Abstract
Bearing pieces are formed on both sides of the rear end of a clincher arm which includes a clincher table for bending a staple at the front end thereof. A magazine member to which staples are loaded and a driver arm for driving out a staple fed from the magazine member are pivotally mounted on an axle, which is provided at the rear ends of the bearing pieces. A handle member is rotatably disposed above the driver arm. A rotation supporting shaft of the handle member is provided at a position somewhat closer to the front than the axle of the bearing pieces. A pin, which is provided at a position closer to the front than the rotation supporting shaft of the handle member, is inserted into an elongated hole formed in each side plate of the driver arm.

A boosting mechanism for a stapler, wherein:
- bearing pieces are formed on both sides of a rear end portion of a clincher arm which includes a clincher table for bending a staple at a front end portion thereof;
- a magazine member, to which staples are loaded, and a driver arm for driving out a staple fed from the magazine member are pivotally mounted on an axle, which is provided at rear end portions of the bearing pieces;
- a handle member is rotatably disposed above the driver arm;
- a rotation supporting shaft of the handle member is provided at a position closer to the front end portion than the axle of the bearing pieces;
- and
- a pin, which is provided at a position closer to the front end portion than the rotation supporting shaft of the handle member, is inserted into elongated holes formed in side plates of the driver arm.
A boosting mechanism for a stapler including a clincher arm having a clincher table for bending a staple at a front end portion thereof, a magazine member to which a plurality of the staples are loaded, a driver arm for driving out the staple fed from the magazine member, and a handle member rotatably disposed above the driver arm, said boosting mechanism comprising:
- bearing pieces formed on both sides of a rear end portion of the clincher arm;
- an axle provided at rear end portions of said bearing pieces wherein the magazine member and the driver arm are pivotally mounted on said axle;
- a rotation supporting shaft provided to the handle member at a position closer to the front than said axle;
- a pin provided at a position closer to the front end portion than said rotation supporting shaft;
- and
- elongated holes formed in side plates of the driver arm wherein said pin is inserted into said elongated holes.
A stapler comprising:
- a clincher arm including a clincher table for bending a staple at a front end portion thereof and bearing pieces formed on both sides of a rear end portion thereof;
- a magazine member to which a plurality of the staples are loaded;
- a driver arm for driving out the staple fed from the magazine member, said driver arm including elongated holes formed in side plates of said driver arm;
- a handle member rotatably disposed above said driver arm;
- an axle provided at rear end portions of the bearing pieces wherein said magazine member and said driver arm are pivotally mounted on said axle;
