摘要： A right-angle accessory saw for use with an electric drill comprises a drive shaft housing and a saw head. A drive shaft is mounted for rotation within the drive shaft housing. The drive shaft has a drill connection end extending outwardly from a proximate end of the drive shaft housing. The other end of the drive shaft extends through the housing to a cam, located with a distal end of the drive shaft housing. The saw head extends transversely from the distal end of the drive shaft housing. A push rod is mounted for reciprocating translation within the saw head. The push rod includes a cam follower on an inner end and a saw blade holder on an outer end. The push rod is spring-biased inwardly toward the cam. A saw blade is detachably mounted within the saw blade holder.

摘要： An electric-powered cutting machine includes: an electric motor, a housing for the electric motor; a plunger driven by the electric motor to reciprocate; and a blade holding mechanism. The blade holding mechanism holds a blade at a tip end portion of the plunger. The blade holding mechanism includes: a blade receiving face including a groove, a swinging member and a pressing member. The groove is shaped substantially the same as an attachment portion of the blade. The swinging member has one and other ends and pivoted at a swing fulcrum. The one end has a blade pressing portion capable of being disposed to oppose to the groove. The other end elongates to separate from the plunger. The pressing member presses the one end toward the groove.

摘要： A jig saw for more precise movement during cutting with a laser alignment system for projecting a maker 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. Turn 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： A reciprocating saw generally includes a housing and a motor supported by the housing. A spindle is mounted for reciprocation relative to the housing, the spindle having a front end for supporting a saw blade and being movable through a cutting stroke and a return stroke, and the cutting stroke may have a stroke length. A rotary member may be supported for rotation about a rotary axis. The saw may further include an adjusting assembly operable to adjust the stroke length of the spindle. Also, the saw may include a counterweight supported for movement relative to the housing, a movement of the counterweight substantially balancing at least a portion of movement of the spindle, and an adjusting assembly operable to adjust the movement of the counterweight.

摘要： An extension is attachable to the driving shaft of a reciprocating blade tool such as a saber saw. The extension is attached to the drive shaft and the blade is attached to the end of the extension. The extension places the blade at a position spaced laterally and longitudinally from the nominal point of attachment of the blade to the driving shaft, the lateral spacing placing the new blade position approximately at the lateral outside edge of the tool housing, thereby permitting flush cuts. The extension can be formed of an integral strip or sheet having a proximal leg, an intermediate section and a distal leg, joined at equal and opposite obtuse angles. The angles are reinforced by two or more webs bent from the plane of the legs and attached, for example by welding, to the intermediate section.
