PERIMETER DEVICE Russian patent published in 2019 - IPC B25D17/24 B25D11/00 

FIELD: physics.

SUBSTANCE: invention relates to an impact tool. Proposed tool comprises case and striker mechanism. Housing has first housing element and second housing element. Booster mechanism is made on the first element of the housing. First housing element is movable relative to second housing element. First housing element and second housing element are connected via damping mechanism. First element of the housing has a mechanism for reducing vibration. Vibration reduction mechanism comprises a dynamic vibration absorber. Dynamic vibration absorber includes elastic element having the first resilient element located on the side of the first element of the housing, and the second resilient element located on the side of the second element of the housing. Weight is located between first resilient element and second resilient element.

EFFECT: as a result, vibration transmission resulting from impact action is reduced to user.
