Drill tool shaft-to-housing locking device |
摘要 |
In a tool having an inner member supported within an outer member, wherein the tool defines a longitudinal axis, a device is provided for preventing relative rotation of the inner member and the outer member. The device is comprised of a locking mechanism and a locking actuator. The locking mechanism is positioned between the inner member and the outer member, wherein the locking mechanism is movable longitudinally between a first locking mechanism position in which the inner member and the outer member are disengaged and capable of relative rotation and a second locking mechanism position in which the inner member and the outer member are engaged and not capable of relative rotation. The locking actuator causes the locking mechanism to move longitudinally.
