  • Patent number: 10315300
    Abstract: A dust collection device, that collects dust particles generated by an impact tool, has a feature that enables the attachment of the device to the impact tool, which is not provided with an attachment section for the device. The dust collection device has a tool body and an auxiliary handle, attached removably to the tool body, and is attached to an electric hammer that, in the lengthwise direction, linearly operates a tool bit mounted to the tip region of the tool body, and collects dust generated by the electric hammer. The dust collection device has: a dust collection unit that has a dust intake port at the tip; a dust collection hose, connected to the dust collection unit, for transferring dust to the downstream side; and a hose-holding unit that holds the dust collection hose. The hose-holding unit can be attached to and removed from the auxiliary handle.

  • Patent number: 9302363
    Abstract: Disclosed is a feature that collects dust particles that arise from a processing operation of an impact tool. The dust collection device collects dust that arises from of a processing operation and is attached to the impact tool that performs a pre-determined processing operation on a processed member by way of a tool bit mounted to the tip region of the tool body being linearly operated at least in the lengthwise direction. The dust collection device has a dust collection unit of which the tip opens as a dust intake port and the contour shape is formed unevenly around the long axis of the tool bit. The position of the dust collection unit is freely selected around the long axis of the tool bit, and it is possible to cause the position to change around the long axis of the bit.

  • Publication number: 20130161049
    Abstract: A feature that contributes to an improvement in the attachment to an impact tool of a dust collection device that is attached to the impact tool and that collects dust particles that said impact tool generates. The dust collection device collects dust that the impact tool generates and is attached to said impact tool that, in the lengthwise direction, linearly operates a tool bit that is mounted to the tip region of a tool body. The dust collection device has: a dust collection unit that has a dust intake port at the tip; and a dust transfer unit that is connected with the dust collection unit in order to transfer dust sucked in from the dust intake port towards the downstream side. The dust collection unit is held by the shaft section of the tool bit, and the dust transfer unit is held by the tool body.
