The blocking ring has a ventilating portion (a V-shaped slit) that ensures the flow of air to the suction head regardless of whether the elastic deformation has occurred. | 03-07-2013 |
20130055527 | POWER TOOL DUST COLLECTING DEVICE AND POWER TOOL - A power tool dust collecting device includes, in a housing in which a suction opening is protrudingly provided and on which a power tool is mountable, a motor chamber holding a motor having a brush that comes into sliding contact with a commutator of a rotor rotating integrally with an output shaft, a fan chamber housing a dust collecting fan attached to the output shaft of the motor, and a dust collecting chamber in which a filter, through which passes air sucked up from the suction opening due to rotation of the dust collecting fan in accordance with driving of the motor and which collects dust in the air, is mounted on an upstream side of the fan chamber. A cushioning member is interposed between an inner wall of the motor chamber and an outer peripheral surface of the motor. | 03-07-2013 |
20140174871 | HAMMER DRILL - In a hammer drill, a coil spring that urges a first clutch and a second clutch in directions away from each other is held between a first change plate that engages with the first clutch to be slidable in the axial direction of an intermediate shaft and a second change plate that engages with the second clutch to be slidable in the axial direction of the intermediate shaft. The first change plate is slidably guided by a gear housing. | 06-26-2014 |
20140352114 | AUXILIARY HANDLE AND RECIPROCATING POWER TOOL HAVING THE SAME - An effective technique for increasing performance of an auxiliary handle which is attached to a power tool is provided. The auxiliary handle has a grip part, a grip holding part, a mounting part and a support part. The grip holding part is disposed between the grip part and the support part in a longitudinal direction of the auxiliary handle. When the auxiliary handle is attached to a power tool body, the grip part and the grip holding part are held so as to be movable with respect to the mounting part with the support part as a fulcrum. | 12-04-2014 |
20140352994 | RECIPROCATING POWER TOOL - Reciprocating power tool is provided which is improved in vibration isolation of the handle. The reciprocating power tool has a tool body and a handle connected to the tool body. When an axial direction of a tool bit is defined as a longitudinal direction, the handle extends in a vertical direction crossing the longitudinal direction. Further, an upper region of the handle is connected to the tool body via an elastic member and a lower region of the handle is connected to the tool body via a support shaft that it can rotate around an axis of the support shaft in a transverse direction crossing both the longitudinal direction and the vertical direction with respect to the tool body. When the handle rotates around the support shaft with respect to the tool body, the elastic member reduces vibration which is caused in the tool body and transmitted to the handle. | 12-04-2014 |
