Auxiliary handle attachment for a material-moving tool

An adjustable, auxiliary handle accessory, adapted for attachment to material-moving tool, for reducing stress on the tool user said handle accessory comprising, in combination:

• (a) a removable clamping device, adapted to clamp tightly around a cylindrical shaft handle portion of the tool, said clamping device including two substantially identical clamshell members hinged together at one end and having mating semi-circular sections designed to surround the shaft portion and clamp tightly together around the shaft portion for fixed attachment thereto, said clamshell members each having a hemispherical indentation at an opposite end thereof that form a hollow sphere when said clamshell members are held together in the clamped position, said clamping device further including releasable locking means for holding the two clamshell members tightly together in the clamped position and for releasing the clamshell members for removal from, or repositioning on, the tool;
• (b) a removable handle device having a spherical knob at one end designed to fit snugly inside the hollow sphere when the clamshell members are clamped tightly together around the shaft portion of the tool and having a gripping member at an opposite end designed to be conveniently gripped by a user;
• wherein the hollow sphere formed by the clamshell members includes a groove, and the spherical knob of the removable handle device has an extending stud, designed to fit in the groove, said groove and said extending stud cooperating to limit the freedom of movement of the handle device and thereby enable the user to control the tool by applying forces in desired directions.
