摘要:
A power driver (500) may include a motor (590) that rotates upon receiving an input current. A tool chuck (550) may have chuck jaws to hold an accessory. The tool chuck (550) may be coupled to the motor. A power take off mechanism (510) may be connected between the motor (590) and the tool chuck (550). The power take off mechanism (510) may be adjustable into a CHUCK MODE to one of open and close the chuck jaws while the motor rotates. An electronic clutch (540) may interrupt the input current to the motor (590) if the power take off mechanism (510) is in the CHUCK MODE and if the input current exceeds a trip value.

A power driver may include a housing, a tool chuck (50) and a power take off mechanism (10). The tool chuck (50) may have an input shaft (60) mounted for rotation on the housing. The input shaft (60) may support chuck jaws. A chuck actuating shaft (64) may be mounted for rotation on the input shaft (60). The power take off mechanism (10) may be connected to the tool chuck (50). The power take off mechanism (10) may be adjustable into a DRILL DRIVE MODE to rotationally drive the input shaft (60) and the chuck actuating shaft (64) together as a unit, and a CHUCK MODE to rotationally drive the chuck actuating shaft (64) relative to the input shaft (60). The power take off mechanism (10) may be internal of the housing. The power take off mechanism (10) in the CHUCK MODE may rotationally fix the input shaft (60) to the housing.
