Stapler for box edges to press end of iron core by double pulling of handle bar

A stapler for box edges to press an end portion of an iron core by double pulling of a handle bar which includes:

• a lower plate 100 having an iron core support plate formed at an end of one side of an upper portion thereof to make an iron core 201 of the stapler bent, the iron core support plate gradually getting wider downward from the top and having inclined surfaces respectively formed at both sides of the upper portion and fitting portions extending downward from ends of the inclined surfaces;
• an iron core storage part 200 of which an end portion is coupled with one side of the lower plate 100 by a hinge, into which a plurality of iron cores 201 are inserted in a horizontal direction, and which has an iron core outlet selectively discharging the iron core inserted into the iron core storage part, an iron core pushing member pushing the iron cores 201, a fixing rod which is formed on the opposite side of the iron core pushing member, and a first pushing elastic member of which one side is connected to the iron core pushing member and the other side is connected to the fixing rod;
• an upper plate 300 of which one side is connected with the hinge, and which is disposed above the iron core storage part 200 and has a second pushing elastic member disposed therein to be connected with one side of the iron core storage part 200;
• insertion spaces which are respectively formed between the iron core support plate and the iron core storage part 200 in different directions so that sides of a fabricated box can be put therein;
• and an operating means, of which one side of an upper portion is located inside the lower plate 100 and the upper plate 300 and the other side is located below the lower plate 100, and which has a handle bar 410, a fixing member, a moving pin 430, and a pulling elastic member so that a user can operate the stapler by pulling the handle bar, the stapler comprising:
• a first load bar 1100 formed on the lower plate 100 and having a pushing groove 1101 formed at a predetermined angle, a sliding groove 1103 formed to be slidable in the back-and-forth direction, and a fixing groove 1105 to which a fixing pin is coupled;
• a second load bar 1200 connected with the fixing pin of the first load bar 1100;
• a third load bar 1300 of which one side is connected with the second load bar 1200 by a fixing pin and the other side is connected to the lower plate 100;
• a rack 2100 disposed inside the iron core support plate 110 and vertically sliding through a sliding pin connected to the sliding groove 1103 of the first load bar 1100;
• rotary gears 2200 respectively disposed at both sides and engaging and rotating with the rack 2100 sliding vertically;
• and
• pressing plates 2300 respectively disposed at both sides of the outer face of the iron core support plate 110 and connected with the rotary gears 2200 by fixing pins.
