INERTIA IMPACT TOOL Russian patent published in 2007 - IPC B25D11/00 

FIELD: mechanical engineering.

SUBSTANCE: invention relates to means changing modes of operation of tool head. Proposed tool has body, head made for impact movement, electric motor to set tool head in motion, first and second switches and mode change mechanism. Electric motor is made to provide operation when first and second switches are ON. First switch is made to change over from ON position into OFF position and to hold in OFF position. Second switch is made to change over between ON and OFF positions and hold in one of said positions and change over into opposite position. Mode change mechanism is made to provide changing over impact modes of tool head. First impact mode serves to set into action first switch when second switch is locked in ON position. Second impact mode serves to set into action second switch when first switch is locked in ON position.

EFFECT: simplified operation of inertia impact tool.
