ABSTRACT:
A stapler has a center of gravity and has a base assembly, a magazine assembly and a trigger assembly. The magazine assembly connects to the base assembly and has a cap. The trigger assembly connects to the base assembly and has a trigger lever and a limiting lever. The limiting lever prevents the trigger lever and the cap from pivoting excessively to keep the center of gravity of the stapler over the base assembly so that refilling the stapler is convenient.
