Abstract

A driving device includes a hollow holding member having one portion that has a retaining section formed on an intermediate section of an inner periphery thereof. The retaining section includes two mutually facing stepped surfaces that together define a tapered space therebetween for securely holding one of two angled sections of a hexagonal wrench. The other portion of the holding member includes a bottom wall that includes a notch defined therein for securely holding the other of the angled sections.

4. The driving device according to claim 3, further comprising an outer sleeve mounted around the holding member to enclose the second retaining section of the holding member.

5. A driving device for holding and driving a hexagonal wrench having two angled sections, the driving device comprising:

a hollow holding member including a first portion, a second portion, and an intermediate section, each of the first portion and the second portion including a chamber defined therein, the intermediate section including a retaining section formed by two mutually facing stepped surfaces that together define a tapered space therebetween for securely holding one of the angled sections of the hexagonal wrench, each said stepped surface consisting of consecutively connected step sections of different lengths, the stepped surfaces defining the tapered space being configured by a plurality of aligned and partially overlapped hexagons of different sizes that are aligned in sequence according to the sizes thereof such that the two mutually facing stepped surfaces are capable of holding hexagonal wrenches of various sizes, a wall that defines a portion of an associated said chamber including a notch defined therein for securely holding the other of the angled sections of the hexagonal wrench.

6. The driving device according to claim 5, wherein each said notch has a central recessed section and two rectilinear sections provided on two sides of the central recessed section, respectively.

7. The driving device according to claim 5, wherein the holding member further includes a second retaining section formed on an outer periphery thereof, the second retaining section includes a plurality of spaced longitudinal grooves that extend along a longitudinal direction of the holding member for receiving said one of the angled sections of the hexagonal wrench.

8. The driving device according to claim 7, further comprising an outer sleeve mounted around the holding member to enclose the second retaining section of the holding member.

9. A driving device for holding and driving a hexagonal wrench having two angled sections, the driving device comprising:

a hollow holding member including a retaining section formed on an inner periphery thereof, the retaining section including two mutually facing stepped surfaces that together define a tapered space therebetween for securely holding one of the angled sections of the hexagonal wrench, each said stepped surface consisting of consecutively connected step sections of different lengths, the stepped surfaces defining the tapered space being configured by a plurality of aligned and partially overlapped hexagons of different sizes that are aligned in sequence according to the sizes thereof such that the two mutually facing stepped surfaces are capable of holding hexagonal wrenches of various sizes, and

an outer sleeve securely mounted around the holding member, the outer sleeve including a wall adjacent to the holding member, the wall including a notch defined therein for securely holding the other of the angled sections of the hexagonal wrench.

10. The driving device according to claim 9, wherein said notch has a central recessed section and two rectilinear sections provided on two sides of the central recessed section, respectively.

11. The driving device according to claim 9, wherein the holding member further includes a second retaining section formed on an outer periphery thereof, the second retaining section includes a plurality of spaced longitudinal grooves that extend along a longitudinal direction of the holding member for receiving said one of the angled sections of the hexagonal wrench.

12. A driving device for holding and driving a hexagonal wrench having two angled sections, the driving device comprising:
