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.

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.
