Abstract

Improvements in the construction of simple mandrels for motor tools, preferably for simple electric drills by hand, which have a chuck body screwed onto the spindle of the drill by hand, joined with a bushing having a conical inner surface, in which several jaws are guided, constructed as frustoconical pieces, each provided with a clamping surface, separated from each other by springs, characterized in that two jaws are provided which are guided by means of a slot guide and key in the conical inner surface of the jaw. Cap, and that settle with its front surface facing the motor drive tool, directly against the front side of the spindle of the motor tool.
