DRIVE TOOL Russian patent published in 2014 - IPC B25D17/24 B25D17/08 B25D16/00 B25D11/04 

FIELD: process engineering.

SUBSTANCE: invention relates to hand tool. Proposed tool comprises body, tool holder, flexible element, motor, impact element, mid element and second flexible element. Tool holder can turn about turn point located at axis x defined by tool axis in direction of axes y and x. Flexible element applies thrusting force to tool holder to retain holder at position whereat tool holder and body lengthwise axes are aligned. Mid element is arranged inside tool holder to displace axially of inserted impact tool and to transfer rectilinear motion of impact element to inserted impact tool. Mid element is attached to said body to turn about said turn point located at axis z. Second flexible element is arranged between said body and mid element to apply thrusting force so that mid element is retained at initial position.

EFFECT: decreased vibration.
