摘要： A reciprocating saw 11 with a keyless blade clamp 35 having a slotted-channel 37 in a clamp body 39 for receiving a blade 40 alternatively in first and second, intersecting cutting planes. The blade 40 may be alternatively oriented in four 90° offset orientations with the blade teeth facing in the same directions as the top, bottom, left and right side of the saw 11. When the retainer 53 is in the clamp disengaged position, a blade 40 may be slidably inserted and removed from the channel 37 in any of the four 90° offset orientations. A retainer 53 is located in a track 51 in the clamp body 39 and is movable between clamp engaged and disengaged positions. When the blade 40 is located in the first cutting plane, the retainer 53 engages the edge 55 of the blade. When the blade 40 is in the second cutting plane, the retainer 53 engages the sidewall 57 of the blade 40. A manual operated, spring biased release 61 is pivotally connected to the clamp body 39 and is connected to the outer tips 73, 75 of the retainer 53 for moving the retainer 53 between a clamp engaged and a clamp disengaged position.

摘要： A reciprocating tool (e.g., a reciprocating saw) comprising a housing, a spindle mounted for reciprocating movement within the housing and having an end adapted to receive a saw blade, and a blade clamp mechanism connected to the spindle and adapted to attach a saw blade to the spindle. The blade clamp mechanism includes an actuating member mounted on the end of the spindle and capable of moving relative to the spindle between an engaged position and a disengaged position, and a locking member operatively associated with the actuating member and moveable relative to the spindle between a locked position that locks a saw blade to the spindle and an unlocked position that releases the saw blade. Movement of the actuating member from the disengaged position to the engaged position results in forced movement of the locking member from the unlocked position to the locked position, and movement of the actuating member from the engaged position to the disengaged position results in forced movement of the locking member from the locked position to the unlocked position.

摘要： A reciprocating saw. The saw including a housing, a spindle supported for reciprocation relative to the housing, the spindle having an end selectively supporting a saw blade, a motor for moving the end during a cutting stroke and a return stroke, and path defining structure interconnected with the spindle and defining a first path of travel of the end relative to the housing during a first cutting stroke and during a first return stroke and a second path of travel of the end relative to the housing during a second cutting stroke and during a second return stroke, the second path of travel being different than the first path of travel. The saw blade is selectively supported in a first orientation relative to the spindle to have a first cutting direction and in a second orientation relative to the spindle to have a second cutting direction opposite the first cutting direction. The first path of travel is characterized by movement at least partially in the first cutting direction during the first cutting stroke. The path defining structure defines a third path of travel of the end relative to the housing, the end moving along the third path of travel during a third cutting stroke, the third path of travel being characterized by movement at least partially in the second cutting direction during the third cutting stroke.

摘要： A blade is inserted into a slit which extends in an axial direction of a plunger. A bore extends in a direction normal to the axial direction of the plunger and merges with the slit. A locking pin is slidably disposed in the bore. A blade holder is coupled around the plunger and slidable in the axial direction of the plunger. The blade holder shifts in an axially forward direction to generate a pushing force applied to the locking pin. The locking pin engages with a hole of the blade. Furthermore, the blade holder shifts in an axially rearward direction to release the pushing force applied to the locking pin. The locking pin disengages from the hole of the blade.

摘要： A vent cover for an electric saw for removing waste sawdust, dust or debris from a work area so as to maintain a guideline free from visual obstruction including a shell having an opening at its back end and one side being opened so that the shell may be detachably connected to the side of the saw body immediately ahead of the motor armature discharge baffling. The front end of the shell is curved and the top of the shell is tapered forwardly so that the exhaust air enters the rear of the shell and is directed by the curvature of the tapered top and curved front end to be conducted laterally across the front of the saw blade to forcibly remove sawdust. The shell includes an edge marginal region along the top front end and bottom for detachably coupling to the side of the saw body.

摘要： The present disclosure relates to a jig saw blade clamp including a first clamp member defining a main slot. A second clamp member is positioned within the main slot. The first clamp member is moveable relative to the first clamp member between a first position in which the first and second clamp members are adapted to clamp a blade, and a second position in which the blade can be inserted between the first and second clamp members. A collar is pivotally moveable in first and second opposite directions relative to the first and second clamp members. The collar includes a cam portion that moves the second clamp member toward the first position when the collar is pivoted in the first direction, and also moves the second clamp member toward the second position when the collar is pivoted in the second direction.
