Power driven mfg. and assembly implement

摘要

The implement carries two different retainers located centrally and mutually offset, i.e. a special retainer for screwdriver bits and another one for drills with rapid clamping. The implement body has a corresp. cavity for the retainers at rest. There is a compression rotary shaft in which only one retainer works, or is at rest, when the desired retainer is pressed against the corresp. workpiece, or material.
