The specific embodiment

By reference to the accompanying drawings, the utility model is described in further detail.

As shown in the figure, the utility model stapler, it is characterized in that: described stapler comprises base arm 40, upper arm 50 and attachment pegs 70 and middle slot 60, upper arm 50 is divided into spill upper arm 51 and convex upper arm 52, base arm 40 is divided into spill base arm 41 and convex base arm 42, has cylinder 71 in attachment pegs 70; Porose 2 510 on described upper arm 50, in the field of conjugate action of upper arm 50 and attachment pegs 70, provide four recessed 2 530 and four projections 73, recessed 2 530 can be mutually corresponding with projection 73; The part of accepting staple on described stapler includes top board 3 80 and base front end 48, on top board 3 80, there are pin groove 81 and downward cylindrical structure 82, on cylindrical structure 82, there are screwed hole 83 and four projections 2 84, on base front end 48, have through hole 401, not through hole 402 and four projections 2 403, the diameter of through hole 402 is not greater than the diameter of through hole 401.Described screw 5 can be screwed in screwed hole 2 72 by spring 7, spring 7 can be fitted with through hole 520 lower surfaces not, screw 2 404 is screwed into and is threaded in hole 83 by spring 2 405, and spring 2 405 can be fitted with the upper surface of through hole 402 not.What be in a straight line with the axle of screw 5 is a turning cylinder on holder 74.Described spill upper arm 51 and convex base arm 42 have respectively extension place 4 525 and extension place 2 425, contraction place 4 526 and contraction place 2 426, inwardly protruding 2 521 and inwardly protruding 1, aperture 2 522 and aperture 1, spring 4 523 and spring 3 423, globule 2 524 and globule 424.In described spill upper arm 51 and spill base arm 41, there are respectively outwardly convex 2 511 and outwardly convex 411, two shallow slots 2 512 and two shallow slots 1, its corresponding contraction place 3 513 and contraction place 1, also corresponding extension place 3 514 and uphold one of them in a place 414.On described upper arm 50, have extendible space, it is limited by outwardly convex 2 511, inwardly protruding 2 521, also has extendible space in base arm 40, and it is limited by outwardly convex 411, inwardly protruding 1.The convex base arm 42 of described convex upper arm 52, spring 4 523, globule 2 524 and spill base arm 41, spring 3 423 and globule 424 gather together, and are hidden respectively by top board 2 53, top board 1.Described attachment pegs 70 is perpendicular to upper arm 50, has projection 2 75 on the free end 702 of attachment pegs 70,55 corresponding with on upper arm 50 recessed.

As shown in the figure, the utility model is a stapler, 360 deg rotating displaying, and can extend.Wherein, upper arm 50 and base 40 arms can extend.Upper arm 50 comprises convex upper arm 52, and it can be upheld and shrink, and can inwardly protruding; Also should comprise spill upper arm 51, it can shrink accordingly with convex upper arm 52 and uphold and outwardly convex.Base arm 40 comprises convex base arm 42, and it can again be upheld and shrink and inwardly protruding; Also comprise spill base arm 41, it can again shrink correspondingly and uphold and outwardly convex.Therefore convex arm and spill arm can slide and mesh, and when upper arm 50 and base arm 40 reach capacity, inwardly outside projection can make it to stop to slide.For simple operations, extension place of convex arm has aperture, and for mounting spring and globule, globule closes on inside projection; The contraction spill arm of answering in contrast has a lot of shallow slots in glide direction, can be temporarily fixing globule.Attachment pegs 70 one end can be around upper arm front end flexible rotating, and the field of conjugate action of this end and upper arm front end have the projection of a large amount of rules and corresponding recessed with it, they can rotate around the axle of attachment pegs 70, no matter whether recessed like this meshed with projection, attachment pegs 70 one end can both keep closely engagement with upper arm front end.Fig. 2 has shown the parts that this utility model and common stapler generally all comprise.As shown in Figure 2, be positioned at accepting staple position and needn't rotate in base arm 40 together with attachment pegs 70.As shown in Figure 4, the position of accepting staple comprises top board 3 80 and base front end 48, has pin groove 81 on top board 3 80, and downward cylindrical structure 82 has 83 and four projections 2 84 with threaded hole on cylindrical structure 82.Base front end 48 comprises through hole 401, for placing cylindrical structure 82; Through hole 402, and its diameter is greater than through hole 401 diameters; Four corresponding recessed 403 with it.Screw 2 404, by spring 2 405, is screwed into and is threaded in hole 83, and spring 2 405 and the upper surface of through hole 402 are not close to.Like this this position of design is in order to allow it can synchronize with attachment pegs 70 rotation, to make pin groove 81 be positioned at needed position.

Ensuing a few width figure can also see that the position of accepting staple is the cross pin groove 81 being positioned in base arm.When four direction that the direction of top board 3 80 and base front end 48 embodies in as this utility model, pin groove 81 can both be worked.In addition, have projection 2 75 on the free end 702 of attachment pegs 70, and on upper arm 50, have recessed 55 of correspondence position with it, so that this stapler more closely meshes in home position, attachment pegs 70 is just positioned under upper arm 50.
