binary springs, 52 pairs of hole axles, 53 ejector pin groove parts, 54E type meson, 55E type meson, 56 self-tapping screws, 57 self-tapping screws, 58 machine screw mech scrs, 59 machine screw mech scrs, 60 machine screw mech scrs, 61 chrysanthemum mesons, 62 chrysanthemum mesons, 63 nuts, 64 little depression bars, 65 microswitches, 66 straight burr axles, 67 push away and pull 68 locating pieces, 69 springs, 70 fixed blocks, 71 self-tapping screws, 72 light emitting diodes, 73 transformers, 74 power lines, 75 wiring boards, 76 installation sheets, 77 microswitches, the bright lamp driver plate of 78 low nails, 79 briquettings, 80 self-tapping screws, 81 camber members etc.As Fig. 2---shown in 7, when the file of need bookbindings touches little depression bar 64 and when triggering microswitch 65, motor 15 is rotated counterclockwise through geared system drive eccentric wheel 35 and rotates to an angle; rocking arm 34 is also swung certain angle thereupon; rocking arm 34 drives levers 31 around 24 rotations of four hole axles; four cheat axle also is with " U " the shape support is used for restriction nail groove cover and swings.Motor continued to be rotated counterclockwise when the switch engine part 33 on being fixed on lever 31 triggered microswitch 29, at this moment, lever 31 drives blade 38 and overlaps 46 front ends to lower slider along the nail groove, while spring 32 will be followed closely groove cover 46 and press down, file (paper) is compacted, blade 38 will be followed closely the staple release in the groove 39 subsequently, and bending forming will be followed closely by 13 places at nail-plate.After the nail shaping, motor 15 continues to be rotated counterclockwise, and lever 31 drives blades 38 and upwards slides, and blade 38 drive nail groove covers 46 elastic force that overcome spring 32 move upward simultaneously, and nail groove 39 is forced to unclamp file.Motor cuts off the power supply immediately and stops operating when switch engine part 33 discharges microswitches 29, and can shift out the file of ordering this moment.Subsequently, the nail pushing devices 44 in the nail groove 39 are pushed ahead staple under the active force of tension spring 45, can " empty not beating " when ensureing next nailing.The nail groove 39 of this machine blocks by being contained in optical axis 49, the binary spring 51 that the nail groove overlaps 46 afterbodys, when dress staple or cleaning barrier, with hand make by pull 5, optical axis 49 overcomes the elastic force of binary spring 51 to moving down, nail groove 39 is ejected by binary spring 51 immediately, cleans out barrier and loads onto and will follow closely groove 39 behind the staple and push chucking and get final product.This machine supports the usefulness of the flexible glue 23 of four hole axles 24 as the power buffering, guarantees the staple forming quality.Transmission device comprises geared system, eccentric wheel apparatus, rocking arm, lever, blade etc.Power to d.c. motor through transformer from civil power, motor 15 closely cooperates with motor gear 16, and power is reached middle gear 19 by pinion 17, reaches gear wheel 20 again.Gear wheel 20 is coaxial with eccentric wheel 35, the eccentric wheel 35 outer rocking arms 34 that are with, and rocking arm 34 is terminal to be connected with single hole T nail 36 with lever 31 is terminal, and lever 31 front ends catch on blade 38, and lever 31 can rotate around four hole axles 24, and blade 38 can overlap 46 front portion slips along the nail groove.Gear wheel 20 is passed to eccentric wheel 35 with moment of torsion like this, and eccentric wheel 35 drives rocking arm 34 swings, and rocking arm 34 drives lever 31 and rotates, and lever 31 drive blades 38 overlap 46 front portions along the nail groove and slide up and down, thereby realizes the purpose of nailing.In the dynamo-electric signal switch, when the file of need bookbindings touches little depression bar 64 and when triggering microswitch 65, motor 15 begins to be rotated counterclockwise under the starting circuit effect, by reduction gearing at different levels, eccentric wheel, rocking arm, lever transmission of power is done the up-and-down reciprocating motion to blade.When blade 38 moves downward, being fixed on switch engine part 33 on the lever 31 triggers microswitches 29 and starts and accept circuit and make motor 15 continue to be rotated counterclockwise, motor 15 stopped operating when switch engine part 33 discharged microswitches 29 when directly only blade 38 moved upward, and finished one time forwarding this moment.When the remaining a small amount of of staple in the nail groove, nail pushing device 44 triggers the microswitch 77 that is fixed on the catapult frame (descending) 47, and light emitting diode 72 is lighted, and prompting will add staple.Microswitch is for adapting to staple and the different distance requirement of file binding limit, and the device that design can front and back slidable adjustment microswitch 65 mainly pulls 67 by pushing away, locating piece 68, spring 69, fixed block 70, little depression bar 64, microswitch 65 form.Fixed block 70 will push away and pull 67, locating piece 68, spring 69, little depression bar 64, microswitch 65 are locked on the left shell 2.7 scales (gear) are arranged on the platform 11, corresponding with it on the left shell 2 have a positioning boss, locating piece 68 is compressed by spring 69 elastic force effects and left shell 2 between positioning boss, pushing away during adjusting pulls 67 overcomes spring 69 elastic force and gets final product slidable adjustment, pushing away pulls 67 rests on a certain scale (gear), push away 67 corresponding platform 11 scales (gear) of pulling, the bookbinding position that sets exactly.Follow closely the groove push-on process as shown in Figure 8: before nailing begins, will follow closely groove 39 with hand and push, nail groove 39 is blocked by the optical axis 49 on the nail grooves cover 46, in the process, along with the variation of binary spring 51 angles is subjected to torsion and stores elastic force.Nail groove ejection process is as shown in Figure 9: when needing dress staple or cleaning barrier, trigger by pulling after 5 with hand, ejector pin groove part 53 forces optical axis 49 to move down, while binary spring 51 is pressurized also, fetter when optical axis 49 breaks away from nail groove 39, binary spring 51 discharges elastic force, will follow closely groove 39 and eject.Nail groove tail apparatus structure is seen accompanying drawing 10, mainly is made up of camber member 81, shell fragment 42, shell fragment nest nail 43 etc.Camber member 81, shell fragment 42, shell fragment nest nail 43 are loaded on nail groove 39 tails, and shell fragment 42 is pushed down camber member 81.In the time will adorning staple or cleaning barrier, click by pulling 5 with hand, machine driving binary spring 51 discharges elastic force, because the nail groove overlaps 46 bottom empty avoidings, one segment distance, camber member 81 can be ejected out to the nail groove with nail groove 39 and overlap on the inclined-plane, 46 end, make nail groove 39 stop to send or being lowered the speed that nail groove 39 ejects, available hand will follow closely groove 39 and pull out this moment: camber member 81 tail ends on the nail groove 39 overlap 46 inclined-planes and up slide along following closely groove, force shell fragment 42 distortion, when being pulled out to nail groove that the nail groove overlaps 46 front ends and pulling out spacing place, because the nail groove overlaps 46 end empty avoidings, one segment distance, shell fragment 42 resets, the camber member of following closely on the groove 39 81 is colluded in the nail groove pull out spacing place, the length of pulling out of nail groove 39 has arrived terminal point.As shown in figure 11, control circuit include power supply circuits, starting circuit, accept circuit, the state of awaiting your instructions, positive and
