Rotary power tool
First Claim
1. A rotary power tool comprising:
- a tool body, a rotary-disk shaped tool bit having a rotating surface, the tool bit performs a predetermined operation on a workpiece by a rotating movement around a rotating axis that extends perpendicular to the rotating surface, wherein the tool bit is disposed on one tip end region of the tool body such that the rotating axis extends to cross the longitudinal direction of the tool body, a handle coupled to the tool body at the end region of the tool body opposite to the region where the tool bit is mounted, the handle is disposed in a predetermined initial position in which the handle longitudinally extends parallel to the longitudinal direction of the tool body, a pivot region provided between the tool body and the handle, wherein the handle rotates with respect to the tool body around the pivot region in any direction crossing the longitudinal direction of the tool body and an elastic element disposed between the tool body and the handle, the elastic element applying a biasing force to the handle rotated around the pivot region with respect to the tool body such that the elastic element biases the handle to return to the initial position.

Abstract
In order to provide an effective technique in simplifying the vibration-proof structure of a handle equipped in a rotary power tool, a representative rotary power tool 101 is provided with a tool body 103, a rotary-disk shaped tool bit 115, a handle 109, a pivot region 121 and an elastic element 129. The handle 109 coupled to the tool body 103 is disposed in a predetermined initial position in which the handle 109 longitudinally extends parallel to the longitudinal direction of the tool body 103. The handle 109 can rotate with respect to the tool body 103 around the pivot region 121 in any direction crossing the longitudinal direction of the tool body 103. The elastic element 129 is disposed between the tool body 103 and the handle 109 to apply a biasing force to the handle 109 such that the elastic element 129 biases the handle 109 to return to the initial position.
