The handle 12 has a shaft support 28 which is positioned within the handle 12.

A lever 30 is pivotally disposed on the handle 12 and the lever 30 can be manipulated by the user. The lever 30 is urgeable into an engaged position and the lever 30 is biased into a disengaged movement. The lever 30 has a coupled end 32 and a free end 34, and the coupled end 32 is positioned in the pivot hood 26. The lever 30 includes a pin 36 which extends through the pivot hood 26 and engages the lever 30 such that the lever 30 is pivotally coupled to the pivot hood 26. The lever 30 lies against the outer wall 18 of the handle 12 when the handle 12 is in the engaged position. Conversely, the lever 30 angles away from the outer wall 18 when the handle 12 is in the disengaged position. A biasing member 38 is integrated into the pivot hood 26, the biasing member 38 engages the lever 30 and the biasing member 38 biases the lever 30 into the disengaged position.

A shaft 40 is rotatably disposed in the handle 12 and the shaft 40 extends outwardly through the handle 12. The shaft 40 has an exposed end 42 with respect to the handle 12 and a coupled end 44. The shaft 40 extends through a bearing 4 in the hole 22 in the first end 14 of the handle 12 and the exposed end 42 is open into a polygonal receiving well 45. The coupled end 44 of the shaft 40 rotatably engages a bearing 46 in the shaft support 28 in the handle 12 such that the shaft 40 is rotatable about an axis extending between the exposed end 42 and the coupled end 44 of the shaft 40.

A plurality of bits 48 is provided and each of the bits 48 is insertable into the shaft 40 to engage a respective type of fastener 50. The fastener 50 may be a Phillips head screw, a slotted screw or any other type of threaded fastener 50 that has one of a plurality of conventional heads. Each of the bits 48 is insertable into the exposed end 42 of the shaft 40. Each of the bits 48 has an outer surface 51 comprising a plurality of intersecting sides 52 such that the outer surface 51 conforms to a bounding surface 54 of the polygonal receiving well 45. In this way the shaft 40 can rotate the bit 48 that is positioned in the exposed end 42. The plurality of bits 48 might include Phillips bits, torx bits, slotted bits and any other bits that are commonly associated with cordless drill bits, for example.

A gear 56 is positioned around the shaft 40 and the gear 56 is in mechanical communication with the lever 30. The gear 56 is rotated when the lever 30 is urged into the engaged position thereby facilitating the shaft 40 to be rotated. In this way the bit in the shaft 40 can rotate the fastener 50. The gear 56 has a top side 58 and a bottom side 60, and the top side 58 has a plurality of first teeth 62 that is each integrated into the top side 58. The first teeth 62 are spaced apart from each other and are distributed around the top side 58. Each of the first teeth 62 has a front surface 64 and a top surface 66, and the front surface 64 extends upwardly from the top side 58. Furthermore, the top surface 66 slopes downwardly between the front surface 64 and the top side 58.

The bottom side 60 has a plurality of second teeth 68 that is each integrated into the bottom side 60. The second teeth 68 are spaced apart from each other and are distributed around the bottom side 60. Each of the second teeth 68 has a front surface 70 and a bottom surface 72, and the front surface 70 of the second teeth 68 extends downwardly from the bottom side 60. Additionally, the bottom surface 70 slopes upwardly between the front surface 70 of the second teeth 68 and the bottom side 60.

A direction selector 74 is movably integrated into the lever 30 and the direction selector 74 is in mechanical communication when the gear 56. The direction selector 74 is positionable in a tightening condition to facilitate the gear 56 to rotate in a first direction when the lever 30 is urged into the engaged position to tighten the fastener 50. Conversely, the direction selector 74 is positionable in a loosening condition thereby facilitating the gear 56 to rotate in a second direction when the lever 30 is urged into the engaged position to loosen the fastener 50.

