Abstract

A tool for loosening or tightening screws. The tool has a number of shafts with screwdriver bits on their ends that are stored in elongated grooves that are parallel to the longitudial axis and circumferentally spaced around the handle. Each stored blade can be rotated separately out of the storage handle 180 degrees on a pivoting hinge into a housing head which locks the extended shafts in place for operation. The housing head can be rotated 360 degrees perpendicular to the elongated axis of the handle in order to accomadate each blade separately.

Claims

1. A hand tool for fastening screws or bolts wherein said hand tool comprising:

A storage handle with an assortment of tool blades spaced in a circumference and longitudinal to the axis of each on the said storage handle, each said tool blades are attached at one longitudinal end of the said storage handle, allowing for the pivoting of said tool blade 180 degrees to the longitudinal axis of the said storage handle, the other end of the longitudinal axis of the tool blade is specifically designed to interact with different screw or bolt heads, at the said longitudinal end of the said storage handle of the attached end of the said tool blades is a fixed housing device, said housing device can rotate perpendicular to the said longitudinal axis of the said storage handle when unlocked, said housing device can align with each said tool blade individually, when said housing device is aligned with a selected said tool blade said tool blade can be pivoted 180 degrees out of the said storage handle, when said tool blade is seated in said housing device said tool blade is ridgedly fixed and is able to withstand rotating torque when fastening or unfastening said screws or bolts.

2. A hand tool for fastening or unfastening screws or bolts according to claim 1 wherein said tool blades are in grooves spaced in a circumference longitudinal to the axis of the said storage handle.

3. A hand tool for fastening or unfastening screws or bolts according to claim 1 wherein said tool blades are attached to the said storage handle by a hinge allowing for pivoting of the said tool blade 180 degrees longitudinal to the axis of the said storage handle allowing the said tool blade to be placed in an operative position in the said housing device.

4. A hand tool for fastening or unfastening screws or bolts according to claim 1 wherein said housing device has an attached rod which extends into the said storage handle, said rod is centrally located and parallel to the said storage handle longitudinal axis.

5. A hand tool for fastening or unfastening screws or bolts according to claim 4 wherein said rod slides in and out of the said storage handle and is held in tension by a spring on the said rod inside the hollow cavity of the said storage handle.

6. A hand tool for fastening or unfastening screws or bolts according to claim 5 wherein said housing device has locking teeth which interacts with locking teeth on the said storage handle when said rod is held in tension by said spring.

7. A hand tool for fastening or unfastening screws or bolts according to claim 4 wherein by pulling said housing device away from and parallel to the said storage handles longitudinal axis where by unlocking the said housing device allowing rotation of said housing device 360 degrees perpendicular to the longitudinal axis of the said storage handle.

8. A hand tool for fastening or unfastening screws or bolts according to claim 7 wherein selection of a said tool blade by alignment with a groove in the said housing device whereas creating a passageway for a said tool blade allowing for rotation into a said operative position.

9. A hand tool for fastening or unfastening a screw or bolt according to claim 8 wherein said housing device contains a locking device which holds the said tool blades in place when in an operative position.

10. A hand tool for fastening or unfastening screws or bolts according to claim 8 wherein said housing device has a flaring which extends over unselected said tool blades pivot point, preventing removal of said tool blades from said storage handle until alignment of said housing device groove with selected said tool blade creating a said passageway.
