  • Publication number: 20250060187
    Abstract: A bow string release includes a clip unit and a trigger. The clip unit includes a fork, two jaws, two springs and a roller. Each of the jaws includes an intermediate section pivotally connected to the fork. The first spring is compressed between the first and second jaws to open front ends of the first and second hooks. The roller is connected to a rear end of the first jaw. The second spring is pivotally connected to the fork. The trigger includes a first end extending from the fork, a second end pivotally connected to a rear end of the second jaw, and an intermediate section biased by the second spring. Thus, the intermediate section of the trigger pushes the roller and the lower end of the trigger moves the rear end of the second jaw, thereby moving the front ends of the first and second jaws toward each other.
