MANUALLY OPERATED FASTENING DEVICE

摘要

A fastening device is comprised of a housing having an operating lever pivotally mounted thereon. A striker is also located in the housing and oriented to drive a fastener from the housing. An actuator spring is coupled to the striker and adapted to bias the striker for driving the fastener from the housing. A firing lever is pivotally mounted on the housing and operable by the operating lever for raising the striker against the bias of the actuator spring. The firing lever is adapted to shift laterally relative to the striker and is normally located in a rest position. The firing lever is positioned to engage the striker when the operating lever is actuated to raise the striker. The firing lever is shifted laterally to release the striker for actuation by the actuator spring after the striker is raised. The firing lever is stopped in its rest position to locate the firing lever in a predetermined lateral position relative to the striker.
