摘要:
A hand-held power tool with a housing with a handle arranged along an axis, a trigger disposed in the housing and configured to operate the hand-held power tool, first and second sets of guide tracks coupled to one of the housing and the trigger and first and second sets of guides coupled to the other. The trigger, which includes a contact surface that is configured to be contacted by a finger of a user of the hand-held power tool, is movable between an extended position and a retracted position. The first and second sets of guide tracks guide the first and second sets of guides, respectively, such that movement of the trigger from the extended position to the retracted position causes the contact surface to move in a substantially constant direction having a first directional component and a second directional component, the first directional component being generally perpendicular to the axis of the handle and the second directional component being generally parallel to the axis of the handle.
摘要:
A method for assembling an activation arm assembly (804) for a power tool, such as a fastening tool or nailer. The method includes the mounting of various components of the activation arm assembly on pivot pins (854,856) and positioning of a pair of arm members (870) to load a spring (858) that biases one of the arm members relative to another of the arm members.

A tool with a driver (32), a motor (40), a structure to which the motor is coupled and a return cord (1052) assembly. The driver that is translatable along an axis between an extended position and a retracted position. The motor is configured to translate the driver from the returned position to the extended position. The return cord assembly is coupled to the driver and the structure and includes a spring (1082) and an elastomeric return cord (1080) that are employed to return the driver from the extended position to the retracted position.
摘要:
A method for calibrating a power tool having a roller (852), a driver (32) and a solenoid (810,44). The solenoid has a body and a rod (820) and is coupled to the roller so as to be capable of selectively advancing the roller toward the driver. The method includes: locating the roller onto a predetermined portion of the driver; moving the body of the solenoid in a first direction until the occurrence of a first predetermined condition, the first direction being in a direction that causes the roller to be driven toward the driver; after the occurrence of the first predetermined condition, moving the body of the solenoid in a second direction opposite the first direction until the occurrence of a second predetermined condition and thereafter securing the body of the solenoid to inhibit further movement of the body of the solenoid.
摘要:
A power tool with a flywheel (42), an activation arm (806), a driver (32), a cam and a clutch (800). The activation arm can have a first arm, a second arm, which can be pivotally mounted to the first arm, and a roller (808) 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.
