Abstract
An anti-release mechanism of a pin-grabber coupler securing a work tool connected to a work machine is disclosed. The anti-release mechanism comprises an actuator, a wedge, a latch, a guide rod connecting the wedge and the latch, and a bias member on a first guide rod end of the guide rod biasing the latch and the wedge together. The wedge and the latch lock around a pin of the work tool and maintain the wedge against the pin of the work tool during a loss of engagement force of the wedge against the pin.
