摘要： A reciprocating shaft assembly in a reciprocating saw moves in a reciprocal motion and drives a saw blade via a blade holder. At least one bore is formed in an end of the reciprocating shaft assembly opposite the blade holder. A pin fixed to the saw passes through the bore and acts as a bearing to support the reciprocating shaft assembly in its reciprocating motion.

摘要： A jig saw for more precise movement during cutting with a laser alignment system for projecting a marker onto a workpiece to align with a target line to be cut. The laser alignment system comprises a housing, a laser generator within the housing, an internal battery supplying the laser generator, a switch which is positioned within the housing and independent of the main switch to turn on and turn off the laser generator. By turning on the switch, the laser generator projects a laser beam onto the workpiece ahead of the blade in alignment with the plane of the blade. The operator only needs to align the projected laser line along a target line on the workpiece to attain the more precise cutting without concentrating his observation exactly ahead of the cutting blade.

摘要： The present invention relates to a reciprocating saw tool (10) having a motor drive (17) with a reciprocating driver (21) for a tool (15) and having a mass equilibrating body (22). In addition, a device (20) is provided, which serves to convert a rotary movement of the motor drive (17) into a reciprocating movement of the reciprocating driver (21) along a first movement axis (41) and an opposite reciprocating movement of the mass equilibrating body (22) along a second movement axis (42). For improving the sawing performance, the mass equilibrating body (22) is guided at an angle α to the reciprocating driver (21) so that its movement axis (42) is constantly at an angle to the movement axis (41) of the reciprocating driver (21).

摘要： A saw blade, for a power saw having two such blades arranged adjacent and parallel to each other and reciprocating in opposite directions, comprises an elongate blade member having teeth along a bottom edge. The teeth comprise at least three types, a first type being at an outer surface of the blade member, a third type being at the inner surface, and the second type being therebetween. The first type are shaped to produce on the blade's bottom edge an outward force away from the inner surface while cutting a workpiece, and the second and third types are shaped to produce on the blade's bottom edge an inward force, the resultant force on the teeth while cutting urging the teeth in an inward direction away from the outer surface towards the inner surface. When the power saw is operating with a pair of these blades, the blades are urged together at their teeth by the cutting action so effectively eliminating penetration of sawdust and cuttings between the pair of blades. Advantageously the saw blades can be very thin-walled, e.g. 1mm to 2mm thick.
