Providing a reciprocating tool capable of reducing vibrations generated during operations and improving work performance and processing precision. A reciprocating tool includes a transmission gear part 61 and a counter weight part 62. The transmission gear part 61 includes a bevel gear 611 and a weight 611A. The bevel gear 611 is rotatable in a first direction about an axis B by receiving a drive force of a motor 3. The weight 62A is rotatable in a second direction opposite to the first direction about the axis B by receiving the drive force of the motor 3. A center of gravity 61G of the transmission gear part 61 and a center of gravity 62G of the counter weight part 62 are separated farthest from a blade mounting part 8 when the blade mounting part 8 is positioned in a rearward position. The center of gravity 61G of the transmission gear part 61 and the center of gravity 62G of the counter weight part 62 are closest to the blade mounting part 8 when the blade mounting part 8 is positioned in a forward position.

A reciprocating cutting tool is provided, wherein the tool has a reciprocating saw mode and a jig saw mode. The tool includes a reciprocating mechanism; an actuating mechanism and a cutter-lifting mechanism. The reciprocating mechanism includes a reciprocating rod and the cutter-lifting mechanism includes an actuating member and a pushing member. The actuating member includes a first engaging portion and a second engaging portion when the reciprocating rod is driven to perform a reciprocating motion, the reciprocating rod drives the pushing member to deflect close to the first engaging portion or second engaging portion; when the first engaging portion or the second engaging portion is driven to move close to the pushing member, the first engaging portion or second engaging portion pushes the pushing member towards the side which the first engaging portion or the second engaging portion deflects to force the reciprocating rod to implement a cutter-lifting 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.

There is a hand-held machine tool, in particular a saber saw, with a housing, a drive motor with an output shaft, a spindle for receiving a tool, in particular a saw blade, and a motion converter for converting a rotational motion of the drive shaft into a reciprocating motion of the spindle. The motion converter comprises an eccentric element driven by the output shaft rotationally about an axis of rotation with a driver part arranged eccentrically to the axis of rotation, and a pendulum element which is mounted pivotably about a bearing point and is connected via a coupling point to the spindle. The pendulum element has a guide element for guiding the driver part. In one embodiment, the guide element is arranged between the bearing point and coupling point.

A reciprocating saw includes a housing defining a motor housing portion, and a motor positioned in the motor housing portion, the motor having a motor output shaft defining a rotational axis, and a motor activation switch within the motor housing portion and adjacent the motor. The reciprocating saw also includes a transmission is positioned downstream of the motor and has a sawbar connectable to a saw blade. The transmission converts a rotational input provided by the motor shaft to a reciprocating output of the sawbar along a reciprocating axis that is either coaxial or parallel with the rotational axis.

A reciprocating power tool may include a driving system including a motor and a transmission received in a housing to drive a reciprocating mechanism. A selection mechanism may provide for selection of an operation mode of the reciprocating tool, including a linear mode of operation and at least one orbital mode of operation. Motion of a reciprocating shaft of the reciprocating mechanism may be guided by a guide bracket that is fixed in the housing and an orbit bushing that is movably coupled in the housing. In the linear mode of operation of the tool, the bushing is in a first position relative to the guide bracket. In an orbital mode of operation of the tool, the bushing is moved to a second position relative to the guide bracket.

A front grease retention unit is provided under a front plunger and a wall is provided between the retention unit and a gear accommodation unit. Furthermore, a front grease receiving member is provided under the front plunger and a front metal bearing, and grease falling into the front grease receiving member is sent toward the outer circumferential face of the front plunger. The grease is pushed out by using the vertical oscillation of a front metal anchor bolt in orbital mode. A rear grease receiving member is provided under a rear plunger and a rear metal bearing, and grease falling into the rear grease receiving member is sent toward the outer circumferential face of the rear plunger. The grease in a grease reservoir groove is pushed out by using the vertical oscillation of a rear metal anchor bolt in orbital mode.
