Abstract

An apparatus for an improved hand tool device wherein a rotatable apparatus may rotate the rotating handle apparatus in 15 degree increments to adjust to the user to help reduce the risk of injury and increase power application while gardening by adjusting and creating a favorable angle between the ground and the point of entry of the hand tool device into the ground.

Claims (8)

1. A garden tool apparatus comprising: a rod having a first end and a second end; a shovel connected to said first end of said rod; a rotating handle apparatus connected to said second end of said rod; wherein said rotating hand apparatus is comprised of:

a) a hand gripping apparatus comprising a shaft extending between two arms of a yoke and a lower cylindrical body having a hollow portion and a outer perimeter wherein said lower cylindrical body further comprises threads along said outer perimeter;

b) a rotatable apparatus having a cylindrical outer body with a lower rib along the perimeter of said cylindrical outer body and an inner hollow body wherein said hollow body is attached to said second end of said rod;

c) said rotatable apparatus is further connected to said hollow portion of said hand gripping apparatus, whereby said hollow portion is freely rotational against said rotatable apparatus, and wherein said hand gripping apparatus rotates along the linear axis of said rod;

d) said rotatable apparatus is further comprised an impediment device wherein said impediment device impedes rotation of said hand gripping apparatus against said rotatable apparatus wherein said impediment device is disabled by applying acute rotation force onto said hand gripping apparatus;

e) wherein said impeding device is comprised of a plurality of circular sink holes radially positioned along the circumference of a surface within said hollow portion of said hand gripping apparatus;

f) a plurality of recesses positioned on a surface of said rotatable apparatus wherein each of said plurality of recess houses a metal spring and a stopper wherein said stopper is further inserted into one of said plurality of sink holes when said housing connector is connected to said hollow portion of said hand gripping apparatus thereby impeding the rotation of said hand gripping apparatus against said rotatable apparatus unless acute rotational force is applied onto said hand gripping apparatus;

g) a cylindrical sleeve encircling said rod and said rotatable apparatus, and wherein said sleeve comprising internal threads and wherein said sleeve secures said rod and said connector housing into said hollow portion of said hand gripping apparatus by engaging said threads inside said sleeve to said threads along said outer perimeter of said and gripping apparatus.
