The specific embodiment

By reference to the accompanying drawings, the present invention is described in further detail.

As shown in the figure, stapler of the present invention, it is characterized in that: described stapler comprises base arm 40, upper arm 50 and attachment pegs 70 and middle groove 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, and cylinder 71 is arranged on the attachment pegs 70; Porose 2 510 on the described upper arm 50, provide four recessed 2 530 and four projectioies 73 on the field of conjugate action of upper arm 50 and the attachment pegs 70, recessed 2 530 can be corresponding mutually with projection 73; The part of accepting staple on the described stapler includes top board 3 80 and base front end 48, pin groove 81 and downward cylindrical structure 82 are arranged on the top board 3 80, screwed hole 83 and four projectioies 2 84 are arranged on the cylindrical structure 82, through hole 401, not through hole 402 and four projectioies 2 403 are arranged on the base front end 48, and the diameter of through hole 402 is not greater than the diameter of through hole 401.Described screw 5 can be screwed in the 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 by spring 2 405 and is threaded in the hole 83, and spring 2 405 can be fitted with the upper surface of through hole 402 not.A turning cylinder is arranged on the described holder 74, and the axle of itself and screw 5 is in a straight line.Described convex upper arm 51 and convex base arm 42 have 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 respectively.Oriented outer lug 2 511 and to outer lug 411, two shallow slots 2 512 and two shallow slots 1 respectively on described spill upper arm 51 and the spill base arm 41, its corresponding contraction place 3 513 and contraction place 1, also corresponding extension place 3 514 and uphold in the place 414 one of them.On the described upper arm 50 extendible space is arranged, it is limited to outer lug 2 511, inwardly protruding 2 521, and extendible space is also arranged on the base arm 40, and it is limited to outer lug 411, inwardly protruding 1.The convex base arm 42 of described 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 by top board 2 53, top board 1 respectively.Described attachment pegs 70 is perpendicular to upper arm 50, and projection 2 75 is arranged on the free end 702 of attachment pegs 70, and is 55 corresponding with on the upper arm 50 recessed.

As shown in the figure, the present invention is a stapler, rotatable 360 degree, and can prolong.Wherein, upper arm 50 and base 40 arms can prolong.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 to outer lug.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 shrink again correspondingly and uphold and to outer lug.Therefore convex arm and spill arm can slide and mesh, and when upper arm 50 and base arm 40 reached capacity, inwardly outside projection can make it to stop to slide.For simple operations, extension place of convex arm has aperture, is used for mounting spring and globule, and globule closes on inside projection; Corresponding with it contraction spill arm has a lot of shallow slots in glide direction, can be temporarily fixing globule.Attachment pegs 70 1 ends can rotate flexibly around the upper arm front end, 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 and projection mesh, attachment pegs 70 1 ends can both keep tight engagement with the upper arm front end.Fig. 2 has showed the parts that the present invention and common stapler generally all comprise.As shown in Figure 2, be positioned at accepting the staple position and needn't rotate together with attachment pegs 70 on the base arm 40.As shown in Figure 4, the position of accepting staple comprises top board 3 80 and base front end 48, and pin groove 81 is arranged on the top board 3 80, and downward cylindrical structure 82 has 83 and four projectioies 2 84 with threaded hole on the cylindrical structure 82.Base front end 48 comprises through hole 401, is used 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 is by spring 2 405, is screwed into to be threaded in the hole 83, makes spring 2 405 and the upper surface of through hole 402 not be close to.So this position of design is for it can be rotated synchronously with attachment pegs 70, making pin groove 81 be positioned at needed position.

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