Patent ID: 7464845

Claim:
A hand-held staple gun, comprising: a housing, including a left side, a right side and a front side, and defining an internal space which includes an accommodation chamber; a safe actuation mechanism, including a swing means, a link and an actuation control rod, wherein the swing means is pivotally secured to the housing, the link is pivotally connected with the swing means, the swing means and the link are biased by a torsion spring, and the actuation control rod has a first end stretching downward and out of the housing and has a second end pushing upward and touching the swing means such that the actuation control rod is biased by the elastic force of the torsion spring; a driver, being movably disposed in the internal space of the housing and spaced apart from and paralleled with the actuation control rod of the safe actuation mechanism, and being driven out of the housing by an elastic force; a spring means, being disposed on the driver so as to provide the driver the elastic force and thus fire staples; and a handle, being pivotally secured to the housing and activating the link when pressing down of the handle; whereby, when the staple gun is not in use, the link cannot engage the driver even if the handle is pressed down, and when the staple gun is in use, the actuation control rod is pressed upward into the housing, so that the actuation control rod pushes the swing means, making the link engage the driver, where the driver, being biased by the spring means, is moved upward when the handle is pressed down, and when the handle is pressed down continuously, the link releases abruptly from the driver, making the driver rush downward so as to drive the staples out of the staple gun, through the help of the elasticity force of the spring means.
