摘要： A drain clearing air gun includes a housing defining a main body, a handle positioned on a first end of the main body, and a nose positioned on a second end of the main body. A tank is at least partially positioned within the housing and includes a chamber for receiving pressurized air. A motor is positioned within a main body of the housing, and a pump is positioned within the main body of the housing and operatively coupled to the motor. The pump is driven by the motor to pump air into the tank. A pressure gauge is supported by the housing and includes an automatic shutoff feature. The pressure gauge is in fluid communication with the tank. When a predetermined pressure within the tank is reached the automatic shutoff feature is activated to stop the motor.

摘要： A reciprocating saw includes a housing, a motor, and a drive mechanism. The motor is configured to operate in a forward mode corresponding to a first rotational direction, and in a reverse mode corresponding to a second rotational direction opposite the first rotational direction. The drive mechanism includes a driven gear, a connecting rod, an output shaft, and a counterweight. The driven gear is rotated by the motor and has an upper portion and a lower portion. The output shaft reciprocates through a cutting stroke and a return stroke. The counterweight is coupled to the driven gear and rotating with the driven gear. When the motor is operated in the forward mode, the counterweight moves through the upper portion of the driven gear during the cutting stroke of the output shaft, and moves through the lower portion of the driven gear during a return stroke of the output shaft.

摘要： A tool support includes a frame that is configured to support a tool and a powered track supported on the frame. The powered track includes a drive roller, an idler roller, and an endless belt that extends around the drive roller and the idler roller. The tool support also includes a first motor supported on the frame. The first motor is operable to drive the drive roller and rotate the endless belt. The tool support further includes a second motor supported by the frame. The second motor is configured to be coupled to the tool to drive the tool supported on the frame.

摘要： A power tool includes a housing, a motor, and a drive mechanism. The drive mechanism includes a driven gear that is rotated by the motor. The driven gear is vertically-oriented within the housing and has an upper portion and a lower portion. The drive mechanism also includes a connecting rod coupled to the driven gear to translate rotary motion of the driven gear into reciprocating motion, and an output shaft coupled to the connecting rod to reciprocate relative to the housing through a cutting stroke and a return stroke. The drive mechanism further includes a counterweight coupled to the driven gear for rotation with the driven gear. The counterweight moves through the upper portion of the driven gear during the cutting stroke of the output shaft, and moves through the lower portion of the driven gear during a return stroke of the output shaft.

摘要： An expansion tool includes a housing, a motor supported within the housing, a mandrel, and a drive mechanism configured to convert a rotational input from the motor into translational movement of the mandrel. The drive mechanism includes a cam and a drive shaft coupled to the cam. The expansion tool further includes a frame including a hub and a neck extending from the hub and having an opening. A working element is coupled to the neck and has a plurality of jaws movable from a closed position toward an expanded position in response to movement of the mandrel from a retracted position toward an extended position. The mandrel extends through the opening to engage the jaws, and the drive shaft is rotatably supported by the hub.

摘要： A drain cleaning device includes a drum, and a cable positioned within the drum. The cable is operable to be extended out of the drum and into a conduit. The drain cleaning device also includes a motor coupled to the drum to rotate the drum, a sensor operable to detect a characteristic of the cable, and a controller coupled to the sensor and the motor. The controller is configured to receive a signal from the sensor indicative of the characteristic of the cable and send an instruction to the motor to change an operating parameter of the motor based on the signal received from the sensor.

摘要： A reciprocating saw includes a housing, a motor, and a drive mechanism. The drive mechanism includes a driven gear that is rotated by the motor. The driven gear is vertically-oriented within the housing. The drive mechanism also includes a drive arm coupled to the driven gear to translate rotary motion of the driven gear into reciprocating motion, and an output shaft coupled to the drive arm to reciprocate relative to the housing along a spindle axis through a cutting stroke and a return stroke. The drive mechanism further includes a counterweight coupled to the driven gear and rotating with the driven gear through a path and in a same direction. As the counterweight moves through a rearward half of the path, the counterweight generally moves in an upward direction, and as the counterweight moves through a forward half of the path, the counterweight generally moves in a downward direction.

摘要： A hand-held band saw has a housing having an opening defining a cut zone. A first wheel and a second wheel are supported by the housing. The first and second wheels define a blade support portion configured to support a continuous blade to be driven through the cut zone. A handle extends from the housing, the handle having a grip portion. A blade guard is coupled to the housing and configured to move between open and closed positions with respect to the housing. The blade guard is configured to cover the blade support portion in the closed position. A chip vent is configured to provide an outlet for workpiece debris formed during a cutting operation, and a tire brush is configured to engage at least one of the first or second wheels to remove workpiece debris from the at least one of the first or second wheels.

摘要： An expansion tool includes a housing and an expansion head coupled to the housing. The expansion head includes a casing and a plurality of jaws extending from the casing. The plurality of jaws is movable between a closed position and an expanded position relative to a longitudinal axis. Each jaw of the plurality of jaws includes a first sizing portion extending parallel to the longitudinal axis and a second sizing portion extending parallel to the longitudinal axis. The first sizing portions of the plurality of jaws collectively define a first diameter when the plurality of jaws is in the closed position, the second sizing portions of the plurality of jaws collectively define a second diameter when the plurality of jaws is in the closed position, and the second diameter is greater than the first diameter.
