[0026] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0027] For example, Figs. 1 to 4As shown, an improved stapler, comprising a base 1, a base 2, a stapling part 3 and a nail storage box 4, one end of the base 2 is hinged to the base 1, the other end of the base 2 and the base 1 form a stapling opening, specifically, the base 2 has a rectangular accommodating cavity, the nail storage box 4 is movably arranged in the accommodating cavity of the base 2 along the length direction of the base 2, one end of the stapling part 3 is hinged to the base 1, the other end of the stapling part 3 is located above the base 2, a nail sheet 31 is installed on the stapling part 3 above the base 2, the nail sheet 31 is used to press out the book nail in the nail storage box 4, the above structure adopts the structure in the front pull type stapler in the prior art and known technology, the nail storage box 4 can be pulled out from the front of the stapler to replace the book nail; the front pull type structure of the above nail storage box 4 is the prior art, for example, the structure of the nail storage box disclosed in the Chinese utility model patent with the publication number "CN211390650U" and the name "a protection device for the nail sheet of a stapler" mentioned in the background art, the front pull type structure of the above nail storage box 4 can also adopt other conventional structures in the field, as long as the nail storage box 4 can be pulled out from the front of the stapler to replace the book nail.

[0028] Unlike the prior art, the stapling part 3 of the utility model is fixed with a stop block 32 near the position of the nail sheet 31, the bottom of the stop block 32 extends downward and is located at the top of the side wall of the nail storage box 4, the side wall of the base 2 in the stapler in the embodiment is higher than the side wall of the nail storage box 4, accordingly, the first retreat groove 21 for the stop block 32 to extend into is opened on the base 2 corresponding to the position of the stop block 32, the second retreat groove 41 for the stop block 32 to extend into is opened on the nail storage box 4 corresponding to the position of the stop block 32; when the stapler works normally, the nail sheet 31 is pressed down to realize the stapling operation, the stop block 32 can extend into the first retreat groove 21 and the second retreat groove 41, when the nail storage box 4 is pulled out, the first retreat groove 21 of the side wall of the nail storage box 4 is dislocated with the second retreat groove 41 on the side wall of the base 2, at this time, the stop block 32 is located in the second retreat groove 41 and at the top of the side wall of the nail storage box 4, the stop block 32 is blocked by the side wall of the nail storage box 4 so that the stapling part 3 cannot be pressed down; in this way, when the operator forgets to place the nail storage box 4 in place after filling the book nail, even if the stapling part 3 moves downward by mistake, the stapling part 3 will first press against the side wall of the nail storage box 4 under the action of the stop block 32, avoiding the collision between the nail sheet 31 and the nail storage box 4 to cause the breakage and damage, after the nail storage box 4 returns to the original position, the first retreat groove 21 returns to the original position, the stop block 32 can extend into the first retreat groove 21 and the second retreat groove 41, and the stapler can restore normal work.

[0029] The improved stapler of the utility model, through setting stopper 32 on binding part 3, and corresponding first retreat slot 21 and second retreat slot 41 are set on base 2 and nail storage box 4, avoid the case that the operator misoperation makes binding part 3 downward movement leads to nail sheet 31 breakage damage, compared with prior art, the structure of the utility model is simple, and the anti-collision structure adopts pure mechanical structure, and the use cost is low.

[0030] Further, the base 1 is also provided with a flat nail device for flattening the two feet of the book nail, the flat nail device comprises a flat nail seat 5 capable of swinging up and down relative to the base 1, the flat nail seat 5 is provided with a flat nail groove 51 at one end corresponding to the binding opening, the other end of the flat nail seat 5 is hinged to the base 1, specifically, the flat nail groove 51 is provided along the width direction of the flat nail seat 5, and the flat nail groove 51 penetrates the upper and lower sides of the flat nail seat 5, a return spring 6 is further arranged between the base 1 and the flat nail seat 5, the return spring 6 is arranged at a position close to the flat nail groove 51, two bent nail plates 52 are arranged side by side in the flat nail groove 51, the ends away from each other of the two bent nail plates 52 are respectively hinged to the inner wall of the flat nail groove 51, and the base 1 is provided with a horizontally arranged bearing plate 11 corresponding to the position of the flat nail groove 51, and the bearing plate 11 is located below the flat nail groove 51.

[0031] When the binding part 3 is not pressed, the bottom of the bent nail plate 52 protrudes from the bottom of the flat nail seat 5, when the binding part 3 is pressed, the nail sheet 31 presses the book nail in the nail storage box 4 out, the two feet of the book nail are respectively inserted into the flat nail groove 51 and touch the upper surfaces of the two bent nail plates 52 in the flat nail groove 51, and the two feet of the book nail respectively apply downward force on the upper surfaces of the two bent nail plates 52 in the process of continuously being pressed, and the pressing of the binding part 3 drives the base 2 to press down, so that one end of the flat nail groove 51 of the flat nail seat 5 moves downward and compresses the return spring 6 at the bottom of the flat nail groove 51, so that the bottom of the two bent nail plates 52 in the flat nail groove 51 touches the bearing plate 11 on the base 1, the two bent nail plates 52 swing upward and inward around the respective hinge points, and the upper surface of the bent nail plate 52 always abuts against the corresponding foot of the book nail, so as to slowly bend the two feet of the book nail, when the bottom of the flat nail seat 5 completely abuts against the bearing plate 11, the bottom of the bent nail plate 52 also abuts against the bearing plate 11, at this time, the upper surface of the bent nail plate 52 is in the same plane as the upper surface of the flat nail seat 5, so that the upper surfaces of the two bent nail plates 52 completely flatten the two feet of the book nail, thereby completing the whole flat nail action, and then the binding part 3 is reset, and the flat nail seat 5 and the two bent nail plates 52 are reset under the rebounding action of the return spring 6.

[0032] Further, since the nail sheet 31 is subjected to a large force and is prone to damage after long use, the upper end of the nail sheet 31 in the embodiment is detachably connected with the binding part 3, so that the nail sheet 31 can be replaced alone when the nail sheet 31 is damaged, which is convenient to operate.

[0033] While the embodiments of the present application have been illustrated and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the spirit and scope of the application, which is defined by the appended claims and their equivalents.
