Nailer having mechanism for pre-positioning nail

摘要

A fastening tool can include a housing comprising a nosepiece and a handle. The handle can define a first longitudinal axis. A magazine can be connected to the housing for storing a fastener. The magazine can define a second longitudinal axis that is substantially parallel to the first longitudinal axis and a fastener channel for receiving a fastener. The magazine can be movable relative to the housing between an alignment position wherein the distal tip of the fastener engages a workpiece and an activation position wherein the magazine moves toward the housing upon movement of the handle toward the workpiece. A driving mechanism can be disposed within the housing for driving the fastener into a workpiece. A trigger assembly can be coupled to the housing for activating the driving mechanism upon actuation of a primary trigger and movement of the magazine into the activation position.

1. A fastening tool comprising:
a housing comprising a nosepiece and a handle, the handle defining a first longitudinal axis; a magazine connected to the housing for storing a fastener, the magazine defining a firing slot and a stabilizing surface, the magazine further defining a second longitudinal axis that is substantially parallel to the first longitudinal axis and a fastener channel for receiving a fastener, the magazine movable relative to the housing between an alignment position wherein a distal tip of the fastener engages a workpiece and an activation position wherein the magazine moves toward the housing upon movement of the handle toward the workpiece, wherein the fastener is guided along the firing slot to an engaged position with the stabilizing surface while the distal tip of the fastener remains engaged to the workpiece during initial movement of the handle toward the workpiece through a first distance from the alignment position to a position where the fastener is at the engaged position with the stabilizing surface, and wherein the handle is configured to subsequently move toward the stabilizing surface through a second distance to the activation position, wherein the fastener moves relative to the firing slot during movement of the handle through the first distance and is fixed relative to the firing slot during movement of the handle through the second distance; a driving mechanism disposed within the housing that advances through the firing slot for driving the fastener into a workpiece; and a trigger assembly coupled to the housing for activating the driving mechanism upon actuation of a primary trigger and movement of the magazine into the activation position, wherein movement of the magazine into the activation position is caused by interaction of the fastener on the stabilizing surface while the handle is moved toward the workpiece.
