ABSTRACT:
A stapler has a body including two holes formed on two sidewalls thereof and a first link defined on one sidewall thereof. A magazine is assembly installed in the bottom of the body. A handle assembly includes a handle lever formed on an end thereof and a handle stop defined on another end thereof. A second link and a through hole are between the handle lever and the handle stop. A connector is disposed in the second link and pivotally couples to the two holes, and a first roller is inserted through the through hole and moves rotatably in the first link of the body. A power spring is disposed in the body, and a plunger includes a first hole and a second hole. When the handle lever is pressed downwardly and the handle stop lifts the plunger upwardly, the first roller is driven to move rotatably in the first link of the body to detach the handle stop from the plunger gradually.
