Abstract
A hammer-type stapler with cartridge is a tool using in building working for driving staples into a working object, comprising a casing having a hollow hammer casing on the front portion of the casing for containing a driving unit. The driving unit moves vertically by inertia force and having a driving element for driving staples, and an elastic element for recoiling the driving unit. A replaceable cartridge is installed in the casing and adjacent to the driving element having two identical, upper and lower staple containers. A pushing device is slidably mounted in the casing for holding the cartridge and pushing staples. The cartridge can load different size staples.
