摘要： An electronic processor of a wireless fob is configured to establish a first communication link between the wireless fob and an external device, and receive, over the first communication link, first identification information and credential information of a power tool device from the external device. The electronic processor is further configured to receive, via the wireless transceiver, an identification signal including second identification information from the power tool device. The electronic processor is further configured to identify the power tool device by determining that the first identification information matches with the second identification information. The electronic processor is further configured to transmit the credential information to the power tool device to establish a second communication link between the wireless fob and the power tool device and transmit, over the second communication link, a command to the power tool device to control an operation of the power tool device.

摘要： A method for removing oxidation of a contact of a trigger switch of a battery pack powered tool. The method includes receiving power from one or more battery packs coupled to the battery pack powered tool, determining, with a controller, that a trigger of the battery pack powered tool has been actuated, and providing, with a wetting circuit, power from the one or more battery packs to the contact to remove an oxidation surface film on the contact.

摘要： An impact power tool includes a motor, an output shaft to which a tool bit is attachable for performing work on a workpiece, and an impact mechanism disposed between the motor and the output shaft for converting a continuous torque output from the motor to discrete pulses of torque upon the output shaft, the impact mechanism including a cylinder assembly, a cavity defined within the cylinder assembly containing a hydraulic fluid, and a collapsible member having a first end and a second end opposite the first end. The collapsible member is maintained in a shape coinciding with that of the cavity by fitment within the cavity, with the first and second ends being disconnected from each other. The collapsible member is collapsible to compensate for thermal expansion of the hydraulic fluid during operation of the impact mechanism.

摘要： Various face shield assemblies for hard hats are described. In one embodiment, the face shield assembly includes a hard hat, a mounting bracket, a face shield, a first pivot arm and a second pivot arm. The first pivot arm and second pivot arm are pivotally coupled to the hard hat and rotate with respect to the mounting bracket and the face shield. The face shield is coupled to the first pivot arm and the second pivot arm. The face shield actuates between stowed and operating positions such that the face shield can avoid objects near a front of the hard hat, such as a bill and/or lamp. In other embodiments the face shield assembly includes an adjustable frame coupled to the face shield and the hard hat. The adjustable frame rotates and/or slides with respect to the hard hat.

摘要： Embodiments of the invention provide a ram assembly for a hydraulic tool. The ram assembly includes a ram piston having a ram cavity. The ram piston receives a hydraulic pressure reaction force. The ram assembly further includes an overload assembly disposed in the ram cavity or in a cavity defined by a manifold. The overload assembly includes a burst disc positioned at a first end of the ram cavity or manifold, a lock nut positioned at a second end of the ram cavity or manifold, and a spacer positioned between the burst disc and the lock nut. The spacer transfers a supporting force applied to the lock nut to the burst disc. The hydraulic pressure reaction force and the supporting force both act in the same direction, and thus, are additive forces acting on the burst disk.

摘要： An attachment configured for use with a powered hammer to drive a rod into the ground includes a body, an impact portion, and a driving portion in which the rod is receivable. The impact portion defines an impact axis and includes a bore configured to receive a driving shank coupled to the powered hammer. The impact portion is configured to receive repeated impacts from the powered hammer. The driving portion includes a side load driving portion defining a side load driving axis that is parallel to the impact axis. The driving portion further includes a top load driving portion defining a top load driving axis that is parallel to the side load driving axis.

摘要： Electronic spindle lock for a power tool. One embodiment provides a power tool including a housing, a bit receiving portion provided on the housing for receiving a power tool bit, a motor within the housing configured to rotate the bit receiving portion, and a controller coupled to the motor. The controller is configured to enter an electronic spindle lock mode, and detect rotation of the bit receiving portion in a first direction. The controller is also configured to control motor to rotate in a second direction in response to detecting rotation of the bit receiving portion in the first direction.

摘要： A gas spring-powered fastener driver includes a cylinder, a moveable piston positioned within the cylinder, a driver blade attached to the piston and movable therewith between a ready position and a driven position, a lifter to move the driver blade from the driven position to the ready position, and a transmission including an output shaft operatively coupled to the lifter to provide torque to the lifter. The fastener driver also includes an input to provide torque to the transmission and a clutch positioned downstream of the input and operably coupled to the output shaft to limit an amount of torque transferred to the output shaft and the lifter. In response to an application of a reaction torque to the output shaft above a predetermined threshold, torque from the input is diverted from the output shaft via the clutch.

摘要： A battery charger and a method of operating a battery charger. The charger may include a housing defining an air inlet and an air outlet; a charging circuit operable to output a charging current to charge a battery couplable to the battery charger; a tubular heat sink; and a fan operable to cause air flow from the air inlet to the air outlet and along the heat sink. The charger may include a first switch operable to electrically connect the charging circuit to a power source when the battery engages the charger; and a second switch operable to electrically connect the charging circuit to a battery terminal after the charger terminal is electrically connected to the battery terminal. The charging current or a fan speed may be adjusted based on at least one of the temperature of the charger or a temperature of the battery.
