Motor-driven hand drill, screw driver, etc.

摘要

The hand drill motor (13) has a shaft (12) extending parallel to the working spindle (2), and is positioned below the ergonomically shaped handgrip (6) with switch (7) and switch knob (8). Turning movement of the motor is transmitted to the working spindle, with clamping device (4), via an intermediate shaft (9) with toothed gears (10,11) and bevel gear (3), which is located approximately parallel to the handgrip. Transmission of the motor movement is via a transmission gear block and intermediate gears to the toothed gear of the spindle.
