Problems solved by technology

But present known energy-storage type stapler all has a common defect: 1, no matter how the thickness situation of paper to be bound, elastic member all works with same maximum deformation amount, easily occurs mechanical fatigue, shortens working life, 2. Even when binding thin paper, the maximum needle force is released, which is labor-intensive and easy to damage the paper. 3. For heavy-duty staplers with large changes in the thickness of the paper, the disadvantage of constant maximum needle force is in the binding of thin paper. especially noticeable on paper

Embodiment 1

[0068] Figures 4 to 7 show schematic diagrams of the assembly and disassembly structures of Embodiment 1 of the present invention in various states; The staple sheet 50 of the staple in the staple groove 30 is nailed and pressed, and an elastic needle pusher 31 is slidably fitted in the needle groove 30, and a needle plate 11 is provided on the base 10 corresponding to the position where the staple sheet 50 falls. , a bottom spring 12 is also provided on the base 10; the case 40 is hinged on the base, the upper cover 20 is above the book needle groove 30 and the case 40, and the upper cover 20 is hinged on the On the box 40, the staple sheet 50 slides up and down in the free end of the needle slot 30 and the box 40; and in the box 40, an elastic energy storage device 60 and its Energy release switch 70, the elastic energy storage device 60 includes an elastic firing end, the firing end is directly hooked on the nail sheet 50; The lifting distance between the book needle slots...

Embodiment 2

[0077] Figures 8 to 10 are schematic diagrams of the assembly structure of Embodiment 2 of the present invention in various states; except that the structure of the energy storage regulator 80 is different from Embodiment 1, other structures are the same as Embodiment 1. The structure of its energy storage regulator 80 includes a docking piece 81 that docks with the base 10 and an adjusting piece 82 that forms a mating relationship with the docking piece 81. The mating relationship is formed, specifically as follows: the docking member 81 is a docking frame fixed on the base 10 through the limiting groove 42 (see FIG. 5 ) at the bottom of the box 40; and the adjusting member 82 is simultaneously rotated and fitted on the The adjustment shaft in the hole of the docking frame 81 , the adjustment shaft 82 is also fitted in the middle of the torsion spring 62 .

[0078] Comparing Figures 9 and 10, it can be seen that: when the thick paper is loaded and pressed down, the position o...

Embodiment 3

[0080] Figures 11 to 14 are schematic diagrams of the assembly structure of Embodiment 3 of the present invention in various states; except that the structure of the energy storage regulator is different from Embodiment 1, other structures are the same as Embodiment 1. The structure of its energy storage regulator 80 includes a docking piece 81 that docks with the base 10 and an adjusting piece 82 that forms a mating relationship with the docking piece 81. The mating relationship is formed, specifically as follows: the docking member 81 is a docking frame fixed on the base 10 through the limiting groove 42 (see FIG. 5 ) at the bottom of the box 40: the adjusting member 82 is coaxial with the docking frame. The docking frame 81 is used as a hinged lock, and a pin 73 is provided at one end of the lock 82; on the lever 71B.

[0081] Comparing Figures 11 and 13, it can be seen that: the state of loading thick paper is pressed down, and the position of the box 40 is higher due to ...

Abstract

The invention relates to an energy-storage stapler with self-adjusting staple force, which comprises a base, an upper cover, a book needle groove or a box with a book needle groove inside it, and a stapler for pressing the staples in the book needle groove. Needle sheet: an elastic energy storage device and its energy release switch are installed in the needle slot or box, the elastic energy storage device includes an elastic firing end, and the firing end is directly or indirectly hooked or hinged on the needle sheet; An energy storage adjuster that converts the lifting distance between the base and the book needle trough into the corresponding elastic displacement of the energy storage device is also installed in the book needle trough or the box. The energy-storage stapler with self-adjusting needle force of the present invention, the elastic energy-storage part can automatically adjust the deformation amount according to the thickness of the paper to be bound, which reduces the number of fatigue work of the elastic-energy-storage part, prolongs the working life, and Automatically adjust the staple force according to the thickness of the paper to be bound, which saves effort and does not damage the paper when binding thin paper.

Description

technical field [0001] The present invention relates to an office stationery, more specifically, the present invention relates to a stapler. Background technique [0002] The energy-storage stapler uses elastic parts (such as springs, leaf springs, torsion springs, etc.) to store energy, and then releases the stored energy instantly, driving the staple sheet to impact the book needles instantly, realizing the function of high-energy staples, which has labor-saving , good nail effect and so on. This technology has just been used in the stapler industry in the past two years, and now countries all over the world are scrambling to develop this technology and use it in staplers. But present known energy-storage type stapler all has a common defect: 1, no matter the thickness situation of paper to be bound how, elastic member all works with identical maximum deformation amount, easily occurs mechanical fatigue, shortens working life, 2. The maximum needle force is released even...
