    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 blade extension for a reciprocating saw comprises a movable member and a stationary member. The movable member has a proximal end, a distal end and a body extending between the proximal end and the distal end. The proximal end comprises a blade end shaped to be received in a blade holder of the reciprocating saw. The distal end is configured to be coupled to a reciprocating saw blade. The stationary member extends along at least a portion of the movable member and supports the movable member for movement relative to the stationary member. The stationary member has a proximal end configured to be coupled to the reciprocating saw and an opposite distal end. The distal end of the movable member is arranged to protrude distally beyond the distal end of the stationary member.

    摘要： A saw system capable of cutting through a workpiece in one stroke is provided. The saw system includes a base, a turntable mounted on the base for rotation about a vertical axis, a support structure defining a cutting axis and fixedly attached to the turntable, and an elongated blade including a cutting edge. The turntable has a substantially planar support surface for supporting a workpiece. The support structure includes a pair of parallel sliding members, wherein the sliding members are disposed in a direction substantially parallel to the cutting axis. The elongated blade is spaced apart from the sliding members and is movable along the sliding members. The cutting edge includes a proximal end and a distal end, wherein an angle between an imaginary line connecting the distal end of the cutting edge to the proximal end thereof and its projection onto the turntable is an acute angle.

    摘要： A percussive therapy device that includes a housing, an electrical source, a motor positioned in the housing, a switch for activating the motor, and a push rod assembly operatively connected to the motor and configured to reciprocate in response to activation of the motor. The housing includes first, second and third handle portions and a head portion that cooperate to define a handle opening. The first handle portion defines a first axis, the second handle portion defines a second axis and the third handle portion defines a third axis and the first, second and third axes cooperate to form a triangle. The motor is positioned in the head portion of the housing, and at least a portion of the push rod assembly extends outside of the head portion.

    摘要： A method of using a reciprocating saw blade having an elongated body with a front body portion and a rear body portion, each having a front end, a rear end, an elongated cutting edge extending between the front and rear ends and a back edge opposite the cutting edge. A first tang that extends from the rear end of the rear body portion may be coupled to a reciprocating saw. The saw blade may be removed from reciprocating saw, and a second tang, which extends from the rear end of the front body portion, may be exposed by breaking off an entirety of the rear body portion in a single integral piece from the front body portion. The front body portion, without the rear body portion, may be coupled to the reciprocating saw by coupling the exposed second tang to the reciprocating saw.

    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： A pneumatic device includes a cylinder, a buffer member and a piston unit. The cylinder includes a cylinder wall defining an air chamber. The buffer member has a tubular wall that defines a communicating hole. The tubular wall has a length greater than the wall thickness thereof. The piston unit includes a sealing member, and a rod member movably extending through the communicating hole. The rod member has a driven section received within the air chamber and mounted with the sealing member. The piston unit is movable between a restoring position where the driven section is spaced apart from the buffer member, and an impact position where at least one of the driven section and the sealing member is in contact with the buffer member.
