Claims (1)

[Scope of Claim for Utility Model Registration] (1) A front-opening staple case consisting of main elements such as a push handle, a staple receiving base, a front-opening staple case, a staple pushing elastic plate, a staple feeder, and a telescopic support wedge. An opening is provided at the front end, and a guide bar seat is located on the bottom plate behind the opening, which is attached to the elastic element of the staple feeder and connected to the guide bar of the telescopic support wedge, and the guide bar is equipped with a suitable return spring. Installation: A telescopic support wedge is attached to the front end that moves elastically before and after the opening, the staple pushing elastic plate is in close contact with the upper inner side of the push handle, and there is a staple pushing at the front end, and after assembly, the staple pushing is just right. The telescoping support wedge is adapted to fit over the opening and has a wedge head at its front end and a distal end attached to a guide bar with an elastic element, the girth of the wedge being the same as that of the wedge and the inner wall of the staple case. The staple is inserted between the opening and the staple feeder is arranged so that it can move between the two, and when the staple pushing elastic plate presses down the staple at the opening, it applies downward pressure to the staple, while the staple pushing elastic plate applies downward pressure to the staple. The staple indirectly pushes the wedge backwards until it is completely driven in. During this process, the inside wall of the staple case, the side of the wedge, the staple being propelled, and the staple feeder drive the staple to be driven out. However, it provides full support to the circumferential side, strengthens the penetration power of the staples at each elbow and leg, and
This all-process support type stapler is characterized by a structure that eliminates the risk of the staple elbows and legs bending due to pressure or resistance due to the thickness of the booklet. (2) The stapler according to claim 1, wherein both bent sides of the front end of the staple case have openings equidistant from the inner widths of both staple legs. (3) The stapler according to claim 1 or 2, wherein the front end of the staple case is bent to form a folded edge and then spliced. (4) The stapler according to claim 3, wherein one of the folded edges is a male joining piece and the other is a female joining piece. (5) The lower bottom plate of the staple case opening has a notch with the same width as the opening, a rectangular sliding hole is provided at the rear of the notch, and a suitable downward cutout is provided below the wedge head of the telescoping support wedge. There is an auxiliary protrusion that protrudes to the same thickness as the bottom plate of the staple case, and there is a positioning screw for the staple on the flat part behind the protrusion, and it slides inside the rectangular sliding hole. The stapler according to claim 1 or 2, which is configured to be transferable. (6) The front end of the staple pressing elastic plate has a front support piece slightly smaller than one staple case opening in front of the staple pressing, and is slightly longer than the length of the staple pressing, and has a staple pressing and one inward staircase. 2. The stapler according to claim 1, wherein the stapler is formed of: (7) There is an elastic piece that extends forward and downward by folding back the rear end of the staple pushing elastic plate, and during the staple driving (stitching) process, this elastic piece pushes the rear upper part of the staple feeder and pushes the staple. The stapler according to claim 1 or 6, wherein the stapler is configured to increase the forward force.
