CUTTING DEVICE WITH INTEGRATED AND INTERRUPTIBLE AUXILIARY POWER SUPPLY
An improved cutting device with an integrated and interruptible auxiliary power supply is disclosed herein. In a preferred embodiment, the improved cutting device is a miter saw having a trigger mechanism for controlling a cutting implement, and at least one 120V or 240V auxiliary power outlet. Electrical power is only provided to the cutting implement and the auxiliary power outlet when the triggering or a similar mechanism is activated, and the release of the triggering mechanism by the user automatically shuts off electrical power to both the cutting implement and the at least one auxiliary power outlet. The auxiliary power outlet is useful for powering any number of different accessories including, without limitation, a light, vacuum source, etc., and is repositionable.
Working machine
A working machine includes: an output shaft to which a tip tool is attachable; a housing rotatably supporting the output shaft; and a protection cover attached to the housing so as to cover an outer periphery of the tip tool which is attached to the output shaft. The protection cover is configured to be displaceable between a processing position to expose a part of the outer periphery of the tip tool to thereby allow cutting of a workpiece, and a protecting position to cover the outer periphery of the tip tool more than in the processing position, and is biased by a biasing member to be displaced from the processing position to the protecting position.
Cutting device
A cutting device main body with a saw blade in a tabletop cutting device, supported so as to be swingable in an up-to-down direction with respect to a table on which material to be cut is placed, aims to improve operability for attaching and detaching the battery. A sliding direction for attaching and detaching the battery is set to be a tilting direction angled with respect to an up-to-down moving direction of the cutting device main body in a surface direction of a cutting blade. Because of this configuration, all of an operation force for attaching and detaching the battery is not applied to the up-to-down moving direction of the cutting device main body. As a result, the cutting main body is not moved in an easy manner and operability for attaching and detaching the battery is improved.
Line trimmer/mower with twist grip throttle control
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.

Electric static discharge protection for power tools
A power tool has a housing, a motor disposed within the housing, a power supply circuit for providing power to the motor, a controller circuit for controlling the power provided to the motor, and an electric static discharge (ESD) protection circuit connected to the power supply circuit and the housing. The ESD protection circuit includes a first resistor connected to the power supply circuit and the housing. The first resistor may be a high impedance resistor. The ESD protection circuit may also have a first capacitor connected in parallel to the first resistor, a second resistor connected in series to the first resistor, and a second capacitor connected in series to the first capacitor and in parallel to the second resistor.
Apparatus and method for automated blade change for tissue saw
A blade storage array is detachably mountable with a tissue log cutting saw. The saw has a cutting arm with a tool holder receptacle adapted and configured to hold a circular saw blade for the saw. The array has a plurality of storage units. Each storage unit is adapted and configured to store a circular saw blade for the saw. Each storage unit has a tool holder receptacle adapted and configured to hold a circular saw blade. Each storage unit is adapted and configured to move perpendicularly to the saw blade center axis.

Cutting machine
To provide a cutting machine that suppresses swinging of the cutting portion when the battery pack is attached or detached, the cutting machine includes a cutting portion, a base, and a swing support mechanism. The cutting portion includes: a motor, a motor housing accommodating the motor, an output shaft configured to be rotated upon rotation of the motor, a battery pack serving as a power source of the motor, and a battery pack attaching portion including a pair of rail portions with which the battery pack is engageable, where a cutting blade is configured to be detachably attached to the output shaft. The base has a contact surface on which a workpiece is configured to be placed. The swing support mechanism is connected to the base and the cutting portion and includes a swing shaft extending in parallel to the output shaft. The swing support mechanism supporting the cutting portion such that the cutting portion is swingable about the swing shaft between a top dead center and a bottom dead center in a direction parallel to a side surface of the cutting blade. The pair of rail portions extend in a direction crossing the side surface of the cutting blade.
