具体实施方式
下面结合附图、实施例对本发明作进一步说明。
为方便叙述，将订书机钉板移动前的位置称为正常位置，钉板移动后的位置称为省力位置。所使用的方位词，如前、后等均为按特定方向进行描述，而不是对本发明保护范围的限制。
实施例1。
如图1、图2所示，省力订书机包括：上盖1、钉道组件2、用于支撑上盖1和钉道组件2的支架座3、用于与钉道组件2配合的钉板4、底座5，支架座3安装在钉板4上，所述的上盖1和钉道组件2均通过转轴与支架座3转动连接，上盖1上装有用于推顶订书针的刀片1.1，上盖、钉道组件以及钉板相配合实现装订。
本发明省力订书机与传统订书机的不同之处在于：其还包括辅助压板6，所述的辅助压板6与底座5转动连接，所述的辅助压板6与上盖1之间设有带动上盖1摆动的连接机构，所述的钉板4滑动连接在底座5上，通过锁紧机构锁住钉板4。
设置辅助压板6并通过连接机构作用于上盖上，等于延长了上盖力臂，因此，可以提高上盖对订针的压力，能够装订更厚的纸张，或者装订时更为轻松省力。
为了更好地增加辅助压板的力臂，还将上盖、钉道组件以及顶板后移，即相对底座后移至省力位置。由于辅助压板和底座连接，辅助压板不移动，上盖后移后，辅助压板对上盖的施力力臂增加。
上述上盖摆动是指装订时辅助压板6带动上盖的工作过程，上盖会相对辅助压板6进行摆动，并不局限于这种形式，其本质是辅助压板6带动上盖下压而完成装订过程。
本实施例中，所述的辅助压板6为一端开口、另一端封闭的凹槽，开口端的两侧壁设有支撑臂7，所述的辅助压板6位于上盖1的上方且通过支撑臂7与底座5转动连接。辅助压板采用凹槽结构，可以罩在上盖外，与原有订书机容易配合，整体性和稳定性都好。
本实施例中，所述的辅助压板6与上盖1之间设有带动上盖1摆动的连接机构具体为：所述的辅助压板6与上盖1直接设有压杆8，所述的压杆8安装在上盖1上，所述的辅助压板6上凹槽的两侧内壁还分别设有滑槽9，所述的压杆8的两端分别在辅助压板6的滑槽9内，并可以在滑槽内滑动，滑槽可以引导压杆移动，这种结构最为简单。
所述的压杆8可转动地固定在上盖1上，这样在订书机工作时，压杆8也可以在滑槽9内转动，避免辅助压板和上盖错位，不影响辅助压板和上盖的正常工作，所述的钉板4与底座5之间的活动连接更好为滑动连接，滑动连接可以采用常规方式，比如底座5侧边设置滑道，钉板4二侧直接置于滑道中滑动。
本实施例中钉板和底座的滑动连接方式为：还包括滑块10，所述的钉板4与滑块10由螺钉连接，滑块的尾部还设置卡口20，钉板尾部插在卡口20内，然后用螺钉连接，这样可以避免钉板4晃动。
所述的底座5设有滑道11，所述的滑道11的两侧设有卡槽12，所述的滑块10设有滑条13，所述的滑块10位于滑道11内且滑块10两侧的滑条13滑动配合在卡槽12内。这样，既能保证滑块的稳定，又便于滑块的移动。
正常位置时，钉板4和滑块10前部由滑道11前端53限位，并通过锁紧机构而锁紧。为更省力，需将钉板从正常位置调整到省力位置，调整钉板位置后，通过锁紧机构将钉板4锁住，这样能更好地工作。
所述的锁紧机构包括按钮，所述的按钮和钉板或底板卡扣配合，关闭按钮时，钉板与底板扣住而无法移动，开启按钮时，钉板与底板脱离而可以移动。
本实施例的锁紧机构包括：扣钩14，所述的扣钩转动安装在底座5上；滑块，所述滑块上设有用于扣钩配合的缺口15；开关，所述的开关设在底座上，控制扣钩14的启闭，本实施中开关采用下述的顶柱17；挡块21，所述的挡块位于滑条13下方；挡板22，所述的挡板设在滑道的尾部，用于阻制挡块；这样滑块移动到省力位置时，挡板挡住滑条上的挡块，再按下(关闭)开关，扣钩插入滑块上的缺口而阻止滑块滑动，滑块由扣钩和挡板前后限位而锁住，从而使装订机构能够正常装订；开关开启时，扣钩脱离滑块上的缺口而使滑块能够滑动，从而使装订机构能够改变装订位置。
