Magazine assembly for fastening tool

摘要

A magazine (100) for use with a fastening tool (1). The magazine can have a pusher assembly (110) that can be retracted into a recess (171) in the magazine to facilitate loading and reloading of fasteners (55). The magazine can also use a lockout mechanism which allows an operator to know when it is appropriate to reload fasteners and which can mitigate damage resulting from an impact upon the fastening tools nosepiece (12) when the lockout mechanism is engaged. The fastening tool can also have a contact trip actuator which is compact and can control the amount of force that is applied to a tactile switch of the fastener driving mechanism.
