-clip received in the groove.

8. The multi-angle tool handle as claimed in claim 1, with the embedding portion of the handle device having a plurality of teeth formed on an interior periphery thereof.

9. The multi-angle tool handle as claimed in claim 1, with the embedding portion of the interconnecting element having a plurality of teeth formed on an interior periphery thereof.

10. The multi-angle tool handle as claimed in claim 1, with the embedded end of the locking device having a plurality of teeth formed on an outer periphery thereof.

11. A multi-angle tool handle comprising:

a handle device including a compartment longitudinally formed therein and open to a side thereof, a through-hole formed on the handle device and in communication with the compartment and an embedding portion defined in the compartment;

an interconnecting element disposed in the compartment and including a pivoting end formed on an end thereof, with the pivoting end having an embedding portion, with the interconnecting element having another end opposite to the end;

a locking device installed in the through-hole and including an embedded end defined on an end thereof with the interconnecting element pivotably coupled to the handle device about a first pivot axis defined by the locking device;

wherein when the locking device is in a first position, the embedded end of the locking device engages with both the embedding portion of the handle device and the embedding portion of the interconnecting element;

wherein when the locking device is in a second position, the embedded end of the locking device engages with the embedding portion of the handle device and disengages from the embedding portion of the interconnecting element; and

a connecting device pivotally coupled to the end of the interconnecting element about a second pivot axis spaced from and parallel to the first pivot axis, with the compartment having first and second inner surfaces selectively abutting with the connecting device and a positioning portion defined on the first inner surface disposing the pivoting end of the interconnecting element.

12. The multi-angle tool handle as claimed in claim 11, with the positioning portion separating the first inner surface into first and second sides, with the second side adjacent to the second inner surface.

13. The multi-angle tool handle as claimed in claim 12, wherein by operation of the locking device in the second position, the connecting device is positioned as to form the multi-angle tool handle as being L-shaped, with the front end of the connecting device abutting the first side of the first inner surface.

14. The multi-angle tool handle as claimed in claim 12, wherein by operation of the locking device in the second position, the connecting device is positioned as to form the multi-angle tool handle as being T-shaped, with the connecting device abutting the second side of the first inner surface and the second first inner surface respectively.

15. The multiple-angle tool handle as claimed in claim 11 with the pivoting end of the interconnecting element abutting with the positioning portion during pivotal movement of the interconnecting element relative to the handle device.

16. The multiple-angle tool handle as claimed in claim 15 with the positioning portion integrally formed in the compartment of the handle device of a same material which does not allow separation.
