如图1、图2和图3所示，输料机构包括：枪膛1、设在枪膛1内的推动组件2、设在枪膛1上的弹性转动组件3以及设在枪膛1内的棘轮4。其中棘轮4与料带5啮合，料带5上排列有若干铆钉，当推动组件2推动一次后，棘轮4会沿一方向转动一固定角度，将料带5移动位置，将铆钉传输至打钉位，推动 组件2连续推动时，铆钉将依次传输至打钉位。自动将铆钉输送至打钉位置，提升了工作效率，避免了工人因操作失误而受伤的情况。
其中，如图3所示，推动组件2沿竖直方向设置，推动组件2的推动方向也沿竖直方向，铆钉枪在打钉时，推动组件2会被向下推动。推动组件2具有初始位和推动位，初始位高于推动位，铆钉枪打钉时，推动组件2从初始位被推动到推动位。结合图2与图3，其中推动组件2包括可滑动地设在枪膛1内的顶针21、可滑动的设在枪膛1内的昆仑柱22，昆仑柱22位于顶针21下方。推动组件2位于初始位时，如图3所示，顶针21高于昆仑柱22并与昆仑柱22分离；推动组件2切换到推动位时，如图4所示，顶针21下移抵住昆仑柱22并带动昆仑柱22下移。
弹性转动组件3与推动组件2的昆仑柱22相抵，当推动组件2从初始位切换到推动位时，昆仑柱22会带动弹性转动组件3从第一位置切换到第二位置。如图2和图3所示，弹性转动组件3包括：可转动地设在枪膛1内的摆块31、连接在枪膛1和摆块31之间的弹性件32，本实施方式中弹性件32为拉簧，当然弹性件32也可以为其他部件，本实施方式中仅以拉簧为例，不做具体限定。枪膛1上开设有一凹槽11，拉簧的上端固定在凹槽11的上部分内；凹槽11的下部分贯通枪膛1，拉簧通过凹槽11的下部分与枪膛1内的摆块31连接。摆块31与推动组件2的昆仑柱22相抵。图3中推动组件2位于初始位，弹性转动组件3的第一位置。由图中可知，当推动组件2在初始位时，昆仑柱22与摆块31相抵，但昆仑柱22对摆块31未施加作用力，弹性件32处于放松状态，此时为弹性转动组件3的第一位置。图4中推动组件2位于推动位，弹性转动组件3位于第二位置，由图中可知，当推动组件2切换到推动位置时，下移的昆仑柱22会推动摆块31在枪膛1内转动，同时转动的摆块31会拉伸弹性件32的一端， 弹性件32处于拉伸状态，此时为弹性转动组件3的第二位置。结合图1与图2，枪膛1上设有盖板12，盖板12将凹槽11封闭，避免弹性件32裸露在外，降低弹性件32受损、生锈的概率，延长弹性件32的寿命。当启动铆钉枪时，结合图3与图4，推动组件2从初始位切换至推动位，推动组件2带动弹性转动组件3从第一位置切换到第二位置；铆钉枪打钉完成后，弹性转动组件3通过弹性件32的弹力从第二位置回弹至第一位置，同时也带动推动组件2回到初始位置。
如图5所示，弹性转动组件3还包括：设在摆块31上的卡接部件33，棘轮4在圆周方向上设有多个卡接位，卡接部件33可以卡接在棘轮4上任意一个卡接位上。结合图5与图6，其中棘轮4在圆周方向上具有第一方向V1和与第一方向V1相反的第二方向V2，棘轮4沿第一方向V1单向传动，以传输料带5。棘轮4与摆块31同轴设置，但棘轮4与摆块31之间存在一定间隙，摆块31在转动时不会因接触而干扰棘轮4。如图7所示，卡接部件33在朝第二方向V2移动时，可在棘轮4上切换卡接位；卡接部件33在朝第一方向V1移动时，无法切换卡接位，可带动棘轮4运动。当弹性转动组件3从第一位置转动至第二位置时，其转动方向为第二方向V2，使卡接部件33从与一卡接位卡接的状态，切换至与第二方向V2上的下一卡接位卡接，此过程中，棘轮4静止不动。当弹性转动组件3从第二位置回弹至第一位置时，转动方向为第一方向V1，此时卡接部件33无法切换卡接位，弹性转动组件3通过卡接部件33带动棘轮4朝第一方向V1转动一定位置，棘轮4带动啮合的物料带移动，实现一次送钉。
其中，如图5所示，摆块31包括：同轴设置的两个摆动部311、连接在两个摆动部311之间的连接部312，结合图3，摆动部311与推动组件2的昆仑柱22相抵，其中昆仑柱22上设有滚轮221，摆动部311有部分为弧形面，滚轮221与弧形面相抵，滚轮221与弧形面之间为线接触，可以大大减小推动组件2与 摆动部311相对运动时的摩擦力，延长机构寿命。结合图5与图6，连接部312位于棘轮4外与棘轮4之间具有一定间隙，避免连接部312随摆动部311转动时接触。棘轮4也形成有两个，分别为左轮和右轮，两棘轮4均与料带5啮合，提升料带5传输的稳定性。