所述第二输入部位12基于熔接工作电机200的驱动而产生第一方向的转动，而使中间连接部件1产生第一方向的转动，使第一输入部位11被连接到所述第一输出部件201上。
所述熔接装置设置熔接工作活动组件的熔接工作状态锁紧结构，所述锁紧结构倾斜设置，锁紧结构的上端和锁紧结构连接部位13通过轴21铰接，轴21和轴10平行，锁紧结构的下端和熔接工作活动组件转动连接；所述熔接装置设置限位结构，以当熔接工作进行时，限定中间连接部件1向第二方向转动的最大转动角度，在该最大转动角度时，扇形齿轮和输出部件之间已经脱离，所述限位结构由在手提打包机机架上的挡位101和在中间连接部件1上的挡块14配合构成。
以上锁紧结构的优选结构是所述锁紧结构由上部组件和下部组件组成，上部组件设置第一连接件24，由所述连接件24与熔接工作下压锁紧输出连接部位13通过轴21铰接，下部组件设置第二连接件25，由第二连接件25与熔接工作活动组件转动连接，上部组件和下部组件之间设置压簧22，上部组件中的第一连接件设置螺母26而螺纹连接长度调节件23，所述长度调节件23插入第二连接件25中；所述锁紧结构、熔接工作活动组件、中间连接部件1被配置为：在熔 接工作进行时(见图6)，锁紧结构处在锁紧状态，并且，第一输入部位11和第一输出部件201处于脱开状态，中间连接部件1保持向第二转动方向转动的趋势，锁紧结构与锁紧结构连接部位13转动连接的转动轴线处在平面的第一侧外；在熔接工作起始前(见图5)，熔接工作活动组件处在上抬状态，锁紧结构处在非锁紧状态，锁紧结构与锁紧结构连接部位转动连接的转动轴线处在平面的第二侧外，第一输入部位11和第一输出部件201处于连接状态；所述平面为经过中间连接部件的转动轴线和熔接工作活动组件与锁紧结构转动连接的转动轴线的平面，第一侧和第二侧分为所述平面的正反两侧。
所述熔接工作活动组件包括安装架31，所述安装架31通过轴承32可转动地安装在安装座100上，所述安装架31还通过熔接工作状态锁紧结构与中间连接部件连接，具体地，所述安装架31通过销轴27与第二连接件25转动连接。这样，所述中间连接部件1在第二方向上的转动通过所述锁紧结构使熔接工作活动组件转动到熔接工作角度并被锁紧而不反向转动。
所述熔接工作活动组件包括安装架31和安装座100之间设置安装架的上顶弹簧37。
所述熔接工作活动组件包括熔接工作件33和熔接工作动力输入连接件34，熔接工作件33和连接件34铰接，熔接工作动力输入连接件34通过偏心轴35和传动机构202的一端连接，所述传动机构202可以是皮带传动机构，偏心轴35和所述传动机构的从动轮203连接，所述传动机构的主动轮204和熔接工作电机的输出轴205连接；所述熔接工作件33滑动连接于安装架31上的导轨36，可以在它们的侧面之间的圆弧槽设置卡接滚珠，而将熔接工作件33可滑动地连接于导轨36上；所述熔接工作件33和熔接工作动力输入连接件34的铰接轴线与安装架31的转动轴线平行，同时也平行于偏心轴35。
所述熔接工作电机200与传动机构202之间为单向传动连接关系，在中间连接部件1被熔接工作电机200驱动而做第一方向运动时，所述熔接工作电机200 与传动机构202之间处于脱离驱动连接关系，熔接工作电机200对传动机构202不产生驱动。这可以在主动轮204和熔接工作电机的输出轴205之间通过相应方向的单向轴承连接即可。
所述熔接工作电机200与第二输入部位12之间为单向传动连接关系，但是与所述熔接工作电机200与传动机构202之间为单向传动连接关系的方向相反，在中间连接部件被熔接工作电机200驱动通过第一输入部位11的输入连接而做第二方向运动时，所述熔接工作电机与第二输入部位之间处于脱离驱动连接关系，中间连接部件由第一输入部位接受到的电机驱动力被驱动旋转。
所述熔接工作电机200被配置为在熔接工作结束后自动反向转动，这可以通过对熔接工作时间的设定来获得自动反向转动的信号，并通过与第二输入部位12的连接，使得所述中间连接部件1产生第一方向的复位转动。当手提打包机开机时，一旦接通电源，熔接工作电机200也先按该反向方向工作，使得装置复位。
所述第二输入部位12也采用一定扇形角度的扇形齿轮，熔接工作电机200通过第二输出部件206能够带动第二输入部位12产生第一方向的转动，所述第二输出部件206也采用齿轮，对于所述第二输出部件206的单向驱动，也可以采用和熔接工作电机的输出轴205之间通过相应方向的单向轴承207连接即可。
由此，本发明可以将第一输出部件201、第二输出部件206及传动机构的主动轮204均安装在熔接工作电机的输出轴上，从而简化能够基于本发明的方案而获得无复位手柄操作的自动控制和极大地简化结构。所述复位是指中间连接部件发生第一方向的转动，使熔接工作活动组件能被打开至在熔接工作活动组件和熔接工作固定组件之间能放入打包带的状态，当中间连接部件发生第一方向的转动后，该打开可以依靠所述复位弹簧37自动进行。
