Abstract
A manually powered rotary tool includes improvements to size, drive direction input, drive speed, assembly, strength, and cost. A handle is mounted high in the housing to provide a vertically compact tool. A selector switch controls a spiral ratchet mechanism from outside the housing to better enclose the mechanism and provide improved access to the selecting operation. The ratchet mechanism uses a lateral moving selector bar for effective operation with the external selector switch. The spiral ratchet gears are configured for die cast manufacturing. Various components are of one-piece construction and designed for simplified assembly.
