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.
Claims21
A hammer-type stapler with cartridge for driving staples into target piece comprising
- a casing having a front portion and a handle connected with a distal end of said front portion;
- a replaceable cartridge installed in said front portion;
- a pushing device slidably mounted in said handle;
- a hollow hammer casing extended from an opposing end of said front portion, said hammer casing including a front wall, a back wall, a pair of opposite side walls and an upper opening, said upper opening;
- a driving unit embedded on said side walls of said hammer casing;
- said front portion including a top wall, a pair of opposite side walls and a lower opening, said lower opening extended to said front wall of said hammer casing, said top wall of said front portion connected with said back wall of said hammer casing, said side walls of said front portion connected with said side walls of said hammer casing and respectively formed a cartridge-taking opening thereon adjacent to said lower opening;
- a cartridge matching unit installed on an internal surface of said front wall of said hammer casing for guiding said driving unit moved smoothly up and down;
- and
- a bracket with two ends respectively affixed on said side walls of said hammer casing adjacent to said cartridge matching unit for holding the cartridge;
- wherein
- said handle including a top wall, a lower wall and a pair of opposite side walls with a distal opening formed on an end thereof, said top wall formed a locking hole thereon adjacent to said distal opening, a lock pin installed in said pushing device and plugged in said locking hole;
- and
- said cartridge composed of two identical, upper and lower, opposite staple containers, said staple containers respectively protruded a pair of parallel tracks from each opposite top surface therein, a staple pusher and said staples slidably installed on said tracks and pushed by the pushing device, two staple-outlets respectively formed on said staple containers, and two steel pads respectively mounted on said staple-outlets for protecting said cartridge against cutting and abrasion from the driving element.
A cartridge for various wide staples used in said hammer-type stapler with cartridge could load various size staples comprising:
- a pair of two identical, upper and lower staple containers, formed opposite to each other, and a staple pusher mounted therein;
- said staple containers including a pair of parallel tracks protruded from each opposite top surface therein defining an E-shaped groove, and a staple pusher slidably mounted on said tracks for pushing staples loaded thereon, said staple pusher having a staple-like shell and a block;
- said staple container having as sealer formed on an end thereof for preventing said stapler pusher slipped off, two staple-outlets respectively formed on two ends thereof, two steel pad respectively mounted on said staple-outlets, said blockmatch with steel pad result in said staple pusher not projected out said staple-outlet, and two metal coverings respectively pivoted on two end thereof;
- said metal covering including two lateral surfaces respectively bended from said side distal portion of the metal covering thereof, a front hood formed between said two lateral surfaces adjacent to said staple-outlet, and an upper opening formed above the front hood, said front hood could having two protruding ears respectively formed on two ends of said lateral surfaces;
- whereby
- exactly guided said driving element to drive staples, and prevented staples slipped off said staple-outlet, so that by setting a width of said lateral surfaces adapted to different staples, said cartridge for various wide staple could accommodate to staples of different width.
A hammer-type stapler with cartridge for driving staples into target piece comprising:
- a casing having a front portion and a handle connected with a distal end of said front portion;
- a hollow hammer casing extended from an opposing end of said front portion;
- a driving unit vertically mounted in said hammer casing for driving said staple with a vertical action;
- a replaceable cartridge installed in said front portion;
- a pushing device slidably mounted in said handle for pushing said staples in said cartridge to a driven position under said driving unit;
- and
- a metal hammering plate mounted on a top of the hammer casing whereby said hammer-type stapler with a function of being a hammer.
