A powered working machine facilitating work of fixing a tip tool to a tool supporting member is provided. A powered working machine in which a tip tool is driven by power of an electric-powered motor includes: an output shaft to which the tip tool is attached; a tool fixing member which fixes the tip tool to the output shaft; a second shaft to/from which the tool fixing member is attached/detached; a clamp having a locked state in which a state of attachment of the tool fixing member to the second shaft is maintained and an unlocked state in which the tool fixing member can be detached from the second shaft; and a guide member having a first rotation position at which the clamp is in the locked state and a second rotation position at which the clamp is in the unlocked state.

An oscillatory driving device for a hand-held power tool includes at least one input shaft, at least one output shaft, and at least one gearing unit. The gearing unit operatively connects the input shaft to the output shaft and includes at least one eccentric element configured to drive the output shaft in an oscillatory manner. The gearing unit includes at least one further eccentric element configured to drive the output shaft in an oscillatory manner.

The cordless power cutter that is lightweight and weight-balanced between a power section housing a battery pack as a power source and a cutting section including the motor in a belt-free drive system and rotatable disk blade. The weight balancing of the cordless power cutter allows the tool to remain parallel to a horizontal surface, such as the ground, without tilting, when the operator lifts and holds the tool by only a gripping or transverse portion of the lifting handle. The motor has a motor axis that is not perpendicular to the disk axis and that is rearward of the disk axis to provide a depth of cut. The weight-balance and motor positioning allows the cordless power cutter to achieve ease of handling and operation.

An accessory tool for an oscillating power tool includes a blade portion including a first lateral edge portion, a second lateral edge portion, and a leading edge portion, the leading edge portion defining a cutting edge. A reinforcement structure extends linearly across the blade portion from a first position located on the leading edge portion proximate the first lateral edge portion to a second position located on the second lateral edge portion and spaced apart from the leading edge portion. The reinforcement structure defines a cutting zone that encompasses a leading region of the blade portion between the reinforcement structure and the leading edge portion, the reinforcement structure being configured to increase a stiffness of the blade portion.

A wheeled mount for handheld tools with a frame having an upper and lower region, a pair of handles attached to and projecting away from the upper frame region, an 5 axle attached to the lower frame region, a pair of wheels in contact with a generally horizontal surface and further fixed to the axle and a handheld tool positioned on or within and secured to the lower frame to position the attachment of the handheld tool in contact with the generally horizontal surface thereby creating a stable three point contact for the wheeled mount for handheld tools. An operator can safely operate and move the wheeled 10 mount for handheld tools in a manner similar to using a hand dolly.
