The following specific embodiment further specifies the present invention in connection with above-mentioned accompanying drawing.
The specific embodiment
Referring to figs. 1 to Fig. 3, paper holder 100 comprises pallet 10, the driver train 40 that slides and be arranged at two clip boards 20, the loam cake 30 on this pallet 10 and be arranged at pallet 10 bottoms.Paper 200 is positioned on this pallet 10 and between above-mentioned two clip boards 20.When the user opened loam cake 30, described driver train 40 drove 20 motions of two clip boards, and then adjusted the distance between two clip boards 20.Pallet 10 runs through and offers two straight line chutes 11 and a slide opening 12, and described two chutes 11 are straight line alignment mutually.Described slide opening 12 is positioned near the drift angle of pallet 10.The bottom of pallet 10 convexes with the first registration mast 13, the second registration mast 14 and baffle plate 15, and wherein the first registration mast 13 is positioned at the centre of above-mentioned two chutes 11.
Each clip board 20 comprises a holding part 21 and the driving handle 22 that is fixed in these holding part 21 bottoms.Described driving handle 22 passes above-mentioned chute 11 and respectively offer the first tooth-strip part 23 on its relative surface.
The biside plate 32 that loam cake 30 comprises a cover plate 31 and extends along equidirectional from cover plate 31 both sides, described biside plate 32 rotates respectively and is fixed on the two side ends of above-mentioned pallet 10.Cover plate 31 vertical protrusion on the end face of pallet 10 has among the two parallel fixed leg 33(figure and only shows a fixed leg 33, and another is blocked by side plate 32).
The thick induction mechanism 41 of paper rotates and is fixed between two fixed legs 33 of loam cake 30, is used for the thickness H of induction paper 200 and acts on 42 motions of the first skewback.The thick induction mechanism 41 of paper comprises intermediate bar 411, is fixed in the cam 412 on intermediate bar 411 1 ends and is fixed in induction rod 413 on intermediate bar 411 other ends.Cam 412 comprises curved surface 4120, and described curved surface 4120 reduces gradually apart from the length in cam 412 axle center.Described induction rod 413 is fixed with two rollers 4130 from the vertical extension of intermediate bar 411 1 ends and at its end.Under induction rod 413 Action of Gravity Fields, described roller 4130 contacts with paper 200 all the time.When the thickness H of paper 200 reduced, described induction rod 413 can drive the cam 412 that is fixed in intermediate bar 411 other ends and rotate.
The first skewback 42 is arranged at slidably in the slide opening 12 of pallet 10 and when loam cake 30 was in closure state, the cam 412 of the thick induction mechanism 41 of described paper contacted with the top of the first skewback 42.The second skewback 43 slides and is arranged at the bottom of pallet 10, and it arranges and mutually align with baffle plate 15 near above-mentioned the second registration mast 14.The first skewback 42 comprises that the first inclined-plane 420, the second skewbacks 43 comprise with the second inclined-plane 431 of the first inclined-plane 420 corresponding applyings and towards the second tooth-strip part 432 of the second registration mast 14.In the middle of present embodiment, described elastic component 44 is for being arranged at compressively the coil spring between the second skewback 43 and the baffle plate 15.
The first gear 45 and the second gear 47 are rotationally connected respectively to first registration mast 13 and the second registration mast 14 of above-mentioned pallet 10, and the both sides of described transmission handle 46 are corresponding to be provided with respectively two the 3rd tooth-strip parts 460 with the first gear 45 and 47 engagements of the second gear.Second tooth-strip part 432 of described 45 whiles of the first gear with the second skewback 43 meshes.First tooth-strip part 23 of described 47 whiles of the second gear with above-mentioned two clip boards 20 meshes, and therefore can drive two clip boards 20 and slide along chute 11 when it rotates.
With reference to figure 4, shown in loam cake 30 be in closure state, described cam 412 and the first skewback 42 are supported so that the distance of described two clip boards 20 is slightly less than the width of paper 200, this moment elastic component 44 be in confined state.When loam cake 30 is switched to open mode, described cam 412 and the first skewback 42 break away from, described elastic component 44 is replied and is acted on 43 motions of the second skewback and then drive the first gear 45 and clockwise rotates, described transmission handle 46 effects the second gear 47 rotates counterclockwise, and then drive two clip boards 20 and move dorsad so that the distance of its two holding part 21 increases to the width greater than paper 200 gradually, therefore can conveniently paper 200 be put between two clip boards 20.
After paper 200 places, shown in loam cake 30 be switched to closure state shown in Figure 4.At this moment, the curved surface 4120 of described cam 412 contacts and acts on it with the first skewback 42 and moves away from cam 412 until described two rollers 4130 are supported paper 200 along slide opening 12.Described the first skewback 42 can act on 44 motions of the second skewback 43 compression elastic pieces away from cam 412 motions, and then drive the first gear 45 and rotate counterclockwise, clockwise rotate so that described transmission handle 46 drives the second gear 47, and then drive two clip boards, 20 move toward one another so that the distance of its two holding part 21 is decreased to gradually less than the width of paper 200 and applies Clamping force F on paper 200.
Please in the lump with reference to figure 5, reduce gradually along with paper 200 is used thickness H, the described induction rod 413 that is fixed in intermediate bar 411 1 ends rotates and drives the cam 412 that is fixed in intermediate bar 411 other ends relative to loam cake 30 and rotates.Because curved surface 4120 structures of cam 412, described elastic component 44 is replied so that 43 motions of the second skewback, and then act on the first gear 45, transmission handle 46 and the second gear 47 corresponding sports, thereby so that two clip boards 20 move dorsad, so that the distance of its two holding part 21 increases gradually and then so that put on the Clamping force F of paper 200 and reduce gradually.Until during thickness H to a particular value of described paper 200, described Clamping force F is reduced to 0, therefore can avoid paper 200 folder arches.
