Keyless chuck operation device |
摘要 |
A main body formed generally as a hollow cylinder has an open end sized to receive a chuck head into the main body. An outer shell formed generally as a hollow cylinder is mounted to the main body. A gear drive assembly is mounted to the main body and engaged with the face gear of the chuck. The outer shell is selectively manually engagable with the outer shell via a the gear drive assembly such that rotating the chuck head opens or closes the jaws of the chuck, depending upon the direction of rotation. The outer shell has a free wheeling position in which a person may grasp the outer shell and hold it to guide the drill without causing the chuck jaws to tend to open or close.
