摘要： A power tool is provided including a tool housing in which an electric motor is disposed. The electric motor includes a stator and an armature rotatably received within the stator. The armature has an armature shaft on which a commutator is mounted. The power tool further includes at least one brush assembly disposed around the commutator, the brush assembly including: a brush having two grooves on opposites surfaces therein; a brush holder comprising two support plates arranged defining guiderails that extend into the grooves of the brush to facilitate movement of the brush along a single axis; and a spring contacting the brush that urges the brush radially inwardly along the axis.

摘要： A power tool having one or more sound damping members which reduce sound and/or vibration from one or more parts of a power tool. The sound damping member can reduce sound and/or vibration from static or dynamic parts of a power tool. The sound damping member can reduce noise and/or vibration from one or more rotating or moving parts of a power tool and its housing or internal structure. Methods, means, controls, systems and practices for reducing or eliminating undesired sound from a power tool are disclosed.

摘要： A handheld power tool is configured to receive an input indicative of a clutch setting for an electronic clutch from the tool operator, where the clutch setting is selectable from a drill mode, an automated drive mode and one or more user-defined drive modes. Each of the user-defined drive modes specifies a different value of torque at which to interrupt transmission of torque to the output spindle. In an automated drive mode, the controller interrupt torque to the output spindle in an automated manner when a fastener being driven reaches a desired stopping position. In a selected one of the user-defined drive modes, the controller sets a value of a maximum current threshold in accordance with the selected one of the user-defined drive modes and interrupts torque to the output spindle when current measures exceeding the maximum current threshold.

摘要： A hedgetrimmer having a blade assembly that converts between a straight blade configuration and a curved blade configuration. The blade assembly includes a support bar for securing a pair of cutting blades. The support bar is made up of a plurality of rotatable support links allowing the support bar to curve. A switch assembly includes a rigid wire fixedly secured to the support bar. The rigid wire extends and retracts, moving the support bar between its straight and curved configuration.

摘要： A high inertia driver system for a fastening tool having an electric motor that drives a flywheel to contact a driver blade to drive a fastener into a workpiece. The high inertia driver system also has a return system which prevents the unintentional driving of a second fastener. The return system uses a return spring that controls the recoil energy of the driver blade after driving a fastener into a workpiece. The system achieves a long operational life for the fastening tool by increasing the number of return cycles of the driver blade free of a return spring failure.
