A reciprocating tool includes a motor, a reciprocating member, and a crank mechanism. The motor is disposed in a housing. The reciprocating member projects from the housing. The crank mechanism converts rotation of a rotation shaft of the motor into reciprocation of the reciprocating member. The crank mechanism rotates around an axis in a lateral direction by rotation transmission from the rotation shaft, and the crank mechanism includes a crank member having an eccentric pin, a connecting rod coupling the eccentric pin to the reciprocating member, and a balancer coupled to the eccentric pin, and the balancer is supported by the eccentric pin alone in the housing.

A reciprocating saw includes a housing, a motor positioned within the housing, a drive shaft defining a longitudinal axis, and a spindle positioned substantially within the housing and coupled to a wobble plate. The spindle includes a throughbore formed by a flow welding process, wherein the throughbore extends through the spindle to receive the wobble plate.

A reciprocating tool includes: a motor; a gear case; a converting mechanism; a plunger; a sealing member; and an auxiliary sealing member. The converting mechanism is accommodated in the gear case and configured to convert rotating motion of the motor into reciprocating movement in a predetermined direction. The plunger is provided with a mounting portion on which an end bit is mountable, and is reciprocally movably supported to the gear case. The plunger is driven by the converting mechanism to reciprocally move in the predetermined direction. The plunger is reciprocally movably inserted into the sealing member in the predetermined direction. The sealing member is supported by the gear case. The auxiliary sealing member is supported by the sealing member and sealing an outer peripheral surface of the plunger.

A jigsaw including a housing, a drive assembly disposed within the housing and selectively driven by a power source, an output spindle to which a saw blade is attachable and driven in a reciprocating manner by the drive assembly, a foot plate coupled to the housing and configured to support the housing relative to a workpiece during a cutting operation, and a shoe removably coupled to the foot plate and configured to contact the workpiece during a cutting operation. The shoe includes a blade accommodating region within which at least one replacement saw blade is receivable for storage.

A power tool includes a housing, a rechargeable battery pack coupled to the housing, and a motor supported by the housing. The motor includes a stator assembly having a stator frame with an opening extending therethrough and a plurality of coil windings configured to be selectively powered by the rechargeable battery pack. The coil windings are positioned adjacent the opening of the stator frame. The motor further includes a rotor assembly disposed within the stator assembly and configured to rotate as the coil windings are powered by the rechargeable battery pack. Moreover, the power tool includes an output drive assembly supported by the housing. The output drive assembly extends through the opening of the stator frame to be operably coupled to the rotor assembly.

The present invention relates to a power tool and a method for controlling a stopping position of a cutting element in the power tool, the power tool including a cutting element, a sensor arranged to detect a position of the cutting element, and a controller operably connected with the sensor and the drive mechanism, for controlling a stopping position of the cutting element based on the detection by the sensor. When changing the cutting element, it is desirable to stop the cutting element at a higher position away from the object being cut, ideally the highest position. By utilizing a sensor to detect a sensed object in the cutting element, this method of control is automatic and reliable, allowing the user to change the cutting element easily and efficiently.

A method of manufacturing a spindle for a reciprocating saw includes machining a first portion of the spindle and forming a throughbore extending through the first portion via a flow welding process. The flow welding process includes rotating a rod relative to the spindle and inserting the rod into the first portion of the spindle, thereby displacing material from the spindle in a direction away from the rod to form the throughbore and a collar adjacent the throughbore.

A reciprocating power tool may include a driving system driving a reciprocating mechanism. A selection mechanism provides for selection of a linear mode of operation or at least one orbital mode of operation. Motion of a reciprocating shaft of the reciprocating mechanism may be guided by a guide bracket fixed in the housing and an orbit bushing movably coupled in the housing. The guide bracket may include at least one guide slot having a contoured guide surface that guides the motion of the corresponding end portion of the reciprocating shaft. The contoured guide surface may guide the corresponding end portion of the reciprocating shaft in a corresponding direction relative to the longitudinal centerline of the at least one guide slot during an out stroke and a return stroke of the reciprocating stroke.
