A reciprocating saw comprises a housing, a blade assembly, a reciprocating rod assembly, a driving assembly and an operation mechanism. The blade assembly extends forward from one side of the housing, and comprises a positioning structure. The reciprocating rod assembly is detachably connected with the blade assembly and comprises a blade fixing structure and an unlocking component matched with the positioning structures. The driving assembly is accommodated in the housing, and drives the reciprocating rod assembly to drive the blade assembly to perform reciprocating motion. The operation mechanism is installed on the housing and moves between a locking position and an unlocking position and comprises an operation button, a drive cam matched with the unlocking components and an elastic reset component for resetting the operation button.

A percussive massage device that includes a housing, an electrical source, a motor positioned in the housing, a switch for activating the motor, a push rod assembly operatively connected to the motor and configured to reciprocate in response to activation of the motor, a massage attachment configured to be removably attached to the push rod, and an attachment module operatively connected to the housing. The housing includes first, second, and third handle portions that cooperate to define a handle opening, wherein 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 wherein the first, second, and third axes cooperate to form a triangle.

A twist grip throttle assembly and weed trimmer utilizing the same are described herein. The weed trimmer has a power head on an upper end of a drive shaft assembly. The power head has a power provider, such as a gas powered motor. A base assembly with a cutter head for receiving wrapped cord is on a lower end of the drive shaft assembly. A throttle activator includes a tubular member rotationally mounted on the drive shaft assembly. The tubular member defines a gripping area. Twisting rotation of the throttle activator adjusts an amount of power produced by said power provider.

An accessory for an oscillating power tool includes an anchor for selectively coupling with an oscillating power tool. The anchor includes a generally planar portion having an anchor interface configured to couple to the oscillating power tool and defining a longitudinal axis and a center point. The anchor interface includes a central aperture and a plurality of peripheral openings. The central aperture includes the center point therein. The plurality of peripheral openings are disposed radially about the center point and in communication with the central aperture. The plurality of peripheral openings also includes at least one conjoined group of peripheral openings collectively in communication with the central aperture by way of a shared neck opening. The at least one conjoined group includes a first peripheral opening, a second peripheral opening, and a third peripheral opening.

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.

In some embodiments, a cutting system including a movable blade or a reciprocating blade operably coupled to a motor is disclosed, wherein the cutting system comprises a diverting feature. In some embodiments, a diverter proximity relative to the movable blade or reciprocating blade is selected to facilitate diversion of a material during cutting. In at least one embodiment, the movable blade may be movable blade for an oscillating tool. A cutting system according to the present invention may be coupled to a container, for example, a residential trash container or a residential recycling container.
