Abstract
A power tool having a hammer mechanism includes a final output shaft configured to removably hold a tool accessory and defining a driving axis of the tool accessory, a housing, and a handle movable relative to the housing in an axial direction of the driving axis. The housing and the handle at least partially have such a shape that a radial distance between the housing and the handle is shorter when the handle is located at a first relative position maximally separated from the housing in the axial direction than when the handle is located at a second relative position close to the housing in the axial direction.
Claims16
A power tool having a hammer mechanism, the power tool comprising:
- a final output shaft configured to removably hold a tool accessory, and defining a driving axis of the tool accessory;
- a motor;
- a driving mechanism configured to perform at least a hammering operation of linearly driving the tool accessory along the driving axis using power of the motor;
- a housing;
- a handle configured to be movable relative to the housing in an axial direction of the driving axis;
- a biasing member configured to bias the handle away from the final output shaft in the axial direction;
- and
- at least one guide member disposed between the housing and the handle so as to extend in the axial direction, and configured to slidably guide relative movement between the handle and the housing,
- wherein the housing and the handle at least partially have such a shape that a radial distance between the housing and the handle is shorter when the handle is located at a first relative position maximally separated from the housing in the axial direction than when the handle is located at a second relative position close to the housing in the axial direction.
