Abstract
An impact tool includes a motor, a first hammer, an anvil, and a second hammer. The first hammer is configured to be rotated by driving of the motor. The anvil is configured to be hammered in a rotation direction by the first hammer. The second hammer is configured to be switchable between a state being linked and a state not being linked to the first hammer. The impact tool ensures selections of a first hammering mode in which only the first hammer hammers the anvil and a second hammering mode in which the first hammer and the second hammer hammer the anvil.
Claims10
An impact tool comprising:
- a motor;
- a first hammer configured to be rotated by driving of the motor;
- an anvil configured to be hammered in a rotation direction by the first hammer;
- and
- a second hammer configured to be switchable between a state being linked and a state not being linked to the first hammer, wherein
- the impact tool ensures selections of a first hammering mode in which only the first hammer hammers the anvil and a second hammering mode in which the first hammer and the second hammer hammer the anvil.
An impact tool comprising:
- a motor;
- a spindle configured to be rotated by driving of the motor;
- a hammer retained by the spindle;
- an anvil configured to be hammered in a rotation direction by the hammer;
- an inertia force increasing member that increases inertia force in the hammering by the hammer;
- a housing that houses the motor, the spindle, the hammer, and the anvil;
- and
- a mode switching member disposed in the housing, wherein
- operating the mode switching member ensures selections of a first position in which the hammer hammers the anvil, a second position in which the hammer whose inertia force is increased by the inertia force increasing member hammers the anvil, and a third position in which the spindle, the hammer, and the anvil integrally rotate.
An impact tool comprising:
- a motor;
- and
- a hammer configured to be rotated by driving of the motor, wherein
- changing a mass of the hammer ensures changing an inertia force by a rotation of the hammer, and changing a rotational speed of the motor ensures changing the inertia force.
