摘要： A power tool that includes a motor configured to drive a working element, a power supply that is coupled to the motor to provide power to the motor, a shunt circuit that is coupled to the power supply and the motor, and a controller. The shunt circuit includes a shunt switch and a shunt element and is configured to hold a voltage of the power supply below a high voltage threshold. The shunt switch is switchable between a conducting state, in which the shunt switch conducts current through the shunt element, and a non-conducting state, in which the shunt switch does not conduct current through the shunt element. The controller is coupled to the motor, the power supply, and the shunt circuit and is configured to determine the voltage of the power supply, and control the shunt switch based on the voltage from the power supply.

摘要： A light-guiding tool shank, a handle unit, a light-emitting element and a power allocation unit are assembled together to form a light-emitting fastening tool. The light-guiding tool shank includes a shank body, a light-guiding portion and a fastener fixing head. The shank body has a first and a second end; the light-guiding portion is formed in the shank body to locate between the first and the second end of the shank body; and the fastener fixing head is located at the first end of the shank body and defines a light projecting hole that is communicable with the light-guiding portion. With these arrangements, the light-emitting fastening tool enables a user to quickly sort out a desired fastener and align the same with a predetermined fastener fixing position even in a dark working environment or in the night, so that the fastener can be fixed in increased working efficiency.
