| 摘要 | A three-part auxiliary shaft assembly (20) to be mounted along a hand-tool shaft, comprises a two part sleeve (24) and an auxiliary shaft (22) which is a ball-shaped at one end. The sleeve has a top, a bottom and a symmetrical axis running from top to bottom, and is cut in half along the symmetrical axis to define the two parts of the two-part sleeve. Each part has an inner hemi-housing parallel to the symmetrical axis of the sleeve, and running from the top to the bottom of the sleeve for tight-fitting half the cross section of a portion of a hand-tool shaft. Near the top away from the inner hemi-housing, a second inner hemi-housing for half the ball-shaped end of the auxiliary shaft has an opening at the top, shorter than the diameter of the ball-shaped end (22a) of the auxiliary shaft. When the two parts of the sleeve are assembled, a housing is provided for the ball-shaped end of the auxiliary shaft, as well as a housing for the portion of a hand-tool shaft. These two parts are held with bolts positioned away from the opening at the top, so that over a certain pulling tension of the auxiliary shaft, it is releasable from its housing. | ||||||
