    • A jaw arm for an associated compression tool having cam rollers that displace forwardly and rearwardly along an axis to pivot the jaw arm includes a recess and a notch. The recess is disposed adjacent a forward end of the jaw arm. The notch is axially spaced rearwardly from the recess. The recess is configured to receive an associated pipe and an associated coupling for compressing at least one of the associated pipe and the associated coupling to mechanically attach the associated pipe to the associated coupling when the jaw arm is pivotally displaced toward at least one of the associated pipe and the associated coupling. The notch is configured to receive an associated cam roller of the associated compression tool and to retain the associated cam roller to inhibit axial rearward movement of the associated cam roller when the associated cam roller has been received in the notch. A pressing tool and a jaw set incorporating the aforementioned jaw arm is also disclosed.
    • 用于相关压缩工具的颚臂具有沿轴线向前和向后移动以枢转颚臂的凸轮辊,包括凹槽和凹口。 所述凹槽设置在所述钳口臂的前端附近。 凹口从凹部向后轴向间隔开。 所述凹部构造成接收相关联的管道和相关联的联接器,用于压缩相关联的管道和相关联的联接件中的至少一个,以在颚臂枢转地朝向相关联的管道 管道和相关的联轴器。 所述凹口被构造为接收相关联的压缩工具的相关联的凸轮辊并且当相关联的凸轮辊已经被接收在所述凹口中时,保持相关联的凸轮辊以阻止相关联的凸轮辊的轴向向后运动。 还公开了一种包括上述颚臂的按压工具和钳口组。
