  • Publication number: 20240100658
    Abstract: A powered ratchet includes a motor, a mounting portion, and an output member configured to rotate in response to activation of the motor. The output member defines a drive axis. The powered ratchet also includes a release mechanism configured to selectively couple an anvil to the output member. The release mechanism includes a cover coupled to the mounting portion with a track and a locking member positioned between the mounting portion and the cover and operable to slide within the track between a locked position, in which the locking member engages the anvil to secure the anvil to the output member for co-rotation therewith, and a release position, in which the locking member is disengaged from the anvil to facilitate removal of the anvil. The release mechanism also includes a biasing member biasing the locking member to the locked position.