理论上，滑块的位置可以根据需要调整至任意位置，然后通过锁紧机构锁紧即可。本实施例中，订书机只需要正常位置和省力位置两个位置，相对应的滑块也只需要二个位置，因此，对滑块进行限位的缺口15只需一个，只要省力位置时，扣钩14能扣入滑块缺口15而锁住即可。
更具体地，所述的扣钩14包括主体，所述的主体中部30与底座5转动连接，所述的主体的一端设有钩板16，所述的钩板16与滑块10上的缺口15配合，主体另一端为平板28，其靠近底座滑槽的侧壁，所述的底座5上设有与主体另一端相对的插孔(图中未画出)，所述的插孔内设有顶柱17，顶柱的两端设有凸块25，两个凸块正好将顶柱限位在插孔内， 凸块之间的长度大于底座侧壁的厚度，因此，顶柱17可以卡在插孔内且来回自由滑动，所述的顶柱17与扣钩14的主体的另一端平板28相抵，顶柱按下时推动平板28而使主体旋转，主体钩板16进入滑块10上的缺口15而锁住滑块10；当拉出顶柱17时，顶柱17离开平板28而解除对主体的限制，滑块可由外力移动，这样可通过按下顶柱17使扣钩和滑块钩住，或者拉回顶柱17允许扣钩和滑块脱离。
为了保证扣钩14的稳定性，所述的底座5的滑道11内设有挡块18，所述的扣钩14主体上相对挡块18的另一侧设有凸钮27，所述的挡块18和凸钮27配合形成限制扣钩14主体过度摆动的结构，见图7。通过挡块和凸钮，限制了扣钩的活动范围，避免扣钩在滑槽内脱落。
还包括尾盖19，所述的尾盖19罩在上盖1和钉道组件2的连接处，所述的尾盖19的前端与上盖1连接，所述的尾盖19与支架座3转动连接。尾盖19对上盖和钉道组件的连接处起到保护作用。
所述尾盖的前端设有卡扣23，上盖上设有卡孔24，所述卡扣卡入卡孔中连接，这样能更方便地固定尾盖。
参见图12，正常位置时，根据杠杆原理可知：F*L＝F1*L1，F1＝F*L/L1，F1＝F*106/67＝1.58*F；F2*L3＝F1*L2，F1＝F2*L3/L2，F1＝F2*101/45＝2.24*F2，得到：2.24*F2＝1.58*F，F2＝1.58/2.24*F＝0.70*F，可省力30％。
参见图13，钉板移动至省力位置时，根据杠杆原理可知：F*L＝F1*L1，F1＝F*L/L1，F1＝F*106/67＝1.58*F；F2*L3＝F1*L2，F1＝F2*L3/L2，F1＝F2*101/26＝3.88*F2，得到：3.88*F2＝1.58*F，F2＝1.58/3.88*F＝0.40*F，可省力60％。
从上可知，本发明设置辅助压板就能实现比常规订书机省力的效果，移动钉板至省力位置后，可以达到省力60％的效果。
从图12、图13可知，一般情况下有如下公式：F2＝F*(L/L3)*(L2/L1)；订书机从正常位置到省力位置，钉板4相对底座5后移，L、L3不变，L2很小变化，而L1增加很多，因此，如果钉板移动至省力位置时，施力F2比原始正常位置的施力F大大减小。
实施例2。
如图13-23所示，省力订书机，其包括：上盖1、钉道组件2、钉板4、底座5，所述的上盖1外设有辅助压板6，所述的辅助压板6与上盖1通过压杆8滑动连接，所述的钉板4与底座5滑动连接。
本实施例与实施例1相比，主要有下述不同之处。
所述的压杆8二端分别固定滑动件81，滑动件81滑动配合在辅助压板6的滑槽9内，这样压杆8能更好地滑动。
