POWER TOOL Russian patent published in 2016 - IPC B25F5/00 B25B23/14 

FIELD: machine building.

SUBSTANCE: invention relates to power tools. Power tool (1) includes motor (3) that is connected to spindle (6), gear mechanism (20) reducing the speed of spindle in tubular gear case (9) that is arranged ahead of motor (3), and tubular bracket (8) mounted on motor (3) to connect motor (3) and the tubular gear case (9) to each other. Tool is equipped with at least one pin (28) that is located in bracket (8) of the motor and in tubular gear case (9) to connect bracket (8) of the motor and tubular gear case (9) to each other. Said at least one pin (28) is engaged with a first-stage internal gear (23A) that is located at a first stage of planetary gear speed reduction mechanism (20) to restain first-stage internal gear (23A) from rotation and retain it in place in its axial direction for lowering the speed of spindle rotation.

EFFECT: technical result consists in simplification of the design of gear case with simultaneous preservation of its rigidity.
