摘要： A power tool with a flywheel, an activation arm, a driver, a cam and a clutch. The activation arm can have a first arm, a second arm, which can be pivotally mounted to the first arm, and a roller that can be coupled to the second arm. The driver can be disposed between the roller and the flywheel. The cam can be moveable in a predetermined direction for causing the activation arm to rotate about a pivot to drive the roller against the driver so that the driver frictionally engages the flywheel. The clutch can cooperate with the cam to inhibit the cam from moving in a direction opposite the predetermined direction in response to a reaction force that is applied by the driver onto the activation arm.

摘要： A bit retaining system for a rotary tool or device such as a router is disclosed. The bit retaining system may include a collet assembly and a control assembly. The collet assembly may include a spindle, a collet adapted to receive the bit, and a collet nut. The collet assembly may further include a collet gear mounted on the collet nut and/or a spindle gear mounted on the spindle. The control assembly selectively engages the collet assembly to drive the collet nut and/or secure the spindle in a fixed position, preventing its rotation. In operation, a hand tool is utilized to engage the control assembly. This configuration enables a user to capture and release the rotary tool bit using one hand.

摘要： A power tool for drilling a hole in a workpiece made of wood or a wood material. The power tool generally includes a tool housing defining a handle and a motor contained within the tool housing that includes an output shaft that spins about a motor axis. A gear housing is connected to the tool housing. An output spindle is supported for rotation about a spindle axis in the gear housing. The spindle axis is disposed about ninety degrees from the motor axis. A gear portion on the output shaft is engaged to a gear portion on the output spindle. The motor and the gear portions are configured to rotate the output spindle at a speed in range from about five thousand revolutions per minute to about twenty-five thousand revolutions per minute. A cutting member is connected to the output spindle. The cutting member includes fluted cutting blades. A carriage assembly includes a base member and a head member connected by a first post having a first compliant member and a second post. The head member slides relative to the first and second posts and against a force exerted by the first compliant member when the head member is moved toward the base member to pass the cutting member through the base member to engage the workpiece. The base member includes a generally planar face on a bottom surface of the base member that is generally perpendicular to the spindle axis.
