A reciprocating tool employs a motor gear of a drive motor to rotate a drive shaft. When the drive shaft rotates, a sliding member disposed into a ball rolling groove will move along the path of the ball rolling groove. At the same time, for the restriction of annular fixing member, the component force of the sliding member in an axial direction pushes a driven shaft to move back and forth repeatedly along the axial direction, so that a tool fixed on the driven shaft will also back and forth repeatedly in the axial direction, and thus a high efficient reciprocating tool is achieved.

A jigsaw that includes a housing assembly, a shoe member and an indicator. The housing assembly has a housing, a motor and transmission assembly received in the housing, an output member reciprocatingly driven by the motor and transmission assembly, and a trigger coupled to the housing and configured to control operation of the motor and transmission assembly. The housing defines a window. The shoe member is pivotally coupled to the housing. The indicator is pivotally disposed in the housing. A portion of the indicator is visible through the window. Movement of the indicator is responsive to movement of the shoe member such that a rotational position of the indicator is indicative of a position of the shoe member relative to the housing assembly.

A power tool includes a motor housing having a motor configured to rotate an output shaft about a drive axis and a gear housing defining a gear compartment. A pinion gear is supported by the gear housing that is coupled to the output shaft for rotation about the drive axis. A bevel gear is supported by the gear housing for rotation about a bevel axis and includes a geared portion that is meshingly engaged with the pinion gear. A crank pin extends from the same side of the bevel gear as the geared portion at a position offset from the bevel axis. An articulating housing is pivotably supported by the gear housing for pivotal movement about the bevel axis. A plunger member is supported by the articulating housing for reciprocating movement along a reciprocating axis. The plunger member includes a yoke end portion coupled to the crank pin.

A jigsaw generally includes a housing containing a motor activated by a trigger assembly. A single control member is connected to the housing and configured to be accessible by a user. A reciprocating shaft moves at a reciprocation speed and at a magnitude of orbital motion when the trigger assembly is in a retracted condition. The single control member is operable to be positioned among a plurality of positions. Each of the positions corresponds to a predetermined combination of values of the reciprocation speed and the magnitude of the orbital motion.

A cutting tool mechanism and cutting tool (11) including the mechanism (31), for cutting hard material such as concrete and stone is disclosed. The tool (11) has one or two blades (23), (25) each driven by a mechanism (31). Each mechanism (31) has an input coupling 35 for transmission of rotary motion from a motor, and an output coupling (141), (143) to transmit resultant orbital, oscillatory or impact motion to the blade (23), (25). A suspension or sliding coupling located between the output coupling (141), (143) and the blade (23), (25), is provided, through which motion to the blades is transmitted. The suspension or sliding coupling absorbs impacts of the blades with the material being cut, rendering the tool more controllable.

A hand-held power tool includes an SDS tool receiver and a tool housing. The SDS tool receiver includes at least one vacuuming-off channel and is configured to receive an exchangeable insert tool such that the at least one vacuuming-off channel enables removal of dust produced during operation of the exchangeable insert tool with a workpiece. The tool housing includes at least one drive unit configured to drive the exchangeable insert tool.

A Dust Capturing Device for Reciprocating Saws is disclosed. The device is attachable to a convenational shop vacuum cleaner so that virtually all dust created by the reciprocating saw at the cutting blade is captured by the vacuum cleaner. The system is universally attachable to all powered reciprocating saws on the market. A pair of suction hoses are snugly attached to the body of the saw, from intake ports located adjacent to the saw blade to an adapter manifold that combines the two suction hoses into a single hose adaptable to the vacuum cleaner hose. The hoses are attached to the body of the saw by one or more body straps, with each body strap having a pair of hose clips extending therefrom for restraining the two suction hoses running along the body.
