Description

A kind of curved mechanism of prevention staple on stapler

Technical field

The present invention relates to the staplers for using staple that binding papers are bound into book form, more particularly to thicken stapler.

Background technique

The existing stapling devices using staple, including manually stapler, motor-driven stapler and self-control stapler The stapler of nail is all to make staple along staple guide groove indentation paper pile by applying pressure to staple, be finally completed dress It orders, but staple guide groove has opening, encounters excessive resistance Shi Huixiang open loop in staple, bookbinding failure, this is also to order Book machine has the reason of maximum bookbinding thickness.

Summary of the invention

The purpose of the application is to provide a kind of curved mechanism of prevention staple.

The technical solution of the present invention is as follows: a kind of curved mechanism of prevention staple on stapler, relevant stapler Component includes staple guide groove, staple, it is characterized in that further including that at least one prevents bending sliding block, at least one Flexible Reset Part, at least one guide part, the prevention bending slip front is an inclined-plane, this inclined-plane tilts down forward, the staple Nail contacts this inclined-plane when moving from the top down in forwarding, prevent bending slip front two sides from closing the staple and lead Slot, return springs one end connection prevent the bending sliding block other end from connecting the guide part or the stapler, reset bullet Property part to preventing bending sliding block from applying elastic force forward, guide part constraint prevents bending sliding block, allows its back-and-forth motion, guide part It is fixed in stapler.

Prevention bending slip front top is the inclined-plane, and lower part is facade.

The prevention bending sliding block is hollow.

The guide part is linear bearing structure.

The beneficial effect of the application is: preventing staple to be bent, increases the bookbinding thickness of stapler, smoothly complete bookbinding

Specific embodiment

Embodiment is set forth below to be further described the application.

Embodiment one, in conjunction with attached drawing 1 --- 4, a kind of curved mechanism of prevention staple, including 7 preventions are bent sliding block 111 and 2 prevention bending 112,9 return springs of sliding block are 13,1 guide part 12 of spring leaf, and the prevention is bent sliding block 111 front ends are inclined-plane, and the prevention bending 112 front end of sliding block is inclined-plane and facade, and the guide part 12 is generally square tube shape, resistance Only the block body of bending sliding block 111 and prevention bending sliding block 112 is placed in the square tube of guide part 12, and the fixing end of spring leaf 13 is fixed Bending sliding block 111 is prevented in the working end connection of guide part 12, spring leaf 13 and is prevented behind bending sliding block 112；By this machine Structure is applied to the general stapler using finished product nail, and the associated components for being related to stapler have nail-arranging slot 14, nail 15 and pressure Nail-plate 16；Guide part 12 is mounted on nail-arranging slot 14, prevents bending sliding block 111 and prevents front end and the nail-arranging slot of bending sliding block 112 It is contacted before 14, prevent bending sliding block 111 and prevents the front end side-closed of the bending sliding block 112 staple guide groove, The guide groove by before nail-arranging slot 14 and side, the nail 15 second staple before form；Pressure when bookbinding Nail-plate 16 moves down, and first staple of nail 15 is separated and moved down with nail 15 under the action of nail pressing plate 16, Be pierced into paper pile, later staple nail body with above first prevent bending sliding block 111 contact of incline plane, at this moment this inclined-plane, The nail body for constraining staple before nail-arranging slot 14 and below nail pressing plate 16 jointly, prevents its bending；Staple follows closely body simultaneously It forces first prevention to be above bent sliding block 111 by above-mentioned inclined-plane to move backward, be second later, third ..., Before the 7th prevention bending completion of sliding block 111 moves backward, staple pierces paper pile completely, and suffered resistance is become smaller by maximum, Staple, which continues to move down, forces 2 prevention bending sliding blocks 112 to move backward one by one, until bookbinding is completed, in the process, All 13 compression energy storage of spring leaf, then, nail pressing plate resets upwards, prevents bending sliding block 111 and bending sliding block 112 is prevented to exist It is also resetted in succession under the action of spring leaf 13, mechanism has been carried out to the curved resistance of staple in a complete forwarding Only.Bending 112 front end of sliding block is prevented to have one section of facade, when due to staple nail in by the facade, this section of staple guide groove It does not close, therefore bending ability is not prevented to this section of staple nail leg, that is to say, that compared with preventing to be bent sliding block 111, resistance Only bending effect is poor, but required quantity is also less, and structure is relatively easy, therefore penetrates paper in staple in the present embodiment After pile, setting prevents bending sliding block 112.

Embodiment two, in conjunction with attached drawing 5, reference implementation example one, including preventing bending sliding block 21, return springs is pressure spring 23 And 22 groups of cost mechanisms of guide part, this mechanism is applied to the stapler of self-control staple, is related to the associated components of stapler There are staple guide groove 24, staple 25；The square tube shape structure for preventing bending 21 pieces of bodies of sliding block from being placed in the guide part 22 In, 23 one end of pressure spring connection prevents behind bending sliding block 21, and the other end connects guide part 22, and guide part 22 is fixed in described Stapler prevents bending 21 front end two sides of sliding block from closing 24 inside opening of staple guide groove, and staple 25 is along staple guide groove 24 It moves down and is bound.Compared with embodiment one, because only one prevents bending sliding block 21, therefore structure is simple, but occupies empty Between it is big.

Embodiment three, in conjunction with attached drawing 6 --- 8, reference implementation example one, embodiment two is bent including 3 hollow preventions and slides The guide part that 31,3 groups of slide-bars 321 of block and sliding sleeve 322 form, the return springs and guide part bracket group of 3 groups of pressure springs 33 composition Cost mechanism, slide-bar 321 can move axially in sliding sleeve 322, and the affixed prevention in 321 front end of slide-bar is bent sliding block 31, sliding sleeve 322 Affixed guide part bracket, the bracket are installed on the stapler, and the pressure spring 33 is set in 322 periphery of sliding sleeve, front end connection Bending sliding block 31 is prevented, rear end connects the guiding trestle.Hollow prevention bending sliding block can save space, avoid with it is described The other component of stapler is interfered.
