Vibration isolation handle

A handle comprising:

• a handle body designed to be selectively mounted to different kinds of power tools,
• a grip coupled to the handle body such that the grip can move with respect to the handle body,
• an elastic element disposed between the grip and the handle body when viewed along a longitudinal axis of the handle, the elastic element applying a biasing force to the grip upon movement of the grip with respect to the handle body, and
• a through hole formed through the grip, the through hole extending in a direction crossing an axial direction of the grip, wherein the elastic element and an elastic outer surface member are connected to each other via a connecting portion that lies in the through hole,
• wherein a natural frequency of the grip can be changed according to the kind of power tool to which the handle is mounted.

A power tool comprising:

• a tool body,
• a main handle and an auxiliary handle to operate the tool body, wherein the auxiliary handle comprising:
• a handle body mounted to the tool body,
• a grip coupled to the handle body such that the grip can move with respect to the handle body and
• an elastic element disposed between the grip and the handle body when viewed along a longitudinal axis of the handle, the elastic element applying a biasing force to the grip upon movement of the grip with respect to the handle body, wherein a natural frequency of the grip can be changed such that the natural frequency of the grip is displaced from a frequency of vibration caused by the power tool when the auxiliary handle is mounted to the tool body, and
• a through hole formed through the grip, the through hole extending in a direction crossing an axial direction of the grip, wherein the elastic element and an elastic outer surface member are connected to each other via a connecting portion that lies in the through hole.