所述第一输入部位11的扇形齿轮在所述第一方向上的前端设置与第一输出部件201配合的弹性拨齿，从而能够在中间连接部件1进行第一方向复位转动时 能够具有广泛的适应性，保障手提打包机整体工作的自动衔接进行。所述弹性拨齿采用金属弹片5并通过连接结构连接在扇形齿轮在第一方向上的前侧面15上。扇形齿轮本体在所述第一方向上的前端第一个齿16为前侧面带有缺口17的半齿，弹片5即处在该缺口17前面，并利用该缺口17形成弹片的凌空部位而发挥弹性。
所述熔接工作固定组件为手提打包机底部的不动结构，上表面设置固定摩擦结构4，所述熔接工作件33与固定摩擦结构4配合，通过摩擦而使得打包带的接头发热熔接。
工作时，在熔接工作状态，熔接工作电机200根据设定的时间进行正转一定时间，打包带接头熔接，在该时间结束后，在没有人工介入的情况下，所述熔接工作电机200根据设定的时间间隔而得到反转信号。
在熔接工作电机200开始反转时，由第二输出部件206和第二输入部位的配合而整个中间连接部件1发生第一方向的转动(图6中的顺时针方向)，由此，第一输入部位11从与第一输出部件处于脱开状态转至两者啮合，并继续转动至图5位置，但是，由于所述熔接工作电机200与传动机构202之间为单向传动连接关系，因此，此时传动机构不反向转动。而锁紧结构连接部位13在发生第一方向转动后，倾斜的锁紧结构和锁紧结构连接部位13之间的转动轴线也转至前述平面的第二侧外，锁紧结构由此解除锁定，安装架31能够被转动抬起复位，而可以去除粘结好的打包带，同时再放入需要打包和熔接的打包带(见图5状态)。
在进行下个循环的打包工作时，可以按下启动开关，打包带先被拉紧装置拉紧，当打包带被拉紧时，拉紧装置的驱动电机的电流发送变化而使熔接工作电机200得到信号，熔接工作电机200自动开始正转工作，使得输出部件201由其驱动转动，第一输入部位11被驱动向第二方向转动，并由此整个中间连接部件1被向第二方向转动，倾斜的锁紧结构和锁紧结构连接部位13之间的转动轴线也转至前述平面的第一侧外，实现锁紧，在该状态下，所述压簧22使得中间连接部件1保持向第二转动方向转动的趋势，而使得挡块14顶紧于限位结构的挡位 101上，并在压簧22的作用下，将安装架31下压至熔接工作角度进入熔接工作状态，此时，第一输入部位11刚好运动至与第一输出部件201脱开(见图6)。与此同时，由于所述熔接工作电机200与第二输入部位12之间为单向传动连接关系，第二输入部位12仅为随中间连接部件1转动至相应角度。
在熔接工作状态，熔接工作电机200通过传动机构202、偏心轴35、熔接工作动力输入连接件34带动熔接工作件33在导轨36的导向下来回运动，进行熔接工作。与此同时，由于所述熔接工作电机200与第二输入部位12之间为单向传动连接关系，第二输入部位12不被驱动转动，不对所述锁紧状态产生干涉。与此同时，由于扇形齿轮已脱离输出部件201(见图6)，并且由所述锁紧结构保持状态，从第一输入部位11来说，也不会对锁紧状态产生干涉。所以中间连接部件1保持正常工作状态而不会被干涉。
当熔接工作结束后，再开始熔接工作电机200的前述反转工作。
参照图9、10、11、12，在图9-12中与图1-8相同的标号的含义，请参阅上述实施方式记载。
在本实施例中，第一输入部位11和第一输出部件201的离合连接结构包括有以下结构：
所述电机输出齿轮201设置轴孔212，电机输出轴205穿入所述轴孔212，在所述电机输出轴205和所述第一输出部件201(以下称为电机输出齿轮)之间设置扭簧214；所述电机输出轴205和电机输出齿轮201之间在周向上有一段间隔G，所述电机输出轴205具有第一驱动部位2051而驱动第一输入部位11的扇形齿轮第二方向转动，所述电机输出轴205具有第二驱动部位2052而在扇形齿轮11从与电机输出齿轮201脱离转为连接状态后驱动第一输入部位11的扇形齿轮第一方向转动。
所述扭簧214的工作方向为，在第一输入部位11的扇形齿轮转动一定角度后与电机输出齿轮201脱离之后，电机输出轴205停止转动时，驱使电机输出齿 轮201继续转动，使电机输出齿轮201(本实施例中的凸起215)脱开与第一驱动部位2051的连接，并与第二驱动部位2052接触。所述间隔G所对应的圆心角小于第一输入部位11的扇形齿轮的相邻齿之间的角度。
所述电机驱动轴205与电机输出齿轮201连接的部位为扁轴，其两侧的平面作为第一驱动部位2051和第二驱动部位2052，所述电机输出齿轮201的电机轴孔212设置有凸起215，凸起215的两侧分别与电机输出轴的第一驱动部位2051和第二驱动部位2052配合，而能够被双向带动。
所述电机输出齿轮201上端面设置扭簧连接孔216，所述扭簧214套在扁轴上，所述扭簧214的一端217插入所述扭簧连接孔216中而与扭簧连接孔216连接，所述扭簧216具有与扁轴的形状匹配的扁弹簧圈而与所述扁轴连接。
通过所述周向上的间隔G和扭簧214，能够在第一输入部位11的扇形齿轮进行复位方向转动时，电机输出齿轮201能够有一定的相对于电机输出轴205的转动角度，具有广泛的适应性，避免第一输入部位11的扇形齿轮和电机输出齿轮201之间发生卡死现象，保障手提打包机整体工作的自动衔接进行。
