Problems solved by technology

[0002] The patent with the publication number CN102335903A discloses a labor-saving stapler, which adds an auxiliary upper cover and realizes labor-saving operation with the principle of double levers, but because the lower end of the auxiliary upper cover is hinged at the front end of the base, the upper end of the auxiliary upper cover The first transmission pin is slidingly connected in the first chute of the upper cover, so that the lower end of the auxiliary upper cover cannot move, and the second transmission pin on the nail pressing plate is located near the front end of the nail pressing plate. , so that the upper end of the auxiliary upper cover and the first chute are closer to the middle position of the upper cover, so that when the upper cover is pressed down, the resistance arm of the upper cover is longer, so that the labor-saving effect cannot be optimal, and the upper cover can be opened The angle is small, making it less convenient to put staples into the nail channel

Abstract

The invention discloses a stapler, which comprises a bracket seat, a nail path, an upper blade assembly, a hinge and an upper cover. At the rear end, the side wall of the upper cover is provided with a first guide portion, and one end of the hinge is slidably connected to the first guide portion, and the first guide portion is arranged to enable one end of the hinge to go up to the cover when the upper cover is pressed down. The rear end of the hinge moves and presses down, the side wall of the bracket seat is provided with a second guide part, the other end of the hinge is slidably connected to the second guide part, and the second guide part is set to be up When the cover is pressed down, the other end of the hinge can move to the front end of the bracket seat, and when the upper cover is opened, the other end of the hinge can be separated from the bracket seat, and the middle position of the hinge is hinged with the middle position of the upper blade assembly. The guide portion is close to the rear end of the upper cover. The present invention has better labor-saving effect and is more convenient to place the staples.
