Referring to fig. 1, a stapler for office use comprises a base 1, a staple holder 2 for placing staples is movably installed on one side of the surface of the base 1, a thimble block 3 slidably connected with the inner wall of the staple holder 2 through a guide rod is provided, one end of the thimble block 3 is fixedly installed with a thimble spring 4, one end of the thimble spring 4 is movably installed with the inner wall of the staple holder 2, a pressing base 5 rotating with the staple holder 2 is movably installed on the surface of the base 1, a pressing plate 50 for pressing the staples on the staple holder 2 is fixedly connected with one side of the bottom surface of the pressing base 5, and a force-applying arm 8 is hinged with the inner wall of the pressing base 5, meanwhile, a support rod 6 is hinged with the inner wall of the bottom of the base 1, and one end of the support rod 6 is fixedly connected with a positioning baffle 7, so that the pressing plate 8 is pulled out during the work process, thereby increasing the length of the force-applying arm 5, further its pressure seat 5 of increase is at the arm of force length of pressurized in-process, meanwhile, the bracing piece 6 through its base 1 bottom stretches out, the area of contact of base 1 bottom has not only been increased, prevent that its extension of pressing seat 5 from and lead to its base 1 to appear fixed unstable phenomenon, meanwhile, through the locating baffle 7 of its setting, not only can fold into base 1 inner chamber when bracing piece 6, jack-up its base 1 through its locating baffle 7, because its locating baffle 7's surface area is little, and then increase the frictional force of its base 1 bottom, further reinforcing stability, still roll over the back through its bracing piece 6, realize treating the location of ordering the paper through its locating baffle 7, thereby increase the locate effect to its paper.

Please refer to fig. 2, wherein, in order to position different papers, the supporting rod 6 is set as a telescopic rod, so that the extension length of the supporting rod 6 can be adjusted, and the paper with different lengths can be adjusted adaptively, thereby further enhancing the accuracy of the position of the paper during binding, and meanwhile, the stability of the base 1 during binding is further increased by the lengthened supporting rod 6.

Referring to fig. 3 and 4, in order to realize the bending deformation of the staple during the binding process of the over-thick paper, a driving block 14 located at one side of the thimble block 3 is movably installed on the inner wall of the thimble seat 2, and one end of the driving block 14 penetrates through the end of the thimble seat 2 and is located at the outer side of the thimble seat 2, so that the thimble block 3 is pushed by the thimble spring 4 to realize the deadlocking of the staple with the driving block 14, a probe 16 is movably installed on the inner wall of the driving block 14, a compression spring 15 is fixedly installed on the inner wall of the driving block 14, one end of the compression spring 15 is fixedly installed on the inner wall of the probe 16, and an ejection block 9 adapted to the driving block 14 is movably installed at one side of the surface of the force applying arm 8, so that the force applying arm 8 and the pressure seat 5 are relatively horizontal by bending of the force applying arm 8 when binding the thick paper, in the process of pressing downwards through the force applying arm 8, the air release channel 11 is propped against the driving block 14, so that the driving block 14 goes deep inwards, the thimble spring 4 is compressed through the staples and the thimble block 3, in the process of continuously pressing downwards through the force applying arm 8, the staple firstly penetrates through paper through the pressing force of the probe 16, after the force applying arm 8 is lifted, the driving block 14 is reset through the compression spring 15 and the thimble spring 4, so that the staples are positioned below the staple pressing sheet 50, and the staple pressing sheet 50 presses the staples through withdrawing the force applying arm 8 and directly pressing the pressing seat 5 downwards, so that the stress of the staples is reduced in the process of penetrating the staples, and the phenomenon of leading deformation of the staples is prevented.

Referring to fig. 3 and 5, in order to realize continuous use without retracting the force application arm 8 in the using process, a return spring 10 is fixedly installed on the inner wall of the force application arm 8, one end of the return spring 10 is fixedly installed with the ejection block 9, a gas release channel 11 communicated with the inner cavity of the ejection block 9 is formed on the surface of the ejection block 9, a sealing ball 12 for realizing the connection and disconnection of the gas release channel 11 and the inner cavity of the ejection block 9 is placed in the inner cavity of the ejection block 9, meanwhile, a pressure relief groove 13 for relieving pressure in the force application arm 8 is formed on the side wall of the force application arm 8, and the pressure relief groove 13 is a small hole, so that in the working process of the pressure application arm 8 and the pressure base 5 are horizontal, at this time, the sealing ball 12 seals the gas release channel 11 due to gravity, and air flow in the inner cavities of the ejection block 9 and the force application arm 8 can only escape from the pressure relief groove 13, and in the process that the air escape channel 11 continuously extrudes the driving block 14 downwards, the air escape channel 11 can also synchronously retract into the stress arm 8, after the stress arm 8 is lifted, the quick recovery can be realized because the resetting of the probe 16 and the driving block 14 is subjected to the elasticity of the compression spring 15 and the thimble spring 4, but when the ejection block 9 is recovered by the elasticity of the reset spring 10, the air flow can only be supplemented from the pressure groove 13 because of the blockage of the air escape channel 11, so that the air escape channel 11 is slowly pushed out, further after the stress arm 8 is lifted, when the air escape channel 11 is not completely recovered, the pressing is carried out again, so that the staple can be pressed by the needle pressing sheet 50, and further the staple passes through the hole ejected by the probe 16, thereby the phenomenon that the staple directly passes through the paper and the deformation of the staple is reduced, when the air escape channel 11 is quickly recovered, only part of the stress arm 8 is needed to be bent, make the ball 12 of blocking break away from the air release path 11 by gravity, can impel the arm of force 8 inner chamber to carry out quick tonifying qi through air release path 11, therefore at the in-process that needs continuous binding, only need to realize punching in advance through pulling arm of force 8 and binding the purpose of carrying out the binding to increase the efficiency of its binding and the fixed intensity of binding needle.

