Patent ID: 8037789

Claim:
A drywall anchor installation device, the device comprising: a main driver member having a first end, a second end, a longitudinal axis, a bore, and a central channel extending about its longitudinal axis, the bore traverses the main driver member perpendicular to its longitudinal axis at a position in between the first end of the main driver member and the second end of the main driver member, the central channel has a closed first end and an open second end, the first end of the main driver member is configured to be received by a standard hexagonal driver and the second end of the main driver member is configured to engage a self drilling wall anchor with a Philips head screw top; a plunger member having a first end, a second end, a longitudinal axis, and a notch, the notch extends about the longitudinal axis of the plunger member at a position that is between the first end of the plunger member and the second end of the plunger member, the second end of the plunger member is configured to engage a standard Philips head screw having a head smaller than the head of the self drilling wall anchor engaged by the main driver member, the plunger member is housed in the central channel of the main driver member in such a way that the plunger member can slide about the longitudinal axis of the main driver member to a predetermined extending point; and a plunger guiding mechanism comprising of a compression spring and a guide pin, the compression spring is positioned between the closed first end of the central channel of the main driver member and the first end of the plunger member, the compression spring further biasing the plunger to an extended position such that the plunger extends from the second end of the main driver member to a predetermined extending point for being received in an axial bore of the self drilling drywall anchor, the guide pin is fixedly received by the bore of the main driver member and positioned so that the guide pin is engaged with the notch of the plunger member so that the plunger member is prevented from fully exiting the central channel of the main driver member when extended and when retracted the second end of the plunger forms in combination with the second end of the main driver member a contiguous end configured to engage a Philips head screw top.
