Abstract

A detachable and adjustable auxiliary handle for a long-handled material-moving tool that includes a swiveling hand grip attached to an outer section of lightweight galvanized tubing, housing an inner section of lightweight galvanized tubing, that is adjustable in length by inserting a push pin through the outer tubing into any one of a plurality of through holes in the inner tubing. The inner tubing has a tube fitting at the bottom to be pivotly attached to a swiveling u-shaped form, connecting the downward directed bolt of the u-shaped form to a coupling nut that is welded to the top of the base of a standard muffler clamp. The base portion of the muffler clamp is then attached with the threaded u-bolt of the muffler clamp and then fastened to the lower end of a long-handled material-moving tool. The swivel action of the hand grip and u-shaped form, along with the adjustable and pivotable tubing, relieves the strain on ones back, wrist, and forearm while shovelling.
