ABSTRACT:
A pneumatic stapler includes a housing having an elongated guiding passage for guiding a staple to be struck, a pneumatically operated stapling hammer for striking the staple located in the guiding passage and an elongated hollow staple magazine for connected separate staples. The magazine has a first end open into the guiding passage and a second end spaced from the first end along the elongation of the magazine. The staples are displaced along the magazine towards the first end thereof by air pressure supplied through a pneumatic nozzle connection located in the magazine between the first and second ends thereof. A spring pawl prevents movement of the staples located upstream of the nozzle connection towards the second end of the magazine.
