Retractable Rotary Tool With Simplified Latch

Abstract

Retractable rotary tool part of robot hand. Similar to one described in "Retractable Rotary-Bit Tool" (GSC-13358), except it includes simpler mechanism for retention in, and release from, retracted position. Conical head at upper end of tool bit latched in retracted position by catch springs. Eccentric neck just below head makes possible to release head from catch springs by rotating telescoping tubular sections and tool bit.
