Abstract: An override mechanism for a nailer includes a nose unit, a magazine, a safety bar, a lever, a pivotal plate and a restriction member. The safety bar has one side slidably engaged with the guide slot of the nose unit. The lever has an extension and a pressing portion on two ends thereof. The pivotal plate has a base portion and an operation end, and the pivotal plate is pivotable relative to the extension of the lever. The operation end extends through the magazine and enters one of the grooves in the magazine. The operation end is located on the movement track of the side plate of the push plate. The restriction member is movably located in the longitudinal hole of the base. The user is acknowledged when a pre-set number of nails is remained in the magazine by restricting movement of the safety bar.
