Vibration dampening technology for an impact tool

摘要

Impact tool (100) that performs a predetermined operation by driving a tool accessory (119) in at least one axial direction of the tool accessory (119), with a drive mechanism (120) that drives the tool accessory (119), a motor (110) that drives the Drive mechanism (120) drives a tool body (101) which houses the drive mechanism (120) and the motor (110), a handle (300A), and a power supply cable (309) installed on the handle (300A) and for feeding of power is provided to the motor (110) in which the handle (300A) has a handle body (300) mounted to the tool body (101) and a pair of handles (350) extending in a direction that crosses the axial direction of the tool accessory (119), extends, and is designed to be held by a right and left hand user, the handle body (300) has a first part (301) to which the pair of handles (350) are attached and a second part (303) which is attached to the tool body (101) and to which the first part (301) is connected so that it is movable with respect to the second part (303), the first part (301) is connected to the tool body (101) via an elastic member (339) and can move with respect to the tool body (101) and the second part (303) while it is pretensioned by a spring force of the elastic member (339) and the power supply cable (309) is installed on the second part (303) of the handle body (300).