The direction selector 74 includes a switch 76 that is pivotally disposed in the lever 30. The direction selector 74 includes a first arm 78 that is coupled to the switch 76 such that the first arm 78 extends into the interior of the handle 12. The first arm 78 has a distal end 80 with respect to the switch 76 and a lower surface 82. The lower surface 82 has a plurality of teeth 84 that are distributed from the distal end 80 toward the switch 76. The teeth 84 on the lower surface 82 are aligned with the top side 58 of the gear 56. The first arm 78 is lowered onto the top side 58 of the gear 56 when the switch 76 is positioned in a tightening position.

Additionally, the teeth 84 on the lower surface 82 engage the first teeth 62 when the first arm 78 is lowered onto the top side 58. The teeth 84 on the lower surface 82 engage the front surface 64 of the first teeth 62 when the lever 30 is urged into the engaged position such that the first arm 78 rotates the gear 56 in a first direction. Conversely, the teeth 84 on the lower surface 82 slide over the top surface 66 of the first teeth 62 when the lever 30 is biased into the disengaged position such that the gear 56 is not rotated.

The direction selector 74 includes a second arm 86 that is coupled to the switch 76 such that the second arm 86 extends into the interior of the handle 12. The second arm 86 has a distal end 88 with respect to the switch 76 and an upper surface 90. The upper surface 90 has a plurality of teeth 92 that are distributed from the distal end 80 toward the switch 76 and the teeth 92 on the upper surface 90 are aligned with the top side 58 of the gear 56. The second arm 86 is raised onto the bottom side 60 of the gear 56 when the switch 76 is positioned in a tightening position and the teeth 92 on the upper surface 90 engage the second teeth 68 when the second arm 86 is raised onto the top side 58.

The teeth 92 on the upper surface 90 engage the front surface 70 of the second teeth 68 when the lever 30 is urged into the engaged position such that the second arm 86 rotates the gear 56 in a second direction. Conversely, the teeth 92 on the upper surface 90 slide over the bottom surface 72 of the second teeth 68 when the lever 30 is biased into the disengaged position such that the gear 56 is not rotated. Each of the first arm 78 and the second arm 86 is positioned on opposite sides of the shaft 40 with respect to each other.

A blade 94 is slidably disposed in the handle 12 and the blade 94 is extendable outwardly through the slot 24 in the second end 16 of the handle 12 for cutting with the blade 94. The blade 94 is retractable into the interior of the handle 12 for storing the blade 94. A blade switch 96 is provided and the blade switch 96 is slidably integrated into the outer wall 18 of the handle 12. The blade switch 96 is slidable along an axis extending between the first end 14 and the second end 16 of the handle 12. Additionally, the blade switch 96 is in mechanical communication with the blade 94 for extending or retracting the blade 94. The blade 94 may be longitudinally elongated and the blade 94 may have an angled cutting edge.

In use, a respective one of the bits 48 is inserted into the shaft 40 to facilitate the respective bit 48 to engage the fastener 50. The direction selector 74 is positioned in the tightening condition and the lever 30 is alternatively urged into the engaged position and released. In this way the shaft 40 is rotated in a clockwise direction, each time the lever 30 urged into the engaged position, in order to tighten the fastener 50. The direction selector 74 is positioned in the loosening condition and the lever 30 is alternatively urged into the engaged position and released. In this way the shaft 40 is rotated in a counterclockwise direction, each time the lever 30 is urged into the engaged position, in order to loosen the fastener 50. Thus, the fastener 50 can be loosened or tightened in the convention of employing a screwdriver without requiring the user to manually rotate their wrist.

With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of an embodiment enabled by the disclosure, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by an embodiment of the disclosure.

Therefore, the foregoing is considered as illustrative only of the principles of the disclosure. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the disclosure to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the disclosure. In this patent document, the word “comprising” is used in its non-limiting sense to mean that items following the word are included, but items not specifically mentioned are not excluded. A reference to an element by the indefinite article “a” does not exclude the possibility that more than one of the element is present, unless the context clearly requires that there be only one of the elements.