Referring to fig. 6, in order to realize the pre-punching process, the phenomenon of too large punching hole does not occur, so that the probe 16 is designed to be u-shaped, the top end of the probe 16 is provided with a sharp corner, and the probe 16 is made of hard alloy, so that in the actual use process, only the width of the probe 16 needs to be overcome, which is close to or smaller than the size of the existing staple in the market, so that the staple can be fixed in diameter after the probe 16 is punched with the pre-punched hole, and the phenomenon of untight binding of the staple due to too large pre-punched hole is avoided.

Referring to fig. 5, in order to prevent the driving block 14 from being pressed and the position between the probe 16 and the needle pressing plate 50 from deviating a lot, the height between the inner wall surface of the needle clamping seat 2 and the bottom surface of the driving block 14 is set to be one centimeter, so that the driving block 14 contacts the inner wall of the needle clamping seat 2 when the driving block 14 is pushed towards the inner cavity of the needle clamping seat 2 by the height difference between the inner wall of the needle clamping seat 2 and the driving block 14, and the probe 16 is further positioned below the needle pressing plate 50, thereby ensuring the normal pushing out of the probe 16.

Referring to fig. 1 and 2, in order to ensure that the force arm 8 and the support rod 6 are pulled out, the force arm 8 can be used to increase the applied pressure and increase the support force for the support rod 6, so that the movable angles of the force arm 8 and the support rod 6 are both between zero degrees and one hundred eighty degrees, and thus, when the force arm 8 and the support rod 6 are at the zero-degree position, the whole base 1 has no difference from the existing market shape, and after the support rod 6 and the force arm 8 are all at one hundred eighty degrees, the support strength is enhanced, and the applied strength is also enhanced.

The using method (working principle) of the invention is as follows:

the staple is placed in the staple holder 2, the thimble block 3 is pushed by the thimble spring 4 so that the staple is placed on one side of the driving block 14, the supporting rod 6 is pulled out and pulled to a proper length, and the positioning of the paper to be stapled is realized by the positioning baffle 7;

when the number of bound paper is less: the ejection block 9 is directly pressed, the pressing seat 5 is synchronously pressed downwards through the ejection block 9, the stitching sheet 50 on the pressing seat 5 pushes out the stitching, and the stitching of the paper on the base 1 is realized through the stitching;

when the number of bound papers is large: the stress arm 8 is pulled out to realize the relative level between the stress arm 8 and the press seat 5, the stress arm 8 is pressed to move downwards, the ejector block 9 on the stress arm 8 firstly contacts the driving block 14 and extrudes the thimble spring 4 through the staple and the thimble block 3 through the driving block 14, at the moment, the side wall of the driving block 14 is attached to one side of the inner wall of the staple seat 2, the probe 16 is positioned below the probe sheet 50, in the process of pressing downwards through the press seat 5, the probe sheet 50 presses the probe 16 downwards and extrudes the compression spring 15, the probe 16 firstly forms a hole on the paper and ejects, at the moment, the air release channel 11 continuously presses downwards, the return spring 10 is compressed, the air flow in the inner cavity of the stress arm 8 is extruded from the pressure groove 13, and after the probe 16 penetrates through the paper, the stress arm 8 is lifted, the probe 16 is retracted under the elasticity of the compression spring 15, and under the elasticity of the thimble spring 4, the staple can push the driving block 14 to reset, meanwhile, through pressing the pressure seat 5 downwards again, because the air current of the inner cavity of the forcing arm 8 can only be slowly filled from the pressure groove 13 at this moment, the air escape way 11 can not be completely recovered, and when the pressure seat 5 is pressed downwards again, the staple is ejected by the staple pressing sheet 50 and is bound along the pre-punched hole, thereby completing the binding of more sheets.