连接部312上朝棘轮4方向凸起形成有安装部3121，安装部3121位于左轮与右轮之间，安装部3121上开设安装孔，卡接部件33设在安装孔内与棘轮4卡接。结合图7，棘轮4的卡接位为开设在棘轮4上的弧形槽41，弧形槽41开设在棘轮4内侧，卡接部件33包括：位于安装孔内的压缩弹性件332、至少部分凸出于安装孔的卡接球331，卡接球331的数量可以为一个或两个，当卡接球331的数量为1时，压缩弹性件332一端固定，另一端与卡接球331连接，将卡接球331抵在棘轮4的弧形槽41内。弧形槽41具有一顶点，且顶点在第一方向V1具有第一弧形面441，在第二方向V2具有第二弧形面442，第一弧形面441的弧度大于第二弧形面442的弧度，卡接球331在随摆块31沿第二方向V2移动时，卡接球331可以沿第二弧形面442滚动至下一弧形槽41内；当卡接球331随摆块31沿第一方向V1移动时，由于第一弧形面441的弧度较大，卡接球331无法在第一弧形面441上移动，卡接球331与弧形槽41始终处于卡接状态，使得卡接球331在第一方向V1上移动时会带动棘轮4转动。
由于弹性转动组件3每次从第二位置切换到第一位置时转动的角度均相同，即每次推动组件2被推动后恢复原位时，弹性转动组件3从第二位置切换到第一位置，棘轮4转动一定角度，将料带5移动一定距离，料带5移动的距离等于料带5上相邻两个铆钉之间的间距。
作为优选的，本实施方式中的卡接球331数量为两个，两个卡接球331可以更加均衡的带动两个棘轮4运动，从而使得料带5移动地更加稳定。左轮和 右轮上也均开设弧形槽41，左轮的弧形槽41与右轮的弧形槽41数量相同且一一对应。压缩弹性件332设在安装孔内，本实施方式中压缩弹性件332为压簧，当然，压缩弹性件332也可以为其他具有弹性的部件，本实施方式中仅以压簧为例，不做具体限定。压缩弹性件332的两端分别连接卡接球331，连接方式可以为焊接或通过环体连接；或压缩弹性件332两端与卡接球331相抵。两个卡接球331均有部分位于安装孔外，安装孔的孔径大于卡接球331的外径，使卡接球331可以自由进出安装孔。卡接球331位于安装孔外的部分卡入弧形槽41内，使卡接球331不会与安装孔脱离。
另外值得注意的是，如图5所示，摆块31的摆动部311上开设有与安装孔同轴的球孔313，球孔313的内径大于或等于安装孔的内径，卡接球331可以通过球孔313进入安装孔内。若两卡接球331固定连接在压缩弹性件332的两端，整个卡接部件33可以通过球孔313安装入安装孔内。
结合图1与图8，枪膛1下方设置有底座6，枪膛1具有一开口，料带5从枪膛1的开口进入传输到底座6上，枪膛1上的盖板12向开口延伸有限位板，限位板用于限定料带5的运动轨迹，底座6上端面形成有弧形凸起，且打钉位位于底座6上，弧形凸起也用于引导料带5的运动，使料带5的移动轨迹稳定，料带5上的铆钉可以稳定停留在打钉位。
在铆钉枪中，用户一般通过扣动扳机完成铆钉的打钉，扣动扳机前底座6上的打钉位上具有料带5的铆钉，扣动扳机之前，如图3所示，推动组件2位于初始位，弹性转动组件3位于第一位置。扣动板机，通过铆钉枪头的活塞杆对推动组件2施加作用力，使推动组件2下移，推动组件2的顶针21下压推动昆仑柱22，推动组件2到达推动位，昆仑柱22推动摆块31，摆块31转动同时带动拉簧拉伸，以及卡接部件33从棘轮4的一个卡接位内移动至另一个卡接位 内，使弹性推动组件2切换到如图4中的第二位置，此时顶针21将打钉位的铆钉打出。一次打钉完成后，用户释放扳机，铆钉枪头的活塞杆拉动顶针21，使推动组件2回到初始位，此时摆块31上不再受昆仑柱22的抵压，使得拉簧复位，从而拉动摆块31复位，弹性转动组件3回弹至第二位置，将昆仑柱22和顶针21顶起，使推动组件2回到图3中的初始位，同时通过卡接部件33带动棘轮4转动，料带5向前传动一定距离，使下一颗铆钉位于打钉位上，为下次打钉做准备。
本发明的第二实施方式涉及一种铆钉枪头，包括如第一实施方式中的输料机构。
以上所述实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
以上所述实施例仅表达了本发明的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对发明专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干变形和改进，这些都属于本发明的保护范围。因此，本发明专利的保护范围应以所附权利要求为准。
