  • Publication number: 20210331304
    Abstract: A work tool includes a motor, a driving mechanism, a body housing and a handle. The driving mechanism is configured to perform an operation of linearly reciprocating the tool accessory along a driving axis extending in a front-rear direction. The handle includes a grip part extending substantially in an up-down direction, and a battery-mounting part provided on a lower side of the grip part. An upper end portion of the handle is connected to a rear end portion of the body housing via an elastic member so as to be movable relative to the body housing. A lower end portion of the handle is connected to the rear end portion of the body housing so as to be rotatable relative to the body housing, around a rotation axis extending in a left-right direction. The rotation axis is located on a lower side of the battery-mounting part.

  • Patent number: 11084157
    Abstract: A work tool includes a motor, a driving mechanism, a housing, a handle, a detecting mechanism and an elastic support part. The detecting mechanism is configured to detect information corresponding to an operating state of the work tool. The elastic support part supports the detecting mechanism so as to be movable relative to the housing in at least two of a front-rear direction, an up-down direction and a left-right direction. The elastic support part includes at least one elastic member disposed between the detecting mechanism and the housing. The elastic support part has respectively different spring constants in the at least two directions.

  • Publication number: 20200306904
    Abstract: A dust collecting system includes a power tool and a dust collector. The power tool is configured to perform processing operation on a workpiece by driving a tool accessory. The dust collector is configured to collect dust generated by the processing operation. The power tool includes a first motor and a driving mechanism configured to drive the tool accessory by power of the first motor. The dust collector includes a second motor and a fan configured to be rotationally driven by the second motor to generate air flow for collecting dust. The dust collecting system includes a first control device configured to control a rotation speed of the second motor according to a driving state of the power tool.

  • Publication number: 20200306907
    Abstract: A dust collecting system includes a power tool and a stationary dust collector. The power tool is configured to perform processing operation on a workpiece by driving a tool accessory. The stationary dust collector is configured to be placed separately from the power tool and to collect dust generated by the processing operation. The power tool includes a first motor and a driving mechanism configured to drive the tool accessory by power of the first motor. The dust collector includes a second motor and a fan configured to be rotationally driven by the second motor to generate air flow for collecting dust. The dust collecting system includes a control device configured to control a rotation speed of the second motor according to a driving state of the power tool.