所述的钉板4与底座5的滑动连接方式发生变化，所述的钉板4设有辅助板41，所述的辅助板41位于钉板4下方，所述的钉板4与辅助板41固定，辅助板和钉板之间的固定形式不限，用螺钉、销柱、焊接等等方式均可，所述的底座5的二侧边上设有滑动槽51，辅助板41的二侧进入滑动槽51内，可在滑动槽51引导下移动，从而使钉板4在底座5上滑动。通过钉板安装辅助板，可以有效避免对钉板结构的影响，而且制造起来更为便利。
实施例1订书机从正常位置和订书机省力位置变换中，钉板与底座的滑动均需要手动操作，本实施例中，钉板与底座设置复位机构，具体为压簧，正常位置位置时，压簧处于爱压状态，见图21，由正常位置向省力位置变化时由压簧回复驱动，见图23，比较省力。
本实施例中，所述的锁紧机构包括前锁紧机构和后锁紧机构，所述的前锁紧机构对订书机正常位置的定位，后锁紧机构对订书机省力位置的定位，具体为对钉板4和底座5在这二个位置时进行定位。
本实施例的前锁紧机构具体为：所述的辅助板41上设有解锁槽42，所述的解锁槽42的后端为槽扩大后形成的卡口43，对应订书机正常位置；所述的解锁槽42的前端为沿解锁槽42扩张后形成的让位口44，对应订书机省力位置。
所述的按钮77包括按钮部771、锁定部772，锁定部772与解锁槽42宽度相配合，其在解锁槽42中可移动，底座5侧壁上设置按钮孔57，按钮部771置于按钮孔57中，所述的按钮77锁定部772进入卡口43时抵住卡口43，限制辅助板41移动。
所述的后锁紧机构具体为：其包括滑道51上方设有的阻挡件52和钉板4上设有的挡口42及压簧48，所述的阻挡件52和挡口42相抵而使钉板4限位，此时，压簧48阻止钉板4后退。
所述的底座上设有压簧槽46，辅助板41上设有压簧座47，压簧48位于压簧槽46内，其一端与底座相抵，另一端与压簧座47相抵，订书机平常状态时，压簧48受压簧座47压缩；订书机需省力位置时，通过按钮77解除辅助板41锁定，压簧48驱动辅助板移动，从而带动钉板4、钉道组件2、上盖1、辅助压板6至省力位置，进行省力装订。
为方便按钮操作，所述的按钮77与底座5之间设有复位弹簧55，所述复位弹簧55的一端与底座5连接，另一端与按钮77连接，按钮锁定部772由卡口43挡住，此时复位弹簧55处于自然状态。当按下按钮，复位弹簧55开始压缩，按钮锁定部772移动至与解锁槽42正对，钉板在压簧48弹力作用下后移至按钮锁定部772处于让位口44位置，按钮锁定 部772会被复位弹簧55推动至让位口44内，限位弹簧再次处于自然状态，按钮复位，这样按钮操作方便，按钮的表面能与底座的侧壁保持在同一平面上，也较为美观。
所述让位口44与解锁槽42之间还设置弧线441过度，使钉板往回移动时按钮锁定部772能顺利进入解锁槽42，防止按钮锁定部772被让位口44卡住。
如同实施例1所示，正常位置操作时，本发明订书机可以作为正常的省力订书机使用。
当需要更加省力时，即进入省力位置，按压按钮，使按钮锁定部772从辅助板底部的卡口43中向里移动至锁定部772与解锁槽42正对时，同时回复弹簧75受压，钮锁定部772解除对辅助板41的阻挡，辅助板在压簧48的回复力作用下从辅助板底部的卡口43脱离，在解锁槽42的引导下顺着按钮锁定部772往后移动，直至阻挡件52和挡口42而定位，此时，按钮锁定部772在回复弹簧75的弹力作用下进入让位口44，在此过程中，辅助板带动钉板4、钉道组件2、上盖1、辅助压板6均移动至省力位置，辅助压板和上盖之间通过滑动实现相对移动，从而延长了辅助压板的施力力臂，装订时比较省力，具体见实施例1的说明。
当要回复正常位置时，用手推动上盖或其他与上盖组合在一起的部件，驱使辅助压板441沿弧线441使锁定部772从让位口44移至解锁槽42并由解锁槽42引导，至锁定部772对准卡口43位置时由回复弹簧15驱动锁定部772进入卡口43而将辅助压板441锁住。
