A blade clamp, for use with a power tool having a reciprocating spindle, includes a cover rotatably coupled to the spindle and a detent received within a bore of the spindle. The detent is movable in a radial direction relative to a longitudinal axis of the spindle to adjust the blade clamp between a locked configuration and an unlocked configuration. The cover is rotatable between a first rotational position relative to the spindle coinciding with the locked configuration, and a second rotational position relative to the spindle coinciding with the unlocked configuration. The blade clamp further includes a sleeve in which the detent is slidably received. The sleeve includes a non-corrosive material for inhibiting corrosion of the detent.

A power tool has a clamping mechanism having an assembling mount and two clamping blocks. The assembling mount has a main body, a receiving recess defined in the main body, two first limiting troughs communicating with the receiving recess, and a through hole defined through a bottom of the receiving recess. The two clamping blocks are disposed in the receiving recess. Each one of the two clamping blocks has an abutting face corresponding to the bottom of the receiving recess in shape and facing to the bottom of the receiving recess. One of the two clamping blocks has two limiting ribs respectively inserted in the two first limiting troughs. The two limiting ribs respectively guided and blocked by the two first limiting troughs to prevent the clamping block from sliding downward along the bottom of the receiving recess.

A clamp arrangement for securing an accessory to an oscillating power tool can include a clamp assembly including a first clamp member that moves relative to the accessory between a closed position wherein the clamp assembly retains the accessory and an open position wherein the first clamp is offset from the accessory permitting removal of the first accessory from the clamp assembly. The clamp assembly can further comprise a second clamp member having a first portion that opposes the first clamp member and cooperates with the first clamp member to clamp the accessory between the first and second clamp members. An attachment plate can carry the clamp assembly. The attachment plate can have a first mating detail formed thereon that is configured to selectively and removably mate with a complementary second mating detail on the power tool in an assembled position.

A power tool attachment saw according to the invention is provide and includes a body plate, a connector section and a plurality of cutting walls. The body plate is a planar body and the connector section positioned on one side of the planar body and adapted for attachment to an oscillating power tool. The plurality of cutting walls are positioned orthogonal to and extend from exterior edges of the planar body to form a material receiving space. The plurality of cutting walls provide a uniform cutting edge about the material receiving space.

Several means 71, 72, 73, 74, and 75 are provided for restricting a relative displacement in a separating direction of half-split housings 50L, 50R. At one or more of several screw-connection parts 60 of the left and right half-split housings 50L, 50R, a press-fitting protrusion 71a is provided in an insertion hole 62a of a boss-receiving part 62 into which a screw-boss part 61 is inserted. By press-fitting the screw-boss part 61 to the boss-receiving part 62, a separation resistance may be introduced between the left and right half-split housings 50L, 50R.

A power tool (1), such as a multi-tool, includes: a motor (21) extending in a front-rear direction; a motor housing (2) that houses the motor (21); a head housing (7) held forward of the motor housing (2); and an output shaft (60) protruding downward from the head housing (7). The head housing (7) may be made of a resin. In addition or in the alternative, the head housing (7) includes a lower-head housing case (4) screw fastened to an upper-head housing cover (5). In addition or in the alternative, the motor housing has a two-halved structure in which two half housings (2a, 2b) are screw fastened together.

A blade assembly including a guide bar having a proximal end and a distal end, the guide bar including a bottom bar, an inner bar and an outer bar that are stacked together, the inner bar holding the bottom bar and outer bar in a spaced relation from each other. The blade including a blade base at least partially disposed inside the guide bar and a blade head having a thickness at least equal to a thickness of a distal end of the guide bar, the blade head having teeth. A connecting member that extends internally through the guide bar, the connecting member being connected to, and extending proximally away from, the blade base. The connecting member and the blade are a monolithic, one-piece component.

A sagittal saw assembly including a handpiece and a blade assembly. The blade assembly may comprise a static guide bar, a blade and a drive member, that when actuated, oscillates the blade. The blade may further comprise teeth that extend distally from the static guide bar, the teeth adapted to form a kerf in tissue against which the teeth are pressed. The static guide bar may be dimensioned to fit into the kerf formed in the tissue cut by the teeth. The static guide bar may comprise a thickness dependent on a length of the static guide bar. The blade assembly may be configured such that blade may be the only oscillating component of the blade assembly to provide a generally constant mass moment of inertia irrespective of the mass and/or length of the static guide bar.

A surgical sagittal saw blade cartridge that includes a guide bar formed from an inner layer and opposed outer plates. The inner layer comprising an outer tine extending distally from the proximal end of the guide bar. An outer surface of the outer tine forms a section of a side surface of the guide bar. A side weld may be formed along the side surface of the guide bar. The cartridge may include a blade coupled to the guide bar, the blade comprising a web disposed between the two outer plates. The blade may include a blade head integral with and located distal to the web, the head formed with teeth located distal to the guide bar, the teeth having a sufficient thickness to form a kerf able to receive the guide bar. A method of forming the cartridge is also contemplated, including welding the inner layer to the outer plates.
